NORTHWEST BENIN SITES AND SOCIALLY DETERMINED ARTIFACT DISTRIBUTION By Idemudian Omokhodion A DISSERTATION Submitted to Michigan State University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Department of Anthropology 1987 5" 7' 3773’ Copyright by Idemudian Omokhodion 1987 All Rights Reserved ABSTRACT NORTHWEST BENIN SITES AND SOCIALLTY DETERMINED ARTIEACT DISTRIBUTION By Idemudian Omokhodion The mode of evolution of the ancient kingdom of Benin southwestern Nigeria, is of research interest in the way oral historical data has been related, for example, to archaeological evidence. Carbon 14 dates and related evidence from the city center indicate that the kingdom was established at about 700 years ago. Specific determinants such as the territoriality associated with the unique pattern of earthworks have been offered as explanation for this origin. New evidence provided by this research is in the form of artifact (especially pottery) distribution on the northwest of the Benin City center. The genera1.variability of pottery design attributes has been found to be explained by the mobility of women in post-marriage residence and the characteristic non-sororal polygyny. Values placed on residence and marriage to several wives are vividly. illustrated in Benin architecture, and elaboration of these values in mythology and office regalia could account for the distinctive kingship and caste systems. This deduction is not inconsistent with the evidence of Benin-Ife relationship since Benin shares several cultural features with the Yoruba states. Dedicated to Dr. Aku Omokhodion ACKNOWLEDGEMENTS I wish to say this, that it would be hard for me to capture in words the gratitude I feel towards my Department (Anthropology) at Michigan State University, under the leadership of Dr. B. Gallin, for the ready assistance I got throughout my graduate program. I wish I had something to give back in return. Secondly, I could not have gone half way if I did not have my academic advisers, Dr. Cleland, Dr. Dwyer, Dr. Lovis and Dr. Robbins, who understood my problems in a personal way. They provided me with very helpful hints and comments before and during the preparation of my dissertation. In particular, I am personally indebted to Dr. Robbins who used his time and money, outside of the official requirements, to help me through the program. Dr. Robbins also readily read through my drafts and I am inspired by his recognition and commitment to scholarship. I must express my gratitude to the Department secretaries who have done a lot to make my stay in the Department a lot easier, and in particular, Barbara Knuth. I always felt reassured by her smiles. vi Without a research grant from the L.S.B. Leakey Foundation it would have been very difficult to carry out my fieldwork. I am grateful for this and also to the University of Benin for the grant I obtained from them at the initial stages of planning. Thanks also go to Dr. Fred Anozie who used his money to travel all Ithe way from Nsukka to act as my local field supervisor in the Benin project. At various points of my fieldwork in Benin, several assistants were very helpful and I thank them all. And lastly I must thank these my editors for their assistance. They are Dr. Kofi Egbo, Ms Carol Bacak, and Mrs Virginia Bacak. vii TABLE OF CONTENTS List of Tables .................................... x List of Figures .................................. xii CHAPTER I INTRODUCTION 1.1 Background to Historical Reconstruction in Nigeria ..................................... 1 1.2 An Anthropological Perspective ................. 5 1.3 Purpose of the Study .......................... 10 II BENIN RESEARCH 2.1 Ecology ....................................... 13 2.2 Benin Society ................................. 32 2.3 Benin Art ..................................... 40 2.4 Benin in West African Architecture ............ 44 2.5 Historical Sites .............................. 50 2.6 Benin Archaeology ............................. 55 2.7 A Summary of West African Ceramics, Historical Perspective and the Place of Benin Materials ............................ 60 2.8 Benin in West African Trade and and State Formation ........................... 66 2.9 Summary ....................................... 73 III METHODOLOGY 3.1 Assumptions ................................... 75 3.2 Fieldwork on the Northwest 1 .................. 79 3.3 Eko Abetu Site ................................ 94 3.4 Uwan Wall Site ................................ 98 3.5 Evboneka Farm Site ............................ 99 3.6 Summary ...................................... 100 IV FIELDWORK ON THE NORTHWEST 2 4.1 Uwan Living Site ............................. 104 viii VI VII VIII CLASSIFICATION AND ANALYSIS 1 5.1 Northwest Benin Pottery ...................... 115 5.2 Quantitative Analysis ........................ 117 5.3 Qualitative Analysis ......................... 156 5.4 Dating ....................................... 162 5.5 Summary ...................................... 163 CLASSIFICATION AND ANALYSIS 2 6.1 Qualitative Analysis ......................... 164 6.2 Quantitative Analysis ........................ 195 INTERPRETATION 7.1 Bias ......................................... 199 7.2 Interpretive Models .......................... 203 7.3 Historical Implications ...................... 215 7.4 Discussion ................................... 217 SUMMARY AND CONCLUSIONS .......................... 221 Footnotes ........................................ 226 List of Reference ................................ 230 Appendix A -- Plates ............................. 243 ix E e coooqmmpweop 10 11 12 _ 13 14 15 16 17 18 19 LIST OF TABLES PAGE Trench B1, Tool Inventory, Eko Abetu Site ........ 101 Trench X2, Tool Inventory, Eko Abetu ............. 102 Trench Y2, Tool Inventory, Eko Abetu ............. 103 Trench 410, Tool Inventory, Uwan Site ............ 113 Trench 420, Tool Inventory, Uwan Site ............ 114 Rim Nominal Scores, Trench B1, Eko Abetu ......... 121 Rim Nominal Scores, Trench X2 Eko Abetu ......... 122 Rim Nominal Scores, Trench Y2, Eko Abetu ......... 123 Jaccard Coefficient for Rim Variables, Eko Abetu ........................................ 124 T-Test Sample Means for Lip Thickness, Eko Abetu ........................................ 125 T-Test Scores for Lip Thickness, Eko Abetu ....... 126 Body Decorated Scores, Trench B1, Eko Abetu ...... 127 Body Decorated Score, Trench X2, Eko Abetu ....... 128 Body Decorated Scores, Trench Y2, Eko Abetu ...... 129 Chi-Square Determinations for Body Decorated Scores, Eko Abetu .................. 130-135 Diagnostic Vessel Count, Eko Abetu ............... 136 Diagnostic Vessel Count, Uwan Site ............... 169 Rim Nominal Scores, Trench 410, Uwan Site ........ 170 Rim Nominal Scores, Trench 420, Uwan Site ........ 171 X 20 21 22 23 24 25 26 27 28 Jaccard Coefficient for Rim Variables, Uwan Site ........................................ 172 Body Decorated Scores, Trench 410, Uwan Site ..... 173 Body Decorated Scores, Trench 420, Uwan Site ..... 174 Chi-Square Deterinations for Body Decorated Scores, Uwan Site .................. 175-178 Weight of Sherd Analysis, Weight of Sherd Analysis, Weight of Sherd Analysis, Weight of Sherd Analysis, Weight of Sherd Analysis, xi Trench B1, Eko Abetu...179 Trench X2 .............. 180 Trench Y2 .............. 181 Trench 410, Uwan ....... 182 Trench 420, Uwan ...... .183 LIST OF FIGURES FIGURE PAGE 1 Map of West Africa ................................. 9 2 Geological Map of Benin ........................... 17 3 Map of Nigeria -

In some instance, out-right pessimism has been expressed about the significance of archaeological classification and typology for historical reconstruction in West Africa. The aim of this study is to demonstrate that on the contrary, there are new approaches to archaeological analysis which can be used as means to "decode" aspects of past social organisation in ways that would potentially be of great interest to historians and others. In this dissertation, this historical point is initially addressed through a brief survey of Afigbo's paper (1977:81-98), titled "Facts and myths in Nigerian Historiography". The point is made through a consideration of three historiographical traditions in Nigeria. The three traditions are a) Precolonial, b) Colonial and c) Nationalist historiographies. 1.1 WMWWMW- 1.11 W W. Afigbo (1977) has suggested that precolonial historiographical tradition in Nigeria can be discussed by reference to the Forest peoples on one hand, and the Grassland peoples on the other. Forest historiography is of two types. The first consists of "myths and legends" in the 1 2 folk tradition of the people, in which origin is attributed to the actions of the supernatural, animals and inanimate objects. This can be observed for example, amongst the Igbo, Yoruba and the Bini, whose legends recall the role of nature and supreme deities in different acts of creation of their lineages and clans. Each group, explains its own creation to include the creation of the entire world - "an amazing combination of the narrowest egocentrism and localism with an all embracing universalism" (Afigbo 1977:84) Afigbo sees this historiographical technique as partly "irrational", but that, it is often complemented by a second type of traditional historiography, which includes “accounts of actual heroes and heroines". (Afigbo 1977:85) This second type of accounts, comes in the form of ritual incantations, praise and festive songs, poems, proverbs, chants, folktales and so forth. While, the myths and legends deal with the remote past of the supernatural, the second type deals with the recent past of real human acts and deeds. Amongst the Grassland peoples, on the other hand, Islamic influence from about the 7th century, introduced with it, Arabic literacy, including the ”Mecca-centric" tradition of historiography. In this approach, various groups claim they “migrated" from , for example, Yemen, Iraq, Egypt or Mecca, perhaps as a result of the prestige to be gained by the association. Even Forest peoples such as the Efik, Igbo, Bini and Yoruba, have at one time or the other traced their 3 ancestry to these locations. Like the myths and legends, the factor of the supernatural is very dominant in Islamic historiography. For example, the rise of Islam corresponds to the rise or origin of communities and peoples. In fact, this Islamic rise of people and history, went into decay after the first four caliphs (Roberts 1980:321-326), and individuals within the community of Dar-al-Islam should work back their histories and societies for the restoration of the golden age. Arabic literacy helped to reinforce this ideology. Afigho sees irrationality in Islamic historiography, in that real human factors and genius in different local settings are ignored or undermined. 1.12 WW- Colonial historiography in Nigeria, marked a watershed. For the first time, an integrated account was needed for the purpose of administration. Colonial historiography however introduced its myth, -- the "myth of race". Different Nigerian peoples were seen to be at different levels of history or civilization based on their racial type. This was a "man-centred" historiography, and its racial principle was Just as “irrational" as the supernatural myths of precolonial times. ’It was believed that different races passed through cultural stages, from primitive to complex, advanced or civilized society. Evidence for this was observable in the political ability or "cultural virility" of the light-skin, Hamitic peoples of the northern savanna, 4 compared to the “naked savages" especially prevalent in the forest region (Perham 1937z3). This view was reinforced by the presence of centralized political administration amongst the Islamic peoples of the Sudan. Peoples of the Forest who similarly had centralized political organizations, such as the Yoruba, Benin, Idah, Nri and the "organizers of the long JuJu (Ihini flkpghi) oracle of Arochukwu“ were regarded as being ruled by descendants of "small bands of the Hamites", which penetrated into the forest. Non-centralised peoples, such as the Igbo, Ibibio, and the Benue Plateau peoples, came on the lower end of the racial ladder. Colonial administration applied this principle in the Indirect Rule system, where the centralized peoples were governed through their traditonal rulers, while the non- centralized peoples were administered through locally stationed colonial officers. 1.13 W W- ‘ Post-colonial or “nationalist historiography" presents different facets, and partly reflects the previous colonial definitions of the racial principle. Post-colonial historiography again, introduced its own myths and subjectivity which manifested as ethnic nationalism, in which newly Western educated elites strived to write down the histories of their ethnic groups in such a way as to create the impression of a long standing histories of occupation of their localities. Ethnic historiographers also wanted to show the hegemonic dominance of their groups over others. They also saw the "beauty" or relevance of their traditions or institutions in modern society. In terms of methodology, they relied more on "oral tradition", which includes the myths and legends, folktales and so forth of the precolonial period. (Alagoa 1972). In more recent times some have applied the evidence of Archaeology. (e.g. Onwuejeogwu 1981). The point, however, has remained as to the objectivity of historiographical method. The archaeological and anthropological perspectives can be shown to offer more valid approaches for an objective presentation of history not because methodological and theoretical problems do not exist, but because it is possible to work with competitive and potentially valid assumptions or hypotheses. 1.2 MWW ’ In this section the point is that, archaeological and ethnographic methodologies have been important anthropological approaches to historiography in West Africa. To illustrate this point, some key cultural motifs during the Early and Later Iron Ages in West Africa, are briefly surveyed. An important point made by Shaw (1976:159), in a tribute essay in honour of Basil Davidson, stated that African Archaeology had progressed from a consideration of 6 "What Happened" to the establishment of "How it Happened". The issue here was that an outline, or a framework or chronology had been established for cultural study on the continent. In the case of West Africa however, although far little is known of its Early and Middle Stone Ages, when compared with the rest of the continent, there is good evidence that the subregion was populated at least not later than 10,000 years ago, (McIntosh and McIntosh 1981), by Late Stone Age peoples. From this point on, progressive development transformed the peoples from hunter/gatherers to societies and cultures who practised agriculture and animal husbandry from about 7000 years B.P. Early iron using peoples such as the Nok culture (from about the 8th century B.C.) had settled villages. Through the development of long-distance trading networks, towns centers for the control of trade items and resources developed earlier within the transitional savanna zones. . In Nigeria, the Nok culture complex is a good example of a tradition that was continuous from the Later Stone Age to the Early Iron Age. Nok has been known for its terra cotta art styles and it is dated from about the 8th century B.C. to A.D. 200 (Shaw 1981). Nok culture has been recognized over a wide area of the Middle Belt of Nigeria and it’s cultural influence in art styles and pottery are known from the Later Iron Age societies of Ife and Benin. Another Early Iron Age motif culture complex, comes from 7 the Mauretania-Senegal area of West Africa. This is the construction of funerary megaliths and tumuli. The tumulus is a burial mound, and one for which there is an Arab written record was constructed in A.D. 1067 for the king of the empire of Ghana (McIntosh and McIntosh 1981:612). Megaliths on the other hand are single stone structures erected at burial sites and evidence of such structures indicate a fairly complex caste society. Some archaeological sites associated with these structures include Tegdaoust and Koumbi Saleh, reputed to have been the capital city of ancient Ghana. The site of Tegdaoust in Mauretania has a rich cultural deposit (and may date) from about A.D. 810 to 1800 associated with brick and stone architecture, local and imported ceramics and stone and metal artifacts suggesting trading links, agriculture, smithing, hunting and tailoring (Es’Andah l976:4, Hill 1978:604-605). In later West African societies, Arab and European influences, are particularly important in the development of trading relationship. Some of these relationships can be specifically described as follows: In the context of Arab and Islamic influence from about A.D. 700, West African agricultural productive techniques became mixed with trading or mercantile activities. The long distance trading networks across the Sahara involved the exchange of salt, cloth, and beads for West African gold, ivory, and slaves. Well-known trading centers of this period, include Timbucktu, Gao, and 8 Jenna Jeno in modern Mali; Sokoto, Katsina and Kano in northern Nigeria and perhaps as far south as the forest states of Benin in Nigeria; and Begho in modern Ghana (see Figure 1; Davidson 1974:62; Calvocoressi and David 1979:2). West African currencies included gold, brass, salt and cowrie shells (Cowrie shells were used up to colonial period, and were traded from the Maldive Islands of Sri-Lanka and the coast of East Africa. ) (Johnson 1970:17-49, 1970:331-353). Accompanying this mercantile influence was the use of horses, spears and swords, but the plow, the wheel, and the shaduf (an Egyptian device used along the Nile for drawing water) although penetrated into the Sahara, did not reach West Africa. Agricultural production techniques, therefore, remained simple with the use of the hoe and the slash and burn method. The land use system was also simple; vassalages and the landed fiefs were either absent or very unlike those of feudal Europe. During European contact, the mercantile economy was intensified first by the trans-Atlantic slave trade and later by trade in palm (oil and so forth) produce. European contact brought with it the use of the gun which partly reinforced the powers of coastal or forest kingdoms. Jack Goody’s (1971) ethnographic studies have classified the recent West African societies into types namely: Acephalous societies, mass dynasties of the savanna, and forest kingdoms. The acephalous systems consisted of segmentary groups whose important cultural equipment included ' Kano- o‘\ .v \ ‘1131 1‘ \’ o\’—\ \ \ ‘ ~ , QI/QI/QI/QI/QIa/«Ia (‘0880110 . 1 a, I O \ o \ I I \/ \/ \/ \I.’\’: l— / / anlfl / . \‘\ \~.~. \‘\‘ \‘x \ \ \ I’ I/ l/ l’ I/ I/ I/ I/ o.

The societies lacked centralized government and are sometimes also described as egalitarian. They were present in both the savanna and forest, often living side by side with centralized polities. Such groups include the LoDagaa, ermbe and Bole of Modern Ghana, and the Segou and Kaarta of Mali. The "mass dynasties" on the other hand, were organized around control over trade routes in the Sudan zone. The states depended on a mobile cavalry forces which were sometimes used to raid the ill-equiped infantries of the acephalous peoples. Leadership within this group appear to have rotated within an elite class of Islamic lords. In some states, such as was in the Mossi (Bourkina Fasso), there was control over the production or smithing of spears and swords or other items, symbolic of state power. The centralized kingdoms of the forest, were distinct in that they initially based their powers on mythological sanctions, but they became despotic during the slave trade, from access to guns which they used to raid the hinterland for slaves. 'Such kingdoms included Dahomey, Benin and Opobo (Dike 1956). L3213£22§22£ihi§m It would appear from the brief overview above, that specific cultural determinants are responsible for the growth of society. Such determinants include change in the technoeconomy, militarism, trade and religion. Can some or all of these determinants account for the evolution of the 11 ancient kingdom of Benin, (south-western Nigeria)? What criteria are to be applied to address this problem objectively? In Chapter II, this question is brought more to focus through a critical survey of Benin research and related studies. In Chapter III, this study focuses on the archaeological methodology. CHAPTER II mwmwm 13 In Chapter II, information about Benin is sifted from various study foci that could throw light on the uniqueness of the people, their environment, society and culture. The purpose of this is to provide an understanding of the setting of the archaeological research, review the literature, and to provide interpretive information which will be drawn on in later chapters. Information has been drawn from ecology, society, art, architecture and archaeology. Benin City is located within the high rain forest zone of West Africa. It has two clearly marked rainy and dry seasons which partly regulate the hoe agricultural economy, with root crops as the main-stay. The people speak a language that belongs to the (Kwa subgroup) Niger-Congo branch of the Niger-Kordofanian family (Greenberg 1970). The society is organised in two ways, - a village social organization, on one hand, where age is the criterion of authority, and a town or state social organization, where authority is hereditary and based on the "rule of primogeniture“ (inheritance of first son). The sex.principle cuts across the two, for only males can participate in the two modes of social organization. Historically, the art and architecture more vividly help to illustrate this Benin patriarchy. Previously, Benin 12 l3 archaeology has been addressed mainly to the city center, or to the symbols of the state system. It has also provided a more reliable chronological framework for the tradition. As will be shown, it is possible to provide further evidence for this mode of social organization outside the city center and to demonstrate that this was part of a universal phenomenon. 2-1 3221252.. The unique ecological conditions in the Benin area must have played a significant role in the development of the ancient Benin society as it continues to be important in the area. For example, agriculture is still heavily dependent on seasonal rainfall farming and, traditional builders relied on the red Benin soil for house construction, clay image building and pottery making. (This has however been changed significantly since the introduction of concrete during the colonial period). The red Benin sand or Benin Formation, as it is geologically called, underlies Benin City itself, and a considerable area around it (Figure 2). The Formation is sedimentary, and is of Miocene/Pleistocene in age. It is composed of yellow and white sands with iron stained gritty beds (Freeth 1975:225-228). The Benin Formation probably derived from a northern sandstone deposit, which is of Paleocene to Lower Eocene in age. The oldest sediment in the area, is the crystalline basement complex, whose age ranges from Precambrian to the Lower Paleozoic (Ogunkule g; li g1 1980:1-3). North of Benin City, and in many parts of Nigeria, this basement complex outcrops as many folding inselbergs. The Benin Formation is overlain on the southern coastline by recent beach and alluvium deposits which also include decaying organic swamp materials. Since some materials such as chart and flint, which are alien to the Benin Formation may occasionally occur around Benin City, it may be possible that such stones could come from the sandstone deposit or the basement complex to the north, and reports from the south eastern part of Nigeria indicate, that there are ancient brass or bronze alloy deposits on this sandstone, suggesting it was exploited traditionally for metallic art at some point (Chikwendu and Umeji 1979:155- 161). Geophysically, Benin City land is less than 1.000 feet above sea level, a low-lying plain which is an extension of the coastal plain. The Benin low land rises northwards to the Ishan Plateau, which is the source of most of the rivers and streams of the area. Except for the hills of the Cameroon-Adamawa ranges, on the south eastern edge of Nigeria, there are no major physical barriers to population movement in the country and the larger rivers must have in the past provided communication routes especially under forest conditions (Figure 3). Nigerian vegetation follows annual seasonal patterns of rainfall. Benin City is located within the tropical rainforest, with annual rainfall between 15 1,524 and 2,032 mm (Figure 4). The double maxima rainfall regime, in July and September here, or generally in the south-west of Nigeria, makes it possible to raise two crops of maize and vegetables annually (Udo 1980:11). Between November and March, there may be a marked period of dry season. There is a steady gradient of drier conditions towards the north, and wetter and more humid situation in the coastal swamps. The mangrove and the fresh water swamps of the coastal region, are inhabited largely by such tree species as Bhizgphgzg :gggmgfig, with aerial breathing roots, and the raphia palm, which the people exploit for locally 'brewed gin. In the rainforest, the natural tree cover consists of giant canopy trees such as iroko (thgzgphgzg W) and obeche (W M), which have been exploit for the timber industry. ‘Excessive ancient farming in this area and tree felling now results (in some parts), in a plagioclimax of palm bush (Jones 1956). Evidence for ancient tree felling in West Africa, has recently been related to the beginnings of agriculture in this region which has been dated to 2,800 B.P. (Sowunmi 1985:129). About 100 kilometers north of Benin City, the rainforest gradually gives rise to the savanna, but the practise of bush burning in the region has been influencing the enchroachment of the “derived savanna" ,further south, by the elimination of tender and susceptible plant species, 16 resulting in the spread of typical savanna fire-resistant trees. The land use pattern here is still very traditional. Except in government reserves and plantations, such as the nearby Nigerian Institute for Oil Palm Research (NIFOR), 20 kilometers north-west of Benin City, individuals and family groups own and raise gardens and farmlands to plant seasonal crops and cash crops, or to protect semi-cultivated species such as the oil palm, kola nut and timber. The peasant farmers do not use any particular water or soil controlling techniques but rely on the traditional method of bush fallow and/or shifting cultivation for such arable crops as yam, cassava, and cocoyam. Other crops may include rice, maize and beans. Except for the indigenous guinea yam, most of the other crops are introduced from outside especially since European contact. Introduced cash crops here include cocoa, rubber and coffee, which are also largely in the hands of peasant farmers. Along the rivers and coast, fishing, hunting; and collecting are known. Coastal fishers often exchange their sea and river foods for farm produce from the hinterlands. l7 ’. '8 3' g ' ‘ C ‘ ‘.’ I s . I p I j o s \ a a i \ .§"'. ’8: .‘I 91". \. \".\'O'\I""’ ‘5’ z.)

Edo language belongs to the (Kwa subgroup) Niger-Congo branch of the Niger-Kordofanian family (Greenberg 1970). Sometimes, linguists classify the language into the following (Bradbury 1957:14): I Edo proper and the Ishan and northern Edo dialects. II The Urhobo and Isoko dialects to the south. Traditionally, the people of Edo proper who live mostly in Benin City and around it, refer to themselves and the language they speak as "Edo". They also call the Benin City center as "Edo". In more recent times, the Edo proper has been called Bini, perhaps to distinguish it from other “Edo” dialects. The origin of the people is obscure in myths and legends. Popular Bini myths speak of founding father to have come from the sky, being the youngest son of ngnghgg (the Bini high God or supreme diety). This youngest son also ‘became the first ruler of the Bini people or Edo world, and Ihim and rulers that followed him became known as Ogiso (ruler of or from the sky). The traditional Bini historian, Jacob JEgharevba, puts this Ogiso dynasty as before A.D. 1170. At .at about this time, a practise of maladministration led to cirisis and revolt and the people unable to find a suitable 33 ruler, sent to the ruler of Ila-Ife, to the west, in the Yoruba country, to help provide a ruler (Egharevba 1968:1-8). Oranmiyan, was the ruler that was sent from Ife, but it is his son by a Bini woman, called Eweka I, that is generally regarded as being the first 9b; of Benin (as the rulers came be called.) It is thought that this second period in Bini history, lasted until 1897, when the then oba Ovonranmwen was deposed by a British punitive force and exiled to Calabar (on the south-east corner of Nigeria.). The third period or the most recent, falls into the colonial period and after. Evidence from archaeology more or less corresponds to this chronology. Individuals are grouped politically in Edo society at various levels from family to village or town political units. The nuclear family consisting of a man, his wife or wives and their children (who may own a house or be located in rooms in the house of a man’s father or senior brother), constitute the smallest socio-political unit. There are also "joint family" and extended family groups, usually consisting of a man and his married brother and sons with their wives and children (Bradbury 1957:27-28). Members of the family groups co-operate with each other in economic pursuits as :farming, house construction etc. The head of the localised patrilineage settles disputes and punishes misbehaviour, and as he is often a member of the senior age grade in the 34 . village council, he represents the family and he is responsible for their actions. The support for the authority of the family head, lies in his position relative to the deceased patrilineal ancestors. The "rule of primogeniture" (inheritance of first son) in Benin (Bradbury 1964, 1973), makes this matter a complicated affair, for it is the eldest son who sets up an altar at which to worship and communicate with the deceased father; and his warefare, and that of his siblings, wives, brothers and agnatic descendants is thought to be dependent upon the goodwill of the deceased father and his lineal ancestors who punish wrong doing with sickness, death and other catastrophes. The eldest or senior son thus has access to powerful supernatural sanctions for his authority, but this authority is not complete so long as there are surviving dead fathers junior brothers, who do not have their own altars but have to be represented in that of their senior nephew. The intense conflict that may arise from this vig-g-vis, property and residence, tends to weaken lineage affiliation amongst the Edo people, and descent is rarely traced beyond the extended family group, unless there is the prestige to be gained by belonging to an important title holder. 0n the other hand, the people have a .more "unitary" village social organisation, in which although the “clan" may become dispersed, members of the village see themselves as one and co-operate as such in economic and cultural pursuits (Bradbury 1957:30-31). 35 The pan-village three-tier age grade system cuts across kin groups and makes age rather than lineage affiliation, the criterion of authority. The age grade system consists of lzgghae, consisting of boys in their teens who perform communal task of clearing and cleaning; the lghglg, entered by adult men who perform the heavier skilled communal tasks, as an executive arm of the political organisation; and the Edign, who are exempted from communal labour because of age and who form the village council for political and judicial purposes. There are two kinds of village headman namely: hereditary and non-hereditary. The non- hereditary head of the Egigp grade is called Qgignggrg, found in all villages and age is the principle factor of appointment. Not all villages on the other hand, have an hereditary headman or nggig, who may rule over a number of villages which thus constitute a chiefdom. The "Qgigngggg concerns himself with age-grade organisation and the internal affairs of the village while the Qnggig is the community’s representative vig-g-vis other villages and the central authority of the kingdom" (Bradbury 1957:33). This central authority in Benin City center is generally regarded to be co-terminous with the arrival of the Obaship from Ife, although this is a matter of debate (Obayemi 1976, Ryder 1975 ).

These sites appear to have been abandoned, by the local people, in the early part of this century due to resettlements along newly constructed highways. When reconnaissance surveys were first carried out in the area in 1982, several recently abandoned sites were identified. The sites are presently located in secondary forest plagioclimax of herbs and palm bush. Some of the locations were occupied with recent farm or garden plots, and, unable to sieve through the forest mat, we took advantage of farm clearings to make collections. In some area, where some of the cultural plants are protected, several tree crops could be observed. Also, the characteristic Bini ritual plant called lkhinmig (4), can be seen. A shrub plant, which is evergreen, the people regard ikhinmin as “the oldest tree in the world" (Nevadomsky and Inneh 1983:52). It was planted to establish a new settlement and almost each compound in recent settlements has one or more planted ikhinmin. Ancestral and earth sacrifices and other rituals, such as purification rites and oath taking particularly by women, were often addressed to the foot of this tree. When old settlements were abandoned, the plants were often protected on the spot. Apart from plants, the northwest sites also commonly had wall embarkments, ditches, cisterns, as well as pottery, cowries and other cultural objects. Not all of these can be observed in all the sites. 93 Perhaps, the very ancient sites can only be recognized by relatively few sherds which are characteristically worn. On the basis of these observations, the northwest sites were initially segregated as follows: 1. Sites with worn sherds: These appear to be mostly located north and northwest of the Uwan wall and the NIFOR station. We collapsing house walls or ditch system were observed. (Figure 14). 2. Sites which appear to be contemporary with the Uwan wall. These sites are located mostly within the Uwan wall. They show a high frequency of pottey on the surface, with charcoal and often a humus mound or bill. A reassessment of this in the 1985/86 field-work, indicates that these type of sites are similar to the type 3 sites, and that the chronological relationship of these sites with the Uwan wall needs to be objectively based on absolute dates, before firm conlusion can be reached. 3. These sites (commonly on the south of Uwan Wall) also have a high frequency of pottery, charcoal shells, including humus mounds, series of ditches and walling features. Sometimes, the walls are semi-circular or linear, and they are commonly discontinuous. The excavation programs (5) were based on a number of considerations, including the available funds, facilities, 94 (e.g. equipment, laboratory.) personnel, and available time, on the basis, of which, one living site (Eko Abetu) and the transect through Uwan wall (Uwan Wall site), were excavated. Test trenches were dug on a third site - Evboneka Farm site. This was the first phase.of the field work on the northwest. The second phase fieldwork was under-taken in November of 1986 as has been mentioned. 3.3 Eko Abetu 51:: (Figure 15). This site is situated on a hill crest, about one kilometer north-east of the present Ekiadolor village. Informants claimed that this was the old settlement of Eko Abetu, a village now about two kilometers towards the east. The settlement appeared to have been abandoned in the 1920s, when the people moved to the old Benin/Akure highway, constructed by the colonial administration. This site appear to be on one of the highest points (400 - 500 feet above sea level) in the area of flat to gentle slope topography. Cultural features in the form of coconut palms, mounds, walls and ditches are clearly visible within the site, although the site may not be readily visible as a result of bush cover, from along the Eko Abetu/Ekiadolor road. The site which is located within a citrus farm, was first located on the 17 August 1982, during which, some pottery and other material collections were made on the surface. It is difficult to be certain of the extent of the site, but on the basis of the series of walls or mounds, it seems to fall within about 95 15000 square meters. Some of the mounds or walling features consist of collapsed materials from house or domestic walls. In some other areas, the mounds appear big enough to resemble the territorial or defensive walling banks. Within the site, these features created a contrast between a west side of walls and ditches and an east side of slope and level ground. The east side appear relatively undisturbed. A 10/10 meter grid system was therefore layed out to sample areas of high ground (or mound) and location on the low ground. Numbers were assigned to the site grid as in figure 16 (Joukowsky 1980:130, Fladmark 1978:84). The excavation grids were established in such a way as to cut through one of these walls (see Figure 14, trenches X2 and Y2), 'as well as digging a trench on the relatively undisturbed slope (trench Bl). X2 and Y2 trenches each consisted of a 5/3 meter, while Bl was 4/4. 3.31: IIQEQL 21‘ This is the trench on the east side of the datum, and on the gentle slope that appear relatively undisturbed (see Figure 15). The 4/4 meter trench was positioned to avoid the orange trees and as much as possible their roots. Digging was done in 20 cm. arbitrary spits through 4 levels.(6). A fifth level was dug to half, on the north end of the trench. No features were noticed on this trench, and three distinct layers can be recognized on the profiles (Figure 17,18). The 96 uppermost layer consists of very dark grayish brown humus materials and roots. The materials are generally loose. This is the most recent occupation layer. Layer 2, is of dark reddish material, and fairly more compact sand and clay, but, fewer roots. This layer is also cultural. The third layer is very wet and sticky and perhaps has .more clay components. This layer is largely sterile and corresponds to the Benin Sands. Only level 1 appears to yield bottle glass, a European product (see Table l). 3-32= 1mg}! XL X2 and Y2 trenches were established close to each other to cut across one of the low mounds which (by the presence of a wall stump on Y2), appeared to represent collapse housing features (Figure 15). The trench was dug as in Bl, through about four levels. This trench presented features which would have been harder to read, if Y2 had not been dug. The upper humus layer is represented (see Figure 19 and 20), and this is followed by very hard compact dark collapse materials- This is in turn followed below by very coarse or gritty sands. It was significant that the dark reddish brown (hearth) layer, clearly noticeable in Y2, (see Figure 22, 23). was absent in X2 in spite of the closeness of the trenches. The deposit here, therefore, suggest disturbance, since also pedological studies of northwest deposits (Ogunkunle g; 31 1980:31), indicate a significant increase of 97 clay component to a reduction of coarse sands, below 52 cm. depth. Cultural artifacts from X2, (see Table 2) include European or bottle glass, from levels 1 and 3, and then 2 distictive gun flints (see Plate 1, Figure 21) from level 4. At first, these stone artifacts were thought to be belong to prehistoric period, or the West African Late Stone Age, but experts in historic artifacts (Jim Robertson, Dean Anderson. and Professor Cleland ) of the Department of Anthropology, Michigan State University, confirm that these were gun flints and therefore European products. 3.33: Trench 12... The Y2 trench, appeared to contain more interesting features. A wall stump had been present on the mound surface and this was traced into level 2, where it appeared to have been established on hard concrete-like foundation. (see Figure 22). But the surrounding materials are part of the wall collapse, on top of which is the humus mantle. Below this compact collapse house features is a dark reddish brown, hearth layer which includes several snail shells and charcoal. A carbon 14 date of A.D. 1432 1 100. has been obtained from this component, which appears to be securely sealed below the last building occupation. (specimen sample number: EA/Y2/4). Below the hearth layer, is a red clay layer which appears to corresponds to the Benin Sands. European items are absent from this trench and apart from the 98 pottery, there are 3 fragments of locally made smoking pipes (Figure 35f), and a round polished stone in level 4) 3-4= Emmm The Uwan Wall site was located following the works of Maliphant gt a; (1976), whose mapping indicated similarity between this wall and the 2nd and 3rd walls of Benin City in terms of magnitude, or height. The height of the Uwan wall is between 1 and 6 meters. The height of the wall was probably never quite even and also erosion and weathering activities could have progressively altered it’s height. Informants indicate that this wall acted as demarcation between the chiefdoms of Uwan within the wall and Iyowa to the south of it. At the wall, excavation strategy was to cut a transect across the wall essentially to obtain dating materials to provide chronological information between the relationship of the wall and living sites within and outside of the wall. The wall was encountered at the Evhoneka village, on it’s southwest (Figure 14), from where it was traced towards the east. A point was established within a rubber plantation in an area which was fairly open and where the wall was not too high (see Plate 2, 3). A grid system was layed out from a datum and a 10/2 meter excavation grid was layed on the Uwan wall as the Uwan Wall Trench (UWT. Figure 24). Two test trenches (TT) were also established on both north and south of the UWT. The site slopes markedly, 99 and the slope becomes very steep towards the south, in the direction of the new Benin/Akure highway. Excavation on the wall was done in steps (Figure 25). On the sloping face of the wall, the deposit is quite disturbed and drifting. The deposit appears sterile, with only occasional (small fragments of ) charcoal turning up. (Connah 1975 :85). A few charcoal specimens have been obtained for dating (from layers which appear more stable and not too close to the surface.) The test trenches also turned out to he sterile, apart from a few pottery fragments and some charcoal. 3.5: mmm Far less time was spent on this site than would have been necessary due to time constraints and the limited nature of funding. The site was located for the first time on 4 April, 1986, through informants who said the old Evboneka village site was located towards the west. The site turned out to be situated within recent maize and cassava farms, and also close to the Uwan wall on it’s inner side (Figure 14). Only 4 pottery sherds were located on the surface in spite of much searching. For two days, two trenches, one 5/3 and the other 2/2 meters, were tested. The 5/3 trench turned up 22 shards and a few stones through a depth of 40 cm. The sherd ‘consisted of 2 rims and 20 very small body fragments. 100 3.6 Seams In summary, one habitation site outside the Uwan Wall and a transect across the Uwan wall have been excavated. A third site within the Uwan wall was tested. Cultural features and artifacts have been recovered. It would appear from a general point of view and based on the excavation alone, that at least 2 occupation deposits or phases are represented on the Eko Abetu site. There could be more, but such a decision would have to be based on further analysis of the artifacts. 101 w m 8 e. .a a a _ nutmeg. mum one pm. a» .a a. n a... wag-fl in”... “85. 8.... 2.“.

In spite of efforts, only the Eko Abetu site yielded any good analytic materials from the first phase of excavation on the northwest. There were therefore no comparative artifacts from a different site. The excavation program of November 1986 on the northwest was designed essentially: 1. to look for and excavate a living site that could offer a relatively abundant pottery sample. 2. to compare the new materials with those of Eko Abetu and to see if a spatial relationship exist between the sites. 3. to collect more dating samples. 4-1 Eran Liziaa Site (Figure 26). This site was first located on 30 August 1982, and it was excavated between November 22 and 29, 1986. The site is located off the Benin/Akure road, opposite the present Uwan/Ogbogiobo villages (Figure 14-D). In November of 1986, the old' farm plots where we made collections in 1982, had been over-grown with weeds (7). We therefore entered a cocoa plantation within the general area of the site to look for a more open space which was convenient for laying the 104 105 excavation grids. Uwan village is mentioned by Egharevba (l968:3) as one of the oldest Benin villages to have been founded in the lat period (before 1170) of the Benin history, but Chief Ogiezughanmen, the owner of the cocoa plantation explained that Uwan and Ogbogiobo villages which are now almost merged together, were founded at about the same time during the reign of Oba Ewuare (about 1440). The founders were members of the Benin royal family. Ogbogiobo village has remained more or less on the same spot, but the Uwan village had moved closer to it’s sister Ogbogiobo when the motor high-way was constucted in the early part of the century. Chief Ogiezughanmen explained that the presently abandoned Uwan settlement was very extensive, but not as big as the present village. The size of the ancient settlement is difficult to determine on the ground because of the dense vegetation, but judging by the mounds and sherd scatter, on the plantation and the farm plots, one could estimate that the village must have been about 250,000 square meters in area. The site map (Figure 26) illustrates that like other northwest sites, mounds and ditches are present and the areas are often associated with farm plots based on shifting cultivation. The Uwan Living site is located on high ground about 500 feet above sea level. (The lowest ground areas here are about 200 feet above sea level. Such areas are close to river channels). The site is about 2 kilometers northwest of 106 the present Uwan/Ogbogiobo villages. The excavation grids were established as shown on the site map (Figure 26). A 2 by 7 meter trench (410) was established inside the cocoa plantation, and a 4/4 meter (420) trench was established just outside the plantation, open enough to avoid the cassava crops recently under cultivation. The owner of the site showed us some iron slag from ground surface close to trench. 420. As usual, excavations were done in 20 cm spits. The materials were not seived but efforts were made by probing with a trowel to reduce the chance of losing some cultural materials. (6). 4.11 Imm= This trench was established on a low mound top. On its south end, the deposit is quite disturbed with evidence of two or more pits. These pits were traced to level 3. On the whole, the materials are loose with coarse sand and humic materials (dark grey on top, turning to red below). In levels 2 and 4, on the northern end, the deposit is more consolidated or compact. Isolated bricks occur now and then and levels 1 to 3 revealed an adequate sample of pottery. (see Figure 27, 28, Table 4 . also see Plate 4). 4.12 Trench $29: This trench contrasted with 410 in that the deposit is hard. It is on a lower ground and could have been affected by erosion and other weathering factors leading to lateritic 107 concretion. This reddish laterite was present throughout the deposit appearing to mask the layers. In level 4, and on the south east end, there is a lens of charcoal/hearth material. Even though the level itself is largely sterile, this lens contains numerous pottery sherds. The trench in general also yielded a good pottery sample (Figure 29, 30, Table 5 ). 108 ml'l spatusnuu .eoose aspen ovum ocu>de as): new museum messaging!» PAS— eguo couusbsesm § ‘ E O. a, m .ssrswa: roc onsx<\cucom on 3 scausucsao soooo o": 109 o yum cm}: .oumm who: .oHeuOum adv nucoue new museum .53.. ea.— »03 mesa-So a ens. as.— too 026.: £320." ens: V\\\ 58.5 .3195 dosage—:3 + uses: 0-09. + .333 % 110 1m;;f”;rf . . .fi;;‘;‘-; Litter + loose humus + ssnd+roots.

Although, the analytic approaches have been segregated into two chapters, one exploring temporal significance and the other spatial significance, this is done for practical purposes. The idea is to discover variability or the lack of it. In Chapter VII, artifact variability is related to specific behavior modes, based on the assumptions proposed in Chapter III. 5.1 WWW. Traditionally, Benin pottery was hand made, as was the general process in West Africa. (Thomas 1910b, Nicholson 1929, Tremearne 1910:103, David and Henning 1972). There were two most important pottery villages near Benin namely, Use, (now within Benin urban), and Utekon to the north of Benin City, and east of the northwest sites (Bradbury 1957, Willet and Connah 1969. see Figure 7). The potters obtained very finely grained clay from Ekiadolor or Iwu villages towards the west or near the Ovia river. The grayish clay imposed very finely grained fabric on Benin pots. The clay was processed by mixing with water. A new pot was built from 115 116 this. The potters started with a mould, usually an old pot or calabash and by turning this around with one hand and moulding with the other, the desired form was obtained. This was allowed to set or dry for a while before the shoulder, rim and ledge or carination might be added. The potter later smoothened or burnished the pot surface with a snail or coconut shell to reinforce the rigidity and imperviousness of the pot. Various decorative motifs ( e.g. roulette, comb, and groove) may then be applied, before the pots were subjected to intense firing usually in a burn-fire of logs. Pottery materials collected from the Benin northwest reflect some of these patterns. From the northwest of Benin, 2063 pottery sherds from the trenches (B1, X2 and Y2) on the Eko Abetu site were sorted and analysed. The sherds were coded according to the trench and levels as follows: Trench B1 (110) level 1 - 111 2 - 112 3 - 113 Trench X2 (120) level 1 - 121 2 - 122 3 - 123 4 - 124 117 Trench Y2 (130) level 1 - 131 2 - 132 3 - 133 4 - 134 Two major levels of analysis were applied, namely, quantitative and qualitative analysis. 5.2 anntitgtive Analysis. The quantitative method relies on the ability to define an attribute list which reflects morphological and stylistic variables, within an assemblage (Krieger 1944, Rouse 1960, Gifford 1960, Deetz 1965, Brashler 1978), and to be able to transform frequencies of occurrence with a mathematical procedure. There is much debate about the quantitative approach, regarding applicability and context, but the studies of Read (1982:72-73) provide confidence that an attribute definition is a qualitative operation but once defined, it may be manipulated quantitatively. That is, that criteria are really dependent on the problem at hand, and should be formally defined. The northwest pottery sherds were treated as analytic units from which both metric and nominal variables were extracted. Analysis has been addressed separately to the rim and decorated body sherds. 118 5.21: Rim Sherdg By an inspection of the rim sherds and on the basis of previous knowledge, the following nominal variables were defined for rim analysis. 3.1.1; mum 14.1.4.1: Flat lip Round lip Grooved lip Smoothened interior Smoothened exterior Everted rim Hatched decoration Carinated interior Carinated exterior Grooved decoration Incised Stab and drag slashed decoration Comb stamping Carved wooden roulette Twisted cord roulette Punctation Wavy-line Perforation 119 More than one variable can occur on a particular sherd and each variable is scored presence/absence. Secondly, no distinction is made at this level between pot and bowl, since this may be subjective, but commonly, everted rims come from pots although the inward slanting rim of a shouldered bowl (see Figure 42F) can be confused for a pot, using this criterion. Thirdly, it is the technique of application of a variable that is considered more important here than the tool of application. For example, punctate decoration could have been done with different kinds of tools and it would be nearly impossible to determine the particular kind of tool involved. However, carved wooden roulette (because of the sometimes angular or regular nature of the lines) and the twisted cord roulette (because of it’s bead pattern), cannot be missed in an assemblage. Stab and drag appears as a particularly variable form. On the rim ledge, stab and drag appears to be applied with a pointed blunt object. On the body of some sherds, it is sometimes applied with a comb. No case was encountered where two kinds of stab and drag appeared on the same sherd however, and such would have introduced a problem. But there were cases where the variable called "slashed" occurred with stab and drag particularly along the raised ridges of the rim. The slashed decoration appears to be a successive horizontal movement of the hand, as if trimming the raised ridges. 120 Some of these decorative motifs have been illustrated in the photographs (see Plates 5 - 9). The Plate labels are as follows: Plate: 111 body sherds 121 rim sherds 5 6 7 - 132 rim sherds 8 132 body sherds 9 133 rim sherds Some key or essential attributes have been marked on the photographs as follows: a : carved wood roulette b : punctation c : slashed d : grooved e : wavy-line f : twisted cord One point of note is the variation that exist even within the units, The carved wood for example, may consist of vertical lines associated with polygonal patterns, zigzag or diagonal lines. The stab and drag pattern does not come out clearly in the photograph, but is commonly located on the lower ridges that run on top of the in-curving rims of some bowls. On the higher ridge as in in Plate 6c, is the "slashed" pattern. (also see Figure 32 for schematic illustration of the decorative patterns) 121 Rim Nominal Scores, Trench Bl, Eko Abetu TABLE 6 * O .3 5‘ ~- _-.

"a" represents co-joint presences, and it is expressed as a proportion of the sum of all presences, ignoring co-joint absences. Jaccard’s coefficient lies between 0 and 1, (Doran and Hodson 1975:140- 142), where the lower end of the scale expresses maximum dissimilarity, while 1 indicates maximum similarity. Jaccard matrix is presented in Table 9 and this is clustered by the average linkage method(10) (see Figure 31). The cluster shows a clear distinction between the lower levels and the upper levels of the trenches (which appear to cluster on opposite poles), confirming the basic nature of the excavation deposits. Beyond this, very few other inferences could be drawn at this point. The T-test, a powerful test for interval scale variables approaches normal distribution for large samples and corrects for the bias in the deviation of small samples.(1l) The Null hypothesis for the paired comparison of sample means is set to determine (a) Ho: that differences 152 between means, due to chance and (b) Hi: that differences between sample means are not due to chance, or that there is significant patterning in the materials under observation. The t-test formula for the estimation of mean differences is given by: GE.- fz) - (m- )21) t = .1. [5" + s: n: “z where i represents sample mean ,D population mean S2 "pooled estimate“ of variance between means. n number of values in a sample. S = Lx.- 2}) + (33' 3&2 n. + 112+ where: n\+ n1+ 2 = degrees of freedom (df) In the t-test formula above, the Ho Null assumption has it that population means are equal or that,fl = ,D, such that the formula becomes (§:“§i) ’ 0 Sf + _§; .3: n; The alternative hypothesis (Hi) is that‘p f ,H T-test determinations which are presented in tables 10 and 11, show significant patterning between the pairs of 111/123, 112/123, 112/132, when alpha level is set at 0.01 (two- tailed). 153 Although, no distinction was made between pot and bowl rims in the t-test determinations, there seems to be a general tendency for earlier or older materials to be thicker and more crudely made. Age therefore, could partly account for these differences. This should not also preclude acitivity variations of a spatial character, that may have required the discrimination between one kind of pot and another. In some of the levels, as would be presented later, there is sometimes a marked differential frequency between pot and bowl vessels. 5.22WMM For the analysis of the decorated body sherds, a separate attribute list was segmented from the one already used for rims, as follows: WMMWMM- Grooved Incised Wavy-line Carved wooden roulette Twisted cord roulette Stab/drag Punctation. This attribute list was decided upon for convenience and the fact that though a great deal of variation may occur within such groups as stab and drag, and punctation, these 154 variations could not be objectively isolated. The issue of the stab and drag has been mentioned in connection with rim attributes, and as would be seen in table for attribute frequencies of decorated body sherds (Table 12 - 14), stab and drag decoration is minimal on the body of pots. Punctation on the other hand is widely applied to the body of pots, and bowls, particularly towards the basal portions. The impression sometimes appear circular, lunates, oval, dotted etc. (Plate 5 - 9). What is common in all however, is that even though they may appear singly, or in groups, they appear to have been done with a single tool as distinct from punctates done with a comb for example. There was no particular case however, where there was doubt as to whether the punctate was done with a single tool or a comb. Comb appears to be absent. If such a case had existed,. it would have probably been more convenient to group them together since the idea of punctation is the same. But when a comb is used for stab and drag, the idea is different. The point does not contradict the difference between grooved/incised and carved wooden roulette/twisted cord roulette for example. Carved wooden roulette and twisted cord roulette can be conceptually separated. As was indicated by informants in 1982, at the Use pottery village near Benin, women potters cannot make the carved wood themselves. It requires special skill akin to stone tool making, to be able to carve the patterns on the wooden object (12). Only men 155 have this skill and this is an example of a point at which male contribution to the pottery process can be recognized on the pot. Women could make the twisted cord by themselves, since women were often better at plaiting fibres together. Yet, within these decorative techniques, there is a great deal of variation, depending on the kind of fibre and the particular inclination of the wood carver for example (see Plates 5-9). The point of convenience as made above, is related to the method that was to be adopted for the transformation of the nominal scores arising from these attributes. The X2 statistic was decided upon. It is simple and convenient, but become "cumbersome as the number of variables increases" (Doran and Hodson 1975:55). Like the t-test, the chi-square provide a method by which relationships or the lack of it 'between variables can be judged with some degree of confidence, following the works of Spaulding (1953). And like the t-test, the chi-square has been applied to the components from the excavation levels which are treated as units. As a non-parametric determination, the chi-square statistic does not assume like the t-test statistic, a normal population distribution to which the sample mean may fit.(13) 156 The chi-square statistic is given by the following convention: 2 x2 =£(o - E) E or, the sum of observed frequency (0), minus the Expected frequency (E), squared, divided by the Expected (E). Comparing each level with every other level, at the Eko Abetu site, a total of 55 chi-squares were computed as is shown in table 15, with chi-square critical set at 0.05. Degres of Freedom (df), is given by (row - l)(column - l). The result turns out to be very interesting and can be summarized as follows: 1. Trench B1 levels show marked disagreement between each other, partly suggesting a well stratified sequence. One can therefore say with some degree of confidence that the Bl levels are chronologically ordered and that this may relate to distinct historical formations. This agrees with the excavation information. 2. Across the X2 levels, there is no significant difference between the components. The near-by trench Y2 however, does show some significant disagreement between 131/132, 132/134 133/134. These two trenches as was revealed above are located within an area where building processes may have led to the disturbance of the deposits. This is probably what is reflected in the chi-square determinations. The 157 identification of the floor levels in trench Y2 and the fact that these appear to securely seal a rubbish or hearth provenance within level 3 below, appear to indicate that disturbance across the levels was only partial in Y2. X2, therefore appears to have been more disturbed. The markedly large sample of level 132 could also partly explain the differences involving 132. Between trenches X2 and Y2, differences between the levels are at best sporadic related in general to disturbance, a more stratified sequence in Y2 and the large level 132 sample. 3. Levels 112 and 113 do not appear to go with each other and with every other level in the site except with a few exceptions, namely: 112/121, 112/122, 112/124 and 113/124. Given the disturbance in X2, one could yet say with confidence that the two lower levels of trench B1 are markedly different from the upper level of B1 and the upper and lower levels of X2 and Y2. 4. Level 111 does show agreement (with some exceptions) with X2 and Y2 levels. This could mean that the last occupation (building phase of Y2 and X2 or the upper levels ) is contemporary, or at least more closely related to 111 and that relationship between 111 and the lower levels of X2 and Y2 could have been indirect through disturbance or other sample characteristics. 158 5. These correlations, therefore suggest at least three occupation phases for Eko Abetu. An earlier phase represented by the lower levels (3 and 4) of X2 and Y2. The fact that levels 112 and 113 (together), do not agree with this early occupation, and the later and more recent levels, suggests a historical displacement of activities from X2 and Y2 to B1 location, during the deposition of 113 and 112. This ordered sequence has been graphically represented as in figure 33. Some questions would however be raised as to the way in which this result would be affected had the bowl and pot rims been treated separately. The materials have therefore been sorted in a qualitative way addressed to a formal analysis. 53mm It was necessary to produce a general outline .of the pottery forms and types from the northwest which can be used for comparative purposes. Cross sections of the diagnostic rim sherds have therefore been illustrated in figures 34 to 41. The pottery forms have been group into 8 types as follows : (see Figure 42). Ing A: Represented generally by everted rim sherds (Figure 34f; 35e, i, m, 0; 36a, c; 38a, b, e; 39b, c, J; 41a, c, k, m, o, p). Variation in this form relates to size (height, volume etc) and the nature of the everted rim. Sometimes, the evertion may be very slight or the rim itself may be 159 slight or very angular and a tendency to an expanded or more voluminous body (Figure 39a) (Connah 1975 :122-124). This type, reconstructed in figure 42A is commonly decorated with twisted cord roulette followed by carved wooden roulette, below which may be various forms of punctation. The lip may have grooving. From personal knowledge, this type was used as a water pot for storage until recently. Ing 3: Only one sherd of this type occurred in the sample, (Figure 41i), and cannot be mistaken because of it’s long and narrow neck. The form probably looked like figure 42B and may have served as a handy flask for taking water to the farm. No decoration is present on the lone rim. Ing 9: This is a ledge bowl. It is for general purpose, with a ledge, carination or ridge around it’s greatest circumference. The height of the ledge may be much varied, associated with grooved patterns, stab/drag and slashed decorations (Figures 34g, r, u, w; 41f, h, e). see Figure 420, The rims are uncurving or constricted. Ing D: The type resembles type C and it is also general purpose bowl. It may contrast with type C because of a low ridge which may be very reduced or absent. The pot generally looks smoother or more refined (Figures 34a, g, h, l, m, o; 35c, h, j, k; 40b; 41b) Figure 42D, 160 Ing E: This is a popular grooved bowl, and may be very large or deep for storage or general purposes. This may also be called a hemispherical bowl. (Figure 341, n, t, w, x; 35q, v, d; 40a; 411, q, r). see Figure 42E. 1229 E: This is a shouldered bowl for cooking soup. Connah (1975 :117-118) reports that this type also used to be placed in the bottom of house walls as foundation deposits. The bowls are also commonly used in shrines. The bowl features a sharp or angular shoulder, from where the rim leans inwards (Figure 42F). Unless care is taken, the rim may be confused for a necked pot (Figure 34b, c; 41d). Ing Q: A globular little bowl, with a generally smooth curvature and slightly constricted mouth. This was a secure dish for picking seeds and grains by the women and also used for washing the hands or even for serving food (Figure 34p; 35u; 36f, g; 41f) (also see Figure 426). No decoration was observed. 122: E: This is a coarse flat rimmed heavy bowl, which is probably very ancient. Connah (1975 :117), reports three possible uses for it: For washing hands; as a lamp container on the shrine of the god of medicine; and as container for wax by brass casters. (Figure 35n; 39a, 1) (also see Figure 423). No decoration was observed. 161 The vessel count from these types have been scored in table 16. The following points emerge from the frequencies of the types in the levels: 1. The thick walled type B vessels appear in level 3 of X2 and level 2 of B1, which may indicate more archaic occupation of these levels. In the Benin City center, this vessel has also been recognized as an archaic form (Connah 1975 :117, 196. Form F6). 2. Type A water pot is almost absent in 111. Pct/bowl ratio for this level is .09. On the other hand, the frequency of pot/bowl in 123 is comparatively high (2.33), and less so in 112, where pot/bowl ratio is 1.20. The remaining levels show a generally lower pot/bowl ratio. The ratio of .09 in level 111 is markedly low. The sample could be a problem in general, but since the use of these pots are sometimes differentiated, activity differences may be suggested. However, in association with stratigraphic information, statistical results, and design attributes on pottery, presented above, there is a clear distinction between the upper and lower levels of trenches X2 and Y2, and the way they relate to levels in trench Bl. 162 5-4 Dalian The following date was recieved from BETA ANALYTIC INC.

Specimen EA/Y2/4 consists of charcoal from the Hearth material on top of level 4 of trench Y2, Eko Abetu site. The above date was supplied with the following information: the charcoal was pretreated by first picking out any rootlets, and then given our series of acid- alkali-acid soakings to eliminate carbonates and humic acid. The following benzene synthesis and counting of the radio-carbon activity with a liquid scintillation spectrometer proceeded normally. Although one should not put too much weight on a single date, it however reinforces the correlation results of the excavation levels which suggest 3 phases of occupation of the Eko Abetu site. A date of 500 years ago could mean that a 100 year time period could represent a phase of occupation, and this is probably consistent with the cycle of birth and decay of mud wall villages in the forest region of West Africa. Also, the date is quite comparable to dates from occupation sites in the Benin City center (see chapter II). 163 5.5 Summary. 1. The Eko Abetu pottery has been analysed from both the quantitative and qualitative designs. 2. . The correlation of T-test comparisons of rim thicknesses between excavation levels; cluster of Jaccard matrix, chi-square determinations, carbon 14 date, stratigraphy, and pottery typology has allowed this study to suggest three occupation phases for the Eko Abetu site - an early occupation of crude pottery; a distinct upper levels of most recent occupation, associated with house construction; and in between which, is a middle phase occupation, with materials which do not appear to go either with the lower or upper phase. CHAPTER VI CLASSIEICATION AND ANALYSIS g Spatial significance 9.: We we t P_____Lotter - In this chapter, analysis is addressed largely to the pottery recovered from the second phase of excavation from the Benin northwest.(8) At the Uwan site, a total of 2842 sherds were recovered from two trenches. As was done in Chapter V, for the Eko Abetu pottery, the Uwan materials have been analysed both quantitatively and qualitatively. As will be shown, the major result of the analysis reveals that there is a high degree of variability in the northwest Benin pottery. This variability has both temporal and spatial significance. 6-1 WM Qualitative analysis was initially addressed to the isolation of pot forms, and types from the Uwan excavation. What was immediately apparent even from the excavation, was that the mateials were quite different from the Eko Abetu types. In particular, pottery from the trench 420 was distinctively crude or coarse, lacking the surface finish or smoothening of the Eko Abetu forms. At first, it was suspected that the crude appearance was due to the lateritic weathering of the deposit, but the form and decoration analysis showed clearly that other factors could have been responsible. 164 165 Cross secions of the diagnostic forms have been illustrated in figures 43 to 50, These forms have been grouped into types (see Table 17). There are distinctively three new types but some types are shared with the Eko Abetu site (see Table 14 and Figure 42). The new types include the coarse pot (I), flared rim bowl (J), and the short neck bowl (K) (also see Figure 51). These forms or types and some decorative attributes they contain have been further illustrated in the photograph plates as follows: Plate 10 Level 411 rims 11 412 rims 12 413 rims 13 414 rims 14 421 rims 15 422 rims 16 423 rims 17 424 rims 18 411 body 19 421 body 20 424 body. Some decorations have been labelled on the plates as follows: Decoration: a. carved roulette b. stab/drag c. frond impressed. 166 The new types can be described as follows: 122; 1: This is a commonly grooved lip, and thick walled coarse pot. It is most prevalent in trench 420. This pot is similar to type A of Eko Abetu, in general form, but is so different in its roughened surface, thick wall and often grooved lip (see Figure 511). Ing Q: This is the flared-rim bowl, characterised by a pronounced rim hanging over a small body (Connah 1975 :118, and 128). (The type is illustrated in Plate 11, Figure 44, 46, 49). Connah reports that this bowl was used for washing the hands or eating or also sometimes used to cover "medicine", when this is set in a hole on the ground within the house compound. This pot form, which has an external ridge below the rim was not encountered in the Eko Abetu site. Ing K: This is the short neck bowl. Type K neck and rim are characteristically slight or reduced, almost in opposite form to the Type J rim. It is illustrated in figure 44K, Plate 12 and figure 51K. Materials scored into types D and E (see Table 17) were quite varied particularly with respect to rim shape (e.g. the ridges, carination or grooving). E, which is the hemishperical bowl, was however distinguished from D by the larger depth of E. At the Uwan site, both appear to have 167 rims that are incurving. Many of the type E also have straight rims characteristic of the deep hemispherical bowls in the Eko Abetu site (see Chapter V). On the whole however, one could see that the pots from the Uwan site show marked differentiation from the Eko Abetu site (about 8 kilometers away). The type frequencies scored in table 17 were further analysed into pot/bowl ratio which reveal as in the Eko Abetu case, (see table 14), that there is a general tendency for bowl forms to be better represented than the pot. Bowls have far more domesitc use than pots in cooking, serving, washing etc. Where pots show a higher frequency such as in level 414 and 422, for example, it must be explained by an alteration in behavior or some kind of localised activity. Pots were commonly used for storage (water, seeds etc) or for "heavy duty" cooking (such as cooking yams or oil palm seeds). Such activities may at times be communal such as during house building or early farming activities or also during festivals. The mode of deposition of refuse can also partly account for higher pot/bowl differentiation. With respect to decoration, however, there is a general similarity between the Uwan and Eko Abetu sites. The decorations of grooving, incision (often with comb), stab/drag, twisted cord roulette, punctation, are present. This does not preclude proportional differences. Some of these decorations have been ilustrated in Plates 10 to 20, 168 (also see Figure 32 for schematic representation of decorative techniques). One key difference however, concerns the presence of the decoration that has been described as frond impressed. (15). This decoration sometimes looks like large twisted cord patterns, but apart from it being rather large, when compared with twisted cord, one could notice striations in the impressions. These striations are the negative impressions of palm frond veins (see Plate 18-20 c), This is probably what some other workers have described as coarse string roulette. (Darling 1984:223). This decoration was absent in the Eko Abetu site and it’s presence at the Uwan site is a major difference because of its frequency. Some other decorative motifs have been illustrated in the Plates. The stab/drag for example, which did not come out very well in the Eko Abetu photographs can be observed in Plates 10-17 "b“ (The "slashed" form of Eko Abetu appears absent here).

Each attribute present on each sherd was scored 1, level by level, and tables 18 and 19 show the frequency of attributes for trenches 410 and 420 respectively . This data 196 was transformed with the Jaccard coefficient (see Chapter V). As a form of control, materials from the trenches 410 and 420 were compared with one another and with materials from trench B1 ~of the Eko Abetu site. Bl, from Eko Abetu was chosen because it has the best stratified sequence. Jaccard coefficients are scored in table 20 and this result was again clustered by the average cluster method. (see Figure 52), The result is quite remarkable in that materials from each trench essentially cluster separately. In a sense, this reflects what was ordinarily visible (i.e. differentiation). Apart from the demonstration of this differentiation, it is important to explain why it exists. Is this differentiation due to temporal or spatial factors? Which is the older part of the chain? These are difficult questions to conclusively answer. An absolute date would help matters here but comparing the vessel forms on tables 14 and 17, from the Eko Abetu and Uwan sites respectively, one could say that pottery forms from trench 410 are more similar to those of Eko Abetu. For example, type C bowl with pronounced external ridges or carination is absent from the 420 trench but fairly represented in trench 410 of Uwan and the Eko Abetu site. Even some materials from trench 410 have surface smoothening like the Eko Abetu pottery, but unlike the coarse forms from trench 420. This is suggestive that trench 410 deposit may be younger than 420. (note that the Eko Abetu time sequence is fairly well established). 197 However, apart from this time dilemma, the differentiation shown by the northwest materials has other cultural or behavioral implications. It could reflect behavior addressed to localised points. This point is reinforced below by the statistical test results on body decoration. The second qantitative analysis was performed on the data for body decorative scores from the trenches (see Tables 21 and 22). The body decorative attributes are as follows: Grooved decoration Incised stab/drag Carved roulette Twisted cord roulette Punctation Frond impressed Wavy-lines. As with the Eko Abetu materials, the data was transformed with the chi-square statistic, and with alpha set at 0.05 (see Table 23). Out of the chi-square statistics computed for 28 pairs of comparison of the excavated levels, only 7 results show significant similartity. The rest show significant dissimilarity. This result further illustrates the general high level of variability in the northwest of Benin pottery. 198 Looking at the pottery density on the whole, further- more, one sees that the sites may have also supported varying degrees of activities in the past. In tables 24 to 28, the pottery sherds are compared with their weights on one hand, and weight of sherd is compared with unit volume of space on the other. Fragmentation could partly account for the weight per sherd, which says very little culturally, but in the case of weight of sherd per unit volume, the results reflect a general tendency for high weight index as one goes up the levels. This higher index could suggest higher intensity of occupation, the growth of local population, or possibly other unknown factors. When put together, these results indicate a changing pattern of papulation, characteristic of growth, as well as a general mobility of perhaps a segment of the population associated with pottery making. One is however not able to say whether the growth pattern in population may have been dramatic as in migration for example. Will... W191! In Chapter VII, the biases in methodology and analysis are initially identified so as to isolate the strengths and weaknesses of the results. In spite of some inevitable problems, the point is made that corroborative evidence from different ~ angles allow the investigator to suggest interpretive models for the results. This is done by relating specific results and other evidence to the five assumptions proposed in Chapter III. 7-1 Bias The following set of biases can be identified in the methodology and analysis of the northwest artifacts. 7.11 shamanism As has been pointed out, the northwest was decided upon for this research on the basis of previous work in the area and the existence of a base map (see Figure 14). Secondly, the choice of particular site location such as Eko Abetu and Uwan Living site was based on the reconnaissance survey of 1982. The surveys were carried out by methods that might be considered as subjective. Regional survey data on archaeological sites do not exist in the area. Sites were identified on the basis of information provided by local informants, walking through farm paths and clearings and 199 200 the presence of cultural features and artifacts. This was the most practical approach, but it is informative to indicate that methods can be applied which seek to sample and identify sites objectively, both on a regional basis and for within site decisions. More objective probabilistic methods have been applied to wooded conditions (e.g. Lovis 1978) that are of potential interest to tropical forest environments.. Also, surface distribution of artifacts can be objectively related to subsurface materials through the systematic intensive surface collection method (Redman and Watson 1970) 7.12 WWMW This is a recurrent problem in archaeological methodology. That is, how much an archaeological sample represents the archaeological population. It is assumed in this study, that the assemblage samples represent their respective populations. This is not necessarily correct. Depending on the complexity of the cultural environment under consideration, specific sampling strategies (probabilistic in nature) can reduce or eliminate skewness in the bias related to representativeness of archaeological sample. (Also see Lovis 1976). Titiwmxatigndsmif This problem has already been partly answered by saying that by the experience of the investigator in working on comparable sites in Nigeria, it was considered appropriate to 201 probe carefully with a trowel. This method would have been sensitive enough to the mainly expected pottery artifacts. It can also be added that practical considerations of time, money and personnel were in general, constraining factors. 7.14 wmmmdnmm. Arbitrary excavation levels were dug as much as possible following the shape of the ground surface. Mixture of materials between the natural layers was however an expectation, since arbitrary levels may not necessarily follow the natural profile. The role of analysis is partly to identify this kind of bias or correct for it. For example, in the Eko Abetu site, although technically, 11 arbitrary levels were dug in the 3 trenches, the 11 levels were correlated into 3, based on several analytic deductions e.g. the stratigraphy, chi-square results, t-test, Jaccard coefficient, carbon 14 date and vessel typology. Even disturbance by previous artificial processes can be detected in an analysis. Notice for example that the disturbance of pits in the trench 410 of Uwan site, (which were identified in the first 3 excavations levels) is clearly expressed in the chi-square results. Chi-square results for levels 411/412, 411/413 and 412/413, all show significant similarity. If the investigator did not have the independent stratigraphic information, other explanations (e.g. function or persistence) for the significant patterning of the levels 202 might have been suggested. The point however, is that the arbitrary levels were not treated in isolation. 7.15 Over-representation of attribute units There can be low or over representation of artifact or attribute units within a sample or an assemblage. An example of over-representation is a condition where a' large pot breaks into several small sherds. It’s design attributes would then tend to be over-represented (Shapiro 1984:700- 701), especially when sherds are the units of analysis as has been done in this study. This bias could be corrected by working with percentages. Then, the mathematical transformations the investigator has carried out on nominal data may not be applicable, but since this problem could be assumed to exist across the levels, it could be ignored, as the investigator has done in this research. 7.16 Vessel count In establishing the vessel count in an assemblage, this invesigator usually wanted to establish the minimum vessels based on the diagnostic rim sherds. Sherds that were too small were discarded, but there could be a tendency to pay more attention to small sherds in a small sample and ignore similar sherds in a large sample. Attempts were made to avoid this bias in the study. 203 7.17 Begsgnal bigg Personal bias can occur due to differences in judgement. Also, bias of judgement can occur when certain distinct attributes also appear to exist in a continuum. An example of this is related to the frond roulette decoration, which may merely look like large twisted cord roulettes. 'In this study, the investigator was fairly confident that frond impressed apart from a coarse or large nature, tend also to have the negative impression of palm frond veins on them. In general, efforts were made to avoid personal bias. 7.2 Interpretigg uodelg In spite of the difficulties and inevitable bias in this research, results and existing evidence on Benin can be related (to some extent) to the assumptions proposed in Chapter III. 7.21 Assumption 1; Associations between artifact types or design attributes on artifacts can reflect temporal or historical significance. In relation to this assumptions, stratigraphic evidence alone shows that in both the Eko Abetu and Uwan living sites, two distinct cultural deposits are commonly represented over a depth of about 1 meter. Some of the trenches show a third mantle of humus layer more than others. Except in trenches where disturbance create artificial mixture, such as trench X2 of Eko Abetu and 410 of Uwan, the two cultural deposits clearly relate to distinct historical formations. A' 15th 204 century carbon 14 date from the lower deposit of Eko Abetu, indicates that the lower deposit of Eko Abetu probably dates to the last 500 years.(16) It does not follow that one cultural deposit follows the other without a break or that the deposits or components are necessarily contemoporary, or that other components may not exist on the northwest. In fact, the absence of any absolute date from the Uwan Living site, has made it difficult to stratigraphically relate the Eko Abetu and Uwan sites together. Dating evidence such as the frond impressed/twisted cord roulette, suggested by Darling (1984), is, in the opinion of the invesstigator not secure. Stratigraphic evidence in the Benin area, needs to be provided to prove that the twisted cord (fine) is earlier than the frond impressed. However, chi-square determinations on body decoration has allowed the investigator to group the Eko Abetu deposits into 3. By the association of the two lower excavation levels (which. can be assumed to correspond to the lower cultural deposit) of X2 and Y2 and the non-association of these with both their upper levels and the levels of B1, these lower levels of X2 and Y2 can be said to belong to the early occupation of the site which occurred about 500 years ago. By the lack of association of the lower levels of B1 with its upper levels, and the levels of trenches X2 and Y2, these two levels of trench B1 represent a gap in the 205 utilisation of the X2 and Y2 location. This was therefore a middle phase occupation of the Eko Abetu site. The recent occupation of the site relate to the building phase of X2 and Y2, and the recent pottery in level 1 of trench B1. A 3- phase occupation of the Eko Abetu site would be consistent with an average of about 100 years life span for each phase. This time span may correspond to the life and decay of mud wall villages in West Africa. The t-test and cluster of Jaccard matrix generally support this correlation (see figure 33). This sequence relates well to the Benin City chronology. The investigations of Connah (1975, Ryder 1975:243), indicates that Benin palaces were established at about the 13th century. The Benin system of territorial and defensive earthworks are thought to have been constructed by about the 15th century by Oba Ewuare. From about the 17th century, the kingship was transformed from a ”warrior" ruler into a "ritual figure rigorously secluded within the palace" as is suggested by the intensive use of the palace during the middle phase occupation of the Clerk’s Quarter’s site. In 1897, the colonial period sets in as the Oba was barnished to Calabar by a British punitive force. It would therefore appear that the Eko Abetu was first occupied around the period of Ewuare. It is in fact usual for people on the northwest and north of Benin City to attribute the origin of their settlements to the reign of Oba 206 Ewuare. (Egharevba 1968). Informants told the investigator that the Uwan and Ogbogiobo (close to Uwan) villages were established by members of the Benin royal family during the period of Ewuare. However, it has been possible in this research to suggest a chronology for the Eko Abetu site on the basis of artifact associations. The Eko Abetu sequence looks like a reasonable chronology for the northwest, going by the Benin City sequence. Oral historical data in general agree that settlements around Benin post-date Benin City itself. 7.22 Agggmptigp 2; Distinct ethnic or population groups are expressed in the archaeological contexts as lack of association between artifact types. In Iron Age studies in East and southern Africa, stylistic cultural attributes have been used successfully to identify ethnic or linguistic groups and their historical movements. For example, East African Early Iron Age peoples are often distinguished by comb stamped decoration on ceramics as distinct from roulette decoration of the Nilotic peoples of the north (Huffman 1982:132). The point here is whether the cultural phases identified on the northwest can similarly be said to relate to distinct ethnic traditions. Several lines of evidence argue on the contrary, or that there is continuity of the northwest deposits to present local Bini people. The point has already been made that some of the northwest settlements were established by people from the 207 city center. Also, although the Eko Abetu and the Uwan living sites can be distinguished by some pottery types (see Figures 42 and 51) and decorative motifs, such as the twisted cord and frond impressed, for example, these attributes are not unique to the northwest. All. the pottery types identified on the northwest have been similarly identified at the city center, and roulette and comb stamped decorations are widespread in the Edo speaking area. This is indicative of the continuity and homogeneity of the tradition. Fortunately, historical records which date to the late 15th century, also suggest continuity in the tradition in spite of some conflicting reports (Connah 1967:597-598, Ryder 1965). At least the pottery tradition does not suggest a break or ethnic differentiation. 7.23 Assumption Q; There is a relationship between artifact variability or variability of design attributes on artifacts and the settlement and residence type. Closely connected to the idea of continuity in the tradition is the need to explain what is responsible for the observed variability in the northwest pottery. In the analysis, pottery variability, based mainly on chi-square determinations and cluster of Jaccard matrix, highlighted two key explanatory variables, namely, temporal and spatial. But the point is that the attribute distinctions both temporally and spatially relate to behavioral differentiations within a continuous tradition. 208 Although the variability does not specifically identify pottery types, it can suggest site function indirectly, for example. But what kind of function? Bini people identify pot form and it’s function as follows: (Connah 1975:115-133, Thomas 1910b, Omokhodion 1986b) Akhg: This is commonly a necked pot but may also be a globular pot or large forms of type E of Eko Abetu site (see Figure 42). The general purpose is for storage of water or grains. They are also used for heavy duty cooking e.g. cooking yams for a community workforce or for cooking oil palm seeds. The small form of the pot (gybi;gkhg - meaning small pot) is regularly used to cook yams for the immediate family, depending on the size of the family unit. Egan; This term generally refers to bowls, used for cooking soup and serving food (see Figures 42C,D,F and 51J, K). Similarly, a small bowl is described as vai-gwggg. Qkpgtg; The word literally means ”for washing the hand". Forms (Figures) 426 and 51K can be used for this purpose. They are usually small bowls. The point in the above is that pot use amongst the Bini people is quite ltmttgg (from narrow options) and peggigtggtt The regular use of a pot is for cooking yams and soup. This is a persistent cultural behavior. Traditionally it was common for families to cook and eat yams three times in a day.(17) Repetitive cultural function cannot confer 209 variability. Because of the degree of regularity of design elements, tegombigatigg (which causes variability in design attributes) is a fggtign of the mghilitz of pot ptgfiggezg and ggztiggg. Specialised purpose use of pots, for example, as in ritual contexts, (ritual function is often culturally mute, and hence difficult to identify) is unlikely to create a distinction in pottery analysis, since the same regular pots are often used for ritual offerings. Models of seasonal activities would be difficult to apply to highly sedentary yam farmers. Temperature, which is a severe seasonal determinant in temperate climate is not a significant variable under tropical conditions. Even if someone wished to relate the limited function to the pottery type, the chi- square calculations were based on body decoration, and decoration. may not be expected to express function. Differences in pot form are more expressed on the rim than on body decoration. Also there is no evidence for labor- intensive production of pots in Benin. (Feinman gt 3; 1981, Upham gt a; 1981). Production of Benin pottery was part- time, unspecialized and a village activity. A compelling explanation for pottery variability on the northwest therefore, must account for the Igggmhingtign of peggigtggt design attributes. This would be the case where women who pxgdngg and gggzz the pottery have limited design vocabulary and are mobile in W maidens... This point is consistent with a pgtzilgggllz based social system, 210 and Benin tradition is a typical example. Mobility in post- marriage residence does not imply descent. Patrilineality may only be expressed as an inference of patrilocality, given the context. The conclusion draws confidence from the studies of Deetz (1965) who has similarly related stylistic variability in American Indian Arikara ceramics to the changes in marriage and residence pattern.(18). Cultural persistence, pottery variability and patrilocality in Benin, fit very well the continuity in tradition already identified. Variability is reinforced by the characteristic non-sororal polygyny. Different pot carriers come to reside in the same location or different women produce different pots in the same location. However, the problem of representativeness of sample, makes this a tentative conclusion. 7.24 Agggmptign A; The relative occurrence of artifact type (or categories), between sites, ,can indicate a kind of exchange configuration which includes class and privileged access between sites or centers. Relationships between the northwest and the city center on the basis of occurrence of exotic or valued objects are fairly clear. There are few long-distance trade items in the northwest deposits. In level 4 of trench X2, Eko Abetu site, there is a small cowrie (probably of the moneta specie), and two gun flints. European bottle glass is present in the most recent level of trench B1 of Eko Abetu, and levels 1 and 3 of trench 410 of the Uwan living site. The spaces sampled 211 on the northwest and the city center (Connah 1975) are not directly comparable. Larger trenches have been excavated on the city center, but the occurrence of beads (?glass) in the city center and the absence of it on the northwest is quite significant (see tables 7, 10 of connah 1975). Glass beads ( a European import) were valued as ornaments, or often as symbols of rank to present day. In association with other lines of evidence, however, the city center was clearly a controlling center and the northwest like other outskirts settlements must have acted as service communities, providing farm produce to the city center or providing men for the military. Bradbury has illustrated the controlling mechanism adopted by Benin in trading relationship with Europeans. No “foreign" traders from the interior were permitted to operate in the Benin kingdom itself, and stringent controls were exercised over the waterside commerce with European and Itsekiri merchants. Heavy dues were demanded from visiting ships, the Oba’s monopolies in certain exports strictly enforced, and general trading was allowed when he and his chiefs had completed their business (Bradbury 1973:49). Although trade control during European contact must have added considerable power to the Obaship, it is unlikely that similar trading relationships prior to European influence could have been significant to account for the evolution of the kingship. Pre-European trade items that have been recognized in Benin include the cowrie, metals, and perhaps pottery. The extent of these early trades is poorly understood. 212 Other lines of evidence which mark out the city center from the northwest include the earthworks which show more complexity at the city, the elite architecture and art systems. 7.25 Agggmptign fit Artifact densities can suggest differential population sizes and social complexity. Population characteristics are important indices for explaining the degree of complexity of the cultural system. Cultural complexity could mean the growth of rank and control centers; development of new techno-economy; efficient energy extraction or increased per capita (imput) energy out-put (Harris 1977). It is possible, for example, to explain the relationship between population features and the labor cost for the construction of the Benin earthwork. The population census for 1952 indicates that Bini speaking peoples (Benin Division) numbered 292,000. Out of this figure, 52,000 people lived in the city center, the rest lived in several villages of large size (6,000), medium size (500) and small hamlets of about 20 people. The great majority of villages had the medium size figures of about 500 (Bradbury 1973:51). These figures are important from two angles. First, it is possible to suggest a significance for the Uwan wall on the basis of pottery densities and therefore the 213 associated population within and outside the wall. Looking at per c.c. pottery weights for the Eko Abetu and Uwan living site levels (Table 24-28), one could say that pottery density at Uwan is about twice that of Eko Abetu. Pottery density could reflect population or intensity of site use or pottery quality (e.g. coarse or fine). If one assumes a 2:1 population ratio, this would be comparable to the present conditions of the villages. Uwan is larger than Eko Abetu and they both fall within the medium size villages of Bradbury. A population ratio of 2:1 is not significant to suggest any difference in social complexity, and medium size villages, even in their present form could have been unable to organise for labor for the construction of the Uwan Wall. This point raises doubt about the relationship of the Uwan Wall with the northwest settlements identified so far. The second point also relates to the population of the city center and the construction of the defensive earthworks. Bradbury estimates that the population of the city center in 1897, must have been half it’s 52,000 figure in 1952. The implication of this is that at the time the innermost or lst concentric wall was constructed about 500 years ago, the population of the city could have been less than 10,000 or about the size of the existing large villages from the 1952 census. For the construction of the innermost wall, (which is about 9 kilometers in circumference and 17 meters high in recent condition) Daniels estimates (Connah 1967:606-608) 214 that it would have taken about 5000 men 97 days, working for 10 hours a day, to merely dig the ditch. The estimate does not include labor taken to heap the earth up into a high bank. The estimate probably assumes that agricultural hoes were used for the digging purpose.. Now, this work force estimate is difficult to apply to the population data and no evidence of organised labor-intensive slave service is known. Connah indicates (1967:608) that he could not say whether the labor force needed, could have been of "slaves or other origin". In addition, "tradition has nothing to say directly about these earthworks" (Ryder 1975:243). The construction of the earthworks of such magnitude, since these would have been major cultural achievements, ought to be well represented in mythology and the political art. The traditional names for the earthworks (125 in Bini and lzglg in Ishan) refer in general to a valley of two hills, sandwiching a ditch or depression. There is therefore a problem about the continuity of the earthworks (if they are artificial) with present population.. The point cast doubts on the military significance of the earthworks (Darling 1983, 1984). 215 7.3 Historical Implication In explaining the evolution of the ancient kingdom of Benin, there is no need in my opinion, to rely on insecure interpretations of military conquest or control of trade resources, when evidence from mythology (oral tradition) and social organisation are very strong pointers. This research has illustrated evidence for birth and sex principles in marriage, inheritance, architecture, and religion. Some of the evidence are surviving features of the people. The appointment of knowledgeable leaders to act as governors over people who may be unrelated to the original point of origin of the political institution is a common feature in political history. Colonial experience in Africa is a living evidence for this. It is therefore easy to rely on the evidence for Benin-Ife relationship and recognize features of Yoruba influences in Benin. Kingship mythology and regalia in Benin and the Yoruba states are similar. The term Qt; is a Yoruba word. In Benin City today, there is a rivalry between this introduced obaship and descendants of the original rulers of the people, of which the Ogiamwen institution is a survivor. The Qggnmila divination equipment, which is widely used amongst the Edo-speaking peoples today is clearly a Yoruba introduction. In Ifa mythology, Orunmila, otherwise known as gig, was one of the 401 divinities sent to the earth by Olodumgre, the Yoruba 216 High God. Orunmila was the one charged with the power of divination because of his great wisdom (Abimbola 1977:35). The ancient architecture and town plan of Benin is almost a copy of Yoruba designs. (Ojo 1966) But the more important or novel evidence from this research is the application of archaeological methods and techniques to identify the patrilocal mode of social organisation. This was based on the measure of variability which is an expression of pot production and carriage. Although the result is tentative (subject to confirmation), it is quite consistent with the characteristic sex symbolism, in which value is also placed on the taking of several wives (non-sororal polygyny). This, in fact may be one of the most important symbols in the evolution of the Benin kingship. When for example, Oba Ovonranmwen was deposed and exiled in 1897, he was found to have had about 80 wives ‘(Egharevba 1968:58). Historically therefore, Benin tradition is a patriarch institution, like many such traditions in Nigeria today. Apart from the nature of Benin-Ife relationship, evolution of a patriarch institution is a quite possible by a mere imposition, locally, of a divinity (e.g. a chiefship over previously segmentary tribal groups) who can convince others that the oracles have decreed his leadership. Very little research has been done in the Edo-speaking area on the great influence oraclular belief has on decisions and 217 action, and therefore its role in cultural change. The investigator has been told several times in divination clinics to begin to wear beads on his hands because he is a chief. There are examples in Nigeria today of very powerful religious patriarchs who are more like kings, and who explain their great power and influence to relationship with the divine. Influence, prestige, control of resources (including women), and even military suzerainty are usually the external expressions of this kind of underlying ideology. 7.3 Disgu§§ion It is necessary to comment further on the question of Benin-Ife relationship, since this has been used as a supporting arguement for the military determinism in the evolution of the kingdom. In this regard, the recent observation made by Darling (1984), regarding correlates between linguistic evidence and the distribution pattern of pottery and the earthworks, is a significant point. From linguistic evidence, it is thought that the origin of Benin is related to the split in the proto-Niger-Congo language, thought to have been spoken around the confluence of the Niger-Benue, some 3-6,000 years ago. (Darling 1984:63). From this split, ancestors of todays "southern Edo" (Urhobo/Isoko) (see Figure 5) must have migrated into their present locations in the swampy deltas about 2-3,000 years ago. Waves of migrations into the Edo speaking area followed this 218 and the territoriality associated with the movements resulted in linguistic differentiations presently noticed and the building of 125 or earthworks. The Bini and Ishan earthworks are therefore related to such migrants who penetrated into this area between 1 and 3 thousand years before present. Benin City emerged as a dominant center thereafter. Surface distribution of design elements on pottery such as the coarse string roulette, and the nodular carved wooden roulette appear to support the migration view. Secondly, archaeological evidence for iron using, immediately north of Benin and at Abakaliki to the east which generally date to the 7th and 9th centuries A.D. argues for a similar early period for Benin. (see Anozie 1976, for similarly early dates from the deltas). If this were so, then the association of Benin with Ife whose dates are largely post A.D. 800 would then be tenuous. This doubt about the historical relationship between Benin and Ife has also been expressed by Ryder (1965). Ryder had noticed that early Portuguese records on Benin did not mention Ife. In fact, Ife did not become current in Benin historiography until the last century. And that indications from historical records, and art tradition, suggest that Benin must have been related to the "Beni confederacy" (Ryder 1965:32), located around the confluence of the Niger and Benue rivers. That is, that the Portuguese were probably confusing “Beni” (thought to have been an ancient state on 219 the Niger/Benue confluence), with the present Benin City. The Maltese cross for example, (which was mentioned by the Portuguese visitor to Benin in the latter half of the 15th century). and the ritual associated with it, is not known in Ife art, which further argues against the Benin-Ife relationship. 1 Only one clear parallel to the Benin use of the Maltese cross has so far come to light in adjacent areas of Nigeria. This occurs in the standing bronze figure at Tada, a village a little to the south of the Niger and no more than ten miles from Jengi, said to have been the capital of the Gwagbaji- Beni (Ryder 1965:33). It is the opinion of Shaw (1973:237) however, that on technical and stylistic grounds, this particular standing bronze figure at Tada, and in fact the so-called Tsoede bronzes along the Niger, belong to Ife art. Also, the investigator has in this research, raised the problem of the continuity of the Benin earthworks with present populations, which casts doubts on their cultural significance. This does not nevertheless remove the doubts that have been raised concerning the relationships between Benin and Ife, but the point remains that no real good historical or archaeological evidence exist that seriously negates the Benin-Ife relationship. On the contrary, archaeological evidence support close ancient ties. Forms and decorative styles on pottery between present day Benin and Ife are quite similar. They share a common potsherd pavement flooring technique; the art and architecture are very close. In addition, the dates 220 of Ife are earlier than those of Benin, but even if earlier dates for Benin are established, this may yet not remove the close typological similarity between the cultural systems. Looking at typology for example, Igbo Ukwu is nearer to Benin, than Benin is to Ife. The dates of Igbo Ukwu are-in the 9th century and Igbo Ukwu cultural materials are significantly different from those of Benin and Ife. For example, although Igbo Ukwu pottery is "so highly decorated, roulettes have not been used at all" (Shaw 1977:85, 1970). This is not the case in Benin and Ife where rouletting constitute perhaps over 60 per cent of design elements. Also, metallic art of Igbo Ukwu consist of pure copper and heavily leaded bronze (high tin), while the Benin alloys are of brass (high zinc content), and Ife has almost pure copper and leaded brass, showing that the Benin materials are closer to Ife. However, a northern influence for these cultural traditions is not in doubt and this has generally been accepted, and in fact it is the opinion of Shaw (1973) that only a long distance network of trade to the north and the sahara could have ensured the provisions and introduction of the alloy for metallic art and the lost wax or Qigg perdue method of casting. However, debates about the typological and chronological distinctions between Benin and Ife have previously left unexplained the unique similarities between them. CHAPTER VIII WWW This research has been concerned about the problem of the origin of the ancient kingdom of Benin, through the study of artifact distribution on the northwest of the Benin City center. The study was put into perspective through a review of Benin research and related studies. The unique rainforest ecological conditions of Benin, was considered. The ecology partly influence the hoe agricultural economy, architecture and settlement. The people speak a language that belongs to the Kwa subgroup of the Niger-Congo. The patrilineage society is organised on two levels, namely, a village age-grade social organisation in which age is the criterion of authority, and the town or state social organisation in which authority is based on the rule of primogeniture (inheritance of first son). This unique social organisation is also based on sex because only men can participate in the two modes of social system. The society placed value on non-sororal polygyny (taking of wives from different locations), including the isolation of male and female in Benin architecture and in cult organisation. These values are based on mythological or religious belief systems. Ancient trading or diplomatic relationships involving Benin is reflected in the metallic art, ornaments (e.g. glass beads) and other items such as cowries. The importance of 221 [E1 222 trade in the evolution of Benin was considered. Also, recent studies (e.g Connah 1975, Darling 1984), on the distribution pattern of the Benin earthworks and its military implication have been critically assessed. This study adopted an approach in which new archaeological sites have been identified and excavated on the northwest of Benin City. The sites yielded mostly pottery materials which have been analysed . Inspite of methodological problems, this research has been able to suggest the following substantive conclusions: fit; A 3-phase occupation of the Eko Abetu site, which dates from about 500 years ago has been suggested, based on deductions and correlations of stratigraphy, chi-square results on body decoration, 'cluster of Jaccard coefficient, t-test, pottery typology and the single calibrated date of 1432 1 100, from the lower levels of trench Y2. The result is consistent with oral historical data which indicate that some of the northwest settlements were established during the reign of Oba Ewuare about 500 years ago. 8‘2 The research has also suggested a continuity of the northwest cultural deposits with present local population by the persistence of pottery forms. This conclusion isolates the possibility of a cultural break. 223 fitfi The variability discovered in the chi-square determinations on body decoration has been related to the recombination of persistent design attributes. RecombinatiOn of persistent design attributes on body decoration is only explained by the known patrilocal mobility of women in post- marriage residence. Other possible causes of variability such as function, seasonal activity and labor-intensive production have been isolated. It is stated that variability is reinforced by the characteristic non-sororal polygyny (different carriers of pot come to reside in the same location, or different women produce different pots in the same location). It is stated that this sex symbolism in which value is placed on the taking of several wives may be an underlying principle in the evolution of the Benin kingship. Political offices can originate by the elaboration of symbols which articulate their values. It is recognized that the deduction based on pottery variability is tentative because of the problem of representativeness of sample. fitfi Population characteristics have been related to the pottery density on the northwest. There is no evidence that these northwest settlements were more complex than what the 1952 census population census suggests. It is therefore suggested that medium size villages with populations of about 500 would have been unable to organise for labor for the construction of the Uwan wall. This point raised doubts 224 about the continuity of the Uwan wall with the northwest sites identified so far. The same point has been made concerning the city center. Apart from the fact that the methods by which the Benin City earthworks were constructed have not been identified, it is significant that the construction of earthworks of such magnitude (which would have been major cultural achievements) are not represented in mythology or the political art. The point therefore cast doubts on the continuity of the earthworks with present populations and hence their military implications. On the other hand, ancient diplomatic relationship between Benin and Ife is considered to be a likely explanation for the origin of the obaship. Several cultural features which are shared between Benin and the Yoruba states make this a compelling explanation. Methodologically, this research has been able to suggest three occupation deposits on the northwest of Benin City. The occupations could be found isolated in some sites, and there may be more components. Conclusion in this regard is also tentative subject to confirmation from other studies. In the pottery analysis, the Jaccard coefficient and chi-square determinations were found to be very convenient and also helpful in arriving at quick decisions as to the kind of relationship or association between assemblages. The value of objective methods such as these can not be overstated. It would be of interest if statistical 225 analytical techniques such as has been presented are frequently applied in West African Archaeololgy. It could stimulate students. The t-test determinations were not so successful and appear as suspect. It is not clear from this research whether a metric approach is appropriate, but one problem was that the lip thickness was difficult to read because of the curvature of some rims. Also it was a frustrating task to read the color of sherds on a Munsell. Further excavations are called for, to provide more evidence from the northwest. It would also be necessary to work on the south and north of Benin City, outside the Bini speaking area to provide clues as to relationship between Benin City with other Edo-speaking neighbors. W 1.

Information here is based on previous original study and construction by the author. The report has been accepted for publication by AMAN. Journal of society, culture and environment. Vol. 5 no. 1. 3. In 1982, a new town planning program for Benin requested me to prepare a report on the historical sites for the city. The report was titled "Sites and Buildings of Historical Importance". The materials are unpublished government documents, but information here is from the report. 4. The technical name for lkhtngtg is flewbogldia lggzis. 5. It was important for me to obtain a formal approval for the excavation from the Federal Department of Antiquities. I obtained this at the middle of December of 1985, from Mrs. A.K Fatunsin of the National Museum, Ibadan. Part of the condition under which this approval was to be obtained was that an archaeologist from one of the universities should agree to be my local field supervisor. This led me to travel to Nsukka on the 2nd of December to ask Dr. Fred Anozie of the Department of Archaeology, University of Nigeria, if he could act in that capacity for me. He kindly agreed. On 1, February, 1986, Dr Anozie was able to take time off his pressing duties at Nsukka to visit me on the sites. 6. 20 cm spits (arbitrary levels) were considered appropriate for the excavation on the northwest, on the basis of previous experience on some Nigerian sites. Secondly, seiving of the deposits was not carried out since careful probing with a trowel would be sensitive enough to the mainly expected pottery artifacts. 7. Old farm plots in this area are easily taken over by a nuisance weed which is locally called Awolowo (named after a political leader). The technical name of this weed is WW 8. Apart from pottery, no other significant cultural materials have been recovered from the northwest. Bone materials, for example, have been scanty and very fragmentary. 9. Jaccard coefficient was decided upon for it’s convenience in the transformaion of non-weighted nominal data. 226 227 10. Average linkage has the advantage of a rapid organizing principle, where new clusters are simply joined to existing cluster, by computing the average similarity of all relevant units (Hodson 1970:307). This cluster method also avoids the problem of chaining. The method was designed to cluster the excavation levels and not the attribute set as such. 11. T-test determination vis to determine association (patterning) or the lack of it, between excavation units on the basis of lip thickness. 12. Some carved wooden roulettes have been illustrated in Plates 5-9. The interesting point that would be obvious is that a great deal of error can arise if one wished to isolate the differential patterns typologically. For example, Darling (1984:267) typologically associated his "simple grid pattern" (CR1) with early Edo settlements. One point is that carved roulette patterns are rarely single. They are often multiple. In Plate 7-8, carved roulette is illustrated as either zigzag with vertical lines or vertical lines with basket work pattern. (Note Darling (p.225) illustrates "basket work pattern" as carved roulette 2 (CR2). Now, a nodular pattern could appear with a grid pattern etc, but in a sherd that is broken, an erroneous significance of a motif could be suggested (more so when attribute sample is low and unstratified). The typological and chronological relevance of the patterns are therefore basically suspect. I would prefer to go with David and Vidal (1977:44), and see carved roulettes as essentially illustrating the use of iron. 13. Probability chi-square.computation is fairly easy and straightforward to understand. Like the t-test, it was to search for patterning between excavation levels on the basis nominal pottery attributes. Note, that the patterning sought in these organizing principles is of a polythetic nature. That is, groupings are based on a sufficiency of conditions. (see Clarke 1968:37-38) 14. This dating sample has been kindly submitted on my behalf by Dr. Larry Robbins, Department of Anthropology, Michigan State University. 15. This motif has been described as coarse string roulette by others (e.g. Darling 1984:223, 266-267). It is illustrated in Plate 18, 19, 20. Specifically, the following is the way Darling has described it’s chronological importance, "Although CSR1 (coarse string roulette) is present on most of the sites which on other evidence appear to be early, both the early vessel forms (SQE 24/MSC 27) and the culture sequence chronology of the computer analysis 228 suggest that it occurred later than the bulk of the finer string roulettes. The change from the finer string roulettes (possibly made from savanna grasses to the coarse string roulettes (made from oil-palm leaf fibres) may have merely been the adoption of the new material from a different environment" (Darling 1984:266-267). A date from trench 420 of the Uwan sites would have been helpful in contributing further to this point about whether the frond roulette is earlier or later than the twisted cord roulette on the northwest. The point that can however be made here is that apart from the fact that the forest environment presents an array of rope fibres which can be plaited into fine or coarse roulettes, the frond roulette is better represented at the Uwan site, while the twisted cord roulette (fine string roulette) is more prevalent at Eko Abetu. Secondly, in my isolation of twisted cord from frond roulette, I was able to establish that the frond roulettes are characterised by not only a large (coarse) impression, but also the presence of negative impression of palm frond leaves, (These impressions are visible on Plate 20). If I was not able to do this, I might have grouped them under twisted cord. The following is the way Darling (1984:223) addresses the similar problem: "As no examples of twisted rather than plaited roulette were identified (Soper:1977; Pers comm 1979; 9-12), this group was categorized into degrees of coarseness for analysis". That is his plaited string roulettes were grouped into a continuum of sizes even without any objective measurement. The argument here is not that this could not be done, but that what is done, is influenced by the problem and techniques at hand. 16. The gun flints (which date to the post 17th century), in level 4 of trench X2 has been considered intrusive from the upper levels due to disturbance of this trench. Disturbance in X2 has been illustrated by the stratigraphy and the significant association of its excavation levels based on chi-square results (see table 15). 17. Yam is often processed as pounded yam (ignfign) and this is normally eaten with vegetable soup, such that the pot and bowl forms would tend to associate functionally. 18. Other workers (e.g. Hodder 1979) have drawn attention to the role of competitive exclusion (related to resource control) as a determinant of artifact variability especially across inter-tribal boundaries. Within-tribe variation can occur as result of symbolic constraints such as censureship or public opinion insisting on conformity (Hodder 1977:269). These interpretations in my opinion assume that the artifact traits in question are produced and used locally. In the case of Benin pottery, the importance of transportation or 229 carriage (Nicklin 1971:47) has been established, since Benin pots were produced in two pottery villages - Use and Utekon - (see Chapter V), from where they were most likely transported to other villages. There is no evidence for pottery production locally in the Eko Abetu and Uwan villages. Apart from this point, it should be recognized that the variability established in this research does not portray mutual exclusivity but a differential in the combination of traits. Patrilineal institutions however do maintain territorial village boundaries expressed in settlement and farmlands and perhaps in specific ancestral worship. But there is no direct relationship between these dimensions and pottery production and dispersal. Also exchange modes are really secondary factors. 230 LIST OF REFERENCES I."
