TenenkouMasks, figures & African art

Overview

The geographical distribution area of the terracotta sculptures classified as "Tenenkou style" is primarily centred on the inland Niger Delta in the present-day Republic of Mali, specifically on the administrative sector of the Cercle de Ténenkou within the superordinate region of Mopti. This hydrographically extraordinarily complex zone, characterised by the extensive seasonal floodplains of the Niger and Bani rivers, formed the ecological and logistical foundation for some of the earliest and most important urban centres in the whole of sub-Saharan Africa. The regular inundations (the so-called Crue) not only left behind fertile alluvial soils, but also forced the population to build their settlements on artificially heaped up mounds (Tells or Toguéré), which today function as primary archaeological sites.

The demographic structure of the Cercle de Ténenkou has a total population of 163,641 individuals, according to comprehensive census data from the Malian National Institute of Statistics (INSTAT) from 2009. This population is spread over a territory of 11,297 square kilometres, which corresponds to an average population density of 14.48 inhabitants per square kilometre. The gender distribution is almost equal with 80,218 male and 82,706 female inhabitants. More recent demographic modelling and estimates for the year 2023 point to continued, substantial population growth, which poses considerable socio-economic challenges for the region. The Cercle is administratively divided into ten municipalities, whose specific population figures illustrate the micro-regional density distribution.

Linguistically and ethnographically, the region is characterised by remarkable diversity and fluidity. Languages of the large Niger-Congo language family dominate in the Inland Niger Delta. The Mande language group is represented by the Bambara (Bamana), Soninke and Malinke, while the Atlantic language group is represented by the Fulfulde of the Peulh (Fulbe). The Soninke, as the historical founders of the Ghana Empire, and the Malinke, as the bearers of the heritage of the Mali Empire, play a central role in the deep historical structure of the region. In addition, there are Afro-Asian influences from nomadic Tuareg groups (Tamasheq) and the specialised fishing ethnic group of the Bozo, whose linguistic classification has some complex substrates. The self-designation of the ethnic groups often correlates with their economic specialisation, while foreign designations often reflect historical-political overlaps. The term "Bambara", for example, is partly an exonymic construct that was used by Muslim conquerors for the animist, "infidel" agriculturalists, while the self-designation "Bamana" is favoured.

The social structure of the populations living in the Inland Niger Delta is profoundly hierarchical and by no means organised acephalously. The social system of the Peulh (Fulbe), who represent a demographically and politically influential group in Ténenkou, exemplifies this stratification in an extreme form. The society is primarily divided into a dominant nobility (Rimbe), which in turn is subdivided into a secular political elite (Weheebe), religious Islamic authorities (Modibaabe) and land-owning nomadic herders (Seedobe). Below this nobility there are highly segregated, endogamous artisan castes (Waalobe), which include the griots (bards), leather workers and especially the blacksmiths and potters. The lowest level of the social pyramid is formed by the descendants of former slaves (Rimaibe), who were traditionally tied to the land and had to perform forced agricultural labour for the ruling nobility. This strict social and occupational segmentation, combined with a patrilineal kinship system, is of fundamental importance for the interpretation of art production. The production of ritual objects made of clay and metal was reserved exclusively for the so-called Nyamakala castes, specifically the blacksmiths (Numu) and their wives, the potters.

The subsistence strategies of the region are inextricably linked to the seasonal fluctuations of the Niger River system and require a high degree of interdependent co-operation between the ethnic groups. The agro-cultural groups (such as the Bambara and Rimaibe) focus on the cultivation of millet, sorghum and especially wet rice in the alluvial plains. The Peulh practise a complex transhumant pastoral economy that relies heavily on access to the highly nutritious bourgou grass (Echinocloa stagnina) that grows in the waterholes and depressions after the floods recede. The Bozo have specialised in the intensive fishing exploitation of rivers and temporary lakes. The relationship with neighbouring peoples is historically and currently characterised by this symbiotic division of labour, but is increasingly overshadowed by violent conflicts due to resource scarcity, ecological stress and the disintegration of traditional land use rights (Dina system). In particular, the tensions between the agrarian Bambara and the pastoral Peulh in the Cercle de Ténenkou have recently escalated into open, sometimes politically instrumentalised inter-communal conflicts.

In the art-historical and archaeological classification, an elementary theoretical controversy must be explicitly marked at this point. The term "Tenenkou style" is primarily a typological construct of the Western art market and formalist style analysis, but not a clear-cut archaeological or ethnic reality. While collectors and dealers subsume terracottas with specific zoomorphic features or more robust proportions under the geographical label "Tenenkou" (as opposed to the classic "Djenné style"), scientific field research reveals a far more complex picture. Excavations at the Natamatao (Thial) site in the Cercle de Ténenkou have unequivocally demonstrated that pieces in the so-called Tenenkou style and fragments of sculptures in the classical Djenné style coexist in the same stratigraphic layers or closely neighbouring ritual contexts. The sources are ambiguous with regard to the causal factors of this stylistic symbiosis. It is disputed whether these variations can be attributed to different chronological phases of creation, to the presence of different workshops, to different functional requirements in the ritual system or to an overarching, supra-regional identity of the Inland Niger Delta. Irrespective of this nomenclatural debate, objects of this provenance are treated in scientific discourses and national institutions such as the Musée national du Mali as an integral, structurally related cultural heritage of the comprehensive Mande ecumene in the inland Niger Delta.

Cultural context

The religious system from which the fascinating terracotta sculptures of the Inland Niger Delta emerged eludes a complete historical reconstruction due to the early and far-reaching Islamisation of the region (which began in the 11th century and culminated in theocratic states in the 19th century). Nevertheless, fundamental cosmological principles of order can be derived from the analysis of archaeological findings, historical Arabic sources and, in particular, from the comparative study of the oral traditions of the recent Mande populations. The original belief system was profoundly animistic and was based on a complex pantheon of creator gods, nature and earth spirits as well as an omnipresent ancestor cult.

In the cosmological order of the Mande peoples (which included the Soninke and Malinke), the so-called Bida serpent cult, which is handed down from the myths of origin of the Wagadu empire (the historical Ghana empire), played an absolutely central role. According to oral tradition, the serpent spirit Bida was the guarantor of fertility, rain and the prosperity of the empire, but demanded cyclical human offerings (traditionally a virgin) in return. In this belief system, snakes did not function as profane animals, but as physical manifestations of ancestral spirits endowed with extremely ambivalent power. They possessed the dual ability to both punish their descendants with devastating diseases and to initiate miraculous healings. The ubiquitous iconography of snakes, which can be found on countless terracotta sculptures from the Djenné and Tenenkou regions as plastic applications (often coiled around the body of the figures), is therefore interpreted by researchers as a direct reference to this snake cult. The sculptures probably served as medial instruments to enforce the favour of the spirits in times of crisis (such as the devastating drought which, according to the myth, followed the killing of the snake Bida) or to request ritual healings.

The ritual authorities in this system were not necessarily formalised priestly castes, as they exist in Western understanding, but were primarily recruited from the members of the endogamous artisan castes, the Nyamakala. At the centre of this system was the concept of nyama, an invisible, malleable but potentially highly dangerous spiritual life energy or vital force. Only individuals born into these castes - specifically the blacksmiths (numu) - possessed the innate ability and esoteric knowledge to safely manipulate and channel this energy. The blacksmiths and especially their wives, who traditionally acted as potters, were believed to have an inherent spiritual power as they transformed the elements of earth, water and fire. The clay of the Niger Delta was not regarded as dead matter, but as the seat of territorial earth spirits. The role of women in the cult was therefore of paramount technical and spiritual importance. As the creators of the terracotta sculptures, the women were not merely craftswomen, but indispensable ritual mediators. Through the act of modelling and firing, they transformed raw, spiritually charged material into activated "power objects", which were used in initiation societies and healing cults.

What significantly distinguishes this religious system structurally from the cults of neighbouring peoples is the materiality and the nature of the performance of the ritual objects. While societies such as the Dogon on the Bandiagara escarpment or the Senufo in the south primarily used wooden masks (for the Awa and Poro secret societies respectively), which were worn by male initiates in loud, highly public, kinetic and choreographed rites of passage and death (such as the Dama dance), the terracottas of the Inland Niger Delta fulfilled a fundamentally different function. They were primarily stationary, hidden altar objects. Archaeological and ethnographic evidence suggests that these sculptures were worshipped in private sanctuaries, walled into the earthen foundations of dwellings or arranged on collective earthen altars protected by domes. Their power worked through their static presence, not through performative movement. The numerous depictions of pathological symptoms on the bodies of the sculptures - such as eruptions interpreted as smallpox, subcutaneous nodules (onchocerciasis/flux blindness) or bone lesions (secondary syphilis) - also point to highly specialised, individualised healing cults that are absolutely unprecedented in sub-Saharan African art in this density and form.

This interpretation has sparked the sharpest and most intense methodological research controversy in West African art history: the debate between the art historian Bernard de Grunne and the archaeologists Roderick and Susan McIntosh. Bernard de Grunne approaches the religious context through a dedicated "aesthetic formalism". He utilises Mande myths and meticulously identifies 66 different 'sacred postures' throughout the Delta sculptural corpus. De Grunne argues that these gestures (such as kneeling with folded arms, clasping one's own leg or asymmetrical arm postures) represent a coherent, codified Mande prayer and ritual system that has remained stable over centuries. This introspective methodology is vehemently rejected by Roderick McIntosh (1992). McIntosh criticises this approach as "idealistic empathy" and criticises the fact that objects torn from their stratigraphic context by illegal looting cannot be understood through the uncritical back-projection of recent oral traditions. He warns against ignoring centuries of massive social transformation and Islamisation and postulating a static "stylistic fixity". From an archaeological perspective, McIntosh argues, this art-historical formalism serves primarily to fill the vacuum of lost context in order to legitimise the Western art market, rather than to explore the real, dynamic social function of objects in prehistory. Despite these fundamental discrepancies, the sculptures are undisputedly material witnesses to a highly complex ritual system that is held in the highest esteem in Western collections such as the Metropolitan Museum of Art due to its psychological depth and compositional density.

Aesthetic features

The terracotta sculpture of the Inland Niger Delta exhibits a canonical object typology that encompasses an enormous range from purely anthropomorphic to strictly zoomorphic representations. The specific subtype "Tenenkou", which is particularly localised in the region around Léré and Tenenkou, is iconographically associated in art-historical classification and on the art market primarily with the depiction of mythical, often hybrid animal beings (quadrupeds). These zoomorphic figures are characterised by robust, massively modelled legs, cylindrical bodies, striking raised collars and a sometimes aggressive or alert physiognomy, which is occasionally mistakenly interpreted as a lion or hartebeest. A significant sub-category is formed by equestrian motifs in which these hybrid animals are ridden by warriors or ritual specialists, symbolising the historical relevance of cavalry for the expansion of the Sahel empires and the control of the trans-Saharan trade routes.

This robust, compact canon of proportions of the Tenenkou style contrasts markedly with the classic "Djenné style". The latter is characterised by extremely elongated body proportions, narrow, cylindrical torsos, squared-off shoulders and extremely fine facial modelling. Iconographic constants of the Djenné style, which were also occasionally adapted in peripheral regions such as Tenenkou, are the striking almond-shaped eyes with the characteristic "multiple eyelashes", strongly protruding, often open lips, elongated necks and the detailed elaboration of scarification marks and ornamental body jewellery. Other prominent motifs include "maternités" (mother-child depictions), in which children are often depicted as miniature adults to symbolise tutelary (protective) entities, as well as figures whose bodies are completely covered by plastically applied pustules, concentric circles or snake motifs. The size range of the documented artefacts is variable, typically between 20 and 60 centimetres in height or length, although some monumental pieces can reach larger dimensions.

The choice of material is naturally limited to the local clay of the Niger alluvial plains. However, a decisive technological feature is the addition of levelling agents (so-called grog or chamotte), consisting of finely crushed, already fired clay shards or quartz grains. This technique was chemically and physically essential to ensure the structural integrity of the often thick-walled sculptures and to prevent catastrophic cracking during the firing process, which most likely took place in uncontrolled open field kilns at moderate temperatures. The development of the patina is a bimodal process. First, the finished, but still unfired sculpture was often coated with an iron oxide-containing, reddish or beige clay slip (slip/engobe) and intensively polished to create a smooth, closed surface. However, the often rough or encrusted patina visible today is primarily the result of centuries of post-depositional soil storage, which led to mineral precipitation, as well as active ritual use.

This is where the decisive difference between an activated ritual object and a profane object (such as a water carafe) manifests itself. The materiality of a profane vessel remains primarily functional and decorative. A ritually activated object, on the other hand, has accumulated thick, opaque sacrificial crusts over decades or centuries. These crusts result from the repeated ceremonial application of animal blood, millet porridge, red ochre or vegetable libations, which were intended to charge the sculpture with nyama. This ritual crust is an elementary component of the work's spiritual identity and not mere dirt.

The identification of "master hands" or specific workshops known by name is a highly complex endeavour in African art history. The art historian Bernard de Grunne has transferred this concept, which is anchored in Western art history, to the terracottas of the Inland Niger Delta. Through meticulous morphological analyses of details, he attempted to isolate the individual "signatures" of anonymous masters or stylistically homogeneous workshops, similar to his methodology for classifying the Baule style in the Ivory Coast. Although this concept leads to considerable price increases on the international art market and a nobilitisation of the objects, it remains speculative in academic archaeology. The collective, tradition-bound production within the exclusive pottery boxes, in which techniques and formal vocabulary were passed on matrilineally over generations, obscures individual signatures in favour of a strict, religiously motivated canon.

Due to the enormous market-relevant added value - intact objects from Jenne or Tenenkou often fetch five- to six-figure sums at auction - the problem of forgery is virulent and highly professionalised. Authenticity criteria from wood art (such as termite damage or cracks in the heartwood) naturally do not apply to ceramics. Visual inspection of the patina is inadequate, as Malian forgers have perfected techniques for artificially applying earth crusts chemically. The decisive scientific forensics is based on thermoluminescence analysis (TL test). Leading laboratories (such as Kotalla or Oxford Authentication) take material samples (approx. 2-3 cm³), heat them and measure the emitted light energy (luminescence signal), which is proportional to the absorbed radioactive radiation since the last firing process.

Despite these technological countermeasures, the purchase of terracottas without an established provenance from before 1970 remains a significant risk for private collectors, which emphasises the need for exhaustive scientific appraisals.

Ritual practice

For decades, the detailed understanding of ritual practice, in particular altar use, performance and the lifecycle of the terracotta sculptures of the Inland Niger Delta, was primarily based on speculation and extrapolation of oral traditions. This changed fundamentally with the systematic archaeological rescue excavations carried out by the Franco-Malian mission under the direction of Jean Polet and Bourahima Ouedraogo from 2001 onwards at the Natamatao site near the village of Thial (Cercle de Ténenkou). These findings provide an extremely rare, stratigraphically verified blueprint for the in-situ use of these objects in West African archaeology and refute the assumption of a purely mobile ritual practice.

The architectural structure of the altar system (specifically on the so-called East Mound of Natamatao) testifies to an immense ritual and material investment by the community. The basis was formed by a complex substructure that could be dated by radiocarbon dating to the phase between 1155 and 1316 AD. Within this area, hundreds of terracotta sculptures - including significant portions of the robust, zoomorphic Tenenkou style - were presumably positioned in strict linear formations. This arrangement does not suggest a random deposition, but a choreographed spiritual army or ancestral line. To protect these sculptures from the weather and demarcate the sacred space, they were covered by a dome-like architectural structure (a dome) made of clay.

The ritual activation of this sanctuary involved far more than simply setting up the clay sculptures. It was closely linked to the incorporation of extremely valuable, external status goods. In direct association with the sculptures, the excavators found bundles of massive brass ingots whose metallurgical analysis revealed a considerable zinc content of up to 20 % as well as lead, which proves their origin from the trans-Saharan long-distance trade (presumably via routes from North Africa or the Ijafen depot). Also noteworthy was the deposition of a dedicated jeweller's anvil made of brass. This combination of terracotta gods and forging tools impressively supports the ethnographic theory that the ritual system was deeply rooted in the esoteric power (nyama) of the metallurgists and pottery boxes. The altar thus functioned as an energetic hub where local earth spirits were fused with the wealth of global trade.

The offerings made to maintain, appease or renew the spiritual power of the altar were monumental in scale. In shallow pits subsequently dug into the roof of the protective dome structure, archaeologists identified successive deposits of complete animal carcasses. These victims consisted primarily of equids (horses or donkeys) and individual bovids (cattle). The carcasses were not intended for profane consumption; their skeletons were intensively and extensively coated with red ochre. In the cosmology of the Mande ecumene, red ochre is strongly associated with blood, life force, transformation and the world of the ancestors. Radiocarbon dating of the oldest of these animal sacrifices to the period from 1443 to 1647 AD proves that the altar was not static, but was continuously maintained and ritually served over a period of several centuries, long after the original dome structure had been erected.

The data points to a significant decline of the Natamatao cult in the mid-17th century. However, the deactivation or disposal of these sanctuaries apparently did not occur through profane destruction or hasty abandonment. The excavations indicate that the entire structure was intentionally and ritually sealed in its final phase of use. A thick layer of greenish clay was spread over the entire complex, hermetically enclosing the sculptures, the brass ingots and the sacrificial pits. This practice proves that the lifecycle of the sculptures - from the moulding by the potter from clay loaded with nyama, through centuries of venerative activation with ochre and animal blood, to the ceremonial burial - followed a strict ritual protocol. The activated object did not simply lose its power, it was respectfully returned to the earth. Regional variations in the Inland Niger Delta also included individual figures being walled into house walls for private protection, but the collective, dome-like altars of the Natamatao type represent the pinnacle of institutionalised ritual practice.

Historical context

The historical localisation of the terracotta art of the Inland Niger Delta correlates closely with the complex migratory movements, the climatic history and the rise of the great trans-Saharan trading empires in West Africa. The systematic settlement of the alluvial plains and the establishment of the first urban centres such as Jenne-jeno (the oldest known urban centre in sub-Saharan Africa) began as early as 250 BC. This civilisation went through several archaeological phases and reached its demographic and economic peak between 750 and 1100 AD, which was accompanied by the massive expansion of the gold and copper trade in the region.

Art production in the form of highly developed terracotta sculptures experienced its absolute heyday during this period (around the 11th to 15th centuries). The dating controversies in research often relate to the abrupt decline of this culture. Around 1400 AD, but at the latest in the course of the 16th century, centres such as Jenne-jeno were successively abandoned. While some historians attribute this collapse primarily to ecological factors - in particular devastating, prolonged periods of drought - other researchers argue that the increasing influence of Islam was the decisive factor. Islam, which was increasingly adopted as the state religion from the 13th century onwards by rulers such as Koi Konboro, demanded strict aniconism (a ban on images). This led to the marginalisation and ultimately the abandonment of the animistic ancestor and snake cults, which irrevocably ended the production of terracottas.

The influence of European colonial history (the formal French conquest of Sudan did not take place until 1893) on the original art production of terracottas was therefore non-existent, as the tradition had already died out centuries earlier. All the more catastrophic, however, was the subsequent Western influence on the reception and physical preservation of this cultural heritage. The colonial encounter initially initiated the interest in West African wood art, but from the middle of the 20th century onwards it increasingly shifted to archaeological artefacts when the first French officials and engineers came across the sculptures during infrastructure projects.

Modern market history in the West and the associated looting crisis took a dramatic turn in the 1970s. The devastating Sahel drought of that decade destroyed the livelihoods of countless farmers (often from the Dogon or Bobo ethnic groups), which drove them to systematically search the archaeological mounds (Toguéré) visible everywhere in the landscape for saleable artefacts ("subsistence digging"). The absolute market breakthrough - and the associated price explosion - came in 1980 with the ground-breaking exhibition Terres cuites anciennes de l'Ouest africain in Louvain-la-Neuve. This was curated by the art historian and dealer Bernard de Grunne, based on the immense private collection of his father, Baudouin de Grunne. This exhibition and the accompanying dissertation de facto created the art-historical brand logo "Djenné" (and derivatives such as "Tenenkou") through formal stylistic analysis and gave the objects torn from the ground an official intellectual legitimisation and a sales-promoting pedigree.

The price trend on the art market escalated dramatically as a result. In 1991, at a Sotheby's auction in New York, a terracotta ram figure from the inland Niger Delta measuring over 80 centimetres was sold for the then record sum of USD 275,000. The tragedy and ethical problem of this market dynamic lies in a paradox that is often cited: Even the legal, highly scientific archaeological campaigns of researchers Roderick and Susan McIntosh in the late 1970s (which led to the discovery of a famous headless torso that now rests in the Musée national du Mali) inadvertently contributed to the prominence of the "Djenné" logo through global media attention and fuelled demand.

These astronomical profit margins drove the informal excavations into a phase of organised, quasi-industrial looting. Local farming families, financed by regional middlemen and international networks (similar to the Artefact Rescuers Association of Nigeria, ARAN, which is active in the illegal nok trade), destroyed the fragile stratifications of the tell settlements. Archaeologists estimate that today between 80 % and 90 % of the known archaeological sites in Mali have been irreversibly looted. This disaster culminated in spring 1990 directly at the epicentre of the Tenenkou style, at the Natamatao (Thial) site. After a local farmer discovered a figurine by chance, the area was transformed into a huge illegal labour camp within days. Over 200 looters from the neighbouring villages ransacked the site day and night. The devastation only ended when the instability of the deep shafts led to the collapse of a tunnel, resulting in the death of a digger and forcing the gendarmerie to intervene.

In addition to the destruction of the archaeological heritage, the market created a massive counterfeiting problem. Counterfeiters in Mali, but also in transit countries such as Cameroon or Togo, reacted quickly to the demand. They learnt techniques to perfectly imitate simple authenticity criteria such as simulated earth crusts (patina). Even forensic thermoluminescence dating, considered the gold standard in Western laboratories, was compromised at times when forgers began to pulverise masses of available ancient but undecorated and worthless clay shards and combine them with modern resins to create new sculptures that simulated the correct radiological age. For this reason, reputable auction houses and museums today not only demand TL certificates, but increasingly resort to 3D X-ray and CT scans (such as Marc Ghysels' analyses for the Rietberg Zurich) to validate the internal, structural integrity of the artworks and protect the heritage of this ancient civilisation from complete falsification.
