Introduction

The information presented here was gathered during a decade of work as a Veterinary Officer in northern Turkana County, an area of Kenya west of Lake Turkana, bordering Sudan, Uganda and Ethiopia (Fig. 1), and various travels to north-eastern Uganda (Karamoja, Kidepo).

Study area

The area is populated by the Turkana, a homogeneous Eastern Nilotic group belonging to the “Karamajong Cluster”, comprising several closely related ethnic groups that speak a mutually intelligible language. The component tribes include the Karamajong, Jie, Dodoth, Teso (Uganda), Toposa, Jiye (South Sudan) and Nyangatom (Ethiopia) (Gulliver 1952b, 1966, Lamphear 1976, 1988, McCabe 1995, Lokuruka and Lokuruka 2006). Geographically, the region is made up of open plains with sparse scattered mountain ranges and several seasonal rivers. The area is characterized by high temperatures, frequently exceeding 30 °C, and aridity, with an annual rainfall generally in the range of 200 to 300 mm, which falls in very scattered and highly irregular showers (Turkana County Government 2013). Droughts are common, and while areas of higher elevation receive more rainfall, agriculture is limited to a few riverine zones (McCabe 1987, Rutten 1989, Opiyo et al. 2015). Because of such harsh ecological conditions, the Turkana are highly mobile pastoralists, managing a variety of livestock species (small stock, donkeys, cattle and camels) and balancing the challenges of living in an unpredictable ecosystem with a complex social network (Gulliver 1958, Wienpahl 1984, McCabe 1990, 1995, De Vries et al. 2006, Juma 2009, 2016).

Methods

For the Turkana and all the ethnic groups of the Karamajong Cluster, as well as to various degrees many of their neighbours - the Mursi, Dassanetch, Hamar, Suri and other more distant groups such as the Nuer, Ngok Dinka, Longarim (Herskovits 1926, Nalder 1937, Hazama 2012), cattle are the most prized livestock. Cattle are not only a source of food, supplying meat, milk and blood, but they are also overwhelming important in all aspects of social life (Cummins 1904, Evans-Pritchard 1940, 1953, 1956, Beaton 1950, Clark 1952, Kronenberg 1961, Gulliver 1966, Gourley 1972, Tornay 1981, Fukui 1984, Abbink 2003, Dubosson 2014, Insoll et al. 2015). Among the listed ethnic groups, a man is known by his contemporaries and friends not only by his given birth name but also by his “ox-name” - the name of his “favourite-ox”, which denotes specific and distinctive characteristics of the chosen ox, including colour of the coat, presence and patterns of spots, shape of horns, fatness or behaviour (Evans-Pritchard 1934, 1940, 1956, Gulliver 1951, Almagor 1972, Tornay 1981, Brown 1990, Dubosson 2014). Turkana adherence to such social custom is highly developed, and the ox-name of the favourite-ox - emong lodwarat (Ohta 1987) or emong lo edwaritae (Barret 1998) - is widely used to identify a man in addition to his birth name (Barton 1921, Gulliver 1952a, 1966, Gourley 1972). The ox-name is regularly used by the Turkana in social interactions, including dances where Turkana singers extol the qualities of their favourite-ox (Gulliver 1951, 1952a, Robbins and Robbins 1971, Ohta 1987, Barrett 1998, Hazama 2012). The favourite-ox of the Turkana is generally a castrated male with a very particular appearance, artificially developed through a variety of complex coat and body modifications and horn deformation (Gulliver 1951, 1952a, Evans-Pritchard 1953, 1956, Almagor 1972, Turton 1980, Brown 1990, Dubosson 2014, Insoll et al. 2015). While a Turkana woman may own livestock, the feature of the ox-name is an entirely male feature. As reported by Gulliver (Gulliver 1966: 59), male children from the age of about four years receive an ox-name from their father or uncles.

Results and Discussions

The cattle chosen by a Turkana to become “favourite-oxen” are invariably castrated at one to two years of age. Castration can be surgical, involving physical removal of testes through cuts in the scrotum, or non-surgical using a wooden hammer (ekidonget) and repeatedly beating the spermatic cord areas over the base of scrotum on an underlining wooden surface. The trauma disrupts blood supply to the testes, leading to subsequent tissue deterioration and atrophy. Castration is done to render the animal more docile and enhance growth, resulting in a taller and fatter animal that is better able to survive periodic fodder shortages. The preferred coat colour for a favourite-ox is uniform and pale, and can be white, gray, yellow or pale roan. However, in order to avoid competition, close agnates frequently choose cattle of different colours, even including brindled or pied coats. The preference for paler coat colours is because a coat “beautification” process is adopted: firing or branding in a specific pattern that causes the hairs of the fired area to grow back much darker than the surrounding undamaged skin. A paler background ensures a more visible result.

Pattern branding

The practice of “pattern branding” among the Turkana consists of branding a set of regular, geometric patterns over the coat of the favourite-ox. The custom has been documented in other ethnic groups neighboring the Turkana such as the Hamar (Dubosson 2014), Mursi (Insoll et al. 2015), Toposa, Karimojong, Jje, Dodoth (Gulliver 1952a, 1952b), Dassanetch (Almagor 1972), and Longarim (Kronenberg 1961). Pattern branding is done by using variously shaped iron implements that are not very dissimilar to the tools used in branding for traditional ethno-veterinary purposes (Mathan-Kumar et al. 2012) or those used to indicate ownership (Gramly 1975, Ohta 1984, 1987, Russell and Kiura 2011). Branding for ownership is a widespread husbandry practice adopted worldwide both by traditional pastoralists and modern commercial ranchers (Landais 2001) and even reportedly by ancient Egyptians as recorded in the painting of the Nebamun tomb from 1400 BC (Wilkinson 1979). Pattern branding, however, differs from ownership branding because the objective is not to obtain a permanent scar brand but a lesser degree of skin damage that allows coat hairs in the branded area to grow back. This is achieved by using a cooler branding iron and applying it to the coat for a shorter time so as not to kill the hair growth cells of the branded area. Hair grows back, but because of the increased concentration of the local skin pigment, it grows with much more of the original coat pigment. Gray hair thus grows back black, yellow hair dark brown and roan hair dark red. It must be noted that pattern branding is also different from freeze-branding because that destroys the pigment-producing cells in the hair follicles, resulting in the regrowth of white hair over the branded area (Hall et al. 2004). The end result of pattern branding can render the favourite-ox esthetically startling, as indicated by a variety of modified Turkana favourite-oxen in Figs. 2 and 3. Occasionally, pattern branding is simply limited to branding in a pinpoint pattern over the head of the ox to produce a pattern of numerous black spots (Fig. 7a) and on both sides of the tail (Fig. 7b).

History of pattern branding

Ox coat modification through pattern branding is a practice that has apparently been carried out for thousands of years and by numerous ethnic groups dispersed over a large geographical area. This is demonstrated by prehistoric rock art of cattle with unnatural coats from various regions in Africa. The Neolithic rock art at Sullum Ba’atti, Eritrea, depicts several cattle with coats of various geometrical patterns (Franchini 1951, 1952, Calegari 1999). Among the most intriguing examples are figures of cattle with vertical stripes on their coat (Fig. 4b) that are extremely similar to the favourite-ox of a modern-day Turkana (Fig. 4a). Such striped coat patterns for cattle are depicted in the rock art of Immidir, Algeria (Gauthier and Gauthier 2006), and Tassili-n-Ajjer, Algeria, which date to between 4000 and 2000 BC. Among cattle with normal coat colours, there are those with striped coats, described as “robe fantaisiste” or “fantasy coats” (Dupuy and Denis 2011). Another striking example of pattern branding in antiquity is the drawing of an ox with a circular pattern on its coat from 4000 BC rock art in Immidir, Algeria, (Fig. 4d) (Gauthier et al. 1996), which mirrors modern day branding of a Turkana favourite-ox (Fig. 4c).

Calegari). c “Circled ox”, Lotikipi Plain. d Ox with a similar coat modification from rock art found in Immidir, Algeria, approx 4000 BC (courtesy Y. Gauthier)

While it has been noted that some of the Turkana cattle pattern brandings resemble the engravings found on and around items at the Namoratunga archaeological burial site (Lynch and Robbins 1977), investigations have discounted any possible influence on recent Turkana occupation of such a geographical area and of the exceedingly “leading” approach used by Lynch and Robbins (1977) rather than one of actually comparing the engravings as they appear on Turkana livestock (Soper 1982, Russell and Kiura 2011).

Horn deformation

Another very visible body modification made to a Turkana’s favourite-ox is deformation of the animal’s horns by redirecting their growth. The practice of horn deformation is widely used among the Turkana, as evidenced by the richness of the Turkana’s vocabulary to describe the various horn shapes that can only be artificially achieved: 18 different terms for corresponding different artificial horns shapes (Ohta 1987). Horn shapes can be modified by carefully carving the horn in specific areas to stimulate its growth in a particular direction. However, to achieve the most radical horn shapes, the technique used by Turkana requires fracturing the horns so as to reposition them in a new direction. The procedure, carried on juvenile animals with horns that have already grown to a length of 10 to 15 cm, is done by repeatedly pounding around the base of the horn with a round smooth stone to weaken the bone core base and subsequently pulling and wresting the horn manually until the horn bone core at the base is fractured. Once this has been achieved, the horns are turned, twisted and bent in the direction in which they are desired to grow: being rotated and bent forward for a forward curved growth (Fig. 6a). In some cases, the fractured horns require to be kept in the chosen position artificially. If a vertical parallel growth is desired, the horns’ notched tips are tied to each other diagonally with a rope made usually with fibres of Sansevieria ehrenbergii (Fig. 5a). If asymmetric horn growth, “one up one down”, is desired (Fig. 6c), the fracturing procedure is carried out only on one horn, and after lowering the horn toward the front, a thread is attached to the notched horn tip of the modified horn to a purposely cut hide loop over the bridge of the nose. Horn deformation has been recorded for cattle of many other Eastern African ethnic groups: the Karimojong, Jie (Gulliver 1952b), Dodoth (Thomas 1966), Hamar (Dubosson 2014,), Bodi, Dassanech (Almagor 1972), Hamar (Chaix et al. 2012), Mursi (Insoll et al. 2015), Nyanyatom, Suri (Abbink 2003), Murle (Lewis 1972), Pokot (Brown 1990), Dinka, Nuer (Evans-Pritchard 1940, Seligman 1932) and Longarim (Kronenberg 1961).

History of horn deformation

There is evidence that horn deformation has been practiced by many ancient African ethnic groups. Many cattle skulls have been excavated from funerary bucranias (a set of cattle skulls place in or around a burial). Numerous cattle skulls placed in a croissant shape on the southern border of a tomb, in the eastern cemetery of the ancient (2500 to 1500 BC) city of Kerma (Honegger et al. 2009, Chaix et al. 2012), northern Sudan, revealed unnatural horn shapes, vertical parallel horns or one horn pointing downwards and the other upwards, suggesting that such shapes could only have been achieved by artificial means (Chaix 1996, 2001, 2004a, 2004b, 2006, Chaix and Hansen 2003). Such archeological findings were also discovered in burial areas closer to Egypt. Those in Faras (Hall 1962) suggested that such customs were also carried out by ancient Egyptians. This is confirmed by the representation of cattle with obvious artificial horn deformation on the East Wall reliefs of the tomb of Ptahhotep (Fig. 6d) (Quibell 1896), on the south wall of the offering hall of Manofer in Saqqara (Egypt) from approximately 2500 BC (Altenmüller 2006), in the decorated chapels of the Meroitic Pyramid at Meroe (Chapman and Dunham 1952) and in many other Egyptian bas-reliefs (Vandier 1969). The practice of horn deformation by ancient Egyptians may suggest that they were responsible for introducing such a custom southwards to other African ethnic groups (Seligman 1932, Seligman and Seligman 1950). While such a hypothesis is attractive, it is probably not the case because horn deformation is not continuously and commonly represented in Egyptian tombs (Schwabe 1984), and furthermore, artificial horn shapes have appeared in the rock art of various Neolithic cultures of several Saharan regions, all substantially pre-dating Egyptian civilization (Huard 1959, Huard and Massip 1963, Chaix 2004a, b, Searight 2004). For example, rock art of the Wadi Mathendous, in Libya, of approximately 7000 to 6000 BC, shows a similar technique used to maintain parallel vertical growth of the horns, the fractured horns being kept in the chosen position by a rope tied between the notched tips (Fig. 5b),

Modification of other body areas

In addition to the coat and the horns being modified, there are other body parts of a favourite-ox that may be the subject of modifications. Among the Turkana, as with many other pastoralist groups, the ears of the cattle are often chosen for making various types of ownership marks (Ohta 1987, Barrett 1998). However, for decoration purposes, a specific ear cut is implemented: a series of straight cuts, approximately 2 cm in length, are made across the upper and lower margins of both ears using a wrist knife (abarait) that every male Turkana wears (Fig. 7c). The Mursi of Ethiopia perform a similar pattern of ear cutting (Eczet 2015). The subsequent inevitable infection of the wounds in the cartilage along the ear margins ensures development of a well-spaced saw-tooth pattern (Fig. 7d). Another area occasionally selected for modification is the dewlap, where single (Fig. 8a) or multiple skin cuts (Fig. 8c) are made in such a way as to produce flaps of pendulous hanging skin of various lengths. Such a custom is also apparent among the Hamar of Ethiopia (Dubosson 2006, 2014).

History of modification of other body areas

Hard evidence that modifications of other body parts of cattle were done in prehistoric times by ancient African ethnic groups is difficult to obtain because soft tissue remains rarely endure at archaeological sites. However, Neolithic rock art in north-western African countries, such as Morocco (Searight 2004, 2013) and Niger (Fig. 8b, d), shows cattle with dewlap modifications comparable with that practiced by modern day Turkana on their favourite-oxen. Ear markings have not been recorded in ancient African rock art scenes, but this may simply be because drawing it represented technical challenges to Neolithic artists.

Conclusions

This article is embracing the interpretation of ethnoarcheology put forward by David and Kramer: “ethnoarcheology is neither a theory or method but a research strategy” that includes “a range of approaches to understanding the relationship of material culture to culture as a whole, both in the living context and as it enters the archaeological record, and to exploiting such understandings in order to inform archaeological concepts and to improve interpretation” (David and Kramer 2001: 2). This concept is more clearly summarized by the definition of the archeologist Lewis Binford: ethnoarchaeology is a “Rosetta stone: a way of translating the static material found on an archaeological site into the vibrant life of a group of people who in fact left them there” (Binford 1983: 24). Turkana cattle modifications - the creation of a favourite-ox - are powerful and very visible, representing a tool with which individual Turkana are able to establish and affirm a vast array of cultural and social relationships at individual and family levels and among the various clans. As stated by Barrett (Barrett 1998: 2), who studied the Turkana extensively, “man creates the identity of the animal and the animal gives identity to man”. Cattle represent the pivotal element of life for the Turkana, and it is logical that the favourite-ox is a chosen tool to express a Turkana’s personal concepts of beauty and his idealized “public persona”, in addition to his relationship to the world. The Turkana cattle-centered lifestyle is a classic example of people developing their visual aesthetic feelings through an easily available common object, which Gombrich terms “the marvel of everyday vision” (Gombrich 1977: 275 quoted by Coote 1992). It is undeniable that the Turkana favourite-ox coat patterns, horn deformations and body modifications are similar to cattle images present in numerous Neolithic rock art scenes from a broad range of geographical areas. Such a fact might help to better understand and interpret livestock images found in prehistoric rock art from a variety of African and European sites. More importantly, it can be argued that the Turkana’s favourite-ox is a present-day tool that allows anthropologists to understand better the systems of thought, values and aesthetic perceptions of long-vanished prehistoric pastoral societies that produced similar rock art images.
