Pastoral rock art is the most common form of Central Saharan rock art, created in Cave painting and Petroglyph styles depicting pastoralists and bow-wielding hunters in scenes of animal husbandry, along with various animals (e.g., cattle, sheep, goats, dogs), spanning from 6300 BCE to 700 BCE. The Pastoral Period is preceded by the Round Head Period and followed by the Caballine Period. The Early Pastoral Period spanned from 6300 BCE to 5400 BCE. Domesticated cattle were brought to the Central Sahara (e.g., Tadrart Acacus), and given the opportunity for becoming socially distinguished, to develop food surplus, as well as to acquire and aggregate wealth, led to the adoption of a cattle pastoral economy by some Central Saharan hunter-gatherers of the Late Acacus.
The Middle Pastoral Period (5200 cal BCE – 3800 cal BCE) is when most of the Pastoral rock art was developed. In the Messak region of southwestern Libya, there were cattle remains set in areas in proximity to engraved Pastoral rock art depicting cattle (e.g., rituals of cattle sacrifice). Stone monuments are also often found in proximity to these engraved Pastoral rock art. A complete cattle pastoral economy (e.g., dairying) developed in the Acacus and Messak regions of southwestern Libya. Semi-sedentary settlements were used seasonally by Middle Pastoral peoples depending on the weather patterns (e.g., monsoon).
Amid the Late Pastoral Period, animals associated with the modern savanna decreased in appearance on Central Saharan rock art and animals suited for dry environments and animals associated with the modern Sahelian increased in appearance on Central Saharan rock art. At Takarkori, between 5000 BP and 4200 BP, Late Pastoral peoples herded goats, seasonally (e.g., winter), and began a millennia-long tradition of creating megalithic monuments, utilized as funerary sites where individuals were buried in stone-covered tumuli that were usually away from areas of dwellings in 5000 BP.
The Final Pastoral Period (1500 BCE – 700 BCE) was a transitory period from nomadic pastoralism toward becoming increasingly sedentary. Final Pastoral peoples were scattered, semi-migratory groups who practiced transhumance. Burial mounds (e.g., conical tumuli, v-type) were created set a part from others and small-sized burial mounds were created closely together. Final Pastoral peoples kept small pastoral animals (e.g., goats) and increasingly utilized plants. At Takarkori rockshelter, Final Pastoral peoples created burial sites for several hundred individuals that contained non-local, luxury goods and drum-type architecture in 3000 BP, which made way for the development of the Garamantian civilization.
Compared to painted Round Head rock art, in addition to its art production method, depictions of domesticated cattle are what makes engraved/painted Pastoral rock art distinct; these distinct depictions in the Central Sahara serve as evidence for different populations entering the region. The decreased appearance of large undomesticated organisms and increased appearance of one-humped camels and horses depicted in latter rock art (e.g., Pastoral, Camelline, Cabelline) throughout the Sahara serves as evidence for the Green Sahara undergoing increased desiccation.
Circular logic frequently serves as a basis for the intuitively reconstructed short chronology and long chronology. Nevertheless, a chronological Conceptual model that can provide explication of the complex nature of the Holocene and the Sahara (e.g., cultures, peoples), at-large, is ideal.
With the exception of a few instances, the common assumption is that Pastoral rock art corresponds with Pastoral Neolithic cultures, which remains largely unsubstantiated.
Due to its reliance on evidence of changes caused by windblown sand, which can vary depending on the area of rock that is exposed to it, the common use of patina to discern the age of a particular rock art style, such as engravings, can be viewed as rather undependable. In the case of Pastoral rock art, what may be more dependable is the likelihood that painted cattle, engraved cattle (which compose more than half of all engraved rock art), and pastoral motifs were composed by the same group of people. More work needs to be done to incorporate rock art styles that portray undomesticated animals (e.g., some dating after Pastoral rock art depicting cattle and some which may date before) into the existing chronological and cultural model.
More recently, black/dark patina, abundant in manganese, has been climatologically connected with the Green Sahara, connected with the engraving being performed before the development of the patina, and archaeologically connected with the Early Pastoral Period and before. Gray, light-colored patina, abundant in manganese, has been climatologically connected with the drying of the Green Sahara, connected with the engraving being performed amid the development of the patina, and archaeologically connected with the Middle Pastoral Period. Red patina, abundant in iron, is climatologically connected with a dry Sahara, connected with the engraving being performed after the development of the patina and before/amid mineral buildup, and archaeologically connected with the Late Pastoral Period and Final Pastoral Period. The absence of patina has been climatologically connected with a fully dry Sahara, too new for mineral buildup, and archaeologically connected with the Garamantian period and after.
A terminus post quem for the engraved rock art is established via evidence from archaeology for domesticated animals in the Central Sahara. Archaeological evidence for domesticated cattle is limited for the Early Pastoral Period (dated to the early 6th millennium BCE), increases to established cattle pastoral economy for the Middle Pastoral Period (dated to the 5th millennium BCE), and decreases by the Garamantian period (e.g., classical period, late period).
Patina containing an abundant amount of manganese underlie 53% of engraved animal rock art has been found at Wadi al-Ajal, which determines it to be probable that the engraved animal rock art (e.g., elephant, hartebeest, reedbuck, rhino) at Wadi al-Ajal were engraved amid, or even prior to, the Early Pastoral Period and the Middle Pastoral Period. At Wadi al-Ajal, there were ten scattered archaeological sites - nine sites from the Early Pastoral Period and Middle Pastoral Period as well as one site likely from the Pre-Pastoral Period. Numerous engraved Pastoral rock art of animals may reflect an increase in activity (e.g., increased utilization of natural resources) among pastoralists amid the Early Pastoral Period and Middle Pastoral Period.
Amid the Middle Pastoral Period, dairy farming and cattle grazing at pastures in the area of Wadi al-Ajal as well as transhumance between the southern region of the Messak and Wadi al-Ajal may have occurred.
Amid the Late Pastoral Period and Final Pastoral Period (3800 BCE – 1000 BCE), out of all of the engraved animal rock art, which included desert-adaptable animals (e.g., Barbary sheep, Ostriches), red-colored patina developed and underlay 33% of the engraved animal rock art at Wadi al-Ajal. Desertification availed new areas to creating Pastoral rock art that were previously unavailable in prior times.
Pastoral rock art is thought to portray Mediterranean and Sub-Saharan African peoples. Most rock art is thought to predominantly depict Mediterranean peoples and depict fewer Sub-Saharan African peoples by 4000 BP. However, other scholars have contested this as Joseph Ki-Zerbo argues this view reflected modern, racial theories which "give prominence to influences from outside Africa which are based on flimsy foundations" and rather all African physical types are reflected in the rock iconography.
Round Head rock art portrays human artforms with additional attributes (e.g., occasionally wielding bows, body designs, masks) and undomesticated animals (e.g., Barbary sheep, antelope, elephants, giraffes); the final period of the Round Head rock art portrayals have been characterized as Negroid (e.g., dominant mandible, big lips, rounded nose). Pastoral rock art, as distinct (e.g., technique, themes) from Round Head rock art, portrays situations from pastoral life and domesticated cattle; its portrayals have been characterized as Europoid (e.g., thin lips, pointed nose).
Some rock art from the Pastoral period seem to portray Africans with Caucasoid phenotypes residing among other African ethnic groups and also seem to portray some women with yellow-colored hair. While this may be the case, the uncertainty of whether or not the rock art portrayals actually reflect the phenotypic differences found among the African ethnic groups that occupied the region of ancient Libya has resulted in caution about the opinions formed regarding these rock art portrayals.
At Gobero, in Niger, Kiffian culture dwelled amid the early period of the Holocene and ceased doing so by 8500 BP; after one thousand years of vacancy, Tenerian culture began dwelling by 7500 BP; these phenotypically (e.g., tall and robust compared smaller and tiny) and culturally (e.g., hunter-gatherer compared to pastoralist) distinct peoples are viewed as being similar to what occurred in the Tadrart Acacus region of Libya and Tassili region of Algeria.
After having dwelled among one another in the Central Sahara, by 4000 BP, some of the hunter-gatherers, who created the Round Head rock art, may have associated with, admixed with, and adapted the culture of incoming cattle pastoralists.
In the Acacus region, at the Uan Muhuggiag rockshelter, there was a child mummy (5405 ± 180 BP) and an adult (7823 ± 95 BP/7550 ± 120 BP).
Neolithic agriculturalists, who may have resided in Northeast Africa and the Near East, may have been the source population for lactase persistence variants, including –13910*T, and may have been subsequently supplanted by later migrations of peoples. The Sub-Saharan West African Fulani, the North African Tuareg people, and European agriculturalists, who are descendants of these Neolithic agriculturalists, share the lactase persistence variant –13910*T. While shared by Fulani and Tuareg herders, compared to the Tuareg variant, the Fulani variant of –13910*T has undergone a longer period of haplotype differentiation. The Fulani lactase persistence variant –13910*T may have spread, along with cattle pastoralism, between 9686 BP and 7534 BP, possibly around 8500 BP; corroborating this timeframe for the Fulani, by at least 7500 BP, there is evidence of herders engaging in the act of milking in the Central Sahara.
Based on cattle remains near the Nile dated to 9000 BP and cattle remains near Nabta Playa and Bir Kiseiba reliably dated to 7750 BP, domesticated cattle may have appeared earlier, near the Nile, and then expanded to the western region of the Sahara. Though undomesticated aurochs are shown, via archaeological evidence and rock art, to have dwelled in Northeast Africa, aurochs are thought to have been independently domesticated in India and the Near East. After aurochs were domesticated in the Near East, cattle pastoralists may have migrated, along with domesticated aurochs, through the Nile Valley and, by 8000 BP, through Wadi Howar, into the Central Sahara.
The mitochondrial divergence of undomesticated Indian cattle, European cattle, and African cattle (Bos primigenius) from one another in 25,000 BP is viewed as evidence supporting the conclusion that cattle may have been domesticated in Northeast Africa, particularly, the eastern region of the Sahara, between 10,000 BP and 8000 BP. Cattle (Bos) remains may date as early as 9000 BP in Bir Kiseiba and Nabta Playa. While the mitochondrial divergence between Eurasian and African cattle in 25,000 BP can be viewed as supportive evidence for cattle being independently domesticated in Africa, introgression from undomesticated African cattle in Eurasian cattle may provide an alternative interpretation of this evidence.
Osypińska (2021) indicates that an "archaeozoological discovery made at Affad turned out to be of great importance for the entire history of cattle on the continent. A large skull fragment and a nearly complete horn core of an auroch, a wild ancestor of domestic cattle, were discovered at sites dating back 50,000 years and associated with the MSA. These are the oldest remains of the auroch in Sudan, and they also mark the southernmost range of this species in the world.
Indian humped cattle (Bos indicus) and North African/Middle Eastern taurine cattle (Bos taurus) are commonly assumed to have admixed with one another, resulting in Sanga cattle as their offspring. Rather than accept the common assumption, admixture with taurine and humped cattle is viewed as having likely occurred within the last few hundred years, and Sanga cattle are viewed as having originated from among African cattle within Africa. Regarding possible origin scenarios for Sub-Saharan African Sanga cattle, domesticated taurine cattle were introduced into North Africa, admixed with domesticated African cattle (Bos primigenius opisthonomous), resulting in offspring (the oldest being the Egyptian/Sudanese longhorn, some to all of which are viewed as Sanga cattle), or more likely, domesticated African cattle originated in Africa (including Egyptian longhorn), and became regionally diversified (e.g., taurine cattle in North Africa, zebu cattle in East Africa).
The managing of Barbary sheep may be viewed as parallel evidence for the domestication of amid the early period of the Holocene. Near Nabta Playa, in the Western Desert, between 11th millennium cal BP and 10th millennium cal BP, semi-sedentary African hunter-gatherers may have independently domesticated African cattle as a form of reliable food source and as a short-term adaptation to the dry period of the Green Sahara, which resulted in a limited availability of edible flora. African Bos primigenius fossils, which have been dated between 11th millennium cal BP and 10th millennium cal BP, have been found at Bir Kiseiba and Nabta Playa.
In the Western Desert, at the E-75-6 archaeological site, amid 10th millennium cal BP and 9th millennium cal BP, African pastoralists may have managed North African cattle (Bos primigenius) and continually used the watering basin and well and as water source. In the northern region of Sudan, at El Barga, cattle fossils found in a human burial serve as supportive evidence for cattle being in the area.
While this does not negate that it is possible for cattle from the Near East to have migrated into Africa, a greater number of African cattle in the same area share the T1 mitochondrial haplogroup and atypical haplotypes than in other areas, which provides support for Africans independently domesticating African cattle. Based on a small sample size (SNPs from sequences of whole genomes), African cattle split early from European cattle (Taurine). African cattle, bearing the Y2 haplogroup, form a sub-group within the overall group of taurine cattle. As a Near Eastern origin of African cattle requires a conceptual bottleneck to sustain the view, the diverseness of the Y2 haplogroup and T1 haplogroup do not support the view of a bottleneck having occurred, and thus, does not support a Near Eastern origin for African cattle. Altogether, these forms of genetic evidence provide the strongest support for Africans independently domesticating African cattle.
In the late period of the Pleistocene as well as the early and middle periods of the Holocene in West Africa and North Africa, peoples with Sudanese, Mechta-Afalou, and Proto-Mediterranean/Proto-Berbers skeletal types (which are outdated, problematic physical anthropological concepts) occupied these regions, and thus, occupied the Central Sahara (e.g., Fozziagiaren I, Imenennaden, Takarkori, Uan Muhuggiag) and Eastern Sahara (e.g., Nabta Playa). There are various types of stone constructions (e.g., Keyhole: 4300 BCE – 3200 BCE; Platform: 3800 BCE – 1200 BCE; Cone-Shaped: 3750 BCE; Crescent – 3300 BCE – 1900 BCE; Aligned Structures: 1900 BCE – Beginning of Islamic Period; Crater Tumulus: 1900 BCE – Beginning of Islamic Period) in Niger. At Adrar Bous, in Niger, the most common type (71.66%) of tumuli are platform tumuli; the second most common (16.66%) type of tumuli are cone-shaped tumuli. The earlier “black-face rock art style” of Tassili rock art has been viewed as sharing cultural affinity with the Fulani people. Proto-Berbers, who have been viewed as having migrated into the Central Sahara from Northeast Africa, have been associated with the latter “white-face rock art style” (e.g., pale-skinned figures, beads, long dresses, cattle, cattle-related activities) that emerged in Tassili N’Ajjer in 3500 BCE. In 3800 BCE, the most early of platform tumuli developed in the Central Sahara, which has been viewed as a cultural practice that was brought into the Central Sahara by Proto-Berbers. The inconsistencies within the view that Proto-Berbers migrated from Northeast Africa and brought the platform tumuli tradition into the Central Sahara is that the measurements for the skeletal types of the Central Sahara do not begin to match the skeletal types of Northeast Africa until after 2500 BCE and the constructing of platform tumuli at Adrar Bous, in Niger, began in 3500 BCE. In the Western Sahara, the pastoralist-associated hearths, pottery from the Late Neolithic, and the most common type of Western Saharan tumuli – cone-shaped tumuli (which emerged earliest in Niger by 3750 BCE and has connections with the Mediterranean), are probably associated with Protohistoric Berbers At Gobero, in Niger, the Tenerian culture that has been characterized as pastoral is based on only two cattle remnants and an absence of sheep/goat remnants; until the end of the mid-Holocene, there is limited evidence for nomadic lifeways; there is also anatomical evidence that is indicative of general population continuity amid the mid-Holocene at Gobero. The tumuli tradition of the Central Sahara likely developed as a result of interactions between culturally and ethnically different Central Saharan peoples (e.g., as depicted in Central Saharan rock art), within the context of changing and varied Central Saharan ecology. The traits (e.g., hierarchy, social complexity) of the earlier Central Saharan pastoral culture contributed to the latter development of state formation in West Africa, Nubia, and the Sahara.
In 10,000 BP, the Tropical Africa monsoon rain system from Sub-Saharan western Africa changed direction and moved northward into the Central Sahara. As the monsoon rain system moved northward into the Central Sahara, amid a period which brought along with the development of a savanna environment (akin to the savanna environments of contemporary Kenya, Tanzania, and Zimbabwe), egalitarian black African hunter-gatherers also migrated northward into the Central Sahara (e.g., Uan Muhuggiag rock shelter, Acacus Mountains, Libya). Later, in 7000 BP, pastoralists migrated into the Central Sahara, along with their pastoral animals (e.g., cattle, goats). The pastoralists may have migrated from the Near East (e.g., Mesopotamia, Palestine) and from the Eastern Sahara. Saharan pastoral culture spanned throughout northern Africa (e.g., Algeria, Chad, Egypt, Libya, Mali, Niger, Sudan), including in Niger where human burials, pottery, and rock art were found. At Uan Muhuggiag, the pastoral culture, which has been characterized as mixed race, may have begun earlier than 5500 BP. In the region, there were various kinds of flora (e.g., Typha) and fauna (e.g., hippopotamuses, crocodiles, elephants, lions, giraffe, gazelle). At the Uan Muhuggiag rock shelter, around 5600 BP, a two and a half year old Sub-Saharan African boy (determined through examination of the complete set of human remains, which included a Negroid skull and remnants of dark skin) was mummified (e.g., embalmed, Disembowelment – removal of organs from the abdomen, chest, and thorax, followed by replacement with organic preservatives to prevent decomposition, and wrapped in the skin of an antelope and leaves for insulation) utilizing advanced mummification methods. As the child mummy of Uan Muhuggiag was buried with a necklace made from ostrich eggshells, this may indicate that it was a compassionate, ceremonial burial relating to the afterlife. As the earliest dated mummy in Africa, the child mummy of Uan Muhuggiag may date at least one thousand years older than the mummies of ancient Egypt, and may belong to a Central Saharan mummification tradition that may date hundreds to thousands of years prior to the mummification of the child mummy of Uan Muhuggiag. At Mesak Settafet (e.g., Wadi Mathendous), there was engraved rock art depicting cattle and human forms with animal heads (e.g., jackal/dog masks) as well as a presence of cattle culture, and particularly, near a circularly arranged set of stone monuments, evidence of cattle being sacrificed and pottery given as ritual offering. In the Nile Valley region of Sudan, decorated Saharan pottery, which was dated to 6000 BP and stands in contrast to local pottery that were not decorated, was also found. As Central Saharan cattle pastoral culture emerged thousands of years earlier than when it reached its apex in the Nile Valley, Central Saharan pastoral culture produced the cultural motif of a human form wearing a jackal mask may date one thousand years earlier than 5600 BP (date based on tested organic material from rock shelter wall crevice) and appears one thousand years earlier than in the Nile Valley, and Central Saharan pottery was found in the Nile Valley, Central Saharan pastoral culture may have contributed to the latter development of ancient Egypt (e.g., decoration of pottery; cattle pastoralism; funerary culture and the mythological guardian of the dead and god of embalming, Anubis). Though the descendants of the people of Uan Muhuggiag may have vacated the region five hundred years after the embalming of the child of Uan Muhuggiag due to increasing aridification, and the occurrence of demic diffusion is possible, it is more likely that knowledge from the Central Saharan pastoral culture may have been transmitted into the Nile Valley through cultural diffusion in 6000 BP.
Pastoralism, possibly along with social stratification, and Pastoral rock art, emerged in the Central Sahara between 5200 BCE and 4800 BCE.
By at least 4th millennium BCE, as indicated via the painted rock art of Tassili n’Ajjer, Proto-Fulani culture may have been present in area of Tassili n’Ajjer. The Agades cross, a fertility amulet worn by Fulani women, may be associated with the hexagon-shaped carnelian piece of jewelry depicted in the rock art at Tin Felki. At Tin Tazarift, the depiction of a finger may allude to the hand of the mythic figure, Kikala, the first Fulani pastoralist. At Uan Derbuaen rockshelter of eastern Tassili, composition six may depict a white ox, under the spell of serpent-related animals, crossing through a U-shaped gate of vegetation, toward a powerful benevolent figure, in order to undo the spell on the ox. Composition six has been interpreted as portraying the Lotori ceremonial rite of Sub-Saharan West African Fulani herders. The annual Lotori ceremonial rite, held by Fulani herders, occurs at a selected location and period of time,
After migrating from the Central Sahara, by 4000 BP, the Mande peoples of West Africa established their agropastoral civilization of Tichitt Culture in the Western Sahara. The painted Pastoral rock art of Tassili n'Ajjer, Algeria and engraved Pastoral rock art of Niger bear resemblance (e.g., color markings of the cattle) with the engraved cattle portrayed in the Dhar Tichitt rock art in Akreijit.
At Takarkori rockshelter, Early Pastoral peoples utilized fireplaces between 7400 BP and 6400 BP. Early Pastoral peoples established a centuries-long burial tradition of utilizing rockshelters as special locations for burial of the dead (e.g., women, children), which, by the time of the Middle Pastoral peoples, ceased to be practiced. Early Pastoral peoples buried more of their dead in comparison to late Middle Pastoral peoples at least partly due to seasonal dwelling and possibly discovering earlier burials made by Early Pastoral peoples. Early Pastoral peoples buried their dead via stone-covered tumuli, where the entombed dead were covered in stones.
The Middle Pastoral Period (5200 cal BCE – 3800 cal BCE) is when most of the Pastoral rock art was developed. In the Messak region of southwestern Libya, there were cattle remains set in areas in proximity to engraved Pastoral rock art depicting cattle (e.g., rituals of cattle sacrifice). Stone monuments are also often found in proximity to these engraved Pastoral rock art. A complete cattle pastoral economy (e.g., dairying) developed in the Acacus and Messak regions of southwestern Libya. Semi-sedentary settlements were used seasonally by Middle Pastoral peoples depending on the weather patterns (e.g., monsoon). Wadi Bedis meander had 42 stone monuments (e.g., mostly corbeilles, stone structures and platforms, tumuli). Ceramics (e.g., potsherds) and stone implements were found along with 9 monuments bearing engraved rock art. From 5200 BCE to 3800 BCE, burial of animals occurred. Nine decorated ceramics (e.g., mostly rocker stamp/plain edge design, sometimes alternately pivoting stamp design) and sixteen stone maces were found. Some stone maces, used literally or symbolically to Ritual slaughter the cattle (e.g., Bos taurus), were ceremonially set near the head of sacrificed cattle or stone monuments. These ceremonies were shown across several centuries worth of excavated sites. Goats or hoofed animals were found as well. While the possible reason (e.g., appeal for rain, convey cultural identity, death, drying of the Sahara, initiation, marriage, transhumance) for the occurrence of cattle sacrificial ceremonies may not be able to verified, it may be the case that they occurred during events when distinct pastoral groups assembled together. Altogether, this has been characterized as being an African Cattle Complex.
At the Uan Muhuggiag rockshelter, the child mummy of Uan Muhuggiag has been radiocarbon dated, via the deepest coal layer where it was found, to 7438 ± 220 BP, and, via the animal hide it was wrapped in, to 5405 ± 180 BP,
At Takarkori rockshelter, Middle Pastoral peoples developed a completely cattle (Bos taurus) pastoralist-driven economic system (e.g., pottery, milking) between 6100 BP and 5100 BP. Middle Pastoral peoples, who occupied rockshelters seasonally, buried their dead in pits at varied depths. Thirteen human remains as well as two female human remains that had undergone incomplete, natural mummification were found at Takarkori rockshelter, which were dated to the Middle Pastoral Period (6100 BP – 5000 BP). More specifically, with regard to the mummies, one of the naturally mummified females was dated to 6090 ± 60 BP and the other was dated to 5600 ± 70 BP. These two naturally mummified females were the earliest dated mummies to undergo histological inspection. The two naturally mummified women carried basal haplogroup N.
In 5000 BP, the development of megalithic monuments (e.g., architecture) increased in the Central Sahara. In the Central Sahara, the tumuli tradition originated in the Middle Pastoral Period and transformed amid the Late Pastoral Period (4500 BP – 2500 BP).
