Satellite survey maps 280 stone burial enclosures of ancient cattle herders in Sudan
Only about 20 of the circular tombs in the Atbai Desert were known before; they were built between about 4500 and 2500 BC as the Sahara dried.
Peer-reviewed paper
Atbai Desert, Eastern Sudan Archaeologists working from satellite images have mapped 280 stone burial enclosures in the Atbai Desert of eastern Sudan. Cattle-herding communities probably built them between about 4500 and 2500 BC. Earlier fieldwork had recorded about 20 of the monuments. Nobody had studied them as one regional tradition.
The new study is published in African Archaeological Review. It groups the monuments under the name Atbai Enclosure Burials, or AEBs. The work is part of the Atbai Survey Project. The paper's authors include J. Cooper, M. Bourgeois and M. Crépy.
The Atbai lies between the Nile and the Red Sea Hills. That puts it between the well-studied worlds of ancient Egypt and Nubia. Archaeologists still know relatively little about the people who lived there.
Stone circles up to 82 metres across
The monuments are spread over a large area, from Upper Egypt to the Eritrean borderlands. There is a major cluster in the Upper Wadi Gabgaba region. Most are circular stone walls with burials inside. Their diameters range from 5 to 82 metres.
Some are closed circles; others have a single entrance. A few contain compound circles, or a central grave surrounded by animal burials.
The researchers think the enclosures needed organised communal labour. They took an average enclosure, about 60 metres in circumference. One person would have needed more than 160 eight-hour workdays to build it, they estimate. A group of 50 workers could have finished the job in a little over three days.
Cattle dominate the graves
Earlier fieldwork excavated enclosures at Wadi Khashab, Wadi el-Ku and Bir Asele. They held human remains together with the bones of cattle, sheep and goats. At Wadi Khashab, burials of cattle and sheep surrounded a central human burial. One of the largest monuments held about 18 cattle graves.
Sheep appear at several sites, but cattle dominate the funerary record. The team describes the society as strongly cattle-centred. Engravings and paintings in the region's rock art also show many cattle.
In several enclosures, one central burial dominates the layout. Other human and animal burials are arranged around it. The authors read this as a sign of emerging social inequality. They interpret it cautiously. The central person may have been a leader, an elder, a ritual specialist, an ancestor or someone else of unusual importance.
Burials that pair people with cattle are known elsewhere in north-eastern Africa from at least the sixth millennium BC. Links between elite burials and cattle are also known from Nubian cemeteries such as Qustul. The study does not attribute the Atbai monuments to Egyptians or to any single known Nubian culture.
Built near water as the Sahara dried
The tombs are not spread evenly across the desert. Many were built near wadis, former water sources, wells, rock pools or ground that would have supported pasture. The researchers take this as evidence of mobile herders. These herders moved their cattle between seasonal grazing and watering places.
Radiocarbon dates and earlier excavations suggest the monuments were built between 4500 and 2500 BC. That makes the earliest of them older than Egypt's pyramids. This was the end of the African Humid Period. In that long wet phase, much of the Sahara held grassland, lakes and seasonal rivers.
The study connects the rise of the burial tradition with the southward shift of the Intertropical Convergence Zone. That shift changed monsoon rainfall across the Sahara. At the time, the Atbai still had more vegetation and seasonal water than it does today.
The authors suggest the Atbai may have been a refuge as the land dried. There, cattle herders held on longer than in other parts of the Sahara. Later pastoralists appear to have relied more on sheep, goats and eventually camels. These animals cope better with arid conditions. In the end, shrinking water supplies forced the communities to leave.
Monuments lost to erosion and gold mining
The team notes that some monuments may have been lost. Erosion, flooding and modern gold mining have damaged parts of the desert. The researchers say more burial sites may once have existed.
Illegal and unregulated gold mining, with heavy machinery and looting, still threatens many of the enclosures. These include many of the sites the satellite survey recorded.
