Sammendrag
Between the sixth and ffteenth c. CE, a vast expanse of central and southern Sudan belonged to the kingdom of Alwa, ruled from the urban metropolis of Soba. Renewed investigation of the city unearthed a small cemetery in the northern part of the site. The heterogeneity of burial practices raised some questions as to the cultural and religious afnities of the deceased and suggested potential multiculturalism of the local urban population. We applied isotopic analyses to investigate the origins of the people buried at Cemetery OS and their concomitant ways of life. Non-concordance of 87Sr/86Sr and δ18O values with local hydro-geological background speaks to the mixing of water sources as a result of residential mobility. The concordance of human and faunal strontium and oxygen results, combined with elevated δ13C values corresponding to almost exclusive reliance on C4 produce, points to the possibility of seasonal movement of people with their herds between the Nile valley and the adjacent grasslands. Despite the turn of the medieval Nubian economy towards settled agriculture, by revealing the granular specificities of human adaptation in challenging ecosystems, our results produce the first insight into the enduring diversification of economic production, even in urbanized settings, and persisting participation of local peoples in agropastoral symbiosis.
