Thousands of medieval Islamic tombs in eastern Sudan were arranged in hard-to-detect patterns, with sacred “parent” tombs hosting subclusters of emanating burials, according to archaeologists who studied the funerary monuments with a method designed for cosmology.
The team used satellite imagery to identify the locations of more than 10,000 monuments in the Kassala region of eastern Sudan. The monuments include tumuli, which are made of stone and are “relatively simple raised structures, widespread throughout African prehistory and history,” and “qubbas,” which is a term that referred to Islamic tombs and shrines in the pan-Arab world, a team of researchers wrote in a paper published July 7 in the journal PLOS One.
