The royal cemetery of Umm el-Qa'ab near Abydos contains the tombs and funerary enclosures of First Dynasty rulers, dating back to around 3000 BC. Surrounding these structures are hundreds of subsidiary graves thought to belong to members of the royal household, including ladies, seal-bearers, inspectors and artisans.
Dr Roselyn Campbell of Purdue University in the US re-examined the skulls of 46 retainers from graves belonging to King Djer, King Djet and Queen Merneith. The skulls are held in the Duckworth Collections at the University of Cambridge.
The study found fractures consistent with perimortem trauma, supporting the view of English Egyptologist Flinders Petrie, who excavated the graves in the 1920s and believed the burials represented human sacrifice. However, Petrie found no evidence of trauma on the remains, leading some later experts to suggest the retainers died naturally and were reburied at Abydos when their ruler died.
Campbell noted in the study: "While Aha, the first ruler of the First Dynasty, seems to have only had a few subsidiary burials, his successors included hundreds of subsidiary graves around their tombs and enclosures."
The new findings provide the first clear osteological evidence that at least some of these individuals died violently at or around the time of the royal burial, strengthening the case for retainer sacrifice in early dynastic Egypt.
