"There could be a simple explanation: the position in meridian alignment with the Step Pyramid was not free at all, being occupied by Userkare's complex," Magli said.
He suggested that Userkare's tomb is located approximately in the middle of the line connecting Pepi I and Merenre's diagonals, in alignment with Djoser's pyramid.
According to Egyptologist Vassil Dobrev, at the French Institute of Archaeology in Cairo, the suggestion makes sense on the satellite map, but is difficult to see on the field. Dobrev believes Userkare's tomb lie on a different, north-south diagonal in South Saqqara which would chronologically link the 6th Dynasty kings.
Indeed, he is excavating a 15-hectare area in Tabbet al-Guesh, where he has found several graves of priests from the 6th Dynasty.
Since the presence of a necropolis is a strong hint to a pyramid nearby, Dobrev believes Userkare's lies just there.
"These priest come to this place to serve the cult of a dead King. We do not have the name of Userkare yet, because the priests speak systematically about the 'King, their God.' They obviously refer to the dead King, whom everybody knew the name," Dobrev told Discovery News.
