Pharaoh Sekhemkhet smites an Asiatic prisoner. Carved on a high cliff above Wadi Maghara, this relief is a near duplicate of another found just 115 feet away. Nearby, at Serabit el-Khadem, the Pharaoh’s miners toiled to extract precious blue turquoise. Sekhemkhet, far left, wears the crown of Upper Egypt. The other two standing figures also depict this Pharaoh, who reigned from 2648 to 2642 B.C. In the center depiction, Sekhemkhet wears the crown of Lower Egypt with the long feather curling forward.
