Long ago, Egyptians carved a cemetery into a rock wall along the Nile River 250 miles south of Cairo. The cemetery outlasted its 12th Dynasty creators. It survived intermittent pillaging by tomb raiders. And then in 1907, an excavator named Erfai discovered an untouched tomb. This was an unusual burial site. Within the tomb lay two high-society men, called Khnum-Nakht and Nakht-Ankh, their coffins adjacent.
