Historians have pored over the remains and mystery of King Tut since the discovery of the long-deceased Egyptian Pharaoh in 1922, and a fresh theory sheds new light on why the ancient ruler was laid to rest in an unusual manner. In unscientific terms, Tut — short for Tutankhamun — was mummified with an erection, something American University in Cairo Egyptologist Salima Ikram now suggests was to let the dead ruler continue a religious campaign against his father. A new possibility, says Ikram, was to bury Tutankhamun as Osiris (Egypts god of the underworld), so that he could continue the effort in the afterlife.
