Tomb of Tausert and Setnakht - on the left Nephthys, the daughter of Nut, sister of Isis and wife of Seth, the god of disorder. Her loyalties, however, lay with Osiris, by whom she had a child, Anubis. When Seth found out who the father was, he murdered Osiris, and Nephthys joined Isis in the search for Osiris's body.
