Nephthys

Youngest of the five children of Nut and Geb, wife of Typhon (Set) and mother of Anubis by Osiris, who mistook her for Isis; with Isis she is the second of the two mourning sisters whose Lamentations were sung at the Osiris festival. Plutarch glosses her name as "Finality" and reads her as the barren land at the edge of the Nile flood.
