Nephthys

Nephtys is one of the Egyptian Nine Ennead. She is daughter of Nut and Geb. Nephthys was typically paired with her sister Isis in funerary rites because of their role as protectors of the mummy and the god Osiris. She was the sister-wife of Set.

Nephthys plays an important role in the Osirian myth-cycle. It is Nephthys who assists Isis in gathering and mourning the dismembered portions of the body of Osiris, after his murder by the envious Set. Nephthys also serves as the nursemaid and watchful guardian of the infant Horus. The Pyramid Texts refer to Isis as the "birth-mother" and to Nephthys as the "nursing-mother" of Horus.
