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.
