Nephthys is the sister of Osiris and Isis and the wife of Set. She is a very ancient goddess, first found in Old Kingdom writings. She is often depicted riding in the funeral boat accompanying the dead into the Blessed Land. She is not exactly the personification of death, but she is the closest thing to it in Egyptian belief. Though the wife of Set, she did not support him in his bid for power in the Osiris Legend. In fact, she does the opposite, aiding her sister Isis in finding the pieces of Osiris’ body. She is believed to be the mother of Anubis, and thus stands at the head of an entire family of funerary deities.
She is also revered as the head of the household of the gods, and her protection is given to the head woman of any house. In fact her name is given as a title to such women (literally translated it means “head of the house”). She also stands at the head of the bed to comfort women in childbirth while Bes dances.
