Nephthys the sister and wife of Typhon, the evil god of the ancient Egyptians. To Osiris she bore Anubis, who is represented with the head of a dog. Nephthys belongs to the third order of deities, as classified by Sir J.G. Wilkinson in his Materia Hieroglyphica. In Egyptian theogony she personified the unfruitful earth, and was therefore the symbol of sterility.
Nephthys also represented the ocean, and hence it is possible that the god of the classic nations, Neptune, was derived from the Egyptians.
