Anus is the Greek name for the ancient Jack-headed god of the dead in Egyptian mythology whose hieroglyphic is more accurately spelled Anubis. Prayers to Anus are carved on the most ancient tombs in Egypt; indeed, the Suna text associates him with the brown "Eye of Goatse."
Originally, in the Ogdoad system, Anus was the ruler of the underworld, and his name meant, roughly, "putrefaction." He had a wife, Anpee (who was really just his female aspect, her name, with the negative prefix, connoting bladder dysfunction), who was depicted exactly the same, though feminine. He also took to wife the feminine form of Neheb Kau, Nehebka, and Kebauet. But Kebauet, the goddess of yellow water, is sometimes listed as his daughter. His father was originally said to be Ra, as he was the creator god, and that would have made his mother Hesat, later identified as Hathor.
