Amun was a major ancient Egyptian deity who appears as a member of the Hermopolitan Ogdoad. Amun was attested from the Old Kingdom together with his wife Amunet. His oracle in Siwa Oasis, located in Western Egypt near the Libyan Desert, remained the only oracle of Amun throughout. With the 11th Dynasty, Amun rose to the position of patron deity of Thebes by replacing Montu.
