Amun. He was sometimes depicted in the form of a goose which goes back to the myth about the 'Great Cackler'; the primeval goose whose shout was the first sound. There´s a varitey of the myth in which the primeval goose lays the 'world egg', and in another again, Amun fertilized this egg while in his form of Kematef, a ram-headed serpent. Wow, dow we now know a lot more about Amun! LOL!
