In the Heliopolitan Ennead cosmogony, he was considered to be the first god, having created himself, sitting on a mound (benben) (or identified with the mound itself), from the primordial waters (Nu). Early myths state that Atum created the god Shu and goddess Tefnut from his semen by masturbation in the city of Annu (the Egyptian name for Heliopolis)[1], a belief strongly associated with Atum's nature as an hermaphrodite (hence his name meaning completeness). Strictly, the myth states that Atum ejaculated his Semen into his mouth, impregnating himself, possibly indicating autofellatio, which has led many to misinterpret (Via euphemism or Bowdlerization) the myth as indicating creation from mucus.
