Egyptian Nine Ennead

The Ennead was a group of nine deities in Egyptian mythology. The Ennead were worshipped at Heliopolis and consisted of the god Atum, his children Shu and Tefnut, their children Geb and Nut and their children Osiris, Isis, Set and Nephthys.

The creation account of Heliopolis relates that from the primeval waters represented by Nun, a mound appeared on which the self-begotten deity Atum sat. Bored and alone, Atum spat producing Shu, representing the air and Tefnut, representing moisture. Shu and Tefnut mated and brought forth Geb, representing the earth, and Nut, representing the nighttime sky. Because of their initial closeness, Geb and Nut engaged in continuous copulation until Shu separated them, lifting Nut into her place in the sky. The children of Geb and Nut were the sons Osiris and Set and the daughters Isis and Nephthys, which in turn formed couples.
