The Ennead, once created, was readily adopted by the other nomes of Egypt. It provided an easy answer to that first question of primitive humanity: what is the origin of the world into which we are born? The answer was derived from the experience of man himself; as he had been born into the world, so, too, it was natural to suppose that the world itself had been born. The creator must have been a father, and, in a land where the woman held a high place in the family, a mother as well. Though Tum continued to be pictured as a man, no wife was assigned him; father and mother in him were one. It is impossible not to be reminded of similar supreme gods in the Semitic kingdoms of Asia. Asshur of Assyria was wifeless;(56) so also was Chemosh of Moab. Nor does the analogy end here. Creation by generation was a peculiarly Semitic or rather Babylonian doctrine. The Babylonian Epic of the Creation begins by describing the generation of the world out of Mummu or Chaos. And the generation is by pairs as in the Ennead of Heliopolis. First, Mummu, the one primeval source of all things; then Lakhmu and Lakhamu, who correspond with Shu and Tefnut; next, Ansar and Kisar, the firmament and the earth; and lastly, the three great gods who rule the present world. Of one of these, Ea, the ruler of the deep, Bel-Merodach the sun-god was born. Between the Babylonian and the Egyptian schemes the differences are slight. In the Ennead of Heliopolis, Tum, the offspring of Nu, takes the place of Mummu, the watery chaos; but this was because he was the god of the State, and had therefore to be made the creator and placed at the head of the gods. It merely interposes another link in the chain of generation, separating Nu from the two elemental deities which in the Babylonian scheme proceeded immediately from it. For Nu was the exact equivalent of the Babylonian Mummu. Both denote that watery chaos out of which, it was believed, all things have come. And what makes the fact the more remarkable is, that though the conception of a primeval watery chaos was natural in Babylonia, it was not so in Egypt. Babylonia was washed by the waters of the Persian Gulf, out of which Ea, the god of the deep, had arisen, bringing with him the elements of culture, and the waves of which at times raged angrily and submerged the shore. But the Egyptians of history lived on the banks of a river and not by the sea; it was a river, too, whose movements were regular and calculable, and which bestowed on them all the blessings they enjoyed. So far from being an emblem of chaos and confusion, the Nile was to them the author of all good. I do not see how we can avoid the conclusion that between the Ennead of Heliopolis with its theory of cosmology, and the cosmological doctrines of Babylonia, a connection of some sort must have existed.(57)
