The creation tablets are written in Semitic and allude to the great circle of the gods as already fully developed and having its full complement. Even the later deities are mentioned in them. This means that it must be assigned to a comparatively late date, but it possesses elements which go to show that it is a late edition of a much earlier composition--indeed the fundamental elements in it appear, as has been said, to be purely Akkadian in origin, and that would throw back the date of its original form to a very primitive period indeed. It has, as will readily be seen, a very involved cosmogony. Its characteristics show it to have been originally local, and of course Babylonian, in its secondary origin, but from time to time it was added to, so that such gods as were at a later date adopted into the Babylonian pantheon might be explained and accounted for by it; but the legend of the creation arising in the city of Babylon, the local folk-tale known and understood by the people, was never entirely shelved by the more consequential and polished epic, which was perhaps only known and appreciated in literary and æsthetic circles, and bore the same relation to the humbler folk-story that Milton's _Paradise Lost_ bears to the medieval legends of the casting out of Satan from heaven. Although it is quite easy to distinguish influences of extreme antiquity in the Babylonian creation myth, it is clear that in the shape in which it has come down to us it has been altered in such a manner as to make Merodach reap the entire credit of Tiawath's defeat instead of En-lil, or the deity who was his predecessor as monarch of the gods. Jastrow holds that the entire cosmological tale has been constructed from an account of a conflict with a primeval monster and a story of a rebellion against Ea; that these two tales have become fused, and that the first is again divisible into three versions, originating one at Uruk and the other two at Nippur at different epochs. The first celebrates the conquest of Anu over Tiawath, the second exalts Ninib as the conqueror, and the third replaces him by En-lil. We thus see how it was possible for the god of a conquering or popular dynasty to have a complete myth made over to him, and how at last it was competent for the mighty Merodach of Babylon to replace an entire line of deities as the central figure of a myth which must have been popular with untold generations of Akkadian and Babylonian people.
