In consequence of the determinative prefix for a god or a goddess being, in the oldest form, a picture of an eight-rayed star, it has been assumed that Assyro-Babylonian mythology is, either wholly or partly, astral in origin. This, however, is by no means certain, the character for "star" in the inscriptions being a combination of three such pictures, and not a single sign. The probability therefore is, that the use of the single star to indicate the name of a divinity arises merely from the fact that the character in question stands for /ana/, "heaven." Deities were evidently thus distinguished by the Babylonians because they regarded them as inhabitants of the realms above--indeed, the heavens being the place where the stars are seen, a picture of a star was the only way of indicating heavenly things. That the gods of the Babylonians were in many cases identified with the stars and planets is certain, but these identifications seem to have taken place at a comparatively late date. An exception has naturally to be made in the case of the sun and moon, but the god Merodach, if he be, as seems certain, a deified Babylonian king, must have been identified with the stars which bear his name after his worshippers began to pay him divine honours as the supreme deity, and naturally what is true for him may also be so for the other gods whom they worshipped. The identification of some of the deities with stars or planets is, moreover, impossible, and if Êa, the god of the deep, and Anu, the god of the heavens, have their representatives among the heavenly bodies, this is probably the result of later development.[1] [1] If there be any historical foundation for the statement that Merodach arranged the sun, the moon, the planets, and the stars, assigning to them their proper places and duties--a tradition which would make him the founder of the science of astronomy during his life upon earth--this, too, would tend to the probability that the origin of the gods of the Babylonians was not astral, as has been suggested, but that their identification with the heavenly bodies was introduced during the period of his reign.
