The idea of space, too, must have assisted in such a conception as the residence of the gods in the upper regions of air. The earth would not be large enough for them, but the boundless vault above would afford them plenty of space in which to dwell. Again, the sun and moon being gods, it would be only natural for the other deities to dwell beside them, that is, in the 'heaven of Anu,' as the Babylonians called the sky. It has been suggested that the conception of a pantheon dwelling in the sky originated in theological processes forwarded by a school or priesthood, but there is no reason to suppose that this was so, and the possibilities are easily covered by the circumstances of the animistic theory. Planets identified with Gods Jupiter, the largest of the planets, was identified with Merodach, head of the Babylonian pantheon. We find him exercising control over the other stars in the creation story under the name Nibir. Ishtar was identified with Venus, Saturn with Ninib, Mars with Nergal, Mercury with Nabu. It is more than strange that gods with certain attributes should have become attached to certain planets in more countries than one, and this illustrates the deep and lasting influence which Semitic religious thought exercised over the Hellenic and Roman theological systems. The connexion is too obvious and too exact not to be the result of close association. There are, indeed, hundreds of proofs to support such a theory. Who can suppose, for example, that Aphrodite is any other than Ishtar? The Romans identified their goddess Diana with the patroness of Ephesus. There are, indeed, traces of direct relations of the Greek goddess with the moon, and she was also, like Ishtar, connected with the lower world and the sea. The Greeks had numerous and flourishing colonies in Asia Minor in remote times, and these probably assisted in the dissemination of Asiatic and especially Babylonian lore.
