The Religion of Babylonia and Assyria

The old Babylonian moon-god plays a comparatively insignificant rôle in Assyria. Ashurnasirbal speaks of a temple that he founded in Calah—perhaps only a chapel—in honor of Sin. It could not have been of much importance, for we learn nothing further about it. Sargon, too, who manifests a great fondness for reviving ancient cults, erects sanctuaries to Sin along with a quantity of other gods in his official residence at Khorsabad and beyond the northeastern confines of Assyria at Magganubba. But when invoked by the kings, Sin shows traces of the influence which the conceptions current about Ashur exerted upon his fellow deities. He takes on, as other of the gods, the attributes of the war-god. Instead of being merely the lord of the crescent, as in Babylonia, and one of the sources of wisdom because of the connection of astrology with lunar observations, he is pictured as capable of inspiring terror. At the same time he is also the lord of plenty, and in his capacity as the wise god he is regarded as the lord of decisions. But by the side of new epithets that are attached to him in the Assyrian inscriptions, there is one which, just as in the case of Nin-ib, connects the Assyrian Sin cult with the oldest phase of moon-worship in the south. It is one of the last kings of Assyria, Ashurbanabal, who calls Sin 'the firstborn son of Bel.' He appears in this relationship to Bel in the religious texts of Babylonia.

The Bel here meant can only be the great god of Nippur, and the title 'son of Bel' accordingly shows that the moon-worship of Assyria is ultimately derived from that which had its seat in the south. Sin's secondary position is indicated by making him a son of Bel. The rise of the science of astronomy in connection with astrology, was, as already suggested, an important factor in spreading and maintaining the Sin cult in the south, while the lack of intellectual originality in Assyria would equally account for the comparatively subordinate position occupied by Sin in the Assyrian pantheon.
