Heaven itself had not always been 'the land of the silver sky' of later Assyrian belief. The Babylonians once believed that the gods inhabited the snow-clad peak of Rowandiz, 'the mountain of the world' and 'the mountain of the East,' as it was also termed, which supported the starry vault of heaven. It is to this old Babylonian belief that allusion is made in Isaiah xiv. 13, 14, where the Babylonian monarch is represented as saying in his heart: 'I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also on the mount of the assembly (of the gods)[4] in the extremities[5] of the north: I will ascend above the heights of the clouds.' [4] A. V. 'congregation.' [5] A. V. 'sides.' As in all old forms of heathen faith, religion and mythology were inextricably mixed together. Myths were told of most of the gods. Reference has already been made to the myth of Istar and Tammuz, the prototype of the Greek legend of Aphroditê and Adonis. So, too, the Greek story of the theft of fire by Prometheus has its parallel in the Babylonian story of the god Zu, 'the divine storm-bird,' who stole the lightning of Bel, the tablet whereon the knowledge of futurity is written, and who was punished for his crime by the father of the gods. In reading the legend of the plague-demon Lubara, whom Anu sends to smite the evildoers in Babylon, Erech, and other places, we are reminded of the avenging angel of God whom David saw standing with a drawn sword over Jerusalem. One of the most curious of the Babylonian myths was that which told how the seven evil-spirits or storm-demons had once warred against the moon and threatened to devour it. Samas and Istar fled from the lower sky, and the Moon-god would have been blotted out from heaven had not Bel and Ea sent Merodach in his 'glistening armour' to rescue him. The myth is really a primitive attempt to explain a lunar eclipse, and finds its illustration in the dragon of the Chinese, who is still popularly believed by them to devour the sun or moon when an eclipse takes place. The primæval victory of light and order over darkness and chaos, which seems to be repeated whenever the sun bursts through a storm-cloud, was similarly expressed in a mythical form. It was the victory of Merodach over Tiamat,'the deep,' the personification of chaos and elemental anarchy. The myth was embodied in a poem, the greater part of which has been preserved to us. We are told how Merodach was armed by the gods with bow and scimetar, how alone he faced and fought the dragon Tiamat, driving the winds into her throat when she opened her mouth to swallow him, and how, finally, he cut open her body, scattering in flight 'the rebellious deities' who had stood at her side. Tiamat, or the watery chaos, is usually represented with wings, claws, tail, and horns, but she is also identified with 'the wicked serpent' of 'night and darkness,' 'the monstrous serpent of seven heads,' 'which beats the sea.'
