first, Enlil to the second, and Ea to the third zone. The astral theology of the Babylonian-Assyrian religion, while thus bearing the ear-marks of a system devised by the priests, succeeded in assimilating the beliefs which represented the earlier attempts to systematize the more popular aspects of the religion, and in this way a unification of diverse elements was secured that led to interpreting the contents and the form of the religion in terms of the astral-theological system. Ethic On the ethical sides, the religion of Babylonia more particularly, and to a less extent that of Assyria, advances to noticeable conceptions of the qualities associated with the Gods and Goddesses and of the duties imposed on man. Shamash, the Sun-God, was invested with justice as his chief trait, Marduk is portrayed as full of mercy and kindness, and Ea is in general the protector of mankind, a father who takes them under his protection. The Gods, to be sure, are easily aroused to anger, and in some of them the dire aspects predominated, but the view becomes more and more pronounced that there is some cause always for the divine wrath. Though, in accounting for the anger of the Gods, no sharp distinction is made between moral offences and a ritualistic oversight or neglect, yet the stress laid in the hymns and prayers, as well as in the elaborate atonement ritual prescribed in order to appease the anger of the Gods, on the need of being clean and pure in the sight of the higher powers, the inculcation of a proper aspect of humility, and above all the need of confessing one's guilt and sins without any reserve—all this bears testimony to the strength which the ethical factor acquired in the domain of the Religion. This factor appears to less advantage in the unfolding of the views concerning life after death. Throughout all periods of Babylonian-Assyrian history, the conception prevailed of a large dark cavern below the earth, not far from the Apsu—the fresh water abyss encircling and flowing underneath the earth—in which all the dead were gathered and where they led a miserable existence of inactivity, amid gloom and dust. Occasionally a favoured individual was permitted to escape from this general fate and placed in a pleasant island. It would appear also that the rulers were always singled out for divine grace, and in the earlier periods of the
