Babylon itself came to be recognized as the real centre of the entire Euphrates valley.
Associated with Marduk was his consort Sarpanit, and grouped around the pair as princes around a throne were the chief deities of the older centres, like Ea and Damkina of Eridu, Nebo and Tashmit of Borsippa, Nergal and Allatu of Kutha, Shamash and Ā of Sippar, Sin and Ningal of Ur, as well as pairs like Ramman (or Adad) and Shala whose central seat is unknown to us. In this process of accommodating ancient prerogatives to new conditions, it was inevitable that attributes belonging specifically to the one or the other of these gods should have been transferred to Marduk, who thus from being, originally, a solar deity becomes an eclectic power, taking on the traits of Bel, Ea, Shamash, Nergal, Adad and even Sin (the moon-god)—a kind of composite residuum of all the chief gods.
In the religious literature this process can be traced with perfect definiteness. The older incantations, associated with Ea, were re-edited so as to give to Marduk the supreme power over demons, witches and sorcerers: the hymns and lamentations composed for the cult of Bel, Shamash and of Adad were transformed into paeans and appeals to Marduk, while the ancient myths arising in the various religious and political centres underwent a similar process of adaptation to changed conditions, and as a consequence their original meaning was obscured by the endeavour to assign all mighty deeds and acts, originally symbolical of the change of seasons or of occurrences in nature, to the patron deity of Babylon—the supreme head of the entire Babylonian pantheon. Besides the chief deities and their consorts, various minor ones, representing likewise patron gods of less important localities and in most cases of a solar character were added at one time or the other to the court of Marduk, though there is also to be noted a tendency on the part of the chief solar deity, Shamash of Sippara, and for the chief moon-god to absorb the solar and lunar deities of less important sites, leading in the case of the solar gods to the differentiation of the functions of Shamash during the various seasons of the year and the various times of the day among these minor deities. In this way Ninib, whose chief seat appears to have been at Shirgulla (Lagash), became the sun-god of the springtime and of the morning, bringing joy and new life to the earth, while Nergal of Kutha was regarded as the sun of the summer solstice and of the noonday heat—the harbinger of suffering and death.
There were, however, two deities who appear to have retained an independent existence—Anu (q.v.), the god of heaven, and Ishtar (q.v.), the great mother-goddess, who symbolized fertility and vitality in general. There are some reasons for believing that the oldest seat, and possibly the original seat, of the Anu cult was in Erech, as it is there where the Ishtar cult that subsequently spread throughout Babylonia and Assyria took its rise. While Anu, with whom there was associated as a pale reflection a consort Antum, assigned to him under the influence of the widely prevalent view among the early Semites which conceived of gods always in pairs, remained more or less of an abstraction during the various periods of the Babylonian-Assyrian religion and taking little part in the active cult of the temples, his unique position as the chief god of the highest heavens was always recognized in the theological system developed by the priests, which found an expression in making him the first figure of a triad, consisting of Anu, Bel and Ea, among whom the priests divided the three divisions of the universe, the heavens, the earth with the atmosphere above it, and the watery expanse respectively.
Postponing the discussion of this triad, it is to be noted that the systematization of the pantheon after the days of Khammurabi did not seriously interfere with the independence of the goddess Ishtar. While frequently associated with Marduk, and still more closely with the chief god of Assyria, the god Assur (who occupies in the north the position accorded to Marduk in the south), so much so as to be sometimes spoken of as Assur’s consort—the lady or Belit par excellence—the belief that as the source of all life she stands apart never lost its hold upon the people and found an expression also in the system devised by the priests. By the side of the first triad, consisting of Anu, Bel and Ea—disconnected in this form entirely from all local associations—we encounter a second triad composed of Shamash, Sin and Ishtar. As the first triad symbolized the three divisions of the universe—the heavens, earth and the watery element—so the second represented the three great forces of nature—the sun, the moon and the life-giving power. According as the one or the other aspect of such a power is brought into the foreground, Ishtar becomes the mother of mankind, the fertile earth, the goddess of sexual love, and the creative force among animals, while at times she appears in hymns and myths as the general personification of nature.
We thus find in the post-Khammurabic period the pantheon assuming distinct shapes. The strong tendency towards concentrating in one deity—Marduk—the attributes of all others was offset by the natural desire to make the position of Marduk accord with the rank acquired by the secular rulers. As these emphasized their supremacy by grouping around them a court of loyal attendants dependent in rank and ready to do their master’s bidding, so the gods of the chief centres and those of the minor local cults formed a group around Marduk; and the larger the group the greater was the reflected glory of the chief figure. Hence throughout the subsequent periods of Babylonian history, and despite a decided progress towards a monotheistic conception of divine government of the universe, the recognition of a large number of gods and their consorts by the side of Marduk remained a firmly embedded doctrine in the Babylonian religion as it did in the Assyrian religion, with the important variation, however, of transferring the rôle of the head of the pantheon from Marduk to Assur. Originally the patron god of the city of Assur (q.v.), when this city became the centre of a growing and independent district, Assur was naturally advanced to the same position in the north that Marduk occupied in the south. The religious predominance of the city of Babylon served to maintain for Marduk recognition even on the part of the Assyrian rulers, who, on the political side likewise, conceded to Babylonia the form at least of an independent district even when, as kings of Assyria, they exercised absolute control over it. They appointed their sons or brothers governors of Babylonia, and in the long array of titles that the kings gave themselves, a special phrase was always set aside to indicate their mastery over Babylonia. “To take the hand of Bel-Marduk” was the ceremony of installation which Assyrian rulers recognized equally with Babylonians as an essential preliminary to exercising authority in the Euphrates valley. Marduk and Assur became rivals only when Babylonia gave the Assyrians trouble; and when in 689 B.C. Sennacherib, whose patience had been exhausted by the difficulties encountered in maintaining peace in the south, actually besieged and destroyed the city of Babylon, he removed the statue of Marduk to Nineveh as a symbol that the god’s rule had come to an end. His grandson Assur-bani-pal, with a view of re-establishing amicable relations, restored the statue to the temple E-Saggila in Babylon and performed the time-honoured ceremony of “taking the hand of Bel” as a symbol of his homage to the ancient head of the Babylonian pantheon.
But for the substitution of Assur for Marduk, the Assyrian pantheon was the same as that set up in the south, though some of the gods were endowed with attributes which differ slightly from those which mark the same gods in the south. The warlike nature of the Assyrians was reflected in their conceptions of the gods, who thus became little Assurs by the side of the great protector of arms, the big Assur. The cult and ritual in the north likewise followed the models set up in the south. The hymns composed for the temples of Babylonia were transferred to Assur, Calah, Harran, Arbela and Nineveh in the north; and the myths and legends also wandered to Assyria, where, to be sure, they underwent certain modifications. To all practical purposes, however, the religion of Assyria was identical with that practised in the south.
We thus obtain four periods in the development of the Babylonian-Assyrian religion: (1) the oldest period from
