The old faith was avenged, however, when Babylon became the political head of Babylonia. Ea was supplanted by his son, and the honours he had received were transferred to the younger god. It was his son, too, under a new and foreign name. Merodach was son of Ea only because he had been identified with Aṡari, who was son of Ea in the theology of Eridu. Henceforward Ea shines merely by reflected light. His wisdom is handed on to Merodach; even the creation of mankind is denied to him. It is not Ea, but Merodach, who conquers the dragon of chaos and introduces law and order into the world, and it is equally not Ea but Merodach who is the creator of all visible things. Ea is not robbed, like Bel of Nippur, of his name and prerogatives, he is simply effaced.[242]

Midway between Nippur and Eridu stood the city of Erech. Doubtless it was of Sumerian foundation, like the other great cities of Babylonia, but as far back as we can trace its history it is already a seat of Semitic power and religious cult. Its god was Anu, the sky. It may be that Anu had been brought from elsewhere, for a Babylonian inscription of the twelfth century b.c. calls Dêr rather than Erech his city; but if so, the Semitic inhabitants of Erech knew nothing of it. For them Anu was the protecting god of their city, the father of Istar, whose habitation it was. From the days when Erech first became a Semitic possession, Anu and Istar had been worshipped in it side by side. Indeed, it would seem from the inscription of Lugal-zaggi-ṡi, discovered at Nippur, that at the remote period to which it belongs Istar had not yet been associated with Anu in the divine government of Erech. Lugal-zaggi-ṡi was king of Erech, and as a consequence “priest of Ana,” but not of Istar. So far as the evidence goes at present, it points to the fact that the divine patron of Erech was Anu, and that Istar was introduced by the Semites, perhaps from the town of Dilbat (now Dillem).

The god and his name were alike borrowed by the Semite from his Sumerian predecessor. Ana was the Sumerian word for “sky,” and it was doubtless a spirit of the sky which had been worshipped by the primitive population of the country. But when the hieroglyphic pictures were first invented, out of which the cuneiform characters afterwards developed, the spirit was already on the way to becoming a god. The eight-rayed star which denotes Ana in the historical days of Babylonia [pg 309] also denotes a god. He thus became a type of the god as distinguished from the spirit, and bears witness to the evolution that was already taking place in the religion of Babylonia.

That there had been spirits of the sky, however, as well as spirits of the earth, was never forgotten. By the side of the Anunna-ki or “spirits of the earth” the later theology continued to retain a memory of the Igigi or spirits of heaven.[243] As En-lil was the chief among the spirits of the earth, so it is probable that Ana was chief among the spirits of the sky. But there was not the same difficulty in accommodating his name and personality to the new conception of a god that there was in the case of En-lil. His old Sumerian title brought with it no associations with animism; there was no need to change it, and it could therefore, like the name of Ea, be retained even when the spirit of the sky had become the god of heaven. From the outset Ana had stood outside the sphere and dominion of En-lil; he was no ghost of the underworld to be degraded or renamed.

While, therefore, in En-lil of Nippur, even under his new Semitic form of Bel, the dominant element remained Sumerian, and in Ea of Eridu the Semitic and Sumerian elements were mingled together, Ana of Erech was distinctively [pg 310] a Semitic god. It was only by main force, as it were, that En-lil could be transformed into the semblance of a Semitic Baal; up to the last he continued to be lord of the earth rather than of the sky, whose dwelling-place was below rather than above.[244] It was this, perhaps, which facilitated his effacement by Merodach; the lineaments of a Baal were more easily traceable in the sun-god of Babylon than in the god of Nippur. But the sky-god was already a Baal. Between him and the Semitic Baal-shamain, “the lord of heaven,” the distance was but slight, and it was not difficult to clothe him with the attributes which the Semite ascribed to his supreme deity. A consciousness of the fact may possibly be detected in the readiness with which the name and worship of Anu were accepted in the Semitic West; when Babylonian culture made its way to Canaan, it was primarily Anu and the divinities most closely associated with him—Istar, Anat, and Dagon—who found there a home.

Ana, the sky, thus became Anu, the god of a Semitised Babylonia. But a Semitised Babylonia could not conceive of a god without a goddess who stood to him in the relation of the feminine to the masculine gender. Out of Anu was formed Anat, the feminine counterpart of the god. The same process at Nippur had created a Belit or Beltis out of the masculine Bel. The goddesses owed their existence to a grammatical necessity, and their unsubstantial and colourless character justified their origin. They fitly represented the relation in which, according to Semitic ideas, the woman stood to the man. [pg 311] She was formed out of him in nature as the feminine was out of the masculine in language, and her very existence thus depended on her “lord.”

There was, indeed, a goddess, even in Erech, the centre of Semitic influence, who possessed a very strongly-marked and independent character of her own. This was Istar, of whom I shall have to speak at a future time. But it was just because Istar possessed this independent character that she could not be the wife of the god of the sky. The Semitic Baal brooked the presence of no independent goddess in the divine family; the wife of the god could not claim rights of her own any more than the wife of the man. Anu, like Bel and Ea, stood alone.

Erech had been made the capital of a temporarily united Babylonia at an early age in its Semitic history. Before the days of Sargon of Akkad, Lugal-zaggi-ṡi—we know him only by his Sumerian name—had made himself supreme over the smaller States of the country, and even carried his arms to the distant West. In an inscription he has left us he boasts that his empire extended “from the lower sea of the Tigris and Euphrates to the upper sea,” presumably the Mediterranean, as he further defines his power as stretching “from the rising to the setting of the sun.” Erech became the capital of the kingdom, and it was perhaps at this time that it acquired the name which it bore ever afterwards of “the city” par excellence. Future ages were never allowed to forget that it had once been the premier city of Babylonia.

Lugal-zaggi-ṡi calls himself “the priest of Anu,” the god of the city which he had made the seat of his power. Anu for awhile was the god of the supreme State in Babylonia, and therefore supreme god of the whole country. The king, it is true, had come from the north, [pg 312] and his authority had been given him by Bel of Nippur; the old sanctuary of Nippur still claimed the first place in the religion of Northern Babylonia, and the cult of its god retained its ancient hold on the veneration of the people. But from henceforward he had to share his divine honours with another; Bel of Nippur, indeed, conferred the sovereignty, but the sovereign was priest and vicegerent of Anu. Bel and Anu were associated together at the head of the pantheon of Northern Babylonia, and the position they occupied in it became more and more unique.

So firmly established was it before the reign of Sargon of Akkad, that even his victories and the empire he founded failed to give them a colleague in the god of the new capital city. Bel and Anu remained supreme; the sun-god of Akkad or Sippar had to content himself with a subordinate rank. The theological system which put Bel and Anu at its head was already formed, and the position assigned to them by the veneration and traditions of antiquity was too firmly fixed to be shaken. Northern Babylonia worshipped a dyad in the shape of two supreme gods.
