The theologians of a later day amused themselves by cataloguing the Sumerian names of the spirits invoked in the ancient incantations, and transforming them into titles of the deities of the official pantheon. The same process had been followed in the Semitic translations which were added to the incantatory texts. The spirit of the sun became Samas, the spirit of the evening star became Istar. En-lil of Nippur was transmuted into Bel, and Nin-lil, the lady of the ghost-world, into Bilat or Beltis. The process was facilitated by the changes undergone at Eridu by the magical texts themselves, even before the days of Semitic influence. Maritime intercourse with other lands had already deeply affected the theology of Eridu; the crude animism of an earlier epoch had made way for the conception of a culture-god who taught men the elements of civilisation, and wrote books for their instruction. He was still a “spirit” rather than a god in the Semitic sense of the word, but he was a spirit who had emerged above the rest, who had acquired those family ties which formed the very foundation of civilised life, and to whom the creation of the world was due. Ea was not indeed a Baal, but he was already on the way to become a god in human form. At the same time, both Ea and his son Asari still appear in animal shape. Asari is, it is true, “the benefactor of man,” but he is also “the mighty one of the princely gazelle,” and even “the gazelle” himself; while Ea is “the antelope of the deep,” or more simply “the antelope.”(315) At other times he is the “lord of the earth” which he has created, or the “king” of that “holy mound” of waters which rose up against the sky like a mountain, and behind which the sun appeared at dawn. The titles that he bears point unmistakably to Eridu. Here alone Ea was the creator of the earth, and here too, in the temple of the god, was a likeness of that “holy mound” whereon the future destinies of mankind were declared. The oldest incantations which have come down to us must have been composed at Eridu in the days of its Sumerian animism. There are other divine or semi-divine names in them which tell the same tale. The pure waters which heal the sick and destroy the power of witchcraft are brought by the water-spirit Nin-akha-kudda, “the mistress of spells,” whom the theologians of a later time transformed into a daughter of Ea. Bau, too, the heifer of the city of Isin,(316) appears along with the water-spirit. Like Zikum, she was the mother of Ea and “the generatress of mankind,” and she shared with Asari the honours of the New Year’s festival. But Bau, it would seem, was not originally from Eridu. She had come there from a neighbouring city, and her presence in the incantations is a proof that even in these oldest monuments of a sacred literature we are still far from the beginnings of Babylonian religion.
