A severely organised polytheism with one chief divinity, to whom all the others were in definite degrees subordinated, might evolve a monotheism. And in Babylonian literature we can mark certain tendencies making in this direction. One tablet contains an inscription proclaiming all the high gods to be forms of Marduk, Nergal the Marduk of war, Nebo the Marduk {188} of land.[188.1] That all the deities were mere forms or emanations of the Eternal might have been an esoteric doctrine of certain gifted minds, though it was difficult thus to explain away and to de-individualise the powerful self-asserting personality of Ishtar, for an attractive goddess-cult is always a strong obstacle to pure monotheism. A particular king might wish at times to exalt the cult of a particular god into a monotheistic ideal; the attempt was seriously made in Egypt and failed. It may have been seriously intended by King Rammannirari III. (B.C. 811-782), who introduced the cult of Nebo, always one of the most spiritual figures of the Pantheon, into Kelach; hence comes a long inscription on two statues now in the British Museum, set up by a governor in honour of the king, which is valuable for its ethical import, and still more interesting for its monotheistic exhortation at the close:[188.2] “Oh man, yet to be born, believe in Nebo, and trust in no other gods but him.” Here is the seed that might have been developed by a powerful prophet into pure monotheism. But the ecstatic Babylonian votary is always falling into contradiction, for in the earlier part of this hymn he has called Nebo, “The beloved of Bel, the Lord of Lords.” What, then, must the congregation think of Bel?
