As a rule, the subject of a Babylonian poem is either some single god or some single hero. When the god or hero is merely a central figure around whose adventures those of other gods or heroes are made to revolve, the poem becomes an Epic. It still retains its mythological shape, and the world in which it moves is a world of supernatural powers, a divine fairyland in which the gods play the part of men. But there is none of the dull and crass euhemerism which distinguishes the Egyptian tales of the gods. The gods do not become mere men with enlarged human powers; they remain divine, even though their actions are human and the stage on which they move is human also. It was the pantheism of the Egyptian, in conjunction with the deification of the Pharaoh, that made him rationalise the stories of his gods; in Babylonia there was no such temptation; each deity retained his individual character, and from the outset he had worn the likeness of a man. But it was a likeness only, behind which the divinity revealed itself, though the likeness necessarily caused the revelation to be made through individual features, clearly cut and sharply defined. Bel was no human king possessed of magical powers, who had once sat on the throne of Babylon; he remained the god who could, it is true, display himself at times to his faithful worshippers, but whose habitation was in the far-off heavens, from which he surveyed and regulated the actions of mankind. The gods of Babylonian mythology still belonged to heaven and not to earth, and its heroes are men and not humanised gods. I have already referred to the story of the first man, Adapa, and his refusal of the gift of immortality. The story, as we have it, has received a theological colouring; like the narrative of the Fall in the Book of Genesis, it serves to explain why death has entered the world. Man was made in the likeness of the gods, and the question therefore naturally arose why, like them, he should not be immortal. The answer was given, at any rate by the priests of Eridu, in the legend of Adapa and his journey to the sky.
