These two opposite principles did not come into immediate collision; the priests of heathendom laboured long and earnestly to avert such a catastrophe. In Greece they succeeded by transferring the mortal or changeable element from “the gods” to “the heroes.”[5] The human details in the characters and lives of Zeus and Apollon were transferred to the demi-gods or heroes represented as the sons or favourites of the gods. The two-fold character of Herakles as a god and a hero is recognized even by Herodotus; and indeed, some of the epithets applied to him sufficiently indicate his solar and originally divine personality. But to make some of the solar myths of which Herakles was the centre intelligible and conceivable, it became needful to depict Herakles as a mere human being, and to raise him to the seat of the Immortals only after he had endured toils and sufferings incompatible with the dignity of an Olympian divinity. In Peru the same treatment was adopted, but with different results. A thinking, or, as he was called, a free-thinking Inca, remarked that the sun’s perpetual travelling--he knew nothing, of course, of the Copernican theory--was a sign of servitude, and he threw doubts on the divine nature of aught so restless as the great luminary appeared to him to be. These doubts led to a tradition, which, even if unhistorical was not wholly untrue, that in Peru had existed an earlier worship--that of an Invisible Deity, the Creator of the World--Pachacamac. “In Greece, also, there are signs of a similar craving after the ‘Unknown God.’ A supreme God was wanted, and Zeus, the stripling of Creta, was raised to that rank. He became God above all gods--ἁπάντων κύριος, as Pindar calls him. Yet more was wanted than a mere Zeus; and then a supreme Fate or Spell was imagined before which all the gods, and even Zeus, had to bow. And even this Fate was not allowed to remain supreme, and there was something in the destinies of man which was called ὑπέρμορον or ‘beyond Fate.’ The most awful solution, however, of the problem belongs to Teutonic mythology. Here, also, some heroes were introduced; but their death was only the beginning of the final catastrophe. ‘All gods must die.’ Such is the last word of that religion which had grown up in the forests of Germany, and found a last refuge among the glaciers and volcanoes of Iceland. The death of Sigurd, the descendant of Odin, could not avert the death of Balder, the son of Odin, and the death of Balder was soon to be followed by the death of Odin himself, and of all the immortal gods.” Such a catastrophe was inevitable, so that Prometheus, the man of forethought, could safely predict the fall of Zeus.[6]
