v.] There was also a manifest progress in the definition of the idea of God, that is, of a single infinite intelligence as the source and controlling power of phenomena.

We have it on record that in Peru this was the direct fruit of the myth of Viracocha.

It is related that the Inca Yupangui published to his people that to him had appeared Viracocha, with admonition that he alone was lord of the world, and creator of all things; that he had made the heavens, the sun, and man; and that it was not right that these, his works, should receive equal homage with himself.
Therefore, the Inca decreed that the image of Viracocha should thereafter be assigned supremacy to those of all other divinities, and that no tribute nor sacrifice should be paid to him, for He was master of all the earth, and could take from it as he chose.[1] This was evidently a direct attempt on the part of an enlightened ruler to lift his people from a lower to a higher form of religion, from idolatry to theism.

The Inca even went so far as to banish all images of Viracocha from his temples, so that this, the greatest of gods, should be worshiped as an immaterial spirit only.
