But whence each of the gods came to be, or whether all had always been, and how they appeared in form, they did not know until yesterday or the day before, so to speak; for I suppose Hesiod and Homer flourished not more than four hundred years earlier than I; and these are the ones who taught the Greeks the descent of the gods, and gave the gods their names, and determined their spheres and functions, and described their outward forms. But the poets who are said to have been earlier than these men were, in my opinion, later. The earlier part of all this is what the priestesses of Dodona tell; the later, that which concerns Hesiod and Homer, is what I myself say.
