The Histories · 2.83

Their divination is ordered thus:—the art is assigned not to any man, but to certain of the gods, for there are in their land Oracles of Heracles, of Apollo, of Athene, of Artemis, of Ares, and of Zeus, and moreover that which they hold most in honour of all, namely the Oracle of Leto which is in the city of Buto. The manner of divination however is not yet established among them according to the same fashion everywhere, but is different in different places.
