In all their great undertakings they had recourse to the oracle; by that was decided the most important affairs between town and town, or province and province. The manner in which the oracles were rendered was not everywhere the same. It is said[180] the bull Apis, whose worship was anciently established in Egypt, gave out his oracles on his receiving food from the hand of him who consulted. If he received it, say they, it was considered a good omen; if he refused it, this was a bad augury. When this animal appeared in public, he was accompanied by a troop of children, who sang hymns in his honor; after which these boys were filled with sacred enthusiasm, and began to predict future events. If the bull went quietly into his lodge, it was a happy sign;[181] if he came out, it was the contrary. Such was the blindness of the Egyptians. There were other oracles also in Egypt:[182] as those of Mercury, Apollo, Hercules, Diana, Minerva, Jupiter Ammon, &c., which last was consulted by Alexander the Great. But Herodotus remarks that in his time there were neither priests nor priestesses who uttered oracles. They were derived from certain presages, which they drew by chance, or from the movements of the statues of the gods, or from the first voice which they heard after having consulted. Pausanias says[183] that he who consults whispers in the ear of Mercury what he requires to know, then he stops his ears, goes out of the temple, and the first words which he hears from the first person he meets are held as the answer of the god. The Greeks acknowledge that they received from the Egyptians both the names of their gods and their most ancient oracles; amongst others that of Dodona, which was already much resorted to in the time of Homer,[184] and which came from the oracle of Jupiter of Thebes: for the Egyptian priests related that two priestesses of that god had been carried off by Phoenician merchants, who had sold them, one into Libya and the other into Greece.[185] Those of Dodona related that two black doves had flown from Thebes of Egypt--that the one which had stopped at Dodona had perched upon a beech-tree, and had declared in an articulate voice that the gods willed that an oracle of Jupiter should be established in this place; and that the other, having flown into Lybia, had there formed or founded the oracle of Jupiter Ammon. These origins are certainly very frivolous and very fabulous. The Oracle of Delphi is more recent and more celebrated. Phemonoe was the first priestess of Delphi, and began in the time of Acrisius, twenty-seven years before Orpheus, Musaeus, and Linus. She is said to have been the inventress of hexameters.
