Herakles tries to see Zeus-Ammon
The Thebans, and those who by the Theban example will not touch sheep, give the following reason for their ordinance: they say that Heracles wanted very much to see Zeus and that Zeus did not want to be seen by him, but that finally, when Heracles prayed, Zeus contrived to show himself displaying the head and wearing the fleece of a ram which he had flayed and beheaded. It is from this that the Egyptian images of Zeus have a ram’s head; and in this, the Egyptians are imitated by the Ammonians, who are colonists from Egypt and Ethiopia and speak a language compounded of the tongues of both countries. It was from this, I think, that the Ammonians got their name, too; for the Egyptians call Zeus “Amon”. The Thebans, then, consider rams sacred for this reason, and do not sacrifice them. But one day a year, at the festival of Zeus, they cut in pieces and flay a single ram and put the fleece on the image of Zeus, as in the story; then they bring an image of Heracles near it. Having done this, all that are at the temple mourn for the ram, and then bury it in a sacred coffin. — 2.42
Oracle of Dodona came from Egypt
The priests of Zeus of Thebes told me that two priestesses had been carried away from Thebes by Phoenicians; one, they said they had heard was taken away and sold in Libya, the other in Hellas; these women, they said, were the first founders of places of divination in the aforesaid countries. When I asked them how it was that they could speak with such certain knowledge, they said in reply that their people had sought diligently for these women, and had never been able to find them, but had learned later the story which they were telling me. That, then, I heard from the Theban priests; and what follows, the prophetesses of Dodona say: that two black doves had come flying from Thebes in Egypt, one to Libya and one to Dodona; the latter settled on an oak tree, and there uttered human speech, declaring that a place of divination from Zeus must be made there; the people of Dodona understood that the message was divine, and therefore established the oracular shrine. The dove which came to Libya told the Libyans (they say) to make an oracle of Ammon; this also is sacred to Zeus.”– 2.54-55
