Diodorus Siculus
And besides these there are other gods, they say, who were terrestrial, having once been mortals, but who, by reason of their sagacity and the good services which they rendered to all men, attained immortality, some of them having even been kings in Egypt. Their names, when translated, are in some cases the same as those of the celestial gods, while others have a distinct appellation, such as Helius, Cronus, and Rhea, and also the Zeus who is called Ammon by some, and besides these Hera and Hephaestus, also Hestia, and, finally, Hermes. [….]
Then Cronus became the ruler, and upon marrying his sister Rhea he begat Osiris and Isis, according to some writers of mythology, but, according to the majority, Zeus and Hera, whose high achievements gave them dominion over the entire universe. From these last were sprung five gods, one born on each of the five days which the Egyptians intercalates: the names of these children were Osiris and Isis, and also Typhon, Apollo, and Aphrodite. — 1.13
Osiris, they add, also built a temple to his parents, Zeus and Hera, which was famous both for its size and its costliness in general, and two golden chapels to Zeus, the larger one to him as god of heaven, the smaller one to him as former king and father of the Egyptians, in which role he is called by some Ammon. He also made golden chapels for the rest of the gods mentioned above, allotting honours to each of them and appointing priests to have charge over these. — 1.15
