It is said that Boreas [the north wind
] carried off Oreithyia. Rather, he was king of the region to the north. The same assumption and approach can also be used for the story of Zeus and Ganymede. He was a king who carried off Ganymede, and he was said to have transformed into an eagle because it too is a formidable creature. The same can be said for Eos and Tithonos, and for Aphrodite and Anchises.
