"But if
he’s one of the deathless powers, out of the blue,
the gods are working now in strange, new ways.
Always, up to now, they came to us face-to-face
whenever we’d give them grand, glorious sacrifices."
– Homer
The Odyssey, Book 7, lines 234-238. Alcinous wonders if Odysseus might be a god. Up to now the gods used to come to them undisguised, he says.
