"Our guest just in from abroad, the man is raving!
Quick, my boys, hustle him out of the house,
into the meeting grounds, the light of day –
everything here he thinks is dark as night!"

– Homer

The Odyssey, Book 20, lines 401-404. Eurymachus laughs at Theoclymenus’ warning to the suitors about terrifying omens involving blood and ghosts and death. He says mockingly that the seer is raving.
