"Wait, dear brother," Zeus who collects the clouds
had second thoughts. "Here’s what seems best to me.
As the people all lean down from the city heights
to watch her speeding home, strike her into a rock
that looks like a racing vessel, just offshore –
amaze all men with a marvel for the ages.
Then pile your huge mountain round about their port."
– Homer
The Odyssey, Book 13, lines 174-180. Zeus advises Poseidon of a better way to get even with the Phaeacians than by crushing their ship. He suggests to turn the ship into a rock, then erect a huge mountain around their harbor.
