We’d scarcely put that island astern when suddenly
I saw smoke and heavy breakers, heard their booming thunder.
The men were terrified – oarblades flew from their grip,
clattering down to splash in the vessel’s wash.
She lay there, dead in the water.

– Homer

The Odyssey, Book 12, lines 218-222. Having made their escape from the Sirens, Odysseus and his crew sail into new danger with big breakers and smoke appearing before them. The men drop their oars in terror at the thunder of the monster whirlpool Charybdis.
