They've landed on the wrong island, haven't they. Circe has plans of her own.
She ushered them in to sit on high-backed chairs,
then she mixed them a potion - cheese, barley
and pale honey mulled in Pramnian wine -
but into the brew she stirred her wicked drugs
to wipe from their memories any thought of home.
Once they'd drained the bowls she filled, suddenly
she struck with her wand, drove them into her pigsties,
all of them bristling into swine - with grunts,
snouts - even their bodies, yes, and only
the men's minds stayed steadfast as before.
So off they went to their pens, sobbing, squealing
as Circe flung them acorns, cornel nuts and mast,
common fodder for hogs that root and roll in mud.
The Odyssey, Book 10: The Bewitching Queen of Aeaea. Fagles translation, lines 256 - 268.
Odysseus has to go in and get his boys back. Circe eventually helps them on their way, but breaks the bad news - they have to go into the Underworld first.
