Yeah, Odysseus is on an island, held captive for seven years by the nymph Calypso. Calypso likes Odysseus. A lot. And she doesn't want him to leave. In the end, Athena asks Zeus for a favour and Hermes is sent to get Odysseus out of there. But it's all a bit hush hush, because Poseidon really hates Odysseus, but he's on holiday and can't interfere. And Odysseus is pretty sad about the whole trapped on the island thing:
But as for the great Odysseus -
Hermes could not find him within the cave.
Off he sat on a headland, weeping there as always,
wrenching his heart with sobs and groans and anguish,
gazing out over the barren sea through blinding tears.
The Odyssey, Book 5: Odysseus - Nymph and Shipwreck. Fagles translation, lines 91 - 95.
Calypso agrees to release Odysseus and helps him build a boat to get off the island. And Poseidon comes home from his party and smashes the boat up in a storm. So Odysseus is all wrecked again and washed up on shore.
