Homer’s
Odyssey. Odysseus’s ship is wrecked and he is washed ashore, clinging to a spar, on the island of Ogygia, where he is held captive and seduced by the nymph Calypso. Although she gives him everything he might be supposed to desire, the hero spends most of his time bemoaning his fate and proclaiming his homesickness for his native land. On the orders of the gods he is given the chance to build a raft of tree trunks and take to the sea. Poseidon sends fierce storms to test him, but his courage does not fail and, after twenty days, he reaches the land of the Phaeacians. See
Odyssey, book 5.
