Calypso

The Titan Atlas daughter was a sea-nymph and lived on the island Ogygia. She delayed Odysseus by seven years on his journey home to Itaca holding him and his men on the island. Odysseus was her lover, but eventually left in spite of the nymph's promises of immortality.

When Odysseus enemy Poseidon was away, Athena persuaded Zeus to help, and thus the god sent Hermes to Calypso with a message to let the hero go. Calypso even helped him with materials and information. After Odysseus left she died of a broken heart.
