Calypso (mythology)

In Greek mythology Calypso ("hidden" "hiding", also transliterated as Kalypso) was a sea nymph, daughter of Atlas, who delayed Odysseus on her dark and depressing island (Ogygia) for seven years.

Athena intervened and asked Zeus to order her to let him go. Zeus sent Hermes and Calypso reluctantly agreed. She had promised him immortality if he stayed. He left to be with his beloved Penelope. Calypso died in grief. With Odysseus, she was the mother of Nausinous.
