Calypso in Greek and Roman Biography and Mythology

（Καλυψώ). Under this name we find in Hesiod (Hes. Th. 359) a daughter of Oceanus and Tethys, and in Apollodorus (1.2.7) a daughter of Nereus, while the Homeric Calypso is described as a daughter of Atlas. (Od. 1.50.) This last Calypso was a nymph inhabiting the island of Ogygia, on the coast of which Odysseus was thrown when he was shipwrecked. Calypso loved the unfortunate hero, and promised him eternal youth and immortality if he would remain with her. She detained him in her island for seven years, until at length she was obliged by the gods to allow him to continue his journey homewards.
