<P> Calypso is generally said to be the daughter of the Titan Atlas and Pleione . </P> <P> Hesiod, and the Homeric Hymn to Demeter, mention either a different Calypso or possibly the same Calypso as one of the Oceanid daughters of Tethys and Oceanus . Apollodorus includes the name Calypso in his list of Nereids, the daughters of Nereus and Doris . </P> <P> The etymology of Calypso's name is from καλύπτω (kalyptō), meaning "to cover", "to conceal", "to hide", or "to deceive". According to Etymologicum Magnum her name means καλύπτουσα το διανοούμενον (kalýptousa to dianooúmenon), i.e. "concealing the knowledge", which combined with the Homeric epithet δολόεσσα (dolóessa), meaning subtle or wily, justifies the hermetic character of Calypso and her island . καλύπτω is derived from Proto - Indo - European * ḱel -, making it cognate with the English word Hell . </P> <P> Calypso is remembered the most for her role in Homer's Odyssey, in which she attempts to keep the fabled Greek hero Odysseus on her island to make him her immortal husband . According to Homer, Calypso kept Odysseus prisoner at Ogygia for seven years, while Apollodorus says five years and Hyginus says one . Calypso enchants Odysseus with her singing as she moves to and fro, weaving on her loom with a golden shuttle . During this time they have sex together, although Odysseus soon comes to wish for circumstances to change . </P>
