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. (Od.
5.28, &c., 7.254, &c.) - A Dictionary of Greek and Roman

Calypso in Wikipedia
Calypso (Greek: Καλυψώ Kalypsō) was a nymph in Greek
mythology, who lived on the island of Ogygia, where she kept
Odysseus prisoner for a number of years. She is generally said
to be the daughter of the Titan Atlas.
Perhaps the same or different Calypsos, are mentioned by
Hesiod as one of the Oceanid daughters of Tethys and
Oceanus, and Pseudo-Apollodorus as one of the Nereid
daughters of Nereus and Doris....
