Thoosa

In Greek mythology, Thoosa (/θoʊˈoʊsə/, Greek: Θόωσα, translit. Thóōsa), also spelled Thoösa, was, according to Homer, the sea nymph daughter of the primordial sea god Phorcys, and the mother, by Poseidon, of the Cyclops Polyphemus.^[1]

^ Homer, Odyssey 1.70–73. Heubeck, Hainsworth and West, p. 69 on line 71-3, notes that "Thoosa seems to be an ad hoc invention, her name recalling the swift movement of the waves".; compare with Apollodorus, E.7.4; Nonnus, 39.293-294; Servius' Commentary on Virgil, Aeneid 5.824; Theocritus, Idylls 11.25 ff. & 62ff.
