ICUS(Ἴκος: Eth. Ἴκιος), one of the group of islands off the coast of Magnesia in Thessaly, lay near Peparethus, and was colonised at the same time by the Cnossians of Crete. (Scymn. Chins, 582; Strab. 9. p. 436; Appian, App. BC 5.7.) The fleet of Attalus and the Rhodians sailed past Scyrus to Icus. (Liv. 31.45.) Phanodemus wrote an account of this insignificant island. (Steph. B. s. v.) It is now called Sarakńo. (Leake, Northern Greece, vol. 3. p. 312.)
