Cios
(
*Ki=os), a son of Olympus, from whom Cios (Prusa) on the Propontis derived its name, as he was believed to have led thither a band of colonists from Miletus. (Schol.
ad Theocrit. 13.30;
ad Apollon. Rhod. 1.1177.) Strabo (
xii. p.564) calls him a companion of Heracles who founded Cios on his return from Colchis.
