COCY´LIUM(Κοκύλιον: Eth. Κοκυλίτης), a place in Mysia, mentioned by Xenophon with Neandria and Ilium. (Xen. Hell. 3.1. 16) In Pliny's time (5.30) it had disappeared. He mentions it between Cilia and Thebe. A place called Kutchulan, or, as others write it, Cotschiolan-Kuni, is supposed to represent Cocylium.
