Mysia is the northwestern region of Anatolia (Asia Minor) located on the shore of the Propontis (Marmara Sea) between Troas and Bithynia. The chief physical features of Mysia are the two mountains, Mount Olympus at (7600 ft) in the north and Mount Temnus in the south. The most important cities were Pergamon in the valley of the Caïcus, and Cyzicus on the Propontis. The whole sea-coast was studded with Greek towns, several of which were places of considerable importance; thus the northern portion included Parium, Lampsacus and Abydos, and the southern Assos, Adramyttium. Further south, on the Eleatic Gulf, were Elaea, Myrina and Cyme.
