(Κύθνος; Kýthnos, Lat. Cythnus, the modern Thermia). Island in the western Cyclades (86 km2): 21 km long, 11 km wide; a monotonous, undulating plain (height 200 to 350 m.), predominantly slate. Its rugged coastline offers no good harbours. Two hot springs, already active in Roman times, are situated near Lutra on the north coast. C. is little fertile, short of water and virtually without trees. In antiquity C. was known for its fine cheese (Poll. 6,63; Eust. in Dionys. Per. 525; Plin. HN 13,134; Steph. Byz. s.v. Kythnos).
