Kithairon (Κιθαιρών, -ῶνος) is a mountain range ("No corner of Kithairon echoless", Oedipus Rex 440) about 10 miles (16 km) long, in central Greece, standing between Boeotia in the north and Attica in the south. It is mainly composed of limestone and rises to 4,623 ft (1,409 m). Its northeast side is formed by the mountain Pastra. The people of Plataea also personified the mountain as their primal king: "The Plataians know of no king except Asopos and Kithairon before him, holding that the latter gave his name to the mountain, the former to the river". (Pausanias 9.1.1)
