OETA (mod. Kotavothra)  , a mountain to the south of Thessaly, in Greece, forming a boundary between the valleys of the Spercheius and the Boeotian Cephissus . It is an offshoot of the Pindus range, 7o8o ft. high . In its eastern portion, called Callidromus, it comes close to the sea, leaving only a narrow passage known as the famous pass of Thermopylae (q.v.) . There was also a high pass to the west of Callidromus leading over into the upper Cephissus valley . In mythology Oeta is chiefly celebrated as the scene of the funeral pyre on which Heracles burnt himself before his admission to Olympus .
