OCA´LEA or OCALEIA(Ὠκαλέα, Ὠκάλεια: Eth. Ὠκαλεύς), an ancient city of Boeotia, mentioned by Homer, situated upon a small stream of the same name, at an equal distance from Haliartus and Alalcomenae. It lay in the middle of a long narrow plain, bounded on the east by the heights of Haliartus, on the west by the mountain Tilphossium, on the south by a range of low hills, and on the north by the lake Copais. This town was dependent upon Haliartus. The name is probably only a dialectic form of Oechalia. Its site is indicated by several squared blocks on the right bank of the stream. (Hom. Il. 2.501, Eymn.
