(Ὠλίαρος; Ōlíaros). Largest (38 km2) of the islands grouped around Paros, modern Antiparos (Str. 10,5,3; Mela 2,111). The Saliangos reef was the site of the earliest known late Neolithic settlement in the Cyclades. Early Cycladic graves have come to light on the neighbouring island of Diplo. The stalactite caves on O. were much frequented in ancient times already. In other respects the history of O. is closely connected with Paros.
