MEGARIS, in Ancient Geography, the country of the Megarians, is described as a rugged region, like Attica; the mountain called Onean or Asinine, now Macriplayi or the long mountain, extending through it towards Bœotia and Mount Cithæron. It belonged to Ionia or Attica, until it was taken by the Peloponnesians in the reign of Codrus, when a colony of Dorians settled in it. This territory had Attica to the east, Bœotia to the north and west, and the isthmus of Corinth to the south.
