Corinthus
Called in Homer Ephyra, a city on the above-mentioned Isthmus. It had two harbors-Cenchreae on the east or Saronic Gulf, and Lechaeum on the west or Cryssaean Gulf. Its favorable position, between two seas, raised Corinth in very early times to great commercial prosperity, and made it the emporium of the trade between Europe and Asia. At Corinth the first triremes were built; and the first sea-fight on record was between the Corinthians and their colonists, the Corcyraeans.
