ERYTHRAE, one of the Ionian cities of Asia Minor, situ ated on a small peninsula stretching into the Bay of Erythrae, at an equal distance from the mountains Mimas and Corycus, and directly opposite the island of Chios. In the peninsula excellent wine was produced. The town was said to have been founded by Ionians under Knopos, son of Codrus. Never a large city, it sent only eight ships to the battle of Lade. The Erythraeans owned for a considerable time the supremacy of Athens, but towards the close of the Peloponnesian war they threw off their allegiance to that city. After the battle of Cnidus, however, they received Conon, and paid him honours in an inscription, still extant. The ruins include well preserved Hellenis tic walls with towers, of which five are still visible. The acropolis (28o ft.) has the theatre on its north slope, and eastwards lie many remains of Byzantine buildings.
