ERYTHRÆ, in Ancient Geography, a port-town of Ætolia, on the Corinthian bay. Another Erythræ of Bœotia, near Platea and Mount Cithæron. A third Erythræ, a town of Ionia in the Hither Asia, situated in the peninsula, at its extremity, with a cognominal port. The Erythræans laid claim to the Sibyl Herophile, as their countrywoman, furnished thence Erythræa. Erythræ was famous for an ancient temple of Hercules.
