Erythræ was the native place of the Sibyl, an ancient inspired prophetess. In the time of Alexander there was another Sibyl, who was also a prophetess, whose name was Athenais, a native of the same city; and in our age there was Heracleides the Herophilian physician, a native of Erythræ, a fellow-student of Apollonius surnamed Mus.
