A courtesan or Greek Hetaira. There were two of the name; the elder was the most beautiful woman of Corinth, and lived at the time of the Peloponnesian War. The beauty of the latter excited the jealousy of the Thessalonian women, who pricked her to death with their bodkins. She was contemporary with Phryne (2 syl.), her rival, and sat to Apelles as a model.
