A Dictionary of Greek and Roman biography and mythology

(Λαφραία), a surname of Artemis among the Calydonians, from whom the worship of the goddess was introduced at Naupactus and Patrae, in Achaia. At the latter place it was not established till the time of Augustus, but it became the occasion of a great annual festival. (Paus. 4.31.6, 7.18.6. &c.; Schol. ad Eurip. Orest. 1087.) The name Laphria was traced back to a hero, Laphrius, son of Castalius, who was said to have instituted her worship at Calydon. Laphria was also a surname of Athena. (Lycoph. 356.)
