The boy and dolphin as a coin-type of the Iasians is mentioned by Aelian (Hist. Anim., vi. 15), Plutarch (De solert. Anim., 36) and Pollux (ix. 84). The story of the love of a dolphin for a youth of Iasus, who is called Hermias by Plutarch and Pliny (N. H., ix. 8), and Dionysius by Athenaeus (xiii. 606), may have had an historical basis, for Alexander the Great is said to have ordered the boy to be sent to his court.
