while in medicine he was the pupil of Philistion the Sicilian. Eudoxus also left some excellent commentaries. He had a son Aristagoras, who had a son Chrysippus, the pupil of Aethlius. To this Chrysippus we owe a medical work on the treatment of the eye, speculations upon nature having occupied his mind.
