Hipparchus
3. A Pythagorean, contemporary with Lysis, the teacher of Epaminondas, about B. C. 380.
There is a letter from Lysis to Hipparchus, remonstrating with him for teaching in public, which was contrary to the injunctions of Pythagoras. (
D. L. 8.42; Iambilich.
Vit. Pythag. 17; Synes.
Epist. ad Heracl.) Clemens Alexandrinus tells us, that on the ground of his teaching in public, Hipparchus was expelled from the society of the Pythagoreans, who erected a monument to him, as if he had been dead. (
Strom. v. p. 574; comp. Lycurg.
ad v. Leocr. 30.) Stobaeus (
Serm. cvi.) has preserved a fragment from his book
Περὶ εὐθυμίας. (Fabric.
Bibl. Graec. vol. i. pp. 847, 886.)
