Sayings of Socrates 59

Socrates was sharply criticized, according to Aristotle in his third book On Poetry, by a certain Antilochus of Lemnos, and by Antiphon the soothsayer, just as Pythagoras was by Cylon of Croton, or as Homer was assailed in his lifetime by Syagrus, and after his death by Xenophanes of Colophon. 

So too Hesiod was criticized in his lifetime by Cercops, and after his death by the aforesaid Xenophanes; Pindar by Amphimenes of Cos; Thales by Pherecydes; Bias by Salarus of Priene; Pittacus by Antimenidas and Alcaeus; Anaxagoras by Sosibius; and Simonides by Timocreon.
