Iamblichus calls him a Pythagorean. According to Themistius, Plato reckoned him among the sophists. Specifically, in Plato's dialogue Protagoras, the sophist Protagoras lists Iccus alongside Homer, Hesiod, Simonides, Orpheus, Musaeus, Herodicus, Agathocles tutor of Damon, and as fellow sophists (that is, improvers of youth) who chose to present themselves as poets, athletes, or musicians for fear of public disapproval.
