The master that taught him music, most authors are agreed, was Damon (whose name, they say, ought to be pronounced with the first syllable short). Though Aristotle tells us that he was thoroughly practiced in all accomplishments of this kind by Pythoclides. Damon, it is not unlikely, being a sophist, out of policy, sheltered himself under the profession of music to conceal from people in general his skill in other things, and under this pretense attended Pericles, the young athlete of politics, so to say, as his training-master in these exercises. Damon's lyre, however, did not prove altogether a successful blind; he was banished the country by ostracism for ten years, as a dangerous intermeddler and a favorer of arbitrary power, and, by this means, gave the stage occasion to play upon him. As, for instance, Plato, the comic poet, introduces a character, who questions him -- Tell me, if you please, Since you're the Chiron who taught Pericles. Pericles, also, was a hearer of Zeno, the Eleatic, who treated of natural philosophy in the same manner as Parmenides did, but had also perfected himself in an art of his own for refuting and silencing opponents in argument; as Timon of Phlius describes it, -- Also the two-edged tongue of mighty Zeno, who, Say what one would, could argue it untrue. But he that saw most of Pericles, and furnished him most especially with a weight and grandeur of sense, superior to all arts of popularity, and in general gave him his elevation and sublimity of purpose and of character, was Anaxagoras of Clazomenae; whom the men of those times called by the name of Nous, that is, mind, or intelligence, whether in admiration of the great and extraordinary gift he displayed for the science of nature, or because that he was the first of the philosophers who did not refer the first ordering of the world to fortune or chance, nor to necessity or compulsion, but to a pure, unadulterated intelligence, which in all other existing mixed and compound things acts as a principle of discrimination, and of combination of like with like.
