Sometime during the early part of this golden age there came to Athens a middle-aged man from Clazomenae, who, from our present stand-point, was a more interesting personality than perhaps any other in the great galaxy of remarkable men assembled there. The name of this new-comer was Anaxagoras. It was said in after-time, we know not with what degree of truth, that he had been a pupil of Anaximenes. If so, he was a pupil who departed far from the teachings of his master.
