as to surpass all the other scholars, and rose to be himself head of the school in the 116th Olympiad.¢ Antigonus of Carystus in his Biographies says that his father was foremost among the citizens and kept horses to compete in the chariot-race ; that Polemo himself had been defendant in an action brought by his wife, who charged him with cruelty owing to the irregularities of his life; but that, from the time when he began to study philosophy, he acquired such strength of character as always to maintain the same unrufHed calm of demeanour. Nay more, he never lost control of his voice. This in fact accounts for the fascination which he exercised over Crantor.? Certain it is that, when a mad dog bit him in the back of his thigh, he did not even turn pale, but remained undisturbed by all the clamour which arose in the city at the news of what had happened. In the theatre too he was singularly unmoved. For instance, Nicostratus, who was nicknamed Clytemnestra, was once reading to him and Crates something from Homer; and, while Crates was deeply affected, he was no more moved than if he had not heard him. Altogether he was a man such as Melanthius the painter describes in his work On Painting. ‘There he says that a certain wilfulness and stubbornness should be stamped on works of art, and that the same holds good of character. Polemo used to say that we should exercise ourselves with facts and not with mere logical speculations, which leave us, like a man who has got by heart some paltry handbook on harmony but never practised, able, indeed, to win admiration for skill in asking questions, but utterly at variance with ourselves in the ordering of our lives.
