Orations

⁷ What branch of learning did he not master, or rather, in what branch of study did he not surpass those who had made it their sole study? Whom did he allow even to approach him, not only of his own time and age, but even of his elders, who had devoted many more years to study? All subjects he studied as one, and each as thoroughly as if he knew no other. The brilliant in intellect, he surpassed in industry, the devoted students in quickness of perception; nay, rather he outstripped in rapidity those who were rapid, in application those who were laborious, and in both respects those who were distinguished in both.

From geometry and astronomy, that science so dangerous to anyone else, he gathered all that was helpful (I mean that he was led by the harmony and order of the heavenly bodies to reverence their Maker), and avoided what is injurious; not attributing all things that are or happen to the influence of the stars, like those who raise their own fellow-servant, the creation, in rebellion against the Creator, but referring, as is reasonable, the motion of these bodies, and all other things besides, to God.

In arithmetic and mathematics, and in the wonderful art of medicine, in so far as it treats of physiology and temperament, and the causes of disease, in order to remove the roots and so destroy their offspring with them, who is there so ignorant or contentious as to think him inferior to himself, and not to be glad to be reckoned next to him, and carry off the second prize? This indeed is no unsupported assertion, but East and West alike, and every place which he afterward visited, are as pillars inscribed with the record of his learning.
