2. And in the first place, he was of a chastity so inviolate that, after the loss of his wife he never indulged in any sexual pleasures, recollecting what is told in Plato of Sophocles the tragedian, that being asked when he was a very old man whether he still had any commerce with women, he said "No," with this further addition, that "he was glad to say that he had at all times avoided such indulgence as a tyrannous and cruel master." 3. And to strengthen this resolution he often called to mind the words of the lyric poet Bacchylides, whom he used to read with pleasure, and who said that as a fine painter makes a handsome face, so chastity adorns a life that aims at greatness. And even when in the prime of life he so carefully avoided this taint that there was never the least suspicion of his becoming enamoured even of any of his household, as has often happened. 4. And this kind of temperance increased in him, being strengthened by a sparing indulgence in eating and sleeping, to which he rigidly adhered whether abroad or at home. For in time of peace his frugal allowance of food was a marvel to all who knew him, as resembling that of a man always wishing to resume the philosopher's cloak. And in his various campaigns he used commonly only to take a little plain food while standing, as is the custom of soldiers. 5. And when after being fatigued by labour he had refreshed his body with a short rest, as soon as he awoke he would go by himself round all the sentries and outposts; after which he retired to his serious studies. 6. And if any voice could bear witness to his use of the nocturnal lamp, by which he pursued his lucubrations, it would show that there was a vast difference between some emperors and him, who did not even indulge himself in those pleasures permitted by the necessities of human nature. 7. Of his prudence there were also many proofs, of which it will be sufficient to recount a few. He was profoundly skilled in war, and also in the arts of peace. He was very attentive to courtesy, claiming just so much respect as he considered sufficient to mark the difference between contempt and insolence. He was older in virtue than in years, being eager to acquire all kinds of knowledge. He was a most incorruptible judge, a rigid censor of morals and manners, mild, a despiser of riches, and indeed of all mortal things. Lastly, it was a common saying of his, "That it was beneath a wise man, since he had a soul, to aim at acquiring praise by his body." 8. Of his justice there are many conspicuous proofs: first, because, with all proper regard to circumstances and persons, he inspired awe without being cruel; secondly, because he repressed vice by making examples of a few, and also because he threatened severe punishment more frequently than he employed it.
