Rufus. From Epictetus on friendship
1What man among us does not admire the saying of Lycurgus the Lacedaemonian? For when he had been blinded in one eye by one of his fellow-citizens, and the people had turned over the young man to him, to take whatever vengeance upon the culprit he might desire, this he refrained from doing, but brought him up and made a good man of him, and presented him in the theatre. And when the Lacedaemonians expressed their surprise, he said, "This man when I received him at your hands was insolent and violent; I am returning him to you a reasonable and public-spirited person."
