11 And to show that I do not speak this in a way of flattery, but that it will certainly be so, I will relate to you an ancient piece of history, that you may understand that no armies, nor warlike weapons, nor money, nor multitude of subjects, nor any other such things are wont to make sovereigns so illustrious, as wisdom of soul and gentleness. It is related of the blessed Constantine, that on one occasion, when a statue of himself had been pelted with stones, and many were instigating him to proceed against the perpetrators of the outrage; saying, that they had disfigured his whole face by battering it with stones, he stroked his face with his hand, and smiling gently, said, “I am quite unable to perceive any wound inflicted upon my face. The head appears sound, and the face also quite sound.” Thus these persons, overwhelmed with shame, desisted from their unrighteous counsel.
This saying, even to the present day, all repeat; and length of time has neither weakened nor extinguished the memory of such exalted wisdom. How much more illustrious is such an action, than any number of warlike trophies! Many and great titles did he build, and many barbarous tribes did he conquer; not one of which we now remember; but this saying is repeated over and over again, to the present day; and those who follow us, as well as those who come after them, will all hear of it. Nor indeed is this the only admirable thing; that they will hear of it; but that when men speak of it, they do so with approbation and applause; and those who hear of it, receive it with the like; and there is no one who, when he has heard it, is able to remain silent, but each at once cries out, and applauds the man who uttered it, and prays that innumerable blessings may be his lot even now deceased. But if among men, this saying has gained him so much honour, how many crowns will he obtain with the merciful God!
