Chap. xxvi.—60. Petilianus said: "For if you mix what is false with what is true, falsehood often imitates the truth by treading in its steps. Just in the same way a picture imitates the true man of nature, depicting with its colours the false resemblance of truth. And in the same way, too, the brilliancy of a mirror catches the countenance, so as to represent the eyes of him who gazes on it. In this way it presents to each comer his own countenance, so that the very features of the comer meet themselves in turn; and of such virtue is the falsehood of a clear mirror, that the very eyes which see themselves recognise themselves as though in some one else. And even when a shadow stands before it, it doubles the reflection, dividing its unity in great part through a falsehood. Must we then hold that anything is true, because a lying representation is given of it? But it is one thing to paint a man, another to give birth to one. For does any one represent fictitious children to a man who wishes for an heir? or would any one look for true heirs in the falsehood of a picture? Truly it is a proof of madness to fall in love with a picture, letting go one's hold of what is true."
