mirror seem now to withdraw the image into its depths, now to extrude it forth to view? Why do concave mirrors when held at right angles to the rays of the sun kindle tinder set opposite them? What is the cause of the prismatic colours of the rainbow, or of the appearance in heaven of two rival images of the sun, with sundry other phenomena treated in a monumental volume by Archimedes of Syracuse, a man who showed extraordinary and unique subtlety in all branches of geometry, but was perhaps particularly remarkable for his frequent and attentive inspection of mirrors. If you had only read this book, Aemilianus, and, instead of devoting yourself to the study of your fields and their dull clods, had studied the mathematician's slate and blackboard, believe me, although your face is hideous enough for a tragic mask of Thyestes, you would assuredly, in your desire for the acquisition of knowledge, look into the glass and sometimes leave your plough to marvel at the numberless furrows with which wrinkles have scored your face.

But I should not be surprised if you prefer me to speak of your ugly deformity of a face and to be silent about your morals, which are infinitely more repulsive than your features. I will say nothing of them. In the first place I am not naturally of a quarrelsome disposition, and secondly I am glad to say that until quite recently you might have been white or black for all I knew. Even now my knowledge of you is inadequate. The reason for this is that your rustic occupations have kept you in obscurity, while I have been occupied by my studies, and so the shadow cast about you by your insignificance has shielded your character from scrutiny, while I for my part take no interest in others' ill deeds, but have always thought it more important to conceal my own faults than to track out those of others. As a result you have the advantage of one who, while he is himself shrouded in darkness, surveys another who chances to have taken his stand in the full light of day. You from your darkness can with ease form an opinion as to what I am doing in my not undistinguished position before all the world; but your position is so abject, so obscure, and so withdrawn from the light of publicity that you are by no means so conspicuous.

17. I neither know nor care to know whether you have slaves to till your fields or whether you do so by interchange of service with your neighbours. But you know that at Oea I gave three slaves their freedom on the same day, and your advocate has cast it in my teeth together with other actions of mine of which you have given him information. And yet but a few minutes earlier he had declared that I came to Oea accompanied by no more than one slave. I challenge you to tell me how I could have made one slave into three free men. But perhaps this is one of my feats of magic. Has lying made you blind, or shall I rather say that from force of habit you are incapable of speaking the truth? 'Apuleius,' you say, 'came to Oea with one slave,' and then only a very few words later you blurt out, 'Apuleius on one and the same day at Oea gave three slaves their freedom.' Not even the assertion that I had come with three slaves and had given them all their freedom would have been credible: but suppose I had done so, what reason have you for regarding three slaves as a mark of my poverty, rather than for considering three freed men as a proof of my wealth? Poor Aemilianus, you have not the least idea how to accuse a philosopher: you reproach me for the scantiness of my household, whereas it would really have been my duty to have laid claim, however falsely, to such poverty. It would have redounded to my credit, for I know that not only philosophers of whom I boast myself a follower, but also generals of the Roman people have gloried in the small number of their slaves. Have your advocates really never read that Marcus Antonius, a man who had filled the office of consul, had but eight slaves in his house? That that very Carbo who obtained supreme control of Rome had fewer by one? That Manius Curius, famous beyond all men for the crowns of victory that he had won, Manius Curius who thrice led the triumphal procession through the same gate of Rome, had but two servants to attend him in camp, so that in good truth that same man who triumphed over the Sabines, the Samnites, and Pyrrhus had fewer slaves than triumphs? Marcus Cato did not wait for others to tell it of him, but himself records the fact in one of his speeches that when he set out as consul for Spain he took but three slaves from the city with him. When, however, he came to stay at a state residence, the number seemed insufficient, and he ordered two slaves to be bought in the market to wait on him at table, so that he took five in all to Spain. Had Pudens come across these facts in his reading, he would, I think, either have omitted this particular slander or would have preferred to reproach me on the ground that three slaves were too large rather than too small an establishment for a philosopher.
