On Clothes
As, then, in the fashioning of our clothes, we must keep clear of all strangeness, so in the use of them we must beware of extravagance. For neither is it seemly for the clothes to be above the knee, as they say was the case with the Lacedæmonian virgins; nor is it becoming for any part of a woman to be exposed. Though you may with great propriety use the language addressed to him who said, “Your arm is beautiful; yes, but it is not for the public gaze. Your thighs are beautiful; but, was the reply, for my husband alone. And your face is comely. Yes; but only for him who has married me.” But I do not wish chaste women to afford cause for such praises to those who, by praises, hunt after grounds of censure; and not only because it is prohibited to expose the ankle, but because it has also been enjoined that the head should be veiled and the face covered; for it is a wicked thing for beauty to be a snare to men. Nor is it seemly for a woman to wish to make herself conspicuous, by using a purple veil. Would it were possible to abolish purple in dress, so as not to turn the eyes of spectators on the face of those that wear it! But the women, in the manufacture of all the rest of their dress, have made everything of purple, thus inflaming the lusts. And, in truth, those women who are crazy about these stupid and luxurious purples, “purple (dark) death has seized,” according to the poetic saying. On account of this purple, then, Tyre and Sidon, and the vicinity of the Lacedæmonian Sea, are very much desired; and their dyers and purple-fishers, and the purple fishes themselves, because their blood produces purple, are held in high esteem. But crafty women and effeminate men, who blend these deceptive dyes with dainty fabrics, carry their insane desires beyond all bounds, and export their fine linens no longer from Egypt, but some other kinds from the land of the Hebrews and the Cilicians. I say nothing of the linens made of Amorgos and Byssus. Luxury has outstripped nomenclature.
The covering ought, in my judgment, to show that which is covered to be better than itself, as the image is superior to the temple, the soul to the body, and the body to the clothes. But now, quite the contrary, the body of these ladies, if sold, would never fetch a thousand Attic drachms. Buying, as they do, a single dress at the price of ten thousand talents, they prove themselves to be of less use and less value than cloth. Why in the world do you seek after what is rare and costly, in preference to what is at hand and cheap? It is because you know not what is really beautiful, what is really good, and seek with eagerness shows instead of realities from fools who, like people out of their wits, imagine black to be white.
