In fact, they did not need any, either to help them keep their bodies pure or to keep them warm. In hot countries, even now, few clothes are worn by the very young people, and many children never wear any at all, yet no one thinks any more of it than we do of seeing our baby naked. There are also countries where women always keep their faces covered, yet do not care one bit if the rest of their body is seen. Clothes, you see, are mostly a matter of habit and custom. It is the custom here to wear a certain kind of garments, so, of course, people follow that custom.
Artists study so long, that they little by little find out all the beauty of the human body.
Every curve, every dimple, every shadow means something to them. Artists like to paint the human form, not only because they see all its beauty, and because they can best show their skill in doing so, but also because people's clothes change so much that pictures soon look old-fashioned and ridiculous. So that a picture should really be beautiful it must be like our idea of what it is meant to represent. If the angel wore a tailor-made gown and had gloves on, the picture would lose nearly all of its beauty. The artist might know how to paint gowns and gloves so well that they looked real, but yet, as they would be out of place there, they would spoil the picture.
