VIII. Working with Sculptural Architecture II

The first idea you will have is that the tubular bone has to be puffed up until it is hollow inside, then you ought to arrive at the form of the head bone. But that is not the principle underlying the shapes of the bones. A tubular bone would first have to be turned round, and you would not see the similarity it has to the skullcap until you had turned it inside out like a glove. But when a person turns a glove inside out he expects it to look the same as it did before, doesn't he? This is because the glove is something dead. It is quite different with something living. If the glove were alive, the following would happen when it was turned inside out: changes would occur like the thumb and the little finger getting very long, the middle finger very short, and the palm contracting, and so on. The turning inside out and the varying elasticity of the material would bring all sorts of changes about, in fact, the glove would acquire a totally different form, although it would still be the glove. This is how you must imagine a tubular upper arm bone being turned inside out, and then a skullcap would emerge.
