Section XV

Gradual variation.

But as perfectly¹ beautiful bodies are not composed of angular parts, so their parts never continue long in the same right line.16 They vary their direction every moment, and they change under the eye by a deviation² continually carrying on, but for whose beginning or end you will find it difficult to ascertain³ a point. The view of a beautiful bird will illustrate⁴ this observation. Here we see the head increasing insensibly to the middle, from whence it lessens⁵ gradually until it mixes with the neck; the neck loses itself in a larger swell⁶, which continues to the middle of the body, when the whole decreases again to the tail; the tail takes a new direction, but it soon varies its new course, it blends again with the other parts, and the line is perpetually changing, above, below, upon every side. In this description I have before me the idea of a dove; it agrees very well with most of the conditions of beauty. It is smooth and downy; its parts are (to use that expression) melted into one another; you are presented with no sudden protuberance through the whole, and yet the whole is continually changing. Observe that part of a beautiful woman where she is perhaps the most beautiful, about the neck and breasts; the smoothness, the softness, the easy and insensible swell; the variety of the surface, which is never for the smallest space the same; the deceitful maze⁷ through which the unsteady eye slides giddily, without knowing where to fix, or whither it is carried. Is not this a demonstration⁸ of that change of surface, continual, and yet hardly perceptible at any point, which forms one of the great constituents⁹ of beauty? It gives me no small pleasure to find that I can strengthen my theory in this point by the opinion of the very ingenious Mr. Hogarth, whose idea of the line of beauty I take in general to be extremely just. But the idea of variation, without attending so accurately¹⁰ to the manner of the variation, has led him to consider angular figures as beautiful; these figures, it is true, vary greatly, yet they vary in a sudden and broken manner, and I do not find any natural object which is angular, and at the same time beautiful. Indeed, few natural objects are entirely¹¹ angular. But I think those which approach the most nearly to it are the ugliest. I must add, too, that so for as I could observe of nature, though the varied¹² line is that alone in which complete beauty is found, yet there is no particular line which is always found in the most completely beautiful, and which is therefore beautiful in preference to all other lines. At least I never could observe it.
