CH. IV THE LAMP OF BEAUTY 163

(becoming, indeed, a part of Architecture), and, on the other, to a pictorial manner, when it is apt to lose its dignity, and sink into mere ingenious carving.

§ 25. Now, of Proportion so much has been written, that I believe the only facts which are of practical use have been overwhelmed and kept out of sight by vain accumulations of particular instances and estimates. Proportions are as infinite (and that in all kinds of things, as severally in colours, lines, shades, lights, and forms) as possible airs in music: and it is just as rational an attempt to teach a young architect how to proportion truly and well by calculating for him the proportions of fine works, as it would be to teach him to compose melodies by calculating the mathematical relations of the notes in Beethoven’s “Adelaïde” or Mozart’s “Requiem.” The man who has eye and intellect will invent beautiful proportions, and cannot help it; but he can no more tell us how to do it than Wordsworth could tell us how to write a sonnet, or than Scott could have told us how to plan a romance. But there are one or two general laws which can be told: they are of no use, indeed, except as preventives of gross mistakes, but they are so far worth telling and remembering; and the more so because, in the discussion of the subtle laws of Proportion (which will never be either numbered or known), architects are perpetually forgetting and transgressing the very simplest of its necessities.

§ 26. Of which the first is, that wherever Proportion exists at all, one member of the composition must be either larger than, or in some way supreme over, the rest. There is no proportion between equal things. They can have symmetry only, and symmetry without proportion is not composition. It is necessary to perfect beauty, but it is the least necessary of its elements, nor of course is there any difficulty in obtaining it. Any succession of equal things is agreeable; but to compose is to arrange unequal things, and the first thing to be done in beginning a composition is to determine which is to be the principal thing. I believe that all that has been written and taught about proportion, put together, is not
