§ 1. I have hardly kept my promise. The reader has decorated but little for himself as yet; but I have not, at least, attempted to bias his judgment. Of the simple forms of decoration which have been set before him, he has been always left free to choose; and the stated restrictions in the methods of applying them have been only those which followed on the necessities of construction previously determined. These having been now defined, I do indeed leave my reader free to build; and with what a freedom! All the lovely forms of the universe set before him, whence to choose, and all the lovely lines that bound their substance or guide their motion; and of all these lines,—and there are myriads of myriads in every bank of grass and every tuft of forest; and groups of them, divinely harmonised, in the bell of every flower, and in every several member of bird and beast,—of all these lines, for the principal forms of the most important members of architecture, I have used but Three! What, therefore, must be the infinity of the treasure in them all? There is material enough in a single flower for the ornament of a score of cathedrals: but suppose we were satisfied with less exhaustive appliance, and built a score of cathedrals, each to illustrate a single flower? that would be better than trying to invent new styles, I think.
