§ I. We have now examined the treatment and specific kinds of ornament at our command. We have lastly to note the fittest places for their disposal. Not but that all kinds of ornament are used in all places; but there are some parts of the building, which, without ornament, are more painful than others, and some which wear ornament more gracefully than others; so that, although an able architect will always be finding out some new and unexpected modes of decoration, and fitting his ornament into wonderful places where it is least expected, there are, nevertheless, one or two general laws which may be noted respecting every one of the parts of a building, laws not (except a few) imperative like those of construction, but yet generally expedient, and good to be understood, if it were only that we might enjoy the brilliant methods in which they are sometimes broken. I shall note, however, only a few of the simplest; to trace them into their ramifications, and class in due order the known or possible methods of decoration for each part of a building, would alone require a large volume, and be, I think, a somewhat useless work; for there is often a high pleasure in the very unexpectedness of the ornament, which would be destroyed by too elaborate an arrangement of its kinds. § II. I think that the reader must, by this time, so thoroughly understand the connection of the parts of a building, that I may class together, in treating of decoration, several parts which I kept separate in speaking of construction. Thus I shall put under one head (A) the base of the wall and of the shaft; then (B) the wall veil and shaft itself; then (C) the cornice and capital; then (D) the jamb and archivolt, including the arches both over shafts and apertures, and the jambs of apertures, which are closely connected with their archivolts; finally (E) the roof, including the real roof, and the minor roofs or gables of pinnacles and arches. I think, under these divisions, all may be arranged which is necessary to be generally stated; for tracery decorations or aperture fillings are but smaller forms of application of the arch, and the cusps are merely smaller spandrils, while buttresses have, as far as I know, no specific ornament. The best are those which have least; and the little they have resolves itself into pinnacles, which are common to other portions of the building, or into small shafts, arches, and niches, of still more general applicability. We shall therefore have only five divisions to examine in succession, from foundation to roof. [Illustration: Fig. LI.]
