They ignored, as much as possible, the clear exhibition of the pointed arch, and, even when they did use it, not unfrequently introduced it in such a way as to shew their contempt for it as a feature of construction; employing it often only for ornament, and never hesitating to construct it in so faulty a manner that it required to be held together with iron rods from the very first day of its erection. This fault they often found it absolutely necessary to commit, because they scarcely ever brought themselves to allow the use of the buttress; and this reluctance was a remarkable proof of their Classic sympathies. Classic architecture was as distinctly symbolic of rest as Gothic was of life; the column and lintel of the one were as still and symbolical of perfect repose, as the arch of the other, sustained by the strong arm of the flying buttress, was of life, vigour, and motion. Italian Gothic architects then, in never resorting to the buttress, avowed their feeling that a state of perfect rest was the only allowable state for a perfect building, and they preferred almost always to use the arch for its beauty only, and avowedly not for its constructional value, which they evidenced by tying it together with iron bars at its base, which there was no intention of disguising, and therefore no shamefacedness in the use of. From this, I believe, at least one beauty arose. It is obvious that the pointed arch, descending upon the capital of a shaft without any visible stay or buttress to retain it in its place, would look weak and thin; and it was soon perceived that, in order to overcome this difficulty, the only course was to add to its substance by cusping it on the under side. Thence came the trefoiled arches so frequent in Italy, and always so very lovely. As so much depended upon them, no pains were spared in bringing their outline into the very purest form. To this we owe the absolute perfection which characterizes some of the trefoiled arches in early Italian work; of this we have an example (to take one instance among many) in the tombs of the Scaligers, at Verona, in which the mass of the trefoil descending from the arch conveys to the eye the impression of a firmness which, in part, it certainly gives, but which would nevertheless be insufficient in reality for the stability of the work, without the aid of the connecting rod of iron below.
