§ VIII. Contracted conditions of the pinnacle porch are beautifully used in the doors of the cathedral of Florence; and the entire arrangement, in its most perfect form, as adapted to window protection and decoration, is applied by Giotto with inconceivable exquisiteness in the windows of the campanile; those of the cathedral itself being all of the same type. Various singular and delightful conditions of it are applied in Italian domestic architecture (in the Broletto of Monza very quaintly), being associated with balconies for speaking to the people, and passing into pulpits. In the north we glaze the sides of such projections, and they become bow-windows, the shape of roofing being then nearly immaterial and very fantastic, often a conical cap. All these conditions of window protection, being for real service, are endlessly delightful (and I believe the beauty of the balcony, protected by an open canopy supported by light shafts, never yet to have been properly worked out). But the Renaissance architects destroyed all of them, and introduced the magnificent and witty Roman invention of a model of a Greek pediment, with its cornices of monstrous thickness, bracketed up above the window. The horizontal cornice of the pediment is thus useless, and of course, therefore, retained; the protection to the head of the window being constructed on the principle of a hat with its crown sewn up. But the deep and dark triangular cavity thus obtained affords farther opportunity for putting ornament out of sight, of which the Renaissance architects are not slow to avail themselves. A more rational condition is the complete pediment with a couple of shafts, or pilasters, carried on a bracketed sill; and the windows of this kind, which have been well designed, are perhaps the best things which the Renaissance schools have produced: those of Whitehall are, in their way, exceedingly beautiful; and those of the Palazzo Ricardi at Florence, in their simplicity and sublimity, are scarcely unworthy of their reputed designer, Michael Angelo.
