CHAPTER XIV.

THE ROOF CORNICE.

§ I. It will be remembered that in the Sixth Chapter we paused (§ X.) at the point where the addition of brackets to the ordinary wall cornice would have converted it into a structure proper for sustaining a roof. Now the wall cornice was treated throughout our enquiry (compare Chapter VII. § V.) as the capital of the wall, and as forming, by its concentration, the capital of the shaft. But we must not reason back from the capital to the cornice, and suppose that an extension of the principles of the capital to the whole length of the wall, will serve for the roof cornice; for all our conclusions respecting the capital were based on the supposition of its being adapted to carry considerable weight condensed on its abacus: but the roof cornice is, in most cases, required rather to project boldly than to carry weight; and arrangements are therefore to be adopted for it which will secure the projection of large surfaces without being calculated to resist extraordinary pressure. This object is obtained by the use of brackets at intervals, which are the peculiar distinction of the roof cornice.

§ II. Roof cornices are generally to be divided into two great families: the first and simplest, those which are composed merely by the projection of the edge of the roof mask over the wall, sustained by such brackets or spurs as may be necessary; the second, those which provide a walk round the edge of the roof, and which require, therefore, some stronger support, as well as a considerable mass of building above or beside the roof mask, and a parapet. These two families we shall consider in succession.

§ III. 1. The Eaved Cornice. We may give it this name, as represented in the simplest form by cottage eaves. It is used, however, in bold projection, both in north, and south, and east; its use being, in the north, to throw the rain well away from the wall of the building; in the south to give it shade; and it is ordinarily constructed of the ends of the timbers of the roof mask (with their tiles or shingles continued to the edge of the cornice), and sustained by spurs of timber. This is its most picturesque and natural form; not inconsistent with great splendor of architecture in the mediæval Italian domestic buildings, superb in its mass of cast shadow, and giving rich effect to the streets of Swiss towns, even when they have no other claim to interest. A farther value is given to it by its waterspouts, for in order to avoid loading it with weight of water in the gutter at the edge, where it would be a strain on the fastenings of the pipe, it has spouts of discharge at intervals of three or four feet,—rows of magnificent leaden or iron dragons’ heads, full of delightful character, except to any person passing along the middle of the street in a heavy shower. I have had my share of their kindness in my time, but owe them no grudge; on the contrary, much gratitude for the delight of their fantastic outline on the calm blue sky, when they had no work to do but to open their iron mouths and pant in the sunshine.

§ IV. When, however, light is more valuable than shadow, or when the architecture of the wall is too fair to be concealed, it becomes necessary to draw the cornice into narrower limits; a change of considerable importance, in that it permits the gutter, instead of being of lead and hung to the edge of the cornice, to be of stone, and supported by brackets in the wall, these brackets becoming proper recipients of after decoration (and sometimes associated with the stone channels of discharge, called gargoyles, which belong, however, more properly to the other family of cornices). The most perfect and beautiful example of this kind of cornice is the Venetian, in which the rain from the tiles is received in a stone gutter supported by small brackets, delicately moulded, and having its outer lower edge decorated with the English dogtooth moulding, whose sharp zigzag mingles richly with the curved edges of the tiling. I know no cornice more beautiful in its extreme simplicity and serviceableness.

§ V. The cornice of the Greek Doric is a condition of the same kind, in which, however, there are no brackets, but useless appendages hung to the bottom of the gutter (giving, however, some impression of support as seen from a distance), and decorated with stone symbolisms of raindrops. The brackets are not allowed, because they would interfere with the sculpture, which in this architecture is put beneath the cornice; and the overhanging form of the gutter is nothing more than a vast dripstone moulding, to keep the rain from such sculpture: its decoration of guttæ, seen in silver points against the shadow, is pretty in feeling, with a kind of continual refreshment and remembrance of rain in it; but the whole arrangement is awkward and meagre, and is only endurable when the eye is quickly drawn away from it to sculpture.

§ VI. In later cornices, invented for the Greek orders, and farther developed by the Romans, the bracket appears in true importance, though of barbarous and effeminate outline: and gorgeous decorations are applied to it, and to the various horizontal mouldings which it carries, some of them of great beauty, and of the highest value to the mediæval architects who imitated them. But a singularly gross mistake was made in the distribution of decoration on these rich cornices (I do not know when first, nor does it matter to me or to the reader), namely, the charging with ornament the under surface of the cornice between the brackets, that is to say, the exact piece of the whole edifice, from top to bottom, where ornament is least visible. I need hardly say much respecting the wisdom of this procedure, excusable only if the whole building were covered with ornament; but it is curious to see the way in which modern architects have copied it, even when they had little enough ornament to spare. For instance, I suppose few persons look at the Athenæum Club-house without feeling vexed at the meagreness and meanness of the windows of the ground floor: if, however, they look up under the cornice, and have good eyes, they will perceive that the architect has reserved his decorations to put between the brackets; and by going up to the first floor, and out on the gallery, they may succeed in obtaining some glimpses of the designs of the said decorations.
