The Stones of Venice, Volume 1 (of 3)

by John Ruskin

§ VII. Such as they are, or were, these cornices were soon considered essential parts of the “order” to which they belonged; and the same wisdom which endeavored to fix the proportions of the orders, appointed also that no order should go without its cornice. The reader has probably heard of the architectural division of superstructure into architrave, frieze, and cornice; parts which have been appointed by great architects to all their work, in the same spirit in which great rhetoricians have ordained that every speech shall have an exordium, and narration, and peroration. The reader will do well to consider that it may be sometimes just as possible to carry a roof, and get rid of rain, without such an arrangement, as it is to tell a plain fact without an exordium or peroration; but he must very absolutely consider that the architectural peroration or cornice is strictly and sternly limited to the end of the wall’s speech,—that is, to the edge of the roof; and that it has nothing whatever to do with shafts nor the orders of them. And he will then be able fully to enjoy the farther ordinance of the late Roman and Renaissance architects, who, attaching it to the shaft as if it were part of its shadow, and having to employ their shafts often in places where they came not near the roof, forthwith cut the roof-cornice to pieces and attached a bit of it to every column; thenceforward to be carried by the unhappy shaft wherever it went, in addition to any other work on which it might happen to be employed. I do not recollect among any living beings, except Renaissance architects, any instance of a parallel or comparable stupidity: but one can imagine a savage getting hold of a piece of one of our iron wire ropes, with its rings upon it at intervals to bind it together, and pulling the wires asunder to apply them to separate purposes; but imagining there was magic in the ring that bound them, and so cutting that to pieces also, and fastening a little bit of it to every wire.

§ VIII. Thus much may serve us to know respecting the first family of wall cornices. The second is immeasurably more important, and includes the cornices of all the best buildings in the world. It has derived its best form from mediæval military architecture, which imperatively required two things; first, a parapet which should permit sight and offence, and afford defence at the same time; and secondly, a projection bold enough to enable the defenders to rake the bottom of the wall with falling bodies; projection which, if the wall happened to slope inwards, required not to be small. The thoroughly magnificent forms of cornice thus developed by necessity in military buildings, were adopted, with more or less of boldness or distinctness, in domestic architecture, according to the temper of the times and the circumstances of the individual—decisively in the baron’s house, imperfectly in the burgher’s: gradually they found their way into ecclesiastical architecture, under wise modifications in the early cathedrals, with infinite absurdity in the imitations of them; diminishing in size as their original purpose sank into a decorative one, until we find battlements, two-and-a-quarter inches square, decorating the gates of the Philanthropic Society.

§ IX. There are, therefore, two distinct features in all cornices of this kind; first, the bracket, now become of enormous importance and of most serious practical service; the second, the parapet: and these two features we shall consider in succession, and in so doing, shall learn all that is needful for us to know, not only respecting cornices, but respecting brackets in general, and balconies.

§ X. 1. The Bracket. In the simplest form of military cornice, the brackets are composed of two or more long stones, supporting each other in gradually increasing projection, with roughly rounded ends, [Fig. XXXVIII.], and the parapet is simply a low wall carried on the ends of these, leaving, of course, behind, or within it, a hole between each bracket for the convenient dejection of hot sand and lead. This form is best seen, I think, in the old Scotch castles; it is very grand, but has a giddy look, and one is afraid of the whole thing toppling off the wall. The next step was to deepen the brackets, so as to get them propped against a great depth of the main rampart, and to have the inner ends of the stones held by a greater weight of that main wall above; while small arches were thrown from bracket to bracket to carry the parapet wall more securely. This is the most perfect form of cornice, completely satisfying the eye of its security, giving full protection to the wall, and applicable to all architecture, the interstices between the brackets being filled up, when one does not want to throw boiling lead on any body below, and the projection being always delightful, as giving greater command and view of the building, from its angles, to those walking on the rampart. And as, in military buildings, there were usually towers at the angles (round which the battlements swept) in order to flank the walls, so often in the translation into civil or ecclesiastical architecture, a small turret remained at the angle, or a more bold projection of balcony, to give larger prospect to those upon the rampart. This cornice, perfect in all its parts, as arranged for ecclesiastical architecture, and exquisitely decorated, is the one employed in the duomo of Florence and campanile of Giotto, of which I have already spoken as, I suppose, the most perfect architecture in the world.

§ XI. In less important positions and on smaller edifices, this cornice diminishes in size, while it retains its arrangement, and at last we find nothing but the spirit and form of it left; the real practical purpose having ceased, and arch, brackets and all, being cut out of a single stone. Thus we find it used in early buildings throughout the whole of the north and south of Europe, in forms sufficiently represented by the two examples in [Plate IV.]: 1, from St. Antonio, Padua; 2, from Sens in France.

§ XII. I wish, however, at present to fix the reader’s attention on the form of the bracket itself; a most important feature in modern as well as ancient architecture. The first idea of a bracket is that of a long stone or piece of timber projecting from the wall, as a, [Fig. XXXIX.], of which the strength depends on the toughness of the stone or wood, and the stability on the weight of wall above it (unless it be the end of a main beam). But let it be supposed that the structure at a, being of the required projection, is found too weak: then we may strengthen it in one of three ways; (1) by putting a second or third stone beneath it, as at b; (2) by giving it a spur, as at c; (3) by giving it a shaft and another bracket below, d; the great use of this arrangement being that the lowermost bracket has the help of the weight of the shaft-length of wall above its insertion, which is, of course, greater than the weight of the small shaft: and then the lower bracket may be farther helped by the structure at b or c.
