§ V. But, as alternating with the recess, it has a decoration peculiar to itself. We have often, in the preceding chapters, noted the fondness of the Northern builders for deep shade and hollowness in their mouldings; and in the second chapter of the "Seven Lamps," the changes are described which reduced the massive roll mouldings of the early Gothic to a series of recesses, separated by bars of light. The shape of these recesses is at present a matter of no importance to us: it was, indeed, endlessly varied; but needlessly, for the value of a recess is in its darkness, and its darkness disguises its form. But it was not in mere wanton indulgence of their love of shade that the Flamboyant builders deepened the furrows of their mouldings: they had found a means of decorating those furrows as rich as it was expressive, and the entire frame-work of their architecture was designed with a view to the effect of this decoration; where the ornament ceases, the frame-work is meagre and mean: but the ornament is, in the best examples of the style, unceasing. § VI. It is, in fact, an ornament formed by the ghosts or anatomies of the old shafts, left in the furrows which had taken their place. Every here and there, a fragment of a roll or shaft is left in the recess or furrow: a billet-moulding on a huge scale, but a billet-moulding reduced to a skeleton; for the fragments of roll are cut hollow, and worked into mere entanglement of stony fibres, with the gloom of the recess shown through them. These ghost rolls, forming sometimes pedestals, sometimes canopies, sometimes covering the whole recess with an arch of tracery, beneath which it runs like a tunnel, are the peculiar decorations of the Flamboyant Gothic. § VII. Now observe, in all kinds of decoration, we must keep carefully under separate heads, the consideration of the changes wrought in the mere physical form, and in the intellectual purpose of ornament. The relations of the canopy to the statue it shelters, are to be considered altogether distinctly from those of the canopy to the building which it decorates. In its earliest conditions the canopy is partly confused with representations of miniature architecture: it is sometimes a small temple or gateway, sometimes a honorary addition to the pomp of a saint, a covering to his throne, or to his shrine; and this canopy is often expressed in bas-relief (as in painting), without much reference to the great requirements of the building. At other times it is a real protection to the statue, and is enlarged into a complete pinnacle, carried on proper shafts, and boldly roofed. But in the late northern system the canopies are neither expressive nor protective. They are a kind of stone lace-work, required for the ornamentation of the building, for which the statues are often little more than an excuse, and of which the physical character is, as above described, that of ghosts of departed shafts.
