38, the first time he saw such a roof; and the beauty of its traceries would be enhanced to him if they confessed and followed the lines of its main strength. If, however, the intermediate shell were made of wood instead of stone, and whitewashed to look like the rest—this would, of course, be direct deceit, and altogether unpardonable.

There, is, however, a certain deception necessarily occurring in Gothic architecture, which relates, not to the points, but to the manner, of support. The resemblance in its shafts and ribs to the external relations of stems and branches, which has been the ground of so much foolish speculation, necessarily induces in the mind of the spectator a sense or belief of a correspondent internal structure; that is to say, of a fibrous and continuous strength from the root into the limbs, and an elasticity communicated upwards, sufficient for the support of the ramified portions. The idea of the real conditions, of a great weight of ceiling thrown upon certain narrow, jointed lines, which have a tendency partly to be crushed, and partly to separate and be pushed outwards, is with difficulty received; and the more so when the pillars would be if unassisted, too slight for the weight, and are supported by external flying buttresses, as in the apse of Beauvais, and other such achievements of the bolder Gothic. Now, the is a nice question of conscience in this, which we shall hardly settle but by considering that, when the mind is informed beyond the possibility of mistake as to the true nature of things, the affecting it with a contrary impression, however distinct, is no dishonesty, but on the contrary, a legitimate appeal to the imagination. For instance, the greater part of the happiness which we have in contemplating clouds, results from the impression of their having massive, luminous, warm, and mountain-like surfaces; and our delight in the sky frequently depends upon our considering it as a blue vault. But if we choose, we may know the contrary, in both
