DECORATION XXIII. THE EDGE AND FILLET 319

sides of the Atlantic;-in that rude Venetian gunwale, I say, is the germ of all the ornament which has touched, with its rich successions of angular shadow, the portals and archivolts of nearly every early building of importance, from the North Cape to the Straits of Messina. Nor are the modifications of the first suggestion intricate. All that is generic in their character may be seen on Plate 9 at a glance.

§ 4. Taking a piece of stone instead of timber, and enlarging the notches, until they meet each other, we have the condition 2, which is a moulding from the tomb of the Doge Andrea Dandolo, in St. Mark’s. Now considering this moulding as composed of two decorated edges, each edge will be reduced, by the meeting of the notches, to a series of four-sided pyramids (as marked off by the dotted lines), which, the notches here being shallow, will be shallow pyramids; but by deepening the notches, we get them as at 3, with the profile a, more or less steep. This moulding I shall always call “the plain dogtooth;” it is used in profusion in the Venetian and Veronese Gothic, generally set with its front to the spectator, as here at 3; but its effect may be much varied by placing it obliquely (4, and profile as at b); or with one side horizontal (5, and profile c). Of these three conditions, 3 and 5 are exactly the same in reality, only differently placed; but in 4 the pyramid is obtuse, and the inclination of its base variable, the upper side of it being always kept vertical. It is comparatively rare. Of the three, the last, 5, is far the most brilliant in effect, giving in the distance a zigzag form to the high light on it, and a full sharp shadow below. The use of this shadow is sufficiently seen by fig. 7 in this plate (the arch on the left, the number beneath it), in which these levelled dogteeth, with a small interval between each, are employed to set off by their vigour the delicacy of floral ornament above. This arch is the side of a niche from the tomb of Can Signorio della Scala, at Verona; and the value, as well as the distant expression of its dogtooth, may be seen by referring to Prout’s beautiful drawing of this tomb in
