mouldings of a similar kind.[75] It occurs, I think, on one house in
Venice, in the Campo St. Polo; but the ordinary moulding, with light
incisions, is frequent in archivolts and architraves, as well as in the
roof cornices.

Sec. VIII. This being the simplest treatment of the pyramid, fig. 10, from
the refectory of Wenlock Abbey, is an example of the simplest decoration
of the recesses or inward angles between the pyramids; that is to say,
of a simple hacked edge like one of those in fig. 2, the _cuts_ being
taken up and decorated instead of the _points_. Each is worked into a
small trefoiled arch, with an incision round it to mark its outline, and
another slight incision above, expressing the angle of the first
cutting. I said that the teeth in fig. 7 had in distance the effect of a
zigzag: in fig. 10 this zigzag effect is seized upon and developed, but
with the easiest and roughest work; the angular incision being a mere
limiting line, like that described in Sec. IX. of the last chapter. But
hence the farther steps to every condition of Norman ornament are self
evident. I do not say that all of them arose from development of the
dogtooth in this manner, many being quite independent inventions and
uses of zigzag lines; still, they may all be referred to this simple
type as their root and representative, that is to say, the mere hack of
the Venetian gunwale, with a limiting line following the resultant
zigzag.

Sec. IX. Fig. 11 is a singular and much more artificial condition, cast
in brick, from the church of the Frari, and given here only for future
reference. Fig. 12, resulting from a fillet with the cuts on each of its
edges interrupted by a bar, is a frequent Venetian moulding, and of
great value; but the plain or leaved dogteeth have been the favorites,
and that to such a degree, that even the Renaissance architects took
them up; and the best bit of Renaissance design in Venice, the side of
the Ducal Palace next the Bridge of Sighs, owes great part of its
splendor to its foundation, faced with large flat dogteeth, each about a
foot wide in the base, with their points truncated, and alternating with
cavities which are their own negatives or casts.

Sec. X. One other form of the dogtooth is of great importance in northern
architecture, that produced by oblique cuts slightly curved, as in the
margin, Fig. LVI. It is susceptible of the most fantastic and endless
decoration; each of the resulting leaves b
