n doorways and apertures of windows. Thus, the whole body of the
Northern architecture, represented by that of the Lombards, may be
described as rough but majestic work, round-arched, with grouped shafts,
added vaulting shafts, and endless imagery of active life and fantastic
superstitions.

Sec. XXIX. The glacier stream of the Lombards, and the following one of
the Normans, left their erratic blocks, wherever they had flowed; but
without influencing, I think, the Southern nations beyond the sphere of
their own presence. But the lava stream of the Arab, even after it
ceased to flow, warmed the whole of the Northern air; and the history of
Gothic architecture is the history of the refinement and
spiritualisation of Northern work under its influence. The noblest
buildings of the world, the Pisan-Romanesque, Tuscan (Giottesque)
Gothic, and Veronese Gothic, are those of the Lombard schools
themselves, under its close and direct influence; the various Gothics of
the North are the original forms of the architecture which the Lombards
brought into Italy, changing under the less direct influence of the
Arab.

Sec. XXX. Understanding thus much of the formation of the great European
styles, we shall have no difficulty in tracing the succession of
architectures in Venice herself. From what I said of the central
character of Venetian art, the reader is not, of course, to conclude
that the Roman, Northern, and Arabian elements met together and
contended for the mastery at the same period. The earliest element was
the pure Christian Roman; but few, if any, remains of this art exist at
Venice; for the present city was in the earliest times only one of many
settlements formed on the chain of marshy islands which extend from the
mouths of the Isonzo to those of the Adige, and it was not until the
beginning of the ninth century that it became the seat of government;
while the cathedral of Torcello, though Christian Roman in general form,
was rebuilt in the eleventh century, and shows evidence of Byzantine
workmanship in many of its details. This cathedral, however, with the
church of Santa Fosca at Torcello, San Giacomo di Rialto at Venice, and
the crypt of St. Mark's, forms a distinct group of buildings, in which
the Byzantine influence is exceedingly slight; and which is probably
very sufficiently representative of the earliest architecture on the
islands.

Sec. XXXI. The Ducal residence was removed to Venice in 809, and the
body o
