SECTION 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. SECTION XXXI. The Ducal residence was removed to Venice in 809, and the body of St. Mark was brought from Alexandria twenty years later. The first church of St. Mark's was, doubtless, built in imitation of that destroyed at Alexandria, and from which the relics of the saint had been obtained. During the ninth, tenth, and eleventh centuries, the architecture of Venice seems to have been formed on the same model, and is almost identical with that of Cairo under the caliphs, [Footnote: Appendix 10, "Church of Alexandria."] it being quite immaterial whether the reader chooses to call both Byzantine or both Arabic; the workmen being certainly Byzantine, but forced to the invention of new forms by their Arabian masters, and bringing these forms into use in whatever other parts of the world they were employed. To this first manner of Venetian architecture, together with such vestiges as remain of the Christian Roman, I shall devote the first division of the following inquiry. The examples remaining of it consist of three noble churches (those of Torcello, Murano, and the greater part of St. Mark's), and about ten or twelve fragments of palaces. SECTION XXXII. To this style succeeds a transitional one, of a character much more distinctly Arabian: the shafts become more slender, and the arches consistently pointed, instead of round; certain other changes, not to be enumerated in a sentence, taking place in the capitals and mouldings. This style is almost exclusively secular. It was natural for the Venetians to imitate the beautiful details of the Arabian dwelling-house, while they would with reluctance adopt those of the mosque for Christian churches.
