Fig. 162.—Plan of St. Mark’s at Venice.

The ground-plan of St. Mark’s (Fig. [162]) presents a Greek cross, i.e. one in which all the arms are equal, and it is roofed by five principal domes, one at the crossing and one over each of the four limbs of the cross. Aisles at a low level, and covered by a series of small flat domes, in lieu of vaulting, fill up the angles between the arms of the cross, so as to make the outline of the plan nearly square.

The rich colouring of St. Mark’s, due to a profuse employment of mosaics and of the most costly marbles, and the splendid effects produced by the mode of introducing light, which is admitted much as at Santa Sophia, are perhaps its greatest charm; but there is beauty in every aspect of its interior which has furnished a fit theme for the pen of the most eloquent writer on art and architecture of the present or perhaps of any day.

From Venice the influence of Byzantine art spread to a small extent in North Italy; in that city herself as well as in neighbouring towns, such as Padua, buildings and fragments of buildings exhibiting the characteristics of the style can be found. Remarkable traces of the influence of Byzantium as a centre, believed to be due to intercourse with Venice, can also be found in France. Direct communication with Constantinople by way of the Mediterranean has also introduced Byzantine taste into Sicily. One famous French church, St. Front in Périgueux, is identical (or nearly so) with St. Mark’s in its plan; but all its constructive arches being pointed (Fig. [3], page [5]), its general appearance differs a good deal from that of Eastern churches—a difference which is accentuated by the absence of the mosaics and other coloured ornaments which enrich the walls of St. Mark’s. Many very old domed churches and much sculpture of the Byzantine type are moreover to be found in Central and Southern France—Anjou, Aquitaine, and Auvergne. These are, however, isolated examples of the style having taken root in spite of adverse circumstances; it is in those parts of Europe where the Greek Church prevails, or did prevail, that Byzantine architecture chiefly flourishes. In Greece and Asia Minor many ancient churches of Byzantine structure remain, while in Russia churches are built to the present day corresponding to the general type of those which have just been described.
