“The Christian basilica,” says M. Vaudoyer, in his learned treatise on architecture in France, “was most certainly an imitation of the heathen basilica; but it is of importance to observe that from one cause or another the Christians, in the construction of their basilicas, very soon substituted for the Grecian architecture of the ancient basilicas a system of arches reposing directly on isolated columns, which served as their supports; a perfectly new contrivance, of which there existed no previous example. This new mode of construction, which has generally been attributed to the want of skill in the builders of this period, or to the nature of the materials they had at their disposal, was, however, to become the fundamental principle of Christian art; a principle characterised by the breaking up of the range of arches, and by the abandonment of the system of rectilinear construction of the Greeks and Romans.
“Indeed, the arcade, which had become the dominant element of Roman architecture, had nevertheless remained subject to the proportions of the Greek orders, of which the entablature served as an indispensable accompaniment; and from this medley of elements so diverse was produced the mixed style which characterises the Greco-Roman architecture. But the Christians, in separating or breaking up the arcade, in abandoning the use of the ancient orders, and in making the column the real support of the arch, laid the foundations of a new style, which led to the exclusive employment of arches and vaults in Christian edifices. The Church of St. Sophia at Constantinople, built by Justinian in the middle of the sixth century, affords the most ancient example of this system of construction by arches and vaults in a Christian church of large dimensions.”
Transported to the East, the Latin style there assumed a new character, owing especially to the adoption and generalisation of the cupola, of which there were some examples in Roman architecture, but only as an accessory; whereas, in what is called Byzantine architecture, this form became dominant, and, as it were, fundamental; thus, at all periods and at each time that the architectural influence of the East made itself felt in the West, we see the cupola introduced into buildings. The Church of St. Vital at Ravenna affords, in its plan ([Fig. 296]) and in its general appearance, an example of this influence, which is quite Byzantine.
Edifices of Latin architecture, properly so called, are rare, we might almost say that they have all disappeared ([Figs. 297] and [298]); but if some churches in Rome, whose foundation dates back to the fifth and sixth centuries, can be considered as specimens of this first period of Christian art, it is in the arrangement of the plan much more than in the details of execution, which for a long subsequent time since have been united with the work of later periods.
In the days when Christianity was so triumphantly established as to have no fear nor scruple to utilise, in the construction of its churches, the ruins

of the ancient temples, it generally happened that the architect, conforming himself to new requirements, endeavoured, by a prudent return towards the traditions of the past, to avoid those striking incongruities which would have deprived of all their value the magnificent materials he had at his disposal. Hence arose a style still undecided; hence mixed creations, which it will suffice merely to mention. Then we must not forget—to say nothing of the case in which, as in the old Roman city, Christian basilicas might be built with the marble of heathen sanctuaries—the monuments of this same Rome were still the only models that presented themselves for imitation. Finally, for this architecture which the Christian religion was to create as its own, it was obvious there would be an infancy, an age of groping in the dark and of uncertainty; and at length that there should be a separation from the past, and a gradually experienced feeling of individual strength. ([Fig. 299].)
This infancy lasted about five or six centuries; for it was only about the year 1000 that the new style—which we see at first made up of “recollections” and weak innovations—assumed an almost determinate form. This is the period called Norman,[49] which, according to M. Vaudoyer, has left us some monuments that are “the noblest, the simplest, and the severest expression of the Christian temple.”
