+CHARACTER OF THE ARCHITECTURE.+ Romanesque architecture was pre-eminently ecclesiastical. Civilization and culture emanated from the Church, and her requirements and discipline gave form to the builder’s art. But the basilican style, which had so well served her purposes in the earlier centuries and on classic soil, was ill-suited to the new conditions. Corinthian columns, marble incrustations, and splendid mosaics were not to be had for the asking in the forests of Gaul or Germany, nor could the Lombards and Ostrogoths in Italy or their descendants reproduce them. The basilican style was complete in itself, possessing no seeds of further growth. The priests and monks of Italy and Western Europe sought to rear with unskilled labor churches of stone in which the general dispositions of the basilica should reappear in simpler, more massive dress, and, as far as possible, in a fireproof construction with vaults of stone. This problem underlies all the varied phases of Romanesque architecture; its final solution was not, however, reached until the Gothic period, to which the Romanesque forms the transition and stepping-stone. +MEDIÆVAL ITALY.+ Italy in the Dark Ages stood midway between the civilization of the Eastern Empire and the semi-barbarism of the West. Rome, Ravenna, and Venice early became centres of culture and maintained continuous commercial relations with the East. Architecture did not lack either the inspiration or the means for advancing on new lines. But its advance was by no means the same everywhere. The unifying influence of the church was counterbalanced by the provincialism and the local diversities of the various Italian states, resulting in a wide variety of styles. These, however, may be broadly grouped in four divisions: the +Lombard+, the +Tuscan-Romanesque+, the +Italo-Byzantine+, and the unchanged +Basilican+ or Early Christian, which last, as was shown in Chapter X., continued to be practised in Rome throughout the Middle Ages.
