Hence, if any superior mind arose in Byzantine art, it had before it models which suggested or recorded a perfection they did not themselves possess; and the superiority of the individual mind would probably be shown in a more sincere and living treatment of the subjects ordained for repetition by the canons of the schools. In the art of the Goth, the choice of subject was unlimited, and the style of design so remote from all perfection, as not always even to point out clearly the direction in which advance could be made. The strongest minds which appear in that art are therefore generally manifested by redundance of imagination, and sudden refinement of touch, whether of pencil or chisel, together with unexpected starts of effort or flashes of knowledge in accidental directions, gradually forming various national styles. Of these comparatively independent branches of art, the greatest is, as far as I know, the French sculpture of the thirteenth century. No words can give any idea of the magnificent redundance of its imaginative power, or of the perpetual beauty of even its smallest incidental designs. But this very richness of sculptural invention prevented the French from cultivating their powers of painting, except in illumination (of which art they were the acknowledged masters), and in glass-painting. Their exquisite gift of fretting their stone-work with inexhaustible wealth of sculpture, prevented their feeling the need of figure-design on coloured surfaces. The style of architecture prevalent in Italy at the same period, presented, on the contrary, large blank surfaces, which could only be rendered interesting by covering them with mosaic or painting. The Italians were not at the time capable of doing this for themselves, and mosaicists were brought from Constantinople, who covered the churches of Italy with a sublime monotony of Byzantine traditions. But the Gothic blood was burning in the Italian veins; and the Florentines and Pisans could not rest content in the formalism of the Eastern splendour. The first innovator was, I believe, Giunta of Pisa, the second Cimabue, the third Giotto; the last only being a man of power enough to effect a complete revolution in the artistic principles of his time.
