The great contributions made by Fra Bartolommeo to the art of Italy were in the double region of composition and colouring. In his justly celebrated fresco of S. Maria Nuova at Florence--a "Last Judgment" with a Christ enthroned amid a choir of Saints--he exhibited for the first time a thoroughly scientific scheme of grouping based on geometrical principles. Each part is perfectly balanced in itself, and yet is necessary to the structure of the whole. The complex framework may be subdivided into numerous sections no less harmoniously ordered than is the total scheme to which they are subordinated. Simple figures--the pyramid and the triangle, upright, inverted, and interwoven like the rhymes in a sonnet--form the basis of the composition. This system was adhered to by the Frate in all his subsequent works. To what extent it influenced the style of Raphael, will be afterwards discussed. As a colourist, Fra Bartolommeo was equal to the best of his contemporaries, and superior to any of his rivals in the school of Florence. Few painters of any age have combined harmony of tone so perfectly with brilliance and richness. It is a real joy to contemplate the pure and splendid folds of the white drapery he loved to place in the foreground of his altar-pieces. Solidity and sincerity distinguish his work in every detail, while his feeling is remarkable for elevation and sobriety. All that he lacks, is the boldness of imagination, the depth of passion, and the power of thought, that are indispensable to genius of the highest order. Gifted with a sympathetic and a pliant, rather than a creative and self-sustained nature, he was sensitive to every influence. Therefore we find him learning much in his youth from Lionardo, deriving a fresh impulse from Raphael, and endeavouring in his later life, after a visit to Rome in 1514, to "heighten his style," as the phrase went, by emulating Michael Angelo. The attempt to tread the path of Buonarroti was a failure. What Fra Bartolommeo sought to gain in majesty, he lost in charm. His was essentially a pure and gracious manner, upon which sublimity could not be grafted. The gentle soul, who dropped his weapon when the convent of S. Marco was besieged by the Compagnacci[229], and who vowed, if heaven preserved him in the tumult, to become a monk, had none of Michael Angelo's _terribilità_. Without possessing some share of that spirit, it was vain to aggrandise the forms and mass the raiment of his prophets in imitation of the Sistine.
