B. _Greater breadth of mass._ It had been the habit of the Byzantines to break up their draperies by a large number of minute folds. Norman and Romanesque sculpture showed much of the same character. Giotto melted all these folds into broad masses of colour; so that his compositions have sometimes almost a Titianesque look in this particular. This innovation was a healthy one, and led to very noble results when followed up by succeeding artists: but in many of Giotto's compositions the figures become ludicrously cumbrous, from the exceeding simplicity of the terminal lines, and massiveness of unbroken form. The manner was copied in illuminated manuscripts with great disadvantage, as it was unfavourable to minute ornamentation. The French never adopted it in either branch of art, nor did any other Northern school; minute and sharp folds of the robes remaining characteristic of Northern (more especially of Flemish and German) design down to the latest times, giving a great superiority to the French and Flemish illuminated work, and causing a proportionate inferiority in their large pictorial efforts. Even Rubens and Vandyke cannot free themselves from a certain meanness and minuteness in disposition of drapery. C. _Close imitation of nature._ In this one principle lay Giotto's great strength, and the entire secret of the revolution he effected. It was not by greater learning, not by the discovery of new theories of art, not by greater taste, nor by "ideal" principles of selection, that he became the head of the progressive schools of Italy. It was simply by being interested in what was going on around him, by substituting the gestures of living men for conventional attitudes, and portraits of living men for conventional faces, and incidents of every-day life for conventional circumstances, that he became great, and the master of the great. Giotto was to his contemporaries precisely what Millais is to _his_ contemporaries,--a daring naturalist, in defiance of tradition, idealism, and formalism. The Giottesque movement in the fourteenth, and Pre-Raphaelite movement in the nineteenth centuries, are precisely similar in bearing and meaning: both being the protests of vitality against mortality, of spirit against letter, and of truth against tradition: and both, which is the more singular, literally links in one unbroken chain of feeling; for exactly as Niccola Pisano and Giotto were helped by the classical sculptures discovered in their time, the Pre-Raphaelites have been helped by the works of Niccola and Giotto at Pisa and Florence: and thus the fiery cross of truth has been delivered from spirit to spirit, over the dust of intervening generations.
