Cimabue's last work is said to be a figure, which was left unfinished, of S. John, in mosaic, for the Duomo at Pisa. This was in 1302, which is supposed to be the date of his death, though Vasari puts it two years earlier, at the time he was engaged with the architect Arnolfo Lapi in superintending the building of the Duomo in Florence, where he is buried. II GIOTTO DI BONDONE While according all due honour, and probably more, to Cimabue as the originator of modern painting, it is to his pupil, GIOTTO, that we are accustomed to look for the first developments of its possibilities. Had Cimabue's successors been as conservative as his instructors, we might still be not very much better off than if he had never lived. For much as there is to admire in Cimabue's painting, it is only the first flush of the dawn which it heralded, and though containing the germ of the future development of the art, is yet without any of the glory which in the fulness of time was to result from it. To Giotto, Vasari considers, "is due the gratitude which the masters in painting owe to Nature, seeing that he alone succeeded in resuscitating art and restoring her to a path that may be called the true one; and that the art of design, of which his contemporaries had little if any knowledge, was by his means effectually recalled to life." This seems to detract in some degree from his eulogies of Cimabue; but it is to the last sentence that our attention should be directed, which implies that in profiting by the master's example he succeeded in extending the possibilities of the new art beyond its first limits. Cimabue, we may believe, drew his Virgins and Saints from living models, whereas his predecessors had merely repeated formulas laid down for them by long tradition. Giotto went further, and extended his scope to the world at large. For the plain gold background he substituted the landscape, thus breaking down, as it were, a great wall, and seeing beyond it. Nor was this innovation merely a technical one--it was the man's nature that effected it and made his art a living thing. Giotto, who was born in 1276, was the son of a simple husbandman, who lived at Vespignano, about fourteen miles from Florence. Cimabue chanced upon the boy when he was only about ten years old, tending his father's sheep, and was astonished to find that he was occupied in making a drawing of one of them upon a smooth piece of rock with a sharp stone. He was so pleased with this that he asked to be allowed to take him back to Florence, and the boy proved so apt a pupil that before very long he was regularly employed in painting.
