"To his new charge," writes Mr. C. E. Norton, "Giotto gave himself with the effectual ardor of genius. No written record of his work on the Duomo remains, but the walls themselves seem to bear witness to it. Stretches on the north and south, running eastward from the façade, more beautiful in composition and design than the later work joined to it, may be assigned with probability to the period of his oversight.

"But Giotto's labor was not limited to the Duomo alone. He now designed and speedily began the construction of the most exquisite building of modern times, the one in which the quality of classic art is most completely and beautifully harmonized with the spirit and fancy of modern times. The unsurpassed bell-tower of the Duomo, known and admired by all men as the Campanile of Giotto, is the most splendid memorial of the arts of Florence. In 1334, scarcely three months after his appointment, the foundations of the Campanile were laid with great pomp and ceremony. The tower, so quickly begun, was so vigorously lifted that it may have reached somewhat more than a third of its proposed height, when in 1337 Giotto died." He was buried in the unfinished Cathedral on the side nearest the Campanile.

"In its first appeal to the stranger's eye," says Mr. Ruskin in writing of the Campanile, "there is something unpleasing; a mingling, it seems to him, of over severity with over minuteness. But let him give it time, as he should all other consummate art. I remember well how, when a boy, I used to despise that Campanile, and think it meanly smooth and finished. But I have since lived beside it many a day, and looked out upon it from my windows by sunlight and moonlight, and I shall not soon forget how profound and gloomy appeared to me the savageness of the Northern Gothic when I afterwards stood, for the first time, beneath the front of Salisbury. The contrast is indeed strange, if it could be quickly felt, between the rising of those gray walls out of their quiet swarded space, like dark and barren rocks out of a green lake, and that bright, smooth, sunny surface of glowing jasper, those spiral shafts and fairy traceries, so white, so faint, so crystalline, that their slight shapes are hardly traced in darkness on the pallor of the eastern sky, that serene height of mountain alabaster, colored like a morning cloud and chased like a sea shell. And this, I believe to be the model and mirror of perfect architecture...."

PLATE XLVREAR OF THE DUOMO

"Considerable size exhibited by simple terminal lines; projection towards the top; breadth of flat surface; square compartments of that surface; varied and visible masonry; vigorous depth of shadow, exhibited especially by pierced traceries; varied proportion in ascent; lateral symmetry; sculpture most delicate at the base; enriched quantity of ornament at the top; sculpture abstract in inferior ornaments and mouldings, complete in animal forms, both to be executed in white marble; vivid colors introduced in flat geometrical patterns, and obtained by the use of naturally colored stone,—these characteristics occur more or less in different buildings, some in one, some in another—but all together and all in their highest possible relative degrees, they exist, as far as I know, only in one building in the world, the Campanile of Giotto."
