truly mediæval carver, animated with a Christian, instead of a Pagan spirit, but caring for the loveliness of form which art in the Dark Ages failed to realize. Whether it was Nicola or his sons who designed the bas-reliefs at Orvieto is of little consequence. Vasari ascribes them to the father; but we know that he completed his pulpit at Pisa in 1230, and his death is supposed to have taken place fifteen years before the foundation of the Cathedral. At any rate, they are imbued with his genius, and bear the strongest affinity to his sculptures at Pisa, Siena, and Bologna. To estimate the influence they exercised over the arts of sculpture and painting in Italy would be a difficult task. Duccio and Giotto studied here; Ghiberti closely followed them. Signorelli and Raphael made drawings from their compositions. And the spirit which pervades these sculptures may be traced in all succeeding works of art. It is not classic; it is modern, though embodied in a form of beauty modelled on the Greek. The bas-reliefs are carved on four marble tablets placed beside the porches of the church, and corresponding in size and shape with the chief doorways. They represent the course of Biblical history, beginning with the creation of the world, and ending with the Last Judgment. If it were possible here to compare them in detail with the similar designs of Ghiberti, Michel Angelo, and Raphael, it might be shown that the Pisani established modes of treating sacred subjects from which those mighty masters never deviated, though each stamped upon them his peculiar genius, making them more perfect as time added to the power of art. It would also be not without interest to show that in their primitive conceptions of the earliest events in history, the works of the Pisan artists closely resemble some sculptures executed on the walls of Northern cathedrals, as well as early mosaics in the south of Italy. We might have noticed how all the grotesque elements which appear in Nicola Pisano, and which may still be traced in Ghiberti, are entirely lost in Michel Angelo, how the supernatural is humanized, how the symbolical receives an actual expression, and how intellectual types are substituted for mere local and individual representations. For instance, the Pisani represent the Creator as a young man, standing on the earth, with a benign and dignified expression, and attended by two ministering angels. He is the Christ of the Creed, “by whom all things were made.” In Ghiberti we find an older man, sometimes appearing in a whirlwind of clouds and attendant spirits, sometimes walking on the earth, but still far different in conception from the Creative Father of Michel Angelo. The latter is rather the Platonic Demiurgus than the Mosaic God. By every line and feature of his face and flowing hair, by each movement of his limbs, whether he ride on clouds between the waters and the firmament, or stand alone creating by
