The art which came to maturity in the late fifteenth and early sixteenth centuries was generated in the early mediæval revival. The seeds may, indeed, have come down from antiquity, but they remained for nearly a thousand years hidden in the withered, rotting remains of former vegetation, and it was not till that vegetation had completely decomposed and become part of the soil, it was not till putrefaction had turned into germination, that artistic organism timidly reappeared. The new art-germ developed with the new civilization which surrounded it. Manufacture and commerce reappeared: the artisans and merchants formed into communities; the communities grew into towns, the towns into cities; in the city arose the cathedral; the Lombard or Byzantine mouldings and traceries of the cathedral gave birth to figure-sculpture; its mosaics gave birth to painting; every forward movement of the civilization unfolded as it were a new form or detail of the art, until, when mediæval civilization was reaching its moment of consolidation, when the cathedrals of Lucca and Pisa stood completed, when Niccoto and Giovanni Pisani had sculptured their pulpits and sepulchres, painting, in the hands of, Cimabue and Duccio, of Giotto and of Guido da Siena, freed itself from the tradition of the mosaicists as sculpture had freed itself from the practice of the stone-masons, and stood forth an independent and organic art. Thus painting was born of a new civilization, and grew by its own vital force; a thing of the Middle Ages, original and spontaneous. But contemporaneous with the mediæval revival was the resuscitation of antiquity; in proportion as the new civilization developed, the old civilization was exhumed; real Latin began to be studied only when real Italian began to be written; Dante, Petrarca, and Boccaccio were at once the founders of modern literature and the exponents of the literature of antiquity; the strong young present was to profit by the experience of the past.
