The stages of the progress of the Renaissance are visible, in following the history of art, from Benci di Cione, to Brunellesco, from Orcagna and Alberto d’Arnoldo to Ghiberti and Donatello, from Orcagna again, Spinello, and Nicolò di Pietro, to Masolino and Masaccio. In the province of architecture, classical art entered again upon its rights under the influence of the new spirit. Brunellesco, who, while in his native town, had fixed his attention on Roman edifices, accustomed his eye when in Rome to the large dimensions and simple yet harmonious forms of ancient art. The Italian Gothic, which is not of one cast, but more or less dependent upon the older forms of art, must, in comparison with the latter, appear arbitrary in its character. Yet the classical principle obtained by no means an easy victory. The greatest work of the period, the dome of Sta. Maria del Fiore, is the result of a compromise, which under the circumstances was unavoidable, between the traditions of two epochs, and between the characters of two different tendencies. The requirements both of a strict division and demarcation of masses, and the perception of grand beauty and ample space had also to be reconciled. So in other branches of art the Gothic style asserted itself for a length of time by the side of the new tendency. In February 1393 a commission was first appointed for the building of the dome, the sacristy, and the canonica of the cathedral.[33] But it was a full quarter of a century before the work was fairly begun. On August 19, 1418, the famous competition, which has since been celebrated in a novel, was invited for models of the dome. On November 14, 1419, a commission of ‘Officiales Cupolæ’ was appointed, consisting of four of the principal citizens. April 16, 1420, the office of _Proveditores_ was conferred on Filippo Brunelleschi, Lorenzo Ghiberti and Battista d’Antonio; and on August 12, 1434, it was resolved that the lantern with which the dome was to be closed should be built after Brunellesco’s model. The lantern was, however, only completed in 1462, sixteen years after the great artist’s death.[34] The greatest and most complex work of modern architecture belongs consequently to the time when the Albizzis held power. Meanwhile many other buildings were undertaken. In 1411 an illustrious citizen, Nicolò Davanzati Bostichi, began the construction of the convent S. Michele of Doccia, near Fiesole, which, built against the dark background of the wooded hillside, can be seen far and wide. In 1416 the plan for the rebuilding of San Lorenzo was sketched out; in 1421 the great foundling hospital of the Innocents, with its beautiful portico on the Piazzi of the Annunziata, was begun; and twelve years later Sto. Spirito, the two latter after Brunellesco’s designs. Notwithstanding some defects, owing chiefly to the difficulty, imperfectly surmounted, of continuing the colonnade from the nave through the transept and choir, and to the
