Thanks to the studios of Agnolo and Agostino, Siena, a small town which calls to mind the ancient Sicyone, so weak in a political point of view and yet so learned and polished, was for some time the rival of Pisa, up to the period when Florence absorbed the artistic splendour of the two cities. Florence, as the home of the Arts, became the centre of radiation, whence artists took their flight over the whole of Italy, and from Italy spread among all the nations of Europe. Towards the end of the thirteenth century, the churches of Florence, on which the fraternities combined their efforts, and some of the civil buildings of this rich and flourishing city, were filled with statues. The foundation of the municipal palace in 1282, and that of the cathedral in 1298, made these two wonderful edifices real museums of sculpture, in which, among the works of Eastern artists, those of Giovanni of Arezzo and Giotto are distinguished. Agostino and Agnolo of Pisa executed at that time some magnificent examples at Santa Maria in Orvieto, San Francisco in Bologna, and in the subterranean Church of Assisi, &c. Lastly, Andrea of Pisa, a contemporary of Giotto, as he died only in 1345, extracted from antiquity all that Christian sculpture could borrow from it; that is, he combined sublimity both of form and expression. At Pisa, the chancel of Santa Maria a Ponte; at Florence, the campanile and the high-altar of Santa Maria de’ Fiori, and a door of San Giovanni; in the Cathedral of Pistoia, the tomb of Cino, are all of them so many masterpieces; above which, however, the old Pisan master proudly classed the works of his son Nino. This young artist, who carved the monument of the Scaligers at Verona, became, in fact, the worthy follower of the school which recognised Andrea as its chief. Jacopo della Quercia and Niccolo Aretino enriched also with magnificent works the towns of Siena, Lucca, Bologna, Arezzo, and Milan, as well as Florence. But when, in 1424, the tomb closed over Jacopo della Quercia, the lofty destinies of the art seemed to come to a termination, and soon rapidly declined. In Venice, at the death of Filippo Calendario, which occurred in 1355, Italian sculpture had already lost much of its nobility and vigour of style.
