Among the best examples of medieval Italian sculpture
The Fontana Maggiore was created between 1278 and 1280 by Nicola and Giovanni Pisano to celebrate the completion of the new aqueduct. It was designed by Friar Bevignate, with the aid, for the hydraulic side, of Boninsegna from Venice.
It consists of two concentric polygonal basins, decorated with 50 bas-reliefs and 24 statues. The lower basin goes to relief scenes of the agrarian tradition, the months of the year with the zodiac signs, of the liberal arts, the Bible and the history of Rome. The upper tank is made up of twenty-four plates, separated by statues of allegorical and historical sacred figures.
The two basins are surmounted by a bronze cup, in turn crowned by a group of three "nymphs" who represent the three theological virtues (Faith, Hope, Charity).
