At the top of the picturesque and richly ornamented staircase, to the right of the loggia on the first floor, opens a great vaulted hall, where the works of Donatello, casts and originals, surround a cast of his great equestrian monument to Gattamelata at Padua--a hall of such noble proportions that even Gattamelata looks insignificant, where he sits his war-horse between the Cross of the People and the Lily of the Commune. Here the general council of the Commune met--the only council (besides the special council of the Podestà) in which the magnates could sit and vote, and it was here, on July 6th, 1295, that Dante Alighieri first entered public life; he spoke in support of the modifications of the Ordinances of Justice--which may have very probably been a few months before he definitely associated himself with the People by matriculating in the Arte dei Medici e Speziali. Among the casts and copies that fill this room, there are several original and splendid works of Donatello; the Marzocco, or symbolical lion of Florence protecting the shield of the Commune, which was formerly in front of the Palace of the Priors; the bronze David, full of Donatello's delight in the exuberance of youthful manhood just budding; the San Giovannino or little St. John; the marble David, inferior to the bronze, but heralding Michelangelo; the bronze bust of a youth, called the son of Gattamelata; Love trampling upon a snake (bronze); St. George in marble from Or San Michele, an idealised condottiere of the Quattrocento; St. John the Baptist from the Baptistery; and a bronze relief of the Crucifixion. The coloured bust is now believed by many critics to be neither the portrait of Niccolò da Uzzano nor by Donatello; it is possibly a Roman hero by some sculptor of the Seicento.
