As you enter the Loggia de' Lanzi, gay with children now, once the lounge of the Swiss Guard, whose barracks were not far away, you wonder who can have built so gay, so happy a place beside the fortress of the Signoria. Yet, in truth, it was for the Priori themselves that loggia was built, though not by Orcagna as it is said, to provide, perhaps, a lounge in summer for the fathers of the city, and for a place of proclamation that all Florence might hear the laws they had made. Yes, and to-day, too, do they not proclaim the tombola where once they announced a victory? Even now, in spite of forgotten greatness, it is still a garden of statues. Looking ever over the Piazza stands the Perseus of Cellini, with the head of Medusa held up to the multitude, the sword still gripped in his hand. It is the masterpiece of one who, like all the greatest artists of the Renaissance--Giotto, Orcagna, Leonardo, Michelangelo, Raphael--did not confine himself to one art, but practised many. And though it would be unjust to compare such a man as Cellini with the greatest of all, yet he was great not only as a sculptor and a goldsmith, but as a man of letters and as a man of the world. His Perseus, a little less than a demigod, is indeed not so lovely as the wax model he made for it, which is now in the Bargello; but in the gesture with which he holds out the severed head from him, in the look of secret delight that is already half remorseful for all that dead beauty, in the heroic grace with which he stands there after the murder, the dead body marvellously fallen at his feet, Cellini has proved himself the greatest sculptor of his time. That statue cost him dear enough, as he tells you in his Memoirs, but, as Gautier said, it is worth all it cost.
