That traitor to his country, Ridolfo Varano, Captain-General of the Republic during the war with Gregory IX., who went over to the Pope, was also figured, hung by the feet, in 1377, not only on the tower of the palace, but on the gates of the town. But when peace was made with Urban VI., the painting was effaced. Eleven years later Bonaccorso di Lapo Giovanni, who had been three times a Prior and twice Gonfalonier of Justice, intrigued with Gian Galeazzo Visconti against the Republic, and was condemned to death _in contumaciam_. As a warning to all traitors his effigy was painted at the foot of the tower of the Palazzo del Podestà, hung in chains and surrounded with devils.[67] The old palace must have been covered with these ghastly frescoes when, at the instigation of Cosimo de’ Medici, Albizzi, Peruzzi and Strozzi, who had taken up arms to oppose his return to Florence in 1434, were also gibbeted as traitors to their country. Nearly fifty years later, after the conspiracy of the Pazzi, Vasari tells us: “the Signori passed a resolution that the portraits of all those concerned in the conspiracy should be painted on the façade of the Palazzo del Podestà. The work was offered to Andrea del Castagno who, as a servant of the house of Medici and much indebted to them, willingly accepted the commission and performed it so well that it was a marvel. It is impossible to describe the art and the judgment displayed in these figures which were nearly the size of life, hanging by their feet in strange attitudes, all varied and of great beauty. This work was so pleasing to the whole city, particularly to those who were learned in the art of painting, that Andrea was ever after called Andrea degli impiccati (of the hanged), instead of by his own name Andrea del Castagno.” In 1480, when peace was made with Sixtus IV., these paintings were effaced, as amongst them were his nephew Girolamo Riario, Francesco Salviati, Archbishop of Pisa, and a priest, Stefano di Bagnone. Fourteen years later, when the Medici were driven out of Florence, the portraits of Albizzi, Peruzzi and Strozzi were also destroyed.
