That work finished, after the Cardinal had made Giovanni a Chevalier of S. Pietro, he sent him to Florence, to the end that, when a certain chamber had been made in the Palace of the Medici (at that corner, namely, where the elder Cosimo, the builder of that edifice, had made a loggia for the convenience and assemblage of the citizens, as it was the custom at that time for the most noble families to do), he might paint and adorn it all with grotesques and stucco. That loggia having then been enclosed after the design of Michelagnolo Buonarroti, and given the form of a chamber, with two knee-shaped windows, which were the first to be made in that manner, with iron gratings, for the exterior of a palace, Giovanni adorned all the vaulting with stucco-work and painting, making in a medallion the six balls, the arms of the House of Medici, supported by three little boys executed in relief in attitudes of great beauty and grace. Besides this, he made there many most beautiful animals, and also many most lovely devices of gentlemen and lords of that illustrious house, together with some scenes in half-relief, executed in stucco; and on the field of the vaulting he did the rest of the work in pictures, counterfeiting them after the manner of cameos in black and white, and so well, that nothing better could be imagined. There remained four arches beneath the vaulting, each twelve braccia in breadth and six in height, which were not painted at that time, but many years afterwards by Giorgio Vasari, as a young man of eighteen years, when he was in the service of Duke Alessandro de' Medici, his first lord, in the year 1535; which Giorgio executed there stories from the life of Julius Caesar, in allusion to the above-named Cardinal Giulio, who had caused the work to be done. Giovanni then executed on a little barrel-shaped vault, beside that chamber, some works in stucco in the lowest of low-relief, and likewise some pictures, which are exquisite; but, although these pleased the painters that were in Florence at that time, being wrought with boldness and marvellous mastery, and filled with spirited and fantastic inventions, yet, since they were accustomed to a laboured manner of their own and to doing everything that they carried into execution with copies taken from life, they did not praise them without reserve, not being altogether decided in their minds, nor did they set themselves to imitate them, perhaps because they had not the courage.
