Now Federigo II, Duke of Mantua, in passing through Florence on his way to make obeisance to Clement VII, saw over a door in the house of the Medici that portrait of Pope Leo between Cardinal Giulio de' Medici and Cardinal de' Rossi, which the most excellent Raffaello da Urbino had formerly painted; and being extraordinarily pleased with it, he resolved, being a man who delighted in pictures of such beauty, to make it his own. And so, when he was in Rome and the moment seemed to him to have come, he asked for it as a present from Pope Clement, who courteously granted his request. Thereupon orders were sent to Florence to Ottaviano de' Medici, under whose care and government were Ippolito and Alessandro, that he should have it packed up and taken to Mantua. This matter was very displeasing to the Magnificent Ottaviano, who would never have consented to deprive Florence of such a picture, and he marvelled that the Pope should have given it up so readily. However, he answered that he would not fail to satisfy the Duke; but that, since the frame was bad, he was having a new one made, and when it had been gilt he would send the picture with every possible precaution to Mantua. This done, Messer Ottaviano, in order to "save both the goat and the cabbage," as the saying goes, sent privately for Andrea and told him how the matter stood, and how there was no way out of it but to make an exact copy of the picture with the greatest care and send it to the Duke, secretly retaining the one by the hand of Raffaello. Andrea, then, having promised to do all in his power and knowledge, caused a panel to be made similar in size and in every respect, and painted it secretly in the house of Messer Ottaviano. And to such purpose did he labour, that when it was finished even Messer Ottaviano, for all his understanding in matters of art, could not tell the one from the other, nor distinguish the real and true picture from the copy; especially as Andrea had counterfeited even the spots of dirt, exactly as they were in the original. And so, after they had hidden the picture of Raffaello, they sent the one by the hand of Andrea, in a similar frame, to Mantua; at which the Duke was completely satisfied, and above all because the painter Giulio Romano, a disciple of Raffaello, had praised it, failing to detect the trick. This Giulio would always have been of the same opinion, and would have believed it to be by the hand of Raffaello, but for the arrival in Mantua of Giorgio Vasari, who, having been as it were the adoptive child of Messer Ottaviano, and having seen Andrea at work on that picture, revealed the truth. For Giulio making much of Vasari, and showing him, after many antiquities and paintings, that picture of Raffaello's, as the best work that was there, Giorgio said to him, "A beautiful work it is, but in no way by the hand of Raffaello." "What?" answered Giulio. "Should I not know it, when I recognize the very
