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 strokes that I made with my own brush?" "You have forgotten them," said Giorgio, "for this picture is by the hand of Andrea del Sarto; and to prove it, there is a sign (to which he pointed) that was made in Florence, because when the two were together they could not be distinguished." Hearing this, Giulio had the picture turned round, and saw the mark; at which he shrugged his shoulders and said these words, "I value it no less than if it were by the hand of Raffaello—nay, even more, for it is something out of the course of nature that a man of excellence should imitate the manner of another so well, and should make a copy so like. It is enough that it should be known that Andrea's genius was as valiant in double harness as in single." Thus, then, by the wise judgment of Messer Ottaviano, satisfaction was given to the Duke without depriving Florence of so choice a work, which, having been presented to him afterwards by Duke Alessandro, he kept in his possession for many years; and finally he gave it to Duke Cosimo, who has it in his guardaroba together with many other famous pictures.
While Andrea was making this copy, he also painted for the same Messer Ottaviano a picture with only the head of Cardinal Giulio de' Medici, who afterwards became Pope Clement; and this head, which was similar to that by Raffaello, and very beautiful, was presented eventually by Messer Ottaviano to old Bishop de' Marzi.
Not long after, Messer Baldo Magini of Prato desiring to have a most beautiful panel-picture painted for the Madonna delle Carcere in his native city, for which he had already caused a very handsome ornament of marble to be made, one of the many painters proposed to him was Andrea. Wherefore Messer Baldo, having more inclination for him than for any of the others, although he had no great understanding in such a matter, had almost given him to believe that he and no other should do the work, when a certain Niccolò Soggi of Sansovino, who had some interest at Prato, was suggested to Messer Baldo for the undertaking, and assisted to such purpose by the assertion that there was not a better master to be found, that the work was given to him. Meanwhile, Andrea's supporters sending for him, he, holding it as settled that the work was to be his, went off to Prato with Domenico Puligo and other painters who were his friends. Arriving there, he found that Niccolò not only had persuaded Messer Baldo to change his mind, but also was bold and shameless enough to say to him in the presence of Messer Baldo that he would compete with Andrea for a bet of any sum of money in painting something, the winner to take the whole. Andrea, who knew what Niccolò was worth, answered, although he was generally a man of little spirit, "Here is my assistant, who has not been long in our art. If you will bet with him, I will put down the money for him; but with me you shall have no bet for any money in the world, seeing that, if I were to beat you, it would do me no honour, and if I were to lose, it would be the greatest possible disgrace." And, saying to Messer Baldo that he should give the work to Niccolò, because he would execute it in such a manner as would please the folk that went to market, he returned to Florence.
There he was commissioned to paint a panel for Pisa, divided into five pictures, which were afterwards placed round the Madonna of S. Agnese, beside the walls of that city, between the old Citadel and the Duomo. Making one figure, then, in each picture, he painted in two of them S. John the Baptist and S. Peter, one on either side of the Madonna that works miracles; and in the others are S. Catharine the Martyr, S. Agnese, and S. Margaret, each a figure by itself, and all so beautiful as to fill with marvel anyone who beholds them, and considered to be the most gracious and lovely women that he ever painted.
M. Jacopo, a Servite friar, in releasing and absolving a woman from a vow, had told her that she must have a figure of Our Lady painted over the outer side of that lateral door of the Nunziata which leads into the cloister; and therefore, finding Andrea, he said to him that he had this money to spend, and that although it was not much it seemed to him right, since the other works executed by Andrea in that place had brought him such fame, that he and no other should paint this one as well. Andrea, who was nothing if not an amiable man, moved by the persuasions of the friar and by his own desire for profit and glory, answered that he would do it willingly; and shortly afterwards, putting his hand to the work, he painted in fresco a most beautiful Madonna seated with her Son in her arms, and S. Joseph leaning on a sack, with his eyes fixed upon an open book. And of such a kind was this work, in draughtsmanship, grace, and beauty of colouring, as well as in vivacity and relief, that it proved that he outstripped and surpassed by a great measure all the painters who had worked up to that time. Such, indeed, is this picture, that by its own merit and without praise from any other quarter it makes itself clearly known as amazing and most rare.
There was wanting only one scene in the cloister of the Scalzo for it to be completely finished; wherefore Andrea, who had added grandeur to his manner after having seen the figures that Michelagnolo had begun and partly finished for the Sacristy of S. Lorenzo, set his hand to executing this last scene. In this, giving the final proof of his improvement, he painted the Birth of S. John the Baptist, with figures that were very beautiful and much better and stronger in relief than the others made by him before in the same place. Most beautiful, among others in this work, are a woman who is carrying the newborn babe to the bed on which lies S. Elizabeth, who is likewise a most lovely figure, and Zacharias, who is writing on a paper that he has placed on his knee, holding it with one hand and with the other writing the name of his son, and all with such vivacity, that he lacks nothing save the breath of life. Most beautiful, also, is an old woman who is seated on a stool, smiling with gladness at the delivery of the other aged woman, and revealing in her attitude and expression all that would be seen in a living person after such an event.
Having finished that work, which is certainly well worthy of all praise, he painted for the General of Vallombrosa a panel-picture with four very lovely figures, S. John the Baptist, S. Giovanni Gualberto, founder of that Order, S. Michelagnolo, and S. Bernardo, a Cardinal and a monk of the Order, with some little boys in the centre that could not be more vivacious or more beautiful. This panel is at Vallombrosa, on the summit of a rocky height, where certain monks live in some rooms called "the cells," separated from the others, and leading as it were the lives of hermits.
After this he was commissioned by Giuliano Scala to paint a panel-picture, which was to be sent to Serrazzana, of a Madonna seated with the Child in her arms, and two half-length figures from the knees upwards, S. Celso and S. Julia, with S. Onofrio, S. Catharine, S. Benedict, S. Anthony of Padua, S. Peter, and S. Mark; which panel was held to be equal to the other works of Andrea. And in the hands of Giuliano Scala, in place of the balance due to him of a sum of money that he had paid for the owners of that work, there remained a lunette containing an Annunciation, which was to go above the panel, to complete it; and it is now in his chapel in the great tribune round the choir of the Church of the Servi.
The Monks of S. Salvi had let many years pass by without thinking of having a beginning made with their Last Supper, which they had commissioned Andrea to execute at the time when he painted the arch with the four figures; but finally an Abbot, who was a man of judgment and breeding, determined that he should finish that work. Thereupon Andrea, who had already pledged himself to it on a previous occasion, far from making any demur, put his hand to the task, and, working at it one piece at a time when he felt so inclined, finished it in a few months, and that in such a manner, that the work was held to be, as it certainly is, the most spontaneous and the most vivacious in colouring and drawing that he ever made, or that ever could be made. For, among other things, he gave infinite grandeur, majesty, and grace to all the figures, insomuch that I know not what to say of this Last Supper that would not be too little, it being such that whoever sees it is struck with amazement. Wherefore it is no marvel that on account of its excellence it was left standing amid the havoc of the siege of Florence, in the year 1529, at which time the soldiers and destroyers, by command of those in authority, pulled down all the suburbs without the city, and all the monasteries, hospitals, and other buildings. These men, I say, having destroyed the Church and Campanile of S. Salvi, and beginning to throw down part of the convent, had come to the refectory where this Last Supper is, when their leader, seeing so marvellous a painting, of which he may have heard speak, abandoned the undertaking and would not let any more of that place be destroyed, reserving the task until such time as there should be no alternative.
