With pencil and with palette hitherto
You made your art high Nature's paragon;
Nay more, from Nature her own prize you won,
Making what she made fair more fair to view
.

Now that your learned hand with labour new
Of pen and ink a worthier work hath done,
What erst you lacked, what still remained her own,
The power of giving life, is gained for you
.

If men in any age with Nature vied
In beauteous workmanship, they had to yield
When to the fated end years brought their name
.

You, re-illuming memories that died,
In spite of Time and Nature have revealed
For them and for yourself eternal fame
.

Vasari's official position at the ducal court of Florence brought him into frequent and personal relations with Cosimo de' Medici. The Duke had long been anxious to lure the most gifted of his subjects back to Florence; but Michelangelo, though he remained a loyal servant to the Medicean family, could not approve of Cosimo's despotic rule. Moreover, he was now engaged by every tie of honour, interest, and artistic ambition to superintend the fabric of S. Peter's. He showed great tact, through delicate negotiations carried on for many years, in avoiding the Duke's overtures without sacrificing his friendship. Wishing to found his family in Florence and to fund the earnings of his life there, he naturally assumed a courteous attitude. A letter written by the Bishop Tornabuoni to Giovanni Francesco Lottini in Rome shows that these overtures began as early as 1546. The prelate says the Duke is so anxious to regain "Michelangelo, the divine sculptor," that he promises "to make him a member of the forty-eight senators, and to give him any office he may ask for." The affair was dropped for some years, but in 1552 Cosimo renewed his attempts, and now began to employ Vasari and Cellini as ambassadors. Soon after finishing his Perseus, Benvenuto begged for leave to go to Rome; and before starting, he showed the Duke Michelangelo's friendly letter on the bust of Bindo Altoviti. "He read it with much kindly interest, and said to me: 'Benvenuto, if you write to him, and can persuade him to return to Florence, I will make him a member of the Forty-eight.' Accordingly I wrote a letter full of warmth, and offered in the Duke's name a hundred times more than my commission carried; but not wanting to make any mistake, I showed this to the Duke before I sealed it, saying to his most illustrious Excellency: 'Prince, perhaps I have made him too many promises.' He replied: 'Michel Agnolo deserves more than you have promised, and I will bestow on him still greater favours.' To this letter he sent no answer, and I could see that the Duke was much offended with him."

While in Rome, Cellini went to visit Michelangelo, and renewed his offers in the Duke's name. What passed in that interview is so graphically told, introducing the rustic personality of Urbino on the stage, and giving a hint of Michelangelo's reasons for not returning in person to Florence, that the whole passage may be transcribed as opening a little window on the details of our hero's domestic life:—

"Then I went to visit Michel Agnolo Buonarroti, and repeated what I had written from Florence to him in the Duke's name. He replied that he was engaged upon the fabric of S. Peter's, and that this would prevent him from leaving Rome. I rejoined that, as he had decided on the model of that building, he could leave its execution to his man Urbino, who would carry out his orders to the letter. I added much about future favours, in the form of a message from the Duke. Upon this he looked me hard in the face, and said with a sarcastic smile: 'And you! to what extent are you satisfied with him?' Although I replied that I was extremely contented and was very well treated by his Excellency, he showed that he was acquainted with the greater part of my annoyances, and gave as his final answer that it would be difficult for him to leave Rome. To this I added that he could not do better than to return to his own land, which was governed by a prince renowned for justice, and the greatest lover of the arts and sciences who ever saw the light of this world. As I have remarked above, he had with him a servant of his who came from Urbino, and had lived many years in his employment, rather as valet and housekeeper than anything else; this indeed was obvious, because he had acquired no skill in the arts. Consequently, while I was pressing Michel Agnolo with arguments he could not answer, he turned round sharply to Urbino, as though to ask him his opinion. The fellow began to bawl out in his rustic way: 'I will never leave my master Michel Agnolo's side till I shall have flayed him or he shall have flayed me.' These stupid words forced me to laugh, and without saying farewell, I lowered my shoulders and retired."

This was in 1552. The Duke was loth to take a refusal, and for the next eight years he continued to ply Michelangelo with invitations, writing letters by his own hand, employing his agents in Rome and Florence, and working through Vasari. The letters to Vasari during this period are full of the subject. Michelangelo remains firm in his intention to remain at Rome and not abandon S. Peter's. As years went on, infirmities increased, and the solicitations of the Duke became more and more irksome to the old man. His discomfort at last elicited what may be called a real cry of pain in a letter to his nephew:—

"As regards my condition, I am ill with all the troubles which are wont to afflict old men. The stone prevents me passing water. My loins and back are so stiff that I often cannot climb upstairs. What makes matters worse is that my mind is much worried with anxieties. If I leave the conveniences I have here for my health, I can hardly live three days. Yet I do not want to lose the favour of the Duke, nor should I like to fail in my work at S. Peter's, nor in my duty to myself. I pray God to help and counsel me; and if I were taken ill by some dangerous fever, I would send for you at once."

Meanwhile, in spite of his resistance to the Duke's wishes, Michelangelo did not lose the favour of the Medicean family. The delicacy of behaviour by means of which he contrived to preserve and strengthen it, is indeed one of the strongest evidences of his sincerity, sagacity, and prudence. The Cardinal Giovanni, son of Cosimo, travelled to Rome in March 1560, in order to be invested with the purple by the Pope's hands. On this occasion Vasari, who rode in the young prince's train, wrote despatches to Florence which contain some interesting passages about Buonarroti. In one of them (March 29) he says: "My friend Michelangelo is so old that I do not hope to obtain much from him." Beside the reiterated overtures regarding a return to Florence, the Church of the Florentines was now in progress, and Cosimo also required Buonarroti's advice upon the decoration of the Great Hall in the Palazzo della Signoria. In a second letter (April 8) Vasari tells the Duke: "I reached Rome, and immediately after the most reverend and illustrious Medici had made his entrance and received the hat from our lord's hands, a ceremony which I wished to see with a view to the frescoes in the Palace, I went to visit my friend, the mighty Michelangelo. He had not expected me, and the tenderness of his reception was such as old men show when lost sons unexpectedly return to them. He fell upon my neck with a thousand kisses, weeping for joy. He was so glad to see me, and I him, that I have had no greater pleasure since I entered the service of your Excellency, albeit I enjoy so many through your kindness. We talked about the greatness and the wonders which our God in heaven has wrought for you, and he lamented that he could not serve you with his body, as he is ready to do with his talents at the least sign of your will. He also expressed his sorrow at being unable to wait upon the Cardinal, because he now can move about but little, and is grown so old that he gets small rest, and is so low in health I fear he will not last long, unless the goodness of God preserves him for the building of S. Peter's." After some further particulars, Vasari adds that he hopes "to spend Monday and Tuesday discussing the model of the Great Hall with Michelangelo, as well as the composition of the several frescoes. I have all that is necessary with me, and will do my utmost, while remaining in his company, to extract useful information and suggestions." We know from Vasari's Life of Michelangelo that the plans for decorating the Palace were settled to his own and the Duke's satisfaction during these colloquies at Rome.
