In spite of Clement's orders that Michelangelo should confine himself strictly to working on the Medicean monuments, he continued to be solicited with various commissions. Thus the Cardinal Cybo wrote in December begging him to furnish a design for a tomb which he intended to erect. Whether Michelangelo consented is not known. Early in December Sebastiano resumed his communications on the subject of the tomb of Julius, saying that Michelangelo must not expect to satisfy the Duke without executing the work, in part at least, himself. "There is no one but yourself that harms you: I mean, your eminent fame and the greatness of your works. I do not say this to flatter you. Therefore, I am of opinion that, without some shadow of yourself, we shall never induce those parties to do what we want. It seems to me that you might easily make designs and models, and afterwards assign the completion to any master whom you choose. But the shadow of yourself there must be. If you take the matter in this way, it will be a trifle; you will do nothing, and seem to do all; but remember that the work must be carried out under your shadow." A series of despatches, forwarded between December 4, 1531, and April 29, 1532, by Giovan Maria della Porta to the Duke of Urbino, confirm the particulars furnished by the letters which Sebastiano still continued to write from Rome. At the end of 1531 Michelangelo expressed his anxiety to visit Rome, now that the negotiations with the Duke were nearly complete. Sebastiano, hearing this, replies: "You will effect more in half an hour than I can do in a whole year. I believe that you will arrange everything after two words with his Holiness; for our Lord is anxious to meet your wishes." He wanted to be present at the drawing up and signing of the contract. Clement, however, although he told Sebastiano that he should be glad to see him, hesitated to send the necessary permission, and it was not until the month of April 1532 that he set out. About the 6th, as appears from the indorsement of a letter received in his absence, he must have reached Rome. The new contract was not ready for signature before the 29th, and on that date Michelangelo left for Florence, having, as he says, been sent off by the Pope in a hurry on the very day appointed for its execution. In his absence it was duly signed and witnessed before Clement; the Cardinals Gonzaga and da Monte and the Lady Felice della Rovere attesting, while Giovan Maria della Porta and Girolamo Staccoli acted for the Duke of Urbino. When Michelangelo returned and saw the instrument, he found that several clauses prejudicial to his interests had been inserted by the notary. "I discovered more than 1000 ducats charged unjustly to my debit, also the house in which I live, and certain other hooks and crooks to ruin me. The Pope would certainly not have tolerated this knavery, as Fra Sebastiano can bear witness, since he wished me to complain to Clement and have the notary hanged.
