In the Ricordi, which run from April 9 to August 19, 1521, he says that on April 9 he received two hundred ducats from the Cardinal de' Medici to go to Carrara and lodge there, to quarry marbles for the tombs which are to be placed in the new sacristy at San Lorenzo. "And there I stayed about twenty days and made out drawings to scale, and measured models in clay for the said tombs." On August 16 the contractors for the blocks, all of which were excavated from the old Roman quarry of Polvaccio, came to Florence, and were paid on account.

The statue of the "Risen Christ" was forwarded to Rome during the summer. The smaller detached, or more easily broken portions, were left in the rough to prevent accidents during the journey, and Pietro Urbino went to Rome with orders to complete the work there. Sebastiano del Piombo, like the good friend he was, kept Michael Angelo informed of the progress of the young scamp of a pupil, from whom his master had extracted a promise that he would avoid the company of dissolute Florentines in Rome more than he had previously done. On November 9, 1520, Sebastiano writes that his gossip, Giovanni da Reggio, "goes about saying that you have not done the figure yourself, but that it is the work of Pietro Urbino. Be sure that it may be seen to be from your hand, so that poltroons and babblers may burst." This was written whilst the work was still at Florence. On September 6, 1531, after it had arrived at Rome, Sebastiano says of Pietro: "Firstly, you sent him to Rome with the statue, to finish and erect it. What he did and did not do you know; but I must let you understand that wherever he has worked he has maimed it. Chiefly, he has shortened the [pg 188]right foot, and it is plainly seen that he has cut off the toes. He has shortened the fingers of the hands, too, more especially those of the one which holds the cross, the right; Frizzi says, it seems to have been worked by a cake-maker, not carved in marble. It looks as if it had been made by one who worked in dough, it is so stunted. I do not understand these things, not knowing the manner of working in marble; but I can very well tell you that those fingers look to me very stumpy. I can tell you, too, that it is easy to see he has been working on the beard. I believe a baby would have had more discretion; it looks as though he had done the hair with a knife without a point; but this can easily be remedied. He has also cut one of the nostrils, so that with a little more the whole nose would have been spoiled, so that no one but God could have mended it, and I believe God inspired you to write your last letter to Master Zovane da Reggio, my comrade, for if the figure had remained in the hands of Pietro he would undoubtedly have ruined it." Michael Angelo transferred the work of finishing from Pietro to Federigo Frizzi. Sebastiano goes on to say: "Pietro is most malignant now that he is cast off by you. He does not seem to value you or any one else alive, but thinks he is a great master; he will find out what he is fast enough, for I believe the poor young man will never know how to make statues. He has forgotten the art. The knees of your statue are worth more than all Rome."
