Michelagnolo had been seventeen years in the fabric of S. Pietro, and several times the deputies had tried to remove him from that position, but they had not succeeded, and they were seeking to oppose him in every matter now with one vexatious pretext and now with another, hoping that out of weariness, being now so old that he could do no more, he would retire before them. It happened in those days that Cesare da Castel Durante, who had been the overseer, died, and Michelagnolo, to the end that the fabric might not suffer, sent there Luigi Gaeta, who was too young but very competent, until he should find a man after his desire. The deputies (some of whom had many times made efforts to place there Nanni di Baccio Bigio, who was always urging them and promising great things), in order to be able to disturb the affairs of the fabric at their pleasure, sent Luigi Gaeta away, which having heard, Michelagnolo, as in anger, would no longer show himself at the fabric; whereupon they began to give out that he could do no more, that it was necessary to give him a substitute, and that he himself had said that he did not wish to be embroiled any longer with S. Pietro. All this came to the ears of Michelagnolo, who sent Daniello Ricciarelli of Volterra to Bishop Ferratino, one of the superintendents, who had said to the Cardinal of Carpi that Michelagnolo had told one of his servants that he did not wish to be mixed up with the fabric any longer; and Daniello said that this was by no means Michelagnolo's desire. Ferratino complained that Michelagnolo would not make his conception known, adding that it would be well for him to provide a substitute, and that he would have gladly accepted Daniello; and with this Michelagnolo appeared to be content. Thereupon Ferratino, having had the deputies informed in the name of Michelagnolo that they now had a substitute, presented not Daniello, but in his place Nanni di Baccio Bigio, who came in and was accepted by the superintendents. Before very long he gave orders to make a scaffolding of wood from the side of the Pope's stables, where the hill is, to rise above the great recess that is turned towards that side, and caused some stout beams of fir to be cut, saying that too many ropes were consumed in drawing up the materials, and that it was better to raise them by his method. Which having heard, Michelagnolo went straight to the Pope, who was on the Piazza di Campidoglio, and made so much noise that his Holiness made him go at once into a room, where he said: "Holy Father, there has been appointed as my substitute by the deputies a man of whom I know nothing; but if they are convinced, and also your Holiness, that I am no longer the proper man, I will return to rest in Florence, where I will enjoy the favours of that great Duke who has so long desired me, and will finish my life in my own house; I therefore beg your gracious leave." The Pope was vexed
