Michelagnolo was employed in the time of Pope Paul IV on many parts of the fortifications of Rome, and also by Salustio Peruzzi, to whom that Pope, as has been related elsewhere, had given the charge of executing the great portal of the Castello di S. Angelo, which is now half ruined; and he occupied himself in distributing the statues of that work, examining the models of the sculptors, and correcting them. At that time the French army approached near to Rome, and Michelagnolo thought that he was like to come to an evil end together with that city; whereupon he resolved to fly from Rome with Antonio Franzese of Castel Durante, whom Urbino at his death had left in his house as his servant, and went secretly to the mountains of Spoleto, where he visited certain seats of hermits. Meanwhile Vasari wrote to him, sending him a little work that Carlo Lenzoni, a citizen of Florence, had left at his death to Messer Cosimo Bartoli, who was to have it printed and dedicated to Michelagnolo; which, when it was finished, Vasari sent in those days to Michelagnolo, and he, having received it, answered thus: "_September_ 18, 1556. "MESSER GIORGIO, DEAR FRIEND, "I have received Messer Cosimo's little book, which you send to me, and this shall be a letter of thanks. I pray you to give them to him, and send him my compliments. "I have had in these days great discomfort and expense, but also great pleasure, in visiting the hermits in the mountains of Spoleto, insomuch that less than half of me has returned to Rome, seeing that in truth there is no peace to be found save in the woods. I have nothing more to tell you. I am glad that you are well and happy, and I commend myself to you."
