This man found so much pleasure in cogitating and discoursing, that he would spend whole days without working; and when he did force himself to work, it was evident that he was suffering greatly in his mind, which was the chief reason that he was of the opinion that no price was large enough to pay for his works. For Cardinal Rangoni he painted a picture of a nude and very beautiful S. Agatha being tortured in the breasts, which was an exquisite work, and this picture is now in the guardaroba of Signor Guidobaldo, Duke of Urbino, and is in no way inferior to the many other most beautiful pictures that are there, by the hands of Raffaello da Urbino, Tiziano, and others. He also made a portrait from life of Signor Piero Gonzaga, painted in oils on stone, which was a very fine work; but he toiled for three years over finishing it. Now, when Michelagnolo was in Florence in the time of Pope Clement, engaged in the work of the new Sacristy of S. Lorenzo, Giuliano Bugiardini wished to paint for Baccio Valori a picture with the head of Pope Clement and that of Baccio himself, and another for Messer Ottaviano de' Medici of the same Pontiff and the Archbishop of Capua. Michelagnolo therefore sent to Sebastiano to ask him to despatch from Rome a head of the Pope painted in oils with his own hand; and Sebastiano painted one, which proved to be very beautiful, and sent it to him. After Giuliano had made use of the head and had finished his pictures, Michelagnolo, who was a close companion of the said Messer Ottaviano, made him a present of it; and of a truth, among the many heads that Fra Sebastiano executed, this is the most beautiful of all and the best likeness, as may be seen in the house of the heirs of Messer Ottaviano. The same master also took the portrait of Pope Paul Farnese, as soon as he was elected Supreme Pontiff; and he began one of the Duke of Castro, his son, but left it unfinished, as he did with many other works with which he had made a beginning.
