Having said above, in the Life of Perino del Vaga, that the painter Marcello Mantovano worked many years under him at pictures that gave him a great name, I have to say in this place, coming more to particulars, that he once painted in the Church of S. Spirito the whole Chapel of S. Giovanni Evangelista and its altar-piece, with the portrait of a Knight Commander of the same S. Spirito, who built that church and constructed that chapel; which portrait is a very good likeness, and the altar-piece most beautiful. Whereupon a Friar of the Piombo, having seen his beautiful manner, caused him to paint in fresco in the Pace, over the door that leads from the church into the convent, Jesus Christ as a boy disputing with the Doctors in the Temple, which is a very lovely work. But since he has always delighted to make portraits and little things, abandoning larger works, he has executed an infinite number of these; and among them may be seen some of Pope Paul III, which are beautiful and speaking likenesses. In like manner, from the designs of Michelagnolo and from his works he has executed a vast number of things likewise small, and among these he has depicted in one of his works the whole façade of the Judgment, which is a rare thing and executed excellently well; and in truth, for small paintings, it would not be possible to do better. For which reason, finally, that most gentle Messer Tommaso de' Cavalieri, who has always favoured him, has caused him to paint after the design of Michelagnolo an altar-picture of the Annunciation of the Virgin, most beautiful, for the Church of S. Giovanni Laterano; which design by Buonarroti's own hand, imitated by this Marcello, Leonardo Buonarroti, the nephew of Michelagnolo, presented to the Lord Duke Cosimo together with some others of fortifications and architecture and other things of the rarest. And this must suffice for Marcello, who has been attending lately to working at little things, executing them with a truly supreme and incredible patience.
