Returning to Florence, he gave some attention to the study of music; and, delighting much therein, he would sometimes sing to pass the time. At Prato, opposite to the prison, he painted a panel-picture of the Assumption. He executed some pictures of Our Lady for the house of the Medici, and also other paintings for various people, such as a picture of Our Lady which Lodovico di Lodovico Capponi has in his apartment, and likewise another of the Virgin holding the Child in her arms, with two heads of saints, that is in the possession of the very Excellent Messer Lelio Torelli, Chief Secretary to the most Illustrious Duke Cosimo, who holds it very dear both on account of the genius of Fra Bartolommeo, and because he delights in, loves, and favours not only the men of our art, but every fine intellect. In the house of Piero del Pugliese, which now belongs to Matteo Botti, a citizen and merchant of Florence, in an antechamber at the head of a staircase, he painted a S. George in armour, on horseback, who is slaying the Dragon with his lance--a very spirited figure. This he executed in chiaroscuro, in oils, a method that he much delighted to use for all his works, sketching them in the manner of a cartoon, with ink or with bitumen, before colouring them; as may still be seen from many beginnings of pictures and panels, which he left unfinished on account of his death, and as may also be perceived from many drawings by his hand, executed in chiaroscuro, of which the greater part are now in the Monastery of S. Caterina da Siena on the Piazza di S. Marco, in the possession of a nun who paints, and of whom record will be made in the proper place; while many made in the same way adorn our book of drawings, honouring his memory, and some are in the hands of Messer Francesco del Garbo, a most excellent physician. Fra Bartolommeo always liked to have living objects before him when he was working; and in order to be able to draw draperies, armour, and other suchlike things, he caused a life-size figure of wood to be made, which moved at the joints; and this he clothed with real draperies, from which he painted most beautiful things, being able to keep them in position as long as he pleased, until he had brought his work to perfection. This figure, worm-eaten and ruined as it is, is in our possession, treasured in memory of him.
