Jacopo da Pontormo having left unfinished at his death the chapel in S. Lorenzo, and the Lord Duke having ordained that Bronzino should complete it, he finished in the part where the Deluge is many nudes that were wanting at the foot, and gave perfection to that part, and in the other, where at the foot of the Resurrection of the Dead many figures were wanting over a space about one braccio in height and as wide as the whole wall, he painted them all in the manner wherein they are to be seen, very beautiful; and between the windows, at the foot, in a space that remained there unpainted, he depicted a nude S. Laurence upon a gridiron, with some little Angels about him. In that whole work he demonstrated that he had executed his paintings in that place with much better judgment than his master Pontormo had shown in his pictures in the work; the portrait of which Pontormo Bronzino painted with his own hand in a corner of that chapel, on the right hand of the S. Laurence. The Duke then gave orders to Bronzino that he should execute two large altar-pictures, one containing a Deposition of Christ from the Cross with a good number of figures, for sending to Porto Ferraio in the Island of Elba, for the Convent of the Frati Zoccolanti, built by his Excellency in the city of Cosmopolis; and another altar-piece, in which Bronzino painted the Nativity of Our Lord Jesus Christ, for the new Church of the Knights of S. Stephen, which has since been built in Pisa, together with their Palace and Hospital, after the designs and directions of Giorgio Vasari. Both these pictures have been finished with such art, diligence, design, invention, and supreme loveliness of colouring, that it would not be possible to go further; and no less, indeed, was required in a church erected by so great a Prince, who has founded and endowed that Order of Knights.
On some little panels made of sheet-tin, and all of one same size, the same Bronzino has painted all the great men of the House of Medici, beginning with Giovanni di Bicci and the elder Cosimo down to the Queen of France, in that line, and in the other from Lorenzo, the brother of the elder Cosimo, down to Duke Cosimo and his children; all which portraits are set in order behind the door of a little study that Vasari has caused to be made in the apartment of new rooms in the Ducal Palace, wherein is a great number of antique statues of marble and bronzes and little modern pictures, the rarest miniatures, and an infinity of medals in gold, silver, and bronze, arranged in very beautiful order. These portraits of the illustrious men of the House of Medici are all natural and vivacious, and most faithful likenesses.
