In the same place this same master did a very fine Transfiguration in fresco on a cupboard in the chapel. Being much inclined by nature to the study of herbs, he devoted himself to the mastery of Dioscorides, taking pleasure in learning the properties and virtues of each plant, so that he ultimately abandoned painting and devoted himself to distilling simples with great assiduity. Having thus transformed himself from a painter into a physician, he pursued the latter profession for some time. At length he fell-sick of a disorder of the stomach, or, as some say, through treating the plague, and finished the course of his life at the age of seventy-four in the year 1384, when the plague was raging in Florence. His skill as a physician equalled his diligence as a painter, for he gained an extensive experience in medicine from those who had employed him in their need, and he left behind him a high reputation in both arts. Antonio was a very graceful designer with the pen, and so excellent in chiaroscuro that some sheets of his in our book, in which he did the arch of S. Spirito, are the best of the age. Gherardo Starnini of Florence was a pupil of Antonio, and closely imitated him, while another pupil of his, Paolo Uccello, brought him no small credit. The portrait of Antonio of Venice by his own hand is in the Campo Santo at Pisa. Jacopo di Casentino, Painter. As the fame and renown of the paintings of Giotto and his pupils had been spread abroad for many years, many, who were desirous of obtaining fame and riches by means of the art of painting, began to be animated by the hope of glory, and by natural inclination, to make progress towards the improvement of the art, feeling confident that, with effort, they would be able to surpass in excellence Giotto, Taddeo, and the other painters. Among these was one Jacopo di Casentino, who was born, as we read, of the family of M. Cristoforo Landino of Pratovecchio, and was associated by the friar of Casentino, then superior at the Sasso del Vernia, with Taddeo Gaddi, while he was working in that convent, in order that he might learn design and colour. In a few years he so far succeeded, that, being taken to Florence in the company of Giovanni di Milano, in the service of their master, Taddeo, where they were doing many things, he was asked to paint in tempera the tabernacle of the Madonna of the Old Market, with the picture there, and also the one on the Via del Cocomoro side of the Piazza S. Niccolo. A few years ago both of these were restored by a very inferior master to Jacopo. For the Dyers, he did the one at S. Nofri, on the side of their garden wall, opposite S. Giuseppe. While the vaulting of Orsanmichele, upon its twelve pillars, was being completed, and covered with a low, rough roof, awaiting the completion of the building of the palace, which was to be the granary of the Commune, the painting of these vaults was entrusted to Jacopo di Casentino, as a very skilled artist. Here he
