This study follows the stylistic evolution of Bartolo di Fredi, who studied with Niccolo di Ser Sozzo, and was influenced by the giants of the early Trecento: Martini, da Siena, and Pietro and Ambrogio Lorenzetti. Bartolo mined his rich Sienese artistic heritage for its most valuable characteristics, which he transformed into his own unique and appealing style.

The first extended study of the painting of Florence and Siena in the later 14th century, this book presents a rich interweaving of considerations of connoisseurship, style, iconography, cultural and social background, and historical events.

A comparison of Sassetta and Giotto as painters of the Franciscan legend. Originally published in 'Burlington Magazine', vol. 3, 1903.
