(b. ca. 1420, Firenze, d. 1497, Pistoia)
St Augustine Teaching in Rome (detail)1464-65
Apsidal chapel, Sant'Agostino, San Gimignano
St Augustine is depicted as a scholar of rhetoric in a perspectively constructed interior. On either side listeners are arranged almost as mirror images. The parallel lines of the floor tiles converge on the face of the saint, thus drawing one's attention to him. In the foreground a little dog is sitting, who was considered by Fathers of the Church to be a guard and loyal shepherd, and was interpreted as a symbol of the preacher.
