Giorgio Vasari, Lives of the Most Excellent Painters… (1850)
“ THE PAINTER JACOPO DI CASENTINO. [Flourished in the middle of the fourteenth century.] The fame of Giotto, the renown attached to his works, and to those of his disciples, having for several years been much bruited abroad, many persons, desirous of acquiring honour and riches by the art of painting, and incited to study by nature and inclination, began to labour for the amelioration of the art, most of them being firmly persuaded that by their efforts the attainments of Giotto, Taddeo, and all the other painters, would be far surpassed. ”
