One of the most
fascinating personalities in Sienese painting, his figure has emerged out of a revision of the catalogue of works that had long been attributed to \b \cf4 \ATXht1034 Sassetta\b0 \cf0 \ATXht0 . Often showing close parallels with the activity of \b \cf4 \ATXht1043 Sano di Pietro\b0 \cf0 \ATXht0 , his painting is characterized by a continuous investigation of SassettaÆs legacy, accompanied by a significant modernization under the influence of the new use of color and perspective by Florentine painters (espec
ially \b \cf4 \ATXht1097 Fra Angelico\b0 \cf0 \ATXht0 , Domenico Veneziano and Paolo Uccello).
