No such difficulties as we have encountered in the study of Uccello, Castagno, and Veneziano meet us as we turn to Fra Filippo. His works are still copious, and many of them are admirably preserved; we therefore have every facility for judging him as an artist, yet nothing is harder than to appreciate him at his due. If attractiveness, and attractiveness of the best kind, sufficed to make a great artist, then Filippo would be one of the greatest, greater perhaps than any other Florentine before Leonardo.
