Arguably the one of the most important existing works in marble by Luca (executed in 1454–1456) is the tomb of Benozzo Federighi, bishop of Fiesole, originally placed in the church of San Pancrazio, Florence, but removed to San Francesco di Paola on the Bellosguardo road outside the city in 1783. In 1898 it was again removed to the church of Santa Trinita in Florence. An effigy of the bishop in a restful pose lies on a sarcophagus sculptured with graceful reliefs of angels holding a wreath which contains the inscription. Above are three-quarter length figures of Christ between St John and the Virgin, of conventional type. The whole is surrounded by a rectangular frame formed of painted tiles. On each tile is painted, with enamel pigments, a bunch of flowers and fruit in brilliant realistic colors. Though the bunch of flowers on each is painted on one slab, the ground of each tile is formed of separate pieces, likely because the pigment of the ground required a different degree of heat in firing from that needed for the enamel painting of the center.
