“Nos. 7632-7643. Luca della Robbia. A series of twelve circular medallions, in enamelled terra-cotta, painted in _chiar’oscuro_, with impersonations of the twelve months. Diameter of each, 1 foot 10½ inches. Vasari tells us that ‘Luca sought to invent a method of painting figures and historical representations on flat surfaces of terra-cotta, which, being executed in vitrified enamels, would secure them an endless duration; of this he made an experiment on a medallion, which is above the tabernacle of the four saints on the exterior of Or San Michele, on the plane surface of which he delineated the instruments and emblems of the builder’s arts, accompanied with beautiful ornaments. For the bishop of Fiesole, in the church of San Brancazio, he also made a marble tomb on which are the recumbent effigy of the bishop and three other half-length figures besides, and in the pilasters of that work he _painted_, on the flat, certain festoons and clusters of fruit and foliage so skilfully and naturally, that, were they even _painted in oil on panel_, they could not be more beautifully or forcibly rendered.’ We have here a record of the fact that Luca, simultaneously with his enamelled terra-cotta sculptures, also practised _painting_ in the same vehicle on the flat, or, in other words, the art of majolica painting. The monumental works before mentioned are now extant to attest the truth of this account. “From a careful and repeated study of the above-named works on the spot, and likewise from the internal evidence of the technical qualities of the vehicle, terra-cotta, enamel pigments, &c., the writer has now to add to the list of Luca’s productions, in this especially interesting branch, the present series of medallions, doubtless united originally in a grand decorative work. Each roundel is a massive disc of terra-cotta, of a single piece, evidently prepared to be built into a wall (or vaulted ceiling) of some edifice. Round the margin of each is a decorated moulding, in relief, of a characteristic Della Robbia type. The surface within the narrow border is flat or plane, and the designs are painted in two or three grisaille tints on a blue ground, of the usual quiet sober tint affected in all the backgrounds and plane surfaces of the relievo subjects. These consist of single figures of _contadini_ or husbandmen, impersonating the agricultural operations of the Florentine country, characteristic of each month of the year; and although invested with a certain artistic charm of expression, the various figures, each of which exhibits a different individual character, may be taken as life portraits of the sturdy Tuscan peasants of the day. A band or _fascia_ forming an inner border round each subject, is ingeniously and fancifully divided into two unequal halves, one being of a lighter tint than the general ground of the composition, and the other half darker, thus indicating the night and the day; the
