The bas-relief is one of the famous works in enamelled terra-cotta, known as "Della Robbia ware." The idea of overlaying clay with a glazing was not original with Luca della Robbia, but he seems to have been the first to apply it to sculpture. In his own day he was looked upon as a great inventor, and his works were very popular. The material was inexpensive, and lent itself readily to all sorts of decorative purposes. Its beauty, moreover, was of a lasting quality. While paintings fade, the Della Robbia ware, "gem like, shall as very gems endure."[32] The only injury to which it is liable is the breaking off of some projecting portions. In our picture we see that a fragment is broken out of the child's wrist. Fortunately, however, there are no defects in the important parts of the work. The figures are in the centre of a lunette or semi-circular composition, with an adoring angel on each side holding a jar of lilies. The piece is set up over a doorway on the outside of a building in a narrow street in Florence. The location explains the attitude of the mother and child. If they looked directly out of the picture as in an altar-piece, there would be but one place, on the opposite side of the street, where the passer-by could meet their eyes. As it is, they turn their faces toward the vista of the street as if to welcome the approaching wayfarer. While still a long way off one feels the cheerful influence of their gaze. Even when coming from the opposite direction it is pleasant, after passing the door, to know that the friendly eyes follow us on our way. The workmanship of Luca is seen in the artistic qualities of the sculpture. There was a severe simplicity in his drawing of the outline and draperies which contrasted with the more elaborate work of his followers. Luca was also a close student of nature, and drew his materials from the world about him.

DOMINICK BY ANDREA DELLA ROBBIA In the beginning of the thirteenth century two men living in different countries of Europe were struck simultaneously with the same idea. They were St. Dominick, the Spaniard, and St. Francis, the Italian, and each determined to found a new religious order.[33] Hitherto the members of religious orders had shut themselves up in the solitude of monasteries and convents. In the new plan they were to mingle freely with the people, calling themselves brothers, or friars.
