““The floor is a fifteenth-century revival of medieval Cosmatesque mosaic style. The Cosmati family developed their unmistakable technique in Rome in the twelfth and thirteenth centuries. This decorating style was a fantasy of geometric shapes and swirls in cut pieces of colored glass and marble (much of which was “recycled” from pagan Roman palaces and temples). Stunning examples of authentic Cosmati floors and decorations can be found in some of the oldest and most beautiful churches, basilicas, and cloisters in Rome and southern Italy.””
