Anotations

Scope note:

Distinctive type of opus sectile ("cut work") technique, by which small triangles and rectangles of colored stones and glass mosaics are set into stone matrices or encrusted upon stone surfaces of floors, walls, or church fixtures; particularly as used in works with geometric patterns produced in Rome from the 12th to the 14th centuries. The name derives from the surname of a family of marbleworkers active in Rome, although all works of this type were not made by this one family.
