Not to mention the Renaissance mosaics of S. Mark's at Venice, the cupola of S. Maria del Popolo at Rome, executed in mosaic by Raphael, deserves special mention. A work illustrative of this cupola is one of Ludwig Grüner's best publications.
South Italy and Florence are distinguished by two marked styles in this decoration of inlaid marbles or opera di commesso. Compare the Medicean chapel in S. Lorenzo, for instance, with the high altar of the cathedral of Messina.
The roof of the Duomo at Volterra is a fine specimen.
