St. Mary's, Riverhead

This 1831 church was extended by Arthur W. Blomfield in 1882.
 

The central panel of the triparte reredos depicts Christ in Majesty in mosaic by Salviati from 1894.

The opus sectile mosaics on either side featuring groups of angels were made by the mosaic company of James Powell and Sons between 1910 and 1914. The sketches were made by Coakes and the cartoons by Hardgrave.

Bonn Minster

Also known as St. Martin's Cathedral, this is one of Germany's oldest churches, dating back to before the 13th century.

Salviati made a total of 800 square feet of mosaics for the portal and apse of the cathedral in 1894, modeled after cartoons by Professor Martin and Friz Geiges.
