St. Paul's Cathedral in central London, designed by Sir Christopher Wren and built between 1675-1710, contains several Salviati mosaics under its grand dome.
In 1862, the first two of eight decorated spandrels were commissioned.
Isaiah, designed by Alfred Stevens, was installed in 1864.
Matthew, based on a design by G.F. Watts, was installed in 1866.
The four Evangelists (from left to right): Matthew, Mark, Luke and John.
The designs for Jeremiah and John were also began by Watts, while those for Ezekiel and Daniel were by either Watts or Stevens. However, neither man was able to bring the work to completion, so they were finished by W.E.F. Britten, along with his own designs for Mark and Luke. They were manufactured in Venice in 1893.
The four Prophets: Isaiah, Jeremiah, Ezekiel and Daniel.
