St. Peter's Church Colton

Built 1873-74 by architectural firm Paley and Austin, the design of the church is a "mountain chapel" style.

The mosaic reredos by Salviati are from 1883. They depict the four Evangelists in their symbolic forms - angel, lion, bull and eagle - surrounding the Lamb of God on a cross with two angels.

Exeter College Chapel

Located in the heart of Oxford, the Chapel of Exeter College was built 1856-59 by G.G. Scott and modeled after Paris' Sainte Chapelle. The "greater part of the mosaics" on the east end were the gift of Dr. George Ridding, Bishop of Southwell.

The arcaded Salviati mosaics in the apse feature familiar themes for such locations: the four Evangelists, Christ and angels, the Lamb of God and the Pelican in her Piety. An 1871 catalog called "Views of Oxford" already refers to a "mosaic altarpiece" and based upon a photograph located in the Cornell University archives, by 1885 they had all been installed.

St. Paul's Cathedral

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.
