Cast Court, South Kensington Museum

Two architectural courts were designed by General Henry Scott in 1870 for the museum to house both cast reproductions of architectural elements, as well as some original pieces. The space opened in 1873. Salviati and Company made two mosaic reproductions that originally hung on the walls of the south-east Court.

The Good Shepherd is a copy of the lunette above the entrance of the Chapel of Galla Placida in Ravenna Italy originally from the 5th century.

The mosaic Figure of Christ is a copy from St. Mark's Basilica in Venice from the 13th century. It depicts the Savior giving a benediction (item 8036-1862), acquired by the museum in 1862 for 200BP, but which is now in storage. Salviati made another copy of a St. Mark's mosaic image of Christ for St. Augustine's College in Canterbury.

The museum also bought in 1864 a mosaic medallion of the head of St. John the Evangelist (item 797-1864) from Salviati for 25BP, but it is now also in storage.
