of styles and motifs reflecting the hands of different craftsmen. The mosaic that adorns the floor depicts the Lamb of God surrounded by the symbols of the four gospel writers: St. Matthew (the winged angel), St. Mark (the winged lion), St. Luke (the ox), and St. John (the eagle). Some of these symbols also appear in other areas of the church. A Celtic cross adorns the stained glass above the central wooden door that leads into the nave, and Latin epigraphs have been engraved above the two side doors. Above the narthex is an organ gallery. The nave is arcaded and has a single aisle on each side with clerestory windows above. Its walls, from the floor to the top of the clerestory, are decorated with 15 murals made of mosaics on each side, and depicts scenes from the Old Testament. The exposed timber ceiling was inspired by Trinity Church and is constructed with tied hammer beams, which can be seen radiating in the chancel. The floor of the church slopes downward towards the crossing. The chancel and transepts are three semi-circular apses. They are separated from the broad central space by large semi-circular arches on stout columns with carved capitals. The transept apses each have a balcony with a concave balustrade. Directly above the crossing is a dome supported on pendentives. Around the base of the dome are decorative gilt bands, the lower depicting a scrolling vine. Jane Stanford intended the dome's decoration of to be of mosaic tiles showing a variety of symbols, but the church's builders thought it would make the dome too heavy, so the decorations were painted. On the spandrels of the pendentives are mosaics of four angels measuring from wing tip to wing tip, rising from clouds. The angels survived the 1906 earthquake, but the angel looking downward was severely damaged during the 1989 earthquake because an 8-foot section of its left wing fell . The chancel, according to Hall, contains "artistic work of a kind seldom seen anywhere". The raised tiled floor of the chancel curves outward into the body of the church, and is approached by seven marble steps. The sanctuary is raised further, and enclosed by a marble altar rail behind which is an altar carved from white Carrara marble by L.M. Avenali. The altar supports a "simple unadorned brass cross that reflects the colors of the mosaics surrounding it." The
