Testament and New Testament scenes that represented men and women equally. The mosaic project began in 1900, took five years to complete, and cost US$97,000. The "shimmering quality" of the mosaics, which resemble tapestry, were created by different tones of green and gold; the artists that installed them had over 20,000 shades of colors to choose from. Paoletti's watercolors were divided into two-foot-square sections, which were made into glass by other artists in Venice. The mosaics were then shipped in pieces by boat to New York and then by railroad to California, where they were placed on the church's walls. Artisan Lorenzo Zampato was given the task of supervising the in-studio fabrication and final installation at Stanford, which took 4 years to complete. The mosaic adorning the church's chancel is a reproduction of Rosselli's fresco of the Last Supper from the Sistine Chapel in the Vatican. Camerino obtained permission from Pope Leo XIII to reproduce it at Stanford Memorial Church. Unlike other works, which were reproduced frequently, it was the only reproduction of Rosselli's fresco at the time. There are 12 mosaics in each transept balcony that are split into two sets of six, creating an arc of six mosaics, ten windows, and six mosaics. Most of the church's mosaics were made from 1/8-inch tiles; larger 3/4-inch tiles were used on the higher mosaics, and smaller 1/4-inch tiles were used in "The Last Supper" mosaic. Organs Stanford Memorial Church houses five organs, a "situation only a few places in the nation can boast". The presence of high-quality organs makes Stanford an ideal location for accomplished musicians, and the sanctuary one of California's best settings for instrumental and choral performance. The church's organist is Robert Huw Morgan. Stanford Memorial Church's first organ, the 1901 Murray Harris, named for its builder Murray M. Harris, sits in the upstairs gallery and is still in use. Damaged in the 1906 earthquake, the organ was rebuilt in 1925, enlarged in 1933, and thoroughly restored in 1996. It features three manuals (keyboards for the hands), 57 stops, and over 3,700 pipes. The Murray Harris plays music from the Romantic period; its sound has been described as "romantic [and] undulating" and "like a low-decibel airplane engine revving up" Morgan compares the Murray Harris to both a Rolls-Royce and a Bentley. The Fisk-Nanney organ, which many consider one of the best organs in the world, was built in
