The windows of the 16th century most fully display the influence of the Renaissance, with greater realism and closer resemblance to paintings. A good example is the window in the Chapel of Saint-Joseph, in the south transept. While it is full of activity and detail, it lacks some of the depth and richness of color given by the thick, densely-coloured glass of the 13th-century windows. Other major 16th-century works are two windows of the Saint-Romain chapel, the south part of the nave next to the transept. These are based on the work of the Rouen painter Arnoult de Nimegue or his followers. They depict scenes from the life of the archbishop Romaine, best known in Rouen legends for ridding the city of a monster called "The Gargoyle". Modern windows (20th century) The Cathedral has a number of modern windows created in the 1950s to replace windows which were destroyed in the bombardments of the Second World War. They resemble, in their colors and the density of their imagery, the earlier medieval and Renaissance windows. One example is found in the Chapel of St. Leonard, Bay 50. Other striking examples are the three Joan of Arc windows in the Chapel of Joan-of-Arc in the South transept, bays 22, 24 and 26. These were made in 1955–56. Bells The cathedral has seventy bells made by the Fonderie Paccard in Annecy. There are sixty-four in the Saint-Romain Tower and six in the Butter Tower. Together they are the heaviest "peal" or group of bells in France, with a combined weight of thirty-six tons. Grand Organ The cathedral had an organ since the 1380s. A larger new organ was constructed beginning in 1488, and placed at the beginning of the nave, on the inside of the west front under the rose window. This organ was damaged in the hurricane of 1683, but was put back into service. Prominent organists included Jean Titelouze from 1588 until 1634, and Jacques Boyvin from 1674 until 1706. A smaller organ had been installed in the choir in 1517, in the center of the Choir screen, removed during the Renaissance. New organs were built by Merklin & Schütze (1858–60) and, after World War II, by Jacquot-Lavergne. Treasury The treasury of the Cathedral was originally in the Sacristy, and then was moved to its own tower on the Alban Courtyard, on the north side of the cathedral. It was twice
