The Crypt, located beneath the Choir, is closed, pending work on other parts of the Cathedral. And on account of the consequent dampness, the delicate furnishings were removed in September, 1916, and entrusted to the care of Mr. Louis C. Tiffany, who designed them, and who has placed them temporarily in the private chapel on his large country estate at Laurelton, L. I. The Crypt has a seating capacity of 500, and the first services in the Cathedral were held in it from January 8, 1899, until the Choir and Crossing were opened on April 19, 1911. In its furnished state, it contains an Altar, Reredos, font, lectern, and five stained glass windows which were exhibited by Mr. Tiffany at the World’s Fair at Chicago in 1893 and which were called collectively the _Tiffany Chapel_. The top and retable of the _Altar_ are of Carrara marble, while the front and sides are adorned with medallions of mother of pearl, four smaller discs containing emblems of the four Evangelists, a central shield set with sapphires, topazes and mother of pearl, and 150,000 pieces of glass mosaic. The _Reredos_ is of iridescent glass mosaic, as are the twelve _Pillars_ back of the Altar symbolizing the twelve Apostles. The general effect is Byzantine. The Altar, Reredos, font, lectern and windows were given by Mrs. Celia Hermione Wallace in memory of her son. The following interments have been made in the Crypt: The Very Rev. William M. Grosvenor, D.D., Dean of the Cathedral, December 13, 1916; the Right Rev. David H. Greer, D.D., eighth Bishop of New York, May 23, 1919; and the Right Rev. Charles S. Burch, D.D., ninth Bishop of New York, December 23, 1920. Summary Dimensions Following are the principal dimensions of the Cathedral.
