=The Treasury=, once endowed with enormous riches, was despoiled at the Revolution of all but a few objects of value. There still remains the reputed Crown of Thorns (supposed to have been given to St. Louis), brought hither from La Sainte Chapelle. The so-called Nail of the True Cross formerly belonged to the royal abbey of St. Denis. These relics are only exposed on Fridays in Lent. The reliquaries are for the most part imitations of those which were formerly in La Sainte Chapelle. Perhaps the most interesting of the objects exhibited is a gold cross, probably of twelfth-century workmanship. It belonged to the Emperor Manuel Comnenus, and was bequeathed by the Princess Anne de Gonzague to the church of St. Germain des Prés in 1863. In addition there are the relic of the True Cross sent to Bishop Galon in 1109, from the Church of the Holy Sepulchre in Jerusalem; the “discipline” of St. Louis; the crozier in copper and wood of Bishop Eudes de Sully; the crucifix used by St. Vincent-de-Paul at the death-bed of Louis XIII.; the pastoral cross of Archbishop Affre; a silver image of the Virgin and Child presented in 1821 by Charles X.; the _ostensoir_ given by Napoleon I., and services of plate presented by the same monarch and by Napoleon III. The vestments are very magnificent, and include the coronation mantle of Napoleon I. and the chasuble worn by Pope Pius VI. when he crowned him. The _soutanes_ worn by Archbishops Affre, Sibour, and Darboy in their last moments, marked by the instruments which produced their violent deaths, have a tragic interest. The somewhat obtrusively picturesque modern building to the west of the Sacristy is known as the _Presbytère_. It has been often ridiculed, and at times rather fiercely denounced, but if any building was to be erected on the site, it seems difficult to imagine anything less offensive. It is pleasing and unpretentious, and contrasts only too favourably with the dull houses of the Rue du Cloître Notre-Dame, which are as undistinguished as they well can be. The space at the back of the Cathedral is laid out as a garden. This is modern and somewhat formal, but it affords a fine view of the east end, and constitutes a welcome oasis of trees and grass in a grey waste of commonplace buildings. In the centre is a fountain with a statue of the Virgin and Child, and fragments of sculpture and carving taken from the church at different times lie about. The reader who wishes to understand at a glance the various changes which have taken place in that part of the French metropolis which lies in the very shadow of the cathedral should refer to the second volume of the magnificent work _Paris à travers les Ages_, in which a plan of the district in 1881 is compared with conjectural plans of the same in the years 1150, 1550, and 1750.
