Adjoining the choir on the right is a sacristy occupying a small structure, and to the westward is a fragmentary edifice known as the _Basse OEuvre_,--one of the oldest existing buildings in France; a Romano-Byzantine work, variously stated as of the sixth to eighth century and forming a portion of the original church which occupied the site of the present Cathedral. The general impressiveness of this great church--the memory which most of us will carry away--is caused by its immensity, its loftiness, and the general effect of lightness. These form an irresistible galaxy of features which can hardly fail to produce a new and startling sensation upon any observer. As to decorative embellishments, the church is by no means lacking. The coloured glass, typical of the best period of the art, is luxurious and extensive; that contained in the north and south transept rose windows being the exceedingly beautiful work of Le Prince, a celebrated sixteenth-century artist. Numerous side chapels surround the ambulatory of the choir, and on the west wall of the transept are hung the eight tapestries after the sixteenth-century Raphael cartoons now at South Kensington. These tapestries are, it is to be presumed, late copies, since, of the two early sets woven at Arras, one is preserved in the Vatican and the other at the Museum at Berlin. A modern fresco of Jeanne Hachette, a local Amazon, adorns one of the choir chapels. A modern astronomical clock, with numerous dials, striking figures, and crowing cocks, is placed near the north transept. It might naturally be supposed that in our day the canons of good taste would plead against such a mere "curio" being housed in a noble church. The former Bishop's Palace, dating from the fourteenth to sixteenth centuries, is now the Palace of Justice. The present episcopal residence is immediately to the north of the Cathedral and is modern. As a tapestry-making centre Beauvais ranks with the famous Gobelin Manufactory at Paris.
