On the first of April, 1810, the Regent was called upon to add its glory to the gorgeous scene in the long gallery of the Louvre on the occasion of the official marriage of Napoleon with Marie Louise. The Emperor who was very fond of splendid pageants was attired in the most magnificent apparel contained in the imperial wardrobes. But he seldom had the stoical patience demanded of those who pose as kings. He never could acquire the deliberate stateliness of Louis XIV. who was born and brought up within the narrow limits of regal etiquette. Indeed the Emperor was frequently known to divest himself of his costly robes in a very expeditious manner going so far as actually to kick--unholy sacrilege!--the imperial mantle out of his way. On the day of his marriage with the Archduchess the Regent was used to decorate the cap of the bridegroom. Madame Durand, one of the ladies-in-waiting to the new Empress, has left an account of the ceremony in which occurs the following passage:-- "He (Napoleon) found his black velvet cap, adorned with eight rows of diamonds and three white plumes fastened by a knot with the Regent blazing in the centre of it, particularly troublesome. This splendid headgear was put on and taken off several times, and we tried many different ways of placing it before we succeeded." Like poor Louis XVI. at his coronation Napoleon found that his sparkling top-hamper hurt him. There was little opportunity for the Regent to appear fittingly after this event, although no doubt it was present at that kingly gathering in Dresden in the spring of 1812, when Napoleon in the plenitude of his power was starting upon the Russian campaign. But in the crash of a falling throne the imperial diamond is lost to view. When Marie Louise escaped from Paris in 1814, flying before the advancing allies she took with her all the crown jewels, and specie to the amount of four millions. These valuables the fugitive Empress kept with her until she reached Orleans, where she was overtaken by M. Dudon a messenger from the newly-returned Bourbon king. This gentleman demanded and obtained the restoration of the money and the jewels. Thus the Regent was forced to abandon the fallen dynasty and to return to Paris to embellish the cap of the new king.
