The chapel at Vincennes, with the Saint Chapelle of the Palais de Justice at Paris, ranks as one of the most exquisite examples extant of French Gothic architecture. It was begun in 1379, but chiefly it is of the sixteenth century, since it was only completed in 1552. This chapel of the sixteenth century, and the two side wings flanking the tower of the reign of Louis XIV, make the Chateau de Vincennes a most precious specimen of mediaeval ecclesiastical and military architecture. If Napoleon had not cut down the height of the surrounding walls the comparison would be still more favourable. In the reproduction of the miniature from the Book of Hours of the Duc de Berry given herein one sees the perfect outlines of the fourteenth century edifice. In later years, Louis XIII added considerably to the existing structure, but little is now to be seen of that edifice save the great tower and the chapel. Charles IX, whose royal edict brought forth the bloody night of Saint Bartholomew in 1572, fell sick two years later in the Chateau de Vincennes. Calling his surgeon, Ambroise Pare, to his side he exclaimed: "My body burns with fever; I see the mangled Huguenots all about me; Holy Virgin, how they mock me; I wish, Pare, I had spared them." And thus he died, abhorring the mother who had counselled him to commit this horrible deed. The donjon of Vincennes was carried to its comparatively great height that it might serve as a tower of observation as well as a place of last retreat if in an attack the outer walls of the fortress should give way. Here at Vincennes a certain massiveness is noted in connection with the donjon, though the actual ground area which it covers is not very great; it was not like many donjons of the time, which were virtually smaller chateaux or fortresses enclosed within a greater. Vincennes, in comparison with many other contemporary edifices, possessed a certain regularity of outline which was made possible by its favourable situation. When others were of fantastic form, they were usually so built because of the configuration of the land, or the nature of the soil. But here the land was flat, and, though the edifice and its dependencies covered no very extended area, they followed rectangular lines with absolute precision. As its walls were of a thickness of three metres, it was a work easy of accomplishment for Louis XI to turn the chateau into a Prison of State, a use to which the first chateau had actually been put by the shutting up in it of Enguerrand de Marigny. Henri IV, in 1574, passed some solitary hours and days within its walls, and Mirabeau did the same in 1777. The Duc d'Enghien, under the First Empire, before his actual death by shooting, suffered sorely herein, while resting under an unjust suspicion. [Illustration: _Chateau de Vincennes_]
