In 1684 Mansart was entrusted with the entire transformation of the interior of the Petit Château; the first floor being arranged for the use of the Grand Condé, whilst the ground floor was reserved for his son, the Duc d'Enghien. The exterior of this exquisite building was fortunately left intact, and has remained unchanged since the time of Anne de Montmorency. Nor has the interior changed since Mansart's alterations. When the visitor passes through these apartments to-day, he can feel that they are in the same state as when the Grand Condé dwelt there. The Grand Cabinet with its exquisite Beauvais tapestry, its Boulle table, and its Louis XVI consoles and lustres, and the Petit Cabinet where the victor of Rocroy came to rest from his labours, still exist, to recall their former owner. In an adjacent apartment we may admire a fine piece of furniture, companion to the famous Louis XV bureau in the Louvre, upon which is placed the Grand Condé's own despatch-box. Then there is the Long Gallery, where the painter Sauveur Lecomte has illustrated, under the hero's own directions, all his victories from the battles of Rocroy, Nördlingen, and Fribourg to the conquest of the Franche Comté, and the campaign and passage of the Rhine. Mansart, once installed at Chantilly, did not leave it for many years. He unfortunately attempted to tamper with the old feudal castle of the Orgemonts and the mediæval architecture which combined so well with Montmorency's Petit Château, creating an inordinately lofty building, with a straight line of innumerable windows and attics all precisely similar in form. It was this structure which was razed to the ground at the time of the Revolution, and which was reconstructed in a far more suitable style by the late Duc d'Aumale. CHAPTER VI FESTIVITIES AT CHANTILLY Since there was no prospect for Condé to take any prominent lead in the affairs of his own country his name was proposed as a possible successor to the throne of Poland. He declined, however, to accept a crown which had been the cause of so much misery to King Wladislav IV and to his brother Jean Casimir. There being no heir-apparent to that throne the eyes of Marie de Gonzague, Queen of Poland, turned upon the Duc d'Enghien, Condé's only surviving son, and it was in connection with this idea that a marriage was arranged between Henri Jules de Bourbon and Anne of Bavaria, eldest daughter of the Princess Palatine, sister to the Polish Queen. Claire-Clemence was not over-pleased at the idea of this marriage, since she did not share her husband's ambitions. The uneasy throne of Poland for her only son was a proposal which she could not face with equanimity.
