Strange as it will appear to Englishmen, the Hôtel Cluny is not only open to the public on Sundays, but is open to the public on Sundays only. On other days permission to visit the museum must be obtained from the Minister of Fine Arts. Exceptions are made in favour of foreigners exhibiting their passports. CHAPTER XVI. THE MUSÉE D’ARTILLERIE. The Museum of Artillery--Its Origin and History--The Growth of its Collection of Armour and Weapons of all Kinds. The Museum of Artillery, with its varied and admirably classified collection of arms, takes us back to prehistoric times, and after exhibiting rude martial implements of dim antiquity, brings us forward through successive ages of arms until it at length produces the very piece which is to-day in the hands of the French soldier. The origin of the Musée d’Artillerie may be traced to the reign of Louis XIV. The Duc d’Humières, Grand Master of Artillery, obtained of the great monarch permission to place, in one of the halls of the royal magazine at the Bastille, a collection of small models of artillery then in use. This collection, intended to serve for the instruction of young artillery officers, was exhibited in glass cases. The Duc de Maine and the Comte d’Eu, who succeeded d’Humières, did nothing towards the development of this happy idea, which was only resumed on the abolition of the post of Grand Master in 1755 by Lieutenant-General de Vallières, who succeeded the count as First Inspector-General. A certain number of ancient arms and of new models were transported to the Academy, and an inventory of the collections, which is still extant, was prepared. In 1788 the celebrated General de Gribeauval, regarded by French writers as the creator of modern artillery, succeeded de Vallières as Inspector-General. It was by means of little models constructed beneath his eyes that Gribeauval had prosecuted his studies, and it was his familiarity with models which enabled him to determine the precise form of the arms to be employed in his new system. The idea of these little models extended itself to all the machines used in the artillery, as likewise to those ancient arms of which specimens had been preserved. Generalising his idea, Gribeauval determined to apply it to the creation of a complete establishment, and his project was in due time realised. The Minister of War, Comte de Brienne, at the reiterated recommendation of the general, granted to Rolland, Commissary of War and chief in the office of General Inspection of Artillery, a commission which named him director of the new museum. The programme proposed by Gribeauval embraced every description of war implements, whether past or present; nor did it exclude a collection of all the projects which had hitherto been proposed to the State by inventors.
