Exceptional depth also was necessary, as the stage arrangements were to be such as to admit a scene fifty feet high to be lowered on its frame.It was therefore necessary to lay a foundation in a soil soaked with water which should be sufficiently solid to sustain a weight of 22, pounds, and at the same time to be perfectly dry, as the cellars were intended for the storage of scenery and properties.While the work was in progress, the excavation was kept free from water by means of eight pumps, worked by steam power, and in operation, without interruption, day and night, from March second to October thirteenth.The floor of the cellar was covered with a layer of concrete, then with two coats of cement, another layer of concrete and a coat of bitumen.
The wall includes an outer wall built as a coffer-dam, a brick wall, a coat of cement, and a wall proper, a little over a yard thick.
After all this was done the whole was filled with water, in order that the fluid, by penetrating into the most minute interstices, might deposit a sediment which would close them more surely and perfectly than it would be possible to do by hand.Twelve years elapsed before the completion of the building, and during that time it was demonstrated that the precautions taken secured absolute impermeability and solidity.
"The events of 1870 interrupted work just as it was about to be prosecuted most vigorously, and the new Opera House was put to new and unexpected uses.During the siege, it was converted into a vast military storehouse and filled with a heterogeneous mass of goods.After the siege the building fell into the hands of the Commune and the roof was turned into a balloon station.
The damage done, however, was slight.
"The fine stone employed in the construction was brought from quarries in Sweden, Scotland, Italy, Algeria, Finland, Spain, Belgium and France.While work on the exterior was in progress, the building was covered in by a wooden shell, rendered transparent by thousands of small panes of glass.In 1867 a swarm of men, supplied with hammers and axes, stripped the house of its habit, and showed in all its splendor the great structure.No picture can do justice to the rich colors of the edifice or to the harmonious tone resulting from the skilful use of many diverse materials.
The effect of the frontage is completed by the cupola of the auditorium, topped with a cap of bronze sparingly adorned with gilding.
Farther on, on a level with the towers of Notre-Dame, is the gable end of the roof of the stage, a `Pegasus', by M.Lequesne, rising at either end of the roof, and a bronze group by M.Millet, representing `Apollo lifting his golden lyre', commanding the apex.
Apollo, it may here be mentioned, is useful as well as ornamental, for his lyre is tipped with a metal point which does duty as a lightning-rod, and conducts the fluid to the body and down the nether limbs of the god.
"The spectator, having climbed ten steps and left behind him a gateway, reaches a vestibule in which are statues of Lully, Rameau, Gluck, and Handel.Ten steps of green Swedish marble lead to a second vestibule for ticket-sellers.Visitors who enter by the pavilion reserved for carriages pass through a hallway where ticket offices are situated.
The larger number of the audience, before entering the auditorium, traverse a large circular vestibule located exactly beneath it.
The ceiling of this portion of the building is upheld by sixteen fluted columns of Jura stone, with white marble capitals, forming a portico.
Here servants are to await their masters, and spectators may remain until their carriages are summoned.The third entrance, which is quite distinct from the others, is reserved for the Executive.
The section of the building set aside for the use of the Emperor Napoleon was to have included an antechamber for the bodyguards;a salon for the aides-de-camp; a large salon and a smaller one for the Empress; hat and cloak rooms, etc.Moreover, there were to be in close proximity to the entrance, stables for three coaches, for the outriders' horses, and for the twenty-one horsemen acting as an escort; a station for a squad of infantry of thirty-one men and ten cent-gardes, and a stable for the horses of the latter;and, besides, a salon for fifteen or twenty domestics.Thus arrangements had to be made to accommodate in this part of the building about one hundred persons, fifty horses, and half-a-dozen carriages.
The fall of the Empire suggested some changes, but ample provision still exists for emergencies.
