A refuge had been founded as early as Henry IV.'s reign in an old abbey in the Faubourg St. Marcel, for old and disabled soldiers. Louis XIV., the greatest creator of _invalides_ France had seen, determined in 1670 to extend the foundation, and erect a vast hospital, capable of accommodating his aged, crippled or infirm soldiers. Bruant and J.H. Mansard[148] among other architects were employed to raise the vast pile of buildings which, when completed, are said to have been capable of housing 7,000 men. A church dedicated to St. Louis was comprehended in the scheme, and, in 1680, a second Eglise Royale was erected, whose gilded dome is so conspicuous an object in south Paris; the Eglise Royale, which Mansard designed, was subsequently added to the church of St. Louis, and became its choir. Louis XIV., anticipating Napoleon's maxim that war must support war, raised the funds needed for the foundation by ingeniously requiring all ordinary and extraordinary treasurers of war to retain two deniers[149] on every livre that passed through their hands. [Footnote 148: Jules Hardouin, the younger Mansard, was a nephew and pupil of Francois Mansard, and assumed his uncle's name. The latter was the inventor of the Mansard roof.] [Footnote 149: The sixth part of a sou.] The old city gates of the Tournelle, Poissonniere (or St. Anne), St. Martin, St. Denis, the Temple, St. Jacques, St. Victor, were demolished, and triumphal arches, which still remain, erected to mark the sites of the Portes St. Denis and St. Martin. Another arch, of St. Antoine, was designed to surpass all existing or ancient monuments of the kind, and many volumes were written concerning the language in which the inscription should be composed, but the devouring maw of Versailles had to be filled, and the arch was never completed. The king for whose glory the monument was to be raised, cared so little for it, that he suffered it to be pulled down.
