No less than forty-eight works are said to have been written on the imprisonment of Louis XVII., and matters connected with it, including the histories of some dozen "claimants," asserting, in his name, their right to the French throne. Most of these pretenders, with Naundorff--who had been the Dauphin's valet in the Temple--prominent among them, had no difficulty in finding enthusiasts and dupes to further their designs; and even in France one of them caused himself to be described on his tombstone as "Louis de France." The Emperor Napoleon III. took, however, the liberty of ordering the inscription to be effaced. Soon after the death of the Count de Chambord, M. de Chantelauze published in the _Illustration_ an account of Louis XVII.'s life in the Temple, and of his last illness, death, and post-mortem examination, together with certificates which leave no doubt as to the young prince having really died in his prison. Simon, the gaoler, according to M. de Chantelauze's view, was, like so many other bad men, not wholly bad; while his wife was for the most part good, the appearance of badness or roughness which she manifested when the child confided to her care was visited by members of the Commune being assumed in order to inspire her employers with confidence. The task assigned to Simon was not, as has often been supposed, to reduce the young prince, by ill-treatment, to such a point that he would at last be attacked by illness and carried off, but simply to get from him evidence against his mother, the Queen, with respect to her complicity in the Varennes plot, and the various plans formed for effecting the escape of the child. The evidence having been obtained by the simple process of first putting it into the child's mouth, and afterwards taking it out, the special work assigned to the Simons was at an end, and the young prince experienced from them nothing but kindness. If he ultimately fell ill and died, his confinement and the bad air he breathed may well have been the cause. The life of Louis XVII., from the departure of the Simons until his death, can be made out continuously; and the evidence of his having died in the Temple is quite conclusive. Nevertheless, Louis XVIII., in view of the pretension constantly springing up, instituted for his own satisfaction an inquiry into the whole matter; and the proofs adduced in the course of it as to the identity of the "child in the Temple" with the son of Louis XVI. and Marie Antoinette seem decisive. M. Nauroy, however, author of "Les Secrets des Bourbons," is convinced that the true Louis XVII. was carried out of the Temple in a bundle of linen, and that by like means the child who ultimately died there was substituted for him. M. Nauroy finds in support of his belief abundant evidence, positive and negative, which he derives from a variety of sources, and sometimes discovers in the most unexpected places.
