This story does not hold water: it would be difficult to form a mask out of a napkin; the Bastille had a resident surgeon of its own as well as a physician and apothecary; no one could gain access to a prisoner without a written order from a minister, even the Viaticum could only be introduced by the express permission of the lieutenant of police.
This theory met at first with no objections, and seemed to be going to oust all the others, thanks, perhaps, to the combative and restive character of its promulgator, who bore criticism badly, and whom no one cared to incense, his sword being even more redoubtable than his pen.
It was known that when Saint-Mars journeyed with his prisoner to the Bastille, they had put up on the way at Palteau, in Champagne, a property belonging to the governor. Freron therefore addressed himself to a grand-nephew of Saint-Mars, who had inherited this estate, asking if he could give him any information about this visit. The following reply appeared in the 'Annee Litteraire (June 1768):—
"As it appears from the letter of M. de Sainte-Foix from which you quote that the Man in the Iron Mask still exercises the fancy of your journalists, I am willing to tell you all I know about the prisoner. He was known in the islands of Sainte-Marguerite and at the Bastille as 'La Tour.' The governor and all the other officials showed him great respect, and supplied him with everything he asked for that could be granted to a prisoner. He often took exercise in the yard of the prison, but never without his mask on. It was not till the 'Siecle' of M. de Voltaire appeared that I learned that the mask was of iron and furnished with springs; it may be that the circumstance was overlooked, but he never wore it except when taking the air, or when he had to appear before a stranger.
"M. de Blainvilliers, an infantry officer who was acquainted with M. de Saint-Mars both at Pignerol and Sainte-Marguerite, has often told me that the lot of 'La Tour' greatly excited his curiosity, and that he had once borrowed the clothes and arms of a soldier whose turn it was to be sentry on the terrace under the prisoner's window at Sainte-Marguerite, and undertaken the duty himself; that he had seen the prisoner distinctly, without his mask; that his face was white, that he was tall and well proportioned, except that his ankles were too thick, and that his hair was white, although he appeared to be still in the prime of life. He passed the whole of the night in question pacing to and fro in his room. Blainvilliers added that he was always dressed in brown, that he had plenty of fine linen and books, that the governor and the other officers always stood uncovered in his presence till he gave them leave to cover and sit down, and that they often bore him company at table.
"In 1698 M. de Saint-Mars was promoted from the governorship of the Iles Sainte-Marguerite to that of the Bastille. In moving thither, accompanied by his prisoner, he made his estate of Palteau a halting-place. The masked man arrived in a litter which preceded that of M. de Saint-Mars, and several mounted men rode beside it. The peasants were assembled to greet their liege lord. M. de Saint-Mars dined with his prisoner, who sat with his back to the dining-room windows, which looked out on the court. None of the peasants whom I have questioned were able to see whether the man kept his mask on while eating, but they all noticed that M. de Saint-Mars, who sat opposite to his charge, laid two pistols beside his plate; that only one footman waited at table, who went into the antechamber to change the plates and dishes, always carefully closing the dining-room door behind him. When the prisoner crossed the courtyard his face was covered with a black mask, but the peasants could see his lips and teeth, and remarked that he was tall, and had white hair. M. de Saint-Mars slept in a bed placed beside the prisoner's. M. de Blainvilliers told me also that 'as soon as he was dead, which happened in 1704, he was buried at Saint-Paul's,' and that 'the coffin was filled with substances which would rapidly consume the body.' He added, 'I never heard that the masked man spoke with an English accent.'"
Sainte-Foix proved the story related by M. de Blainvilliers to be little worthy of belief, showing by a circumstance mentioned in the letter that the imprisoned man could not be the Duc de Beaufort; witness the epigram of Madame de Choisy, "M. de Beaufort longs to bite and can't," whereas the peasants had seen the prisoner's teeth through his mask. It appeared as if the theory of Sainte-Foix were going to stand, when a Jesuit father, named Griffet, who was confessor at the Bastille, devoted chapter xiii, of his 'Traite des differentes Sortes de Preuves qui servent a etablir la Verite dans l'Histoire' (12mo, Liege, 1769) to the consideration of the Iron Mask. He was the first to quote an authentic document which certifies that the Man in the Iron Mask about whom there was so much disputing really existed. This was the written journal of M. du Jonca, King's Lieutenant in the Bastille in 1698, from which Pere Griffet took the following passage:—
"On Thursday, September the 8th, 1698, at three o'clock in the afternoon, M. de Saint-Mars, the new governor of the Bastille, entered upon his duties. He arrived from the islands of Sainte-Marguerite, bringing with him in a litter a prisoner whose name is a secret, and whom he had had under his charge there, and at Pignerol. This prisoner, who was always masked, was at first placed in the Bassiniere tower, where he remained until the evening. At nine o'clock p.m. I took him to the third room of the Bertaudiere tower, which I had had already furnished before his arrival with all needful articles, having received orders to do so from M. de Saint-Mars. While I was showing him the way to his room, I was accompanied by M. Rosarges, who had also arrived along with M. de Saint-Mars, and whose office it was to wait on the said prisoner, whose table is to be supplied by the governor."
Du Jonca's diary records the death of the prisoner in the following terms:—
"Monday, 19th November 1703. The unknown prisoner, who always wore a black velvet mask, and whom M. de Saint-Mars brought with him from the Iles Sainte-Marguerite, and whom he had so long in charge, felt slightly unwell yesterday on coming back from mass. He died to-day at 10 p.m. without having a serious illness, indeed it could not have been slighter. M. Guiraut, our chaplain, confessed him yesterday, but as his death was quite unexpected he did not receive the last sacraments, although the chaplain was able to exhort him up to the moment of his death. He was buried on Tuesday the 20th November at 4 P.M. in the burial-ground of St. Paul's, our parish church. The funeral expenses amounted to 40 livres."
