[Footnote 164: A whole library has been written concerning the identity of this famous prisoner. There is little doubt that the mask was of velvet and not of iron, and that the mysterious captive who died on 19th November 1703 in the Bastille, was Count Mattioli of Bologna, who was secretly arrested for having betrayed the confidence of Louis XIV.] The Bastille, which in the time of the English rule, had seen as its captains the Duke of Exeter, Falstaff, and invincible Talbot, was first used in Richelieu's time as a permanent state prison, and filled under Louis XIV. with Jansenists and Protestants, who were thus separated from the prisoners of the common jails; and, later, under Louis XV. by a whole population of obnoxious pamphleteers and champions of philosophy. Books as well as their authors were incarcerated, and released when considered no longer dangerous; the tomes of famous _Encyclopedie_ spent some years there. From the middle of the eighteenth century the horrible, dark and damp dungeons, half underground and sometimes flooded, formerly inhabited by the lowest type of criminals, were reserved as temporary cells for insubordinate prisoners, and since the accession of Louis XIV. they were no more used. The Bastille during the reigns of the three later Louis was the most comfortable prison in Paris, and detention there rather than in the other prisons was often sought for and granted as a favour; the prisoners might furnish their rooms, and have their own libraries and food. In the middle of the seventeenth century, certain rooms were furnished at the king's expense for those who were without means. The rooms were warmed, the prisoners well fed, and sums varying from three to thirty-five francs per day, according to condition,[165] were allotted for their maintenance. A considerable amount of personal liberty was allowed to many and indemnities were in later years paid to those who had been unjustly detained. But a prison where men are confined indefinitely without trial and at a king's arbitrary pleasure is none the less intolerable, however its horrors be mitigated. Prisoners were sometimes forgotten, and letters are extant from Louvois and other ministers, asking the governor to report how many years certain prisoners had been detained, and if he remembered what they were charged with. In Louis XIV.'s reign 2228 persons were incarcerated there; in Louis XV.'s, 2567. From the accession of Louis XVI. to the destruction of the prison the number had fallen to 289. Seven were found there when the fortress was captured, the remainder having been transferred to Vincennes and other prisons by the governor who had some fears of treachery within but none of danger from without. Four were accused of forgery, two insane; one, the Count of Solages, accused of a monstrous crime, was detained there to spare the feelings of his family. So unexpected was the attack, that although well furnished with means of defence, the governor had less than
