"M. de Saint-Mars," wrote the Minister, "has orders never to fail in according the respect due to your birth and to the position which you have held at Court" (December 12, 1672). From like considerations, the birth of Lauzun had brought him new furniture, but not a single object of any kind which could aid him in inventing occupation or employment.

This was the real punishment: a complete inaction with not a single echo from the outer world which might prevent his mind from continually turning inward upon itself. Lauzun only obtained a few books at long intervals, and always with great difficulty, after every page had been examined in detail; messages written in invisible ink were feared, and phrases which might throw light upon the events of the day. When the choice of literature was left to Saint-Mars, he confined himself to Le Tableau de la Pénitence or the Pédagogue chrétien. The contents of these were well known and, also, "they might be useful to lighten his despair."

It will be remembered that Mademoiselle had scolded the "little man" to make him take greater care of his person and toilet. In prison, Lauzun had grown very careless. (April 20, 1672:) "He grows so negligent that for three weeks he has worn a handkerchief knotted around his neck in place of a cravat." From note of July 30, 1672, more than seven months after his arrival: "He has not had his room swept, nor his glass rinsed; he is extremely negligent." Lauzun had permitted his beard to grow, which contributed to his neglected appearance. Saint-Mars declared that it was a half-yard long. (February 11, 1673:) "He is as disorderly at his meals as in his person and in his apartment."

Years passed. In 1673, they pruned the trees which cut off the light. This was the only change. In 1674, the prisoner almost died. His health was shattered and his temper changed. He became tranquil, except for an occasional access of anger, and was very polite to his jailer, who attributed this metamorphosis to the effects of the books of piety and the holy water freely supplied. Saint-Mars found him "very often" on his knees, saying his prayers before an image of the Virgin, and had much joy in the change.

In 1676, in the month of February, Louvois received a letter,[271] the contents of which passed through Paris like a flash of lightning. M. de Lauzun had almost succeeded in effecting his escape; and neither by door nor window, the ordinary method in romances. He had made a hole in the dungeon of Pignerol by scratching with old knives, pieces of kitchen utensils, etc., and had succeeded in piercing the thick vault below his chamber. Lauzun rolled through this opening, and found himself between four walls, before a barred window. He began again to scrape; he demolished one of the corners of the window, unfastened one of the bars, and saw that he was several fathoms above the ground. His foresight had caused him to collect a quantity of napkins, from which he made a rope ladder; "the best made in the world," wrote Mademoiselle, with admiration for the sample sent to Louvois.

He descended by this ladder to the moat surrounding the fortress, "pierced the wall on the side of the moat,"[272] encountered a rock, and recommenced at a short distance from the place of the first attempt"; the new passage led into a court of the citadel. Lauzun reached the ground one morning at daybreak. He had passed three days in scraping; it was this occupation which had kept him tranquil. Only an open door, and he would have been saved. He would well have deserved success as a reward for his industry and patience. But all was firmly closed, and he was stopped by an incorruptible sentinel.

The poor prisoner was brought back to his dungeon, and Louvois stormed at the authorities of Pignerol, who permitted walls and windows to be demolished without perceiving that anything strange was occurring. Repairs and numerous new measures of precaution were ordered, and Saint-Mars, very much abashed, swore by all the gods that such a thing should never again happen.

In spite of these oaths, many of the prisoners succeeded in gaining access to their neighbours, according to the account of Saint-Simon.[273] It seems that the open chimneys of ancient times had become an ordinary means of communication between the dungeons of Pignerol. "A hole was made in the pipe, which was carefully closed during the day," and with mutual aid the prisoners ascended and descended. Lauzun was placed in relation with various prisoners, of whom one was Foucquet, who believed him to be mad when listening to his account of the failure of the plan of marriage with the Grande Mademoiselle. These gentlemen must have resembled chimney sweeps.

Saint-Mars, however, only knew of these practices after the death of Foucquet; the troubles of Lauzun were then at an end. The death of the eldest brother, which occurred in 1677, had brought new conditions. Lauzun became head of the family. His sister, Mme. de Nogent, represented to the King that it was needful for the preservation of the "House" that M. de Lauzun should be permitted to put his affairs in order, and she had no difficulty in obtaining a hearing. Although the individual counted for little, the "House" was a thing sacred, even in the eyes of Louis XIV. Saint-Mars was ordered to receive Mme. de Nogent, another of the brothers, Chevalier de Lauzun, and their advocate, M. Isarn, and to permit them to meet with his prisoner, exacting the promise that only business should be discussed. He forbade a single word, "under any pretext whatever," of Mlle. de Montpensier. An account of these interviews, sketched by Isarn, remains. It must not be forgotten in reading this document that Lauzun had a great interest in inspiring a lively pity in the hearts of these people who were returning to Paris. After long preliminaries, Isarn arrived for the first interview with Lauzun, whom no one had seen for six years.

[October 29, 1667] Two o'clock having come, M. de Saint-Mars, after sending away all the attendants, asked M. Isarn to enter his room where six chairs were arranged around a table, and M. de Saint-Mars retiring, returned after a moment leading M. le Comte de Lauzun, supporting him by the arm, for the Comte could hardly sustain himself, it may be on account of the open air, the bright light, or the weakness caused by his illness.

At this sight, I confess, Monsieur, that we were moved with pity, for we remarked his haggard face and the extreme pallor of the countenance, as much as could be seen under the long beard and moustaches, the eyes subdued with sadness and languor, so that it would be impossible not to be moved with compassion. I can hardly express the grief of Madame his sister and Monsieur his brother. A chair near the fire was given to him, facing the window, but he shrank back, saying in a low voice, and coughing, that the bright light made his eyes and head burn. M. de Saint-Mars turned his prisoner away from the window, placing himself on one side and M. the Commissioner on the other. I was at the side of M. de Saint-Mars, having my papers before me on the table. Mme. de Nogent could not restrain her tears, and we remained some time without speaking.
