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 Penitence_ or the _Pedagogue chretien_. 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.
