The influence of the clergy of Paris obliged the Court to explain itself concerning the causes of my imprisonment, by the mouth of the Chancellor, who, in the presence of the King and Queen, acquainted them that his Majesty had caused me to be arrested for my own good, and to prevent me from putting something that I designed into execution.  The chapter of Notre-Dame had an anthem sung every day for my deliverance.  The Sorbonne and many of the a religious orders distinguished themselves by declaring for me.  This general stir obliged the Court to treat me somewhat better than at first.  They let me have a limited number of books, but no ink and paper, and they allowed me a ‘valet de chambre’ and a physician.

During my confinement at Vincennes, which lasted fifteen months, I studied both day and night, especially the Latin tongue, on which I perceive one cannot bestow too much pains, since it takes in all other studies.  I dived into the Greek also, and read again the ninth decade of Livy, which I had formerly delighted in, and found as pleasant as ever.  I composed, in imitation of Boetius, a treatise, which I entitled “Consolation de la Theologie,” in which I proved that every prisoner ought to endeavour to be ‘vinctus in Christo’ (in the bonds of Christ), mentioned by Saint Paul.  I also compiled “Partus Vincennarum,” which was a collection of the Acts of the Church of Milan for the use of the Church of Paris.

My guard omitted nothing he could invent to make my life uneasy and disturb my studies.  One day he came and told me that he had received orders from the King to give me an airing on the top of the donjon; and when he perceived that I took a pleasure in walking there, he informed me, with joy in his looks, that he had orders to the contrary.  I told him that they were come in good time, for the air, which was too sharp there, had made my head ache.  Afterwards he offered to take me down into the tennis-court to see my guards at play.  I desired him to excuse me, because I thought the air would be too piercing for me; but he made me go, telling me that the King, who took more care of my health than I fancied, had ordered that he should give me some exercise.  Soon after he desired me to excuse him for not bringing me down again, “for reasons,” said he, “which I must not tell.”  The truth was, I was so much above these chicaneries that I despised them; but I must own that I used to think within myself that, in the main, to be a prisoner of State was of all others the most afflicting.  All the relaxation I had from my studies was to divert myself with some rabbits on the top of the donjon, and some pigeons in the turrets, for which I was indebted to the continual solicitations of the Church of Paris.  I had not been a prisoner above nine days when one of my guards, while his comrade who watched me was asleep, came and slipped a note into my hand from Madame de Pommereux, in which were only these words:  “Let me have your answer; you may safely trust the bearer.”  The bearer gave me a pencil and a piece of paper, on which I wrote that I had received her letter.
