The imposture being now laid so completely bare, the archbishop was convinced that the infamous persecutions to which it had led would cease at once and for ever; but Grandier, better acquainted with the character of his adversaries, arrived on the 27th of December at the abbey and laid a petition at the archbishop’s feet.  In this document he set forth that his enemies having formerly brought false and slanderous accusations, against him of which, through the justice of the archbishop, he had been able to clear himself, had employed themselves during the last three months in inventing and publishing as a fact that the petitioner had sent evil spirits into the bodies of nuns in the Ursuline convent of Loudun, although he had never spoken to any of the sisterhood there; that the guardianship of the sisters who, it was alleged, were possessed, and the task of exorcism, had been entrusted to Jean Mignon and Pierre Barre, who had in the most unmistakable manner shown themselves to be the mortal enemies of the petitioner; that in the reports drawn up by the said Jean Mignon and Pierre Barre, which differed so widely from those made by the bailiff and the civil lieutenant, it was boastfully alleged that three or four times devils had been driven out, but that they had succeeded in returning and taking possession of their victims again and again, in virtue of successive pacts entered into between the prince of darkness and the petitioner; that the aim of these reports and allegations was to destroy the reputation of the petitioner and excite public opinion against him; that although the demons had been put to flight by the arrival of His Grace, yet it was too probable that as soon as he was gone they would return to the charge; that if, such being the case, the powerful support of the archbishop were not available, the innocence of the petitioner, no matter how strongly established, would by the cunning tactics of his inveterate foes be obscured and denied:  he, the petitioner, therefore prayed that, should the foregoing reasons prove on examination to be cogent, the archbishop would be pleased to prohibit Barre, Mignon, and their partisans, whether among the secular or the regular clergy, from taking part in any future exorcisms, should such be necessary, or in the control of any persons alleged to be possessed; furthermore, petitioner prayed that His Grace would be pleased to appoint as a precautionary measure such other clerics and lay persons as seemed to him suitable, to superintend the administration of food and medicine and the rite of exorcism to those alleged to be possessed, and that all the treatment should be carried out in the presence of magistrates.

The archbishop accepted the petition, and wrote below it: 

“The present petition having been seen by us and the opinion of our attorney having been taken in the matter, we have sent the petitioner in advance of our said attorney back to Poitiers, that justice may be done him, and in the meantime we have appointed Sieur Barre, Pere l’Escaye, a Jesuit residing in Poitiers, Pere Gaut of the Oratory, residing at Tours, to conduct the exorcisms, should such be necessary, and have given them an order to this effect.
