Still the Inquisition was not wholly without evidence of activity in its purposed sphere of duty. We shall see hereafter that Pierre d’Ailly, Bishop of Cambrai, when, in 1411, he prosecuted the Men of Intelligence, duly called in the inquisitor of the province, who was Dominican Prior of St. Quentin in Vermandois, to join in the sentence. In 1430 we hear of a number of heretics who had been burned at Lille by the deputy-inquisitor and the Bishop of Tournay; and in 1431 Philippe le Bon ordered his officials to execute all sentences pronounced by Brother Heinrich Kaleyser, who had been appointed Inquisitor of Cambrai and Lille by the Dominican Provincial of Germany--a manifest invasion of the rights of his colleague of Paris, doubtless due to the political complications of the times. This order of Philippe le Bon, however, shows that the example of supervision set by the Parlement was not lost on the feudatories, for the officials are only instructed to make arrests when there has been a proper preliminary inquest, with observance of all the forms of law. I shall have occasion hereafter to speak of the part played by the Inquisition in the tragedy of Joan of Arc, and need here only allude to the appointment, in 1431, by Eugenius IV., of Frère Jean Graveran to be Inquisitor of Rouen, where he was already exercising the functions of the office, and where he was succeeded in 1433 by Frère Sébastien l’Abbé, who had been papal penitentiary and chaplain--another evidence of the partition of France during the disastrous English war. People were growing more careless about excommunication than ever. About 1415, a number of ecclesiastics of Limoges were prosecuted by the inquisitor, Jean du Puy, as suspect of heresy for this cause; they appealed to the Council of Constance, and in 1418 the matter was referred back to the archbishop. Still the indifference to excommunication grew, and in 1435 Eugenius IV. instructed the Inquisitor of Carcassonne to prosecute all who remained under the censure of the Church for several years without seeking absolution.[158]
