The Inquisitor Michaelis has left us the history of this trial by exorcism. These patients had all the symptoms of convulsive hysteria, with nymphomania, catalepsy, and hallucinatory delirium. This Judge, however, only saw in these manifestations the work of several demons, who tormented these nuns one after, the other, at the instigation of the priest, Louis Gaufridi, who was arrested, tried, condemned by the executioner, and led to the gallows with a rope around his neck, in bare feet, a torch in hand; thus punished, the unfortunate and innocent priest fell into a state of dementia, and while in this condition confessed that he was the author of the nuns’ demonomania. As soon as Gaufridi had been sentenced to death by the Inquisition, the nuns of Saint Brigette’s Convent, at Lille, who had assisted at the exorcism of the nuns of Saint Ursula, in turn were attacked by hystero-demonomania. The report soon spread that they, too, were possessed, and the Inquisitor Michaelis came to Avignon to exorcise the demons. One of these nuns, Marie de Sains, suspected of sorcery, was sent to jail. Three of her companions, treated by exorcism, denounced the unfortunate girl as a witch. Marie de Sains, who, up to this time, had asserted innocence, finished by declaring herself guilty towards the rest of the nuns in the cloister. The demons found under the nuns’ beds were placed there, according to Marie’s statement, by the unfortunate Gaufridi. She testified that, “the Devil, to recompense the priest, gave him the title of ‘Prince of Magicians;’ and promised me,” added the nun, “all kinds of sovereign honors for having consented to poison the other nuns’ minds by witchcraft. Sister Joubert, Sister Bolonais, Sister Fournier, Sister Van der Motte, Sister Launoy, and Sister Peronne, who were first to have symptoms of _possession_ through diabolical power, soon fell under the action of the potent philter. The witchcraft was made with the host and consecrated blood, powdered billy goat horns, human bones, skulls of children, hair, finger-nails, flesh, and seminal fluid from the sorcerer; by adding to this mixture pieces of the human liver, spleen, and brain, Lucifer gave to the hideous melange a virtue of terrible strength. The sorcerers who gave this horrible concoction to their acquaintances not only destroyed them, but also a large number of new-born children.”
