Gilles de Rais was born at Machecoul in Brittany about the year 1404. The first period of his life was glorious; the companion and guide of Jeanne d'Arc, he became Maréchal of France and distinguished himself by many deeds of valour. But after dissipating his immense fortune, largely on Church ceremonies carried out with the wildest extravagance, he was led to study alchemy, partly by curiosity and partly as a means for restoring his shattered fortunes. Hearing that Germany and Italy were the countries where alchemy flourished, he enlisted Italians in his service and was gradually drawn into the further region of magic. According to Huysmans, Gilles de Rais had remained until this moment a Christian mystic under the influence of Jeanne d'Arc, but after her death--possibly in despair--he offered himself to the powers of darkness. Evokers of Satan now flocked to him from every side, amongst them Prelati, an Italian, by no means the old and wrinkled sorcerer of tradition, but a young and attractive man of charming manners. For it was from Italy that came the most skilful adepts in the art of alchemy, astrology, magic, and infernal evocation, who spread themselves over Europe, particularly France. Under the influence of these initiators Gilles de Rais signed a letter to the devil in a meadow near Machecoul asking him for "knowledge, power, and riches," and offering in exchange anything that might be asked of him with the exception of his life or his soul. But in spite of this appeal and of a pact signed with the blood of the writer, no Satanic apparitions were forthcoming. It was then that, becoming still more desperate, Gilles de Rais had recourse to the abominations for which his name has remained infamous--still more frightful invocations, loathsome debaucheries, perverted vice in every form, Sadic cruelties, horrible sacrifices, and, finally, holocausts of little boys and girls collected by his agents in the surrounding country and put to death with the most inhuman tortures. During the years 1432-40 literally hundreds of children disappeared. Many of the names of the unhappy little victims were preserved in the records of the period. Gilles de Rais met with a well-deserved end: in 1440 he was hanged and burnt. So far he does not appear to have found a panegyrist to place him in the ranks of noble martyrs. It will, of course, be urged that the crimes here described were those of a criminal lunatic and not to be attributed to any occult cause; the answer to this is that Gilles was not an isolated unit, but one of a group of occultists who cannot all have been mad. Moreover, it was only after his invocation of the Evil One that he developed these monstrous proclivities. So also his eighteenth-century replica, the Marquis de Sade, combined with his abominations an impassioned hatred of the Christian religion.
