But under the glittering shows of wealth La Voisin had preserved most dissolute manners. She was constantly drunk. She indulged in fishwife’s brawls with Lesage. Latour, who was her ‘great author,’ used to thrash her. She fought with Marie Bosse and tore her hair out. ‘One day, Latour being with her on the ramparts, she got him to give her husband fifty blows with a stick, while she held Latour’s hat.’ On that occasion, Latour bit poor Monvoisin’s nose. But on the other hand, the sorceress regularly attended the church of the Abbé de Saint-Amour, rector of the University of Paris, an austere Jansenist; and Madame de la Roche-Guyon stood god-mother to her daughter.

The husband whom La Voisin so brutally got beaten, appears to have been a decent man. In those days there was at Montmartre a chapel dedicated to St. Ursula, who enjoyed the power to ‘improve’ husbands. The procedure was to carry there, some Friday morning, a shirt of the wicked spouse. Our sorceress had the most implicit faith in the efficacy of this practice, and we must do her the justice to state that she always began by sending to Montmartre women who came to her with tales of their troubles. She availed herself of the remedy on her own account, and poor Monvoisin had to march to the place carrying his shirt under his arm. He was a husband for whose improvement St. Ursula does not appear to have been required to spend much effort.

Lesage, the witch’s lover, advised her to get rid of Monvoisin. A sheep’s heart was bought, ‘to which Lesage did something,’ and then it was buried in the garden behind the gate. Lo and behold, Monvoisin was seized with severe pain in the stomach. He cried out that if there was anybody who wished to do for him, he had better shoot him at once instead of letting him linger. La Voisin, struck with remorse, hastened to the Augustines to confess and obtain a general absolution; she took the sacrament, and on her return compelled Lesage to undo his wicked charms.

She related very simply and frankly to La Reynie the first steps of her career. Her husband, at that time, was doing nothing, but he had been a hawking jeweller, and then a shopkeeper on the Pont-Marie. He had lost his shop, and then, seeing her husband ruined, ‘she had devoted herself to cultivating the powers that God had given her.’ ‘It was chiromancy and face-reading that I learnt at the age of nine. I have been persecuted for fourteen years: that is the work of the missionaries’ (these were the members of a community established by St. Vincent de Paul, then very popular, who were actively occupied in converting sinners and removing scandals of all kinds). ‘However,’ she continued, ‘I gave an account of my art to the vicars-general, the Holy See being vacant, and to several doctors of the Sorbonne to whom I had been sent, and they found nothing to object to.’ Marie Bosse also spoke of the time when her friend went to the Sorbonne to argue on astrology with the professors.

Thus La Voisin set up as fortune-teller in order to restore order and comfort to her household. One of her friends, La Lepère, told her sometimes that she ought not to engage in such great crimes. ‘You are mad!’ cried the witch, ‘the times are too bad. How am I to feed my family? I have six persons on my hands!’ And in fact, until her arrest, La Voisin had been the constant support of her old mother, to whom she gave money every week.

La Voisin’s claim that her art was founded on face-reading was quite genuine. She had made a profound study of physiognomy. We find innumerable references to this subject in the documents of her case, and also a ‘Treatise on physiognomy, supported on six immovable columns: (1) sympathy between body and mind; (2) relations between rational and irrational animals; (3) the differences between the sexes; (4) national diversities; (5) physical temperaments; (6) diversities of age; not depending on a single sign, for men are often attacked by some defect which force of mind, aided by grace, can assuredly overcome.’ When the Countess de Beaufort de Canillac came to consult the fortune-teller, ‘the lady wishing to give me her hand without unmasking, I told her that I did not know physiognomies of velvet, whereupon the lady removed her mask.’ La Voisin confessed that she read much more in the features than in the lines of the hand, ‘it being no easy thing to conceal a passion or any considerable disturbing emotion.’ She was not merely a physiognomist, but an expert psychologist, and that was how she gave a real foundation to her sorcery. We may cite the following incident among many others.

Marie Brissart, widow of a Parlement counsellor, tenderly loved and handsomely supported a captain of guards named Louis Denis de Rubentel, Marquis de Mondétour, who became lieutenant-general in 1688. He was a personage of whom Saint-Simon, a severe censor, speaks thus: ‘He had been able to contemn basenesses, and to withdraw into his virtue, which was beyond his wealth.’ Madame Brissart used to send him money when he was on service, after having equipped him from top to toe on his departure. It happened that the cavalier displayed some coldness towards his mistress, with the idea of getting her purse to open still more generously. The widow, seeing nothing of her captain, became alarmed, and hastened to La Voisin. She began her incantations, with the assistance of Lesage. The magician walked up and down the garden with a wand, with which he struck the earth, repeating the words, Per Deum sanctum, per Deum vivum! Then he said: ‘Louis Denis de Rubentel, I conjure thee in the name of the Almighty to go find Marie Miron (Madame Brissart’s maiden name): she to possess thee wholly, body, soul, and spirit, and thou to love none but her!’ On another occasion, he put into a little ball of wax a paper on which the names of Rubentel and Madame Brissart were written, and in the presence of the latter threw the ball into the fire, where it burst with a loud noise. These fine charms were still without result, when one morning La Voisin, with the intuition of a clairvoyant, said to her weeping client: ‘You write every day and send your maid to Rubentel, but he pays no attention to you; it is mad conduct to write and send every day'; and the lady having ceased to write and send, Monsieur de Rubentel, who in turn began to be afraid lest so precious a fount should dry up, returned to her ‘without anything else having been done; yet the lady, believing that La Voisin had done some extraordinary thing, gave her twelve pistoles.’

The witch heard all sorts of confessions. There were wonderful dreams of adoring affection told her by lovers of twenty years, who came to her red with emotion, or wrote thrilling letters in order to bring their torment to an end, begging her to soften the hard hearts of their mistresses, or to bend the opposition of a cruel father. Or it was the fierce carnal love of mature women obstinately clinging to the lovers who were neglecting them for fresher girls. There were also the passions of ambitious women, greedy for money and honours, which bring us to the horrors of the ‘black mass.

La Voisin was assisted in these monstrous rites by a priest ‘squint-eyed and old,’ with bloated face, and prominent blue veins forming a network on his cheeks—the terrible Abbé Guibourg. Formerly chaplain to the Count de Montgommery, he was at this time sacristan of St. Marcel, at St. Denis. He used to say mass, according to the proper rites, wearing the alb, stole, and maniple. ‘The women on whose bodies mass was said were laid stark naked, without even their chemise, upon a table which served as altar; their arms were stretched out, and they held a taper in each hand.’ Sometimes they did not actually undress themselves, ‘but only tucked up their garments as high as the throat.’ The chalice was placed on the bare belly. At the moment of the offertoire, a child had its throat cut. Guibourg usually stuck a long needle into its neck. The blood of the expiring victim was poured into the chalice, and mixed with the blood of bats and other materials obtained by filthy means. Flour was added to solidify the mess, which was thus made to resemble the Host, to be consecrated at the moment when, in the sacrifice of the mass, transubstantiation takes place. The scene is reconstructed by La Reynie according to the testimony of the accused.

Black masses were not the only sorceries whose rites required the sacrifice of children. La Voisin and her fellow-witches perpetrated a terrible slaughter of them. Children deserted by their unmarried mothers, others bought from poor women, did not suffice: several sorceresses were convicted of having killed their own children for these atrocious proceedings. Here, for instance, is a horrible detail: the daughter of La Voisin, on the very eve of her trouble, not trusting her mother, fled the house, and only returned after placing her infant in safety. The witches ran off with children in the streets. La Reynie wrote to Louvois: ‘Remember the great disturbance in Paris in 1676, when there were seditious gatherings and mobs and runnings to and fro in several parts of the city, through the rumour that people carried off children to cut their throats, though no one then understood what the cause of the rumour could be. The mob, however, proceeded to various excesses against the women suspected of being child-stealers. The king ordered an inquiry. Proceedings were taken (against those who rose against the witches), and a woman who was guilty of violence was condemned to death, but obtained a special pardon.’
