Affair of the Poisons


The Affair of the Poisons was a major murder scandal in France during the reign of King Louis XIV. Between 1677 and 1682, a number of prominent members of the aristocracy were implicated and sentenced on charges of poisoning and witchcraft. The scandal reached into the inner circle of the king. It led to the execution of 36 people.

Context and origin

The case began in 1675 after the trial of Madame de Brinvilliers, who was accused of having conspired with her lover, army captain Godin de Sainte-Croix, to poison her father Antonine Dreux d'Aubray in 1666 and two of her brothers, Antoine d'Aubray and François d'Aubray, in 1670, in order to inherit their estates. There were also rumours that she had poisoned poor people during her visits in hospitals.
After being accused she fled, but was arrested in Liège. Madame de Brinvilliers was tortured and confessed, was sentenced to death, and on 17 July was tortured with the water cure, beheaded, and her body burned at the stake. Her alleged accomplice Sainte-Croix did not face charges because he had died of natural causes in 1672.
The sensational trial drew attention to a number of other mysterious deaths, starting a number of rumours. Prominent people, including Louis XIV, became alarmed that they might be poisoned.

Implications and investigation

The affair proper opened in February 1677 after the arrest of Magdelaine de La Grange on charges of forgery and murder. La Grange appealed to François Michel Le Tellier, Marquis of Louvois, claiming that she had information about other crimes of high importance. Louvois reported to the king, who told Gabriel Nicolas de la Reynie, who, among other things, was the chief of the Paris police, to root out the poisoners. La Reynie sought to calm the king. The subsequent investigation of potential poisoners led to accusations of witchcraft, murder and more.
Authorities rounded up a number of fortune tellers and alchemists who were suspected of selling not only divinations, séances and aphrodisiacs, but also "inheritance powders". Some of them confessed under torture and gave authorities lists of their clients, who had allegedly bought poison to get rid of their spouses or rivals in the royal court.
The most famous case was that of the midwife Catherine Deshayes Monvoisin or La Voisin, who was arrested in 1679 after she was incriminated by the poisoner Marie Bosse. La Voisin implicated a number of important individuals in the French court. These included Olympia Mancini, the Countess of Soissons, her sister, the Duchess of Bouillon, François Henri de Montmorency, Duke of Luxembourg and, most importantly, the king's mistress, Madame de Montespan.
Questioned while intoxicated, La Voisin claimed that Montespan had bought aphrodisiacs and performed black masses with her in order to gain and keep the king's favour over rival lovers. She had worked with a priest named Étienne Guibourg. There was no evidence beyond her confessions, but bad reputations followed these people afterwards. Eleanor Herman, in her book Sex with Kings, claims that the police, given reports of "babies' bones", uncovered the remains of 2,500 infants in La Voisin's garden. However, Anne Somerset disputes this in her book The Affair of the Poisons and states there is no mention of the garden being searched for human remains.
Also involved in the scandal was Eustache Dauger de Cavoye, the eldest living scion of a prominent noble family. Cavoye was disinherited by his family when, in an act of debauchery, he chose to celebrate Good Friday with a black mass. Upon his disinheritance, he opened a lucrative trade in "inheritance powders" and aphrodisiacs. He mysteriously disappeared after the abrupt ending of Louis's official investigation in 1678. Because of this and his name, he was once suspected of being the Man in the Iron Mask. However, this theory has fallen out of favour because it is now known that he was imprisoned by his family in 1679 in the Prison Saint-Lazare.

The end of the trial

La Voisin was sentenced to death for witchcraft and poisoning, and burned at the stake on 22 February 1680. Marshal Montmorency-Bouteville was briefly jailed in 1680, but was later released and became a captain of the guard. Minister Jean-Baptiste Colbert helped to hush things up.
De La Reynie re-established the special court, the Chambre Ardente, to judge cases of poisoning and witchcraft. It investigated a number of cases, including many connected to nobles and courtiers in the king's court. Over the years, the court sentenced 34 people to death for poisoning or witchcraft. Two died under torture and several courtiers were exiled. The court was abolished in 1682, because the king could not risk the publicity of such scandal. To this, Police Chief Reynie said "the enormity of their crimes proved their safeguard."

Aftermath

Perhaps the most important effect of the scandal and subsequent persecutions was the expulsion from France of the Countess of Soissons. Her son remained in France, only to find that his mother's high-profile disgrace prevented him from realising his personal ambitions, as he was effectively barred from pursuing a military career. He would eventually leave France, nurturing a profound grudge against Louis XIV, and enter the service of France's sworn enemies, the Habsburgs. Prince Eugene of Savoy, or Prinz Eugen, would, in time, come to be known as one of the greatest generals of the age and one of the factors behind the failure of Louis's bid for hegemony in Europe.

Condemned in the Poison Affair

The Poison Affair implicated 442 suspects: 367 orders of arrests were issued, of which 218 were carried out. Of the condemned, 36 were executed; five were sentenced to the galleys; and 23 to exile. This excludes those who died in custody by torture or suicide. Additionally, many accused were never brought to trial, but placed outside of the justice system and imprisoned for life by a lettre de cachet.
Of the people who were condemned to perpetual imprisonment by lettre de cachet, six women were imprisoned at Château de Villefranche; 18 men at Château de Salces; 12 women at Belle-Île-en-Mer; ten men at Château de Besançon; 14 women at St Andre de Salins; and five women at Fort de Bains.

Similar incidents

In October 1702 Marie-Anne de La Ville was arrested for having created a new organisation similar to the one of la Voisin, but because of Affair of the Poisons, she and her colleagues were never brought to trial, but imprisoned without trial on a lettre de cachet.

In fiction

The organisation of La Voisin and the Affair of the Poisons is portrayed in a novel by Judith Merkle Riley: The Oracle Glass.
The Affair of the Poisons is the leading thread throughout the second season of the French-Canadian TV series Versailles. The series shows the courtiers being intoxicated with the powders and potions; even Madame de Montespan is portrayed as having a major role in the poisonings. In the fictionalization, La Voisin was altered to the character Agathe.
