L'affaire des Poisons, King Louis XIV and Madame de Montespan

Poison, potions, death, magic, a dash of witchcraft and a royal mistress make for a fascinating moment in French history

How L'affaire des Poisons Began

L’affaire des poisons consumed the French royal court in the late 1670s and early 1680s during King Louis XIV’s reign. Accusations abounded of witchcraft, the use of potions and poisons known as “inheritance powders,” suspicious deaths, seemingly improbable passions and alliances.

In 1675 Marie-Madeleine, Marquise de Brinvilliers was placed on trial and found guilty of poisoning her father and brothers so that she and her lover Godin de Saint-Croix would inherit all of the family’s wealth. Her assertion that “Half the people of quality are involved in this sort of thing, and I could ruin them if I were to talk” created fear and paranoia in aristocratic circles. She was exaggerating but there was merit to her statement.

La Chambre Ardente: The Burning Chamber

Towards the end of the 1670s, King Louis installed Gabriel Nicolas de la Reynie (1625-1709) as Le Premier Lieutenant Général De Police De Paris and as the leader of a special new commission La Chambre Ardente (in English, The Burning Chamber) to establish how much truth lay in the rumours of foul play that included a death threat against the king.

During the three years that La Chambre Ardente operated the commission sat in an oppressive chamber that had black cloths over the windows and limited torchlight under which suspects were questioned and quaked.

It was a busy commission. During the 1600s it was not uncommon for magic to be suspected as a device for self-advancement. Murdering the courtiers in your path who blocked access to the king and his favour was not as unbelievable as it is today.

Women were charged with using magic, normally love charms and potions, much more often than men. Even the less honourable priests of the era sold potions and spells. Superstitions controlled actions to a bewildering degree.

Athénaïs, Madame de Montespan Implicated in a Murder

King Louis XIV’s long term chief-mistress (maitresse-en-titre) Athénaïs, Francoise-Athénaïs de Rochechouart de Mortemart, Marquise de Montespan (1740-1707) was often called Madame de Montespan or La Montespan. She did not make it through the scandal unscathed.

Athénaïs had felt threatened at first by a rival for the king’s affections named Marie-Angélique de Scorailles de Roussille, Duchesse de Fontanges. When Marie-Angélique died aged nineteen many at court believed that Athénaïs had arranged or carried out a murder, probably using poison. However, there was a flaw in their theory.

By the time of her death Marie-Angélique had lost her initial allure and was ailing. Louis was frustrated that she refused to accept her moment as the Sun King’s favourite was over. He expected her to remove herself from the court.

No proof was ever uncovered of Athénaïs’ involvement in Marie-Angélique or anyone else's death but what damned her was her connection, as a client, to the love potion maker, abortionist, poisoner and alleged witch Catherine Deshayes Monvoisin, La Voisin.

Confused Testimonies

La Voisin’s associate Adam Couret, also known as Lesage, identified Madame de Montespan as La Voisin’s client. Marguerite, La Voisin’s daughter, testified that La Montespan’s former servant, briefly Louis’ lover, Mademoiselle Claude de Vin des Œillets was the woman who collected the poison but later she contradicted herself by saying that it was Athénaïs who visited her mother. Mademoiselle des Œillets denied involvement and suggested that the person who had paid the visits to La Voisin’s premises must have resembled her.

Françoise Filastre, the late Duchesse de Fontanges’ servant was a friend of La Voisin and a poisoner known by the name of La Filastra. In her testimony, she accused Athénaïs of employing her to murder Marie-Angélique and named Abbé Etienne Guibourg (1610-1686) as the priest who carried out black masses for her.

The abbé confessed that he officiated at three black masses but he had no recollection of when these took place. He conceded that as he never saw the face of his female client it might not have been Athénaïs. Françoise Filastre subsequently retracted her statement.

Athénaïs’ and La Chambre Ardente

It was claimed that in 1665 La Voisin had concocted love potions for Athénaïs so that Louis XIV would fall in love with her. As the king and Athénaïs’ relationship began in earnest in 1667 this was seen by some contemporaries as proof enough that she was guilty of her rivals murder.

As Athénaïs was accused of placing ground infant bones in Louis’ food, taking black masses and committing infanticide to achieve her objective, Louis was shaken. He banned all public attendance at Athénaïs' hearing. Fortunately, Athenaïs had never shown a desire to commit regicide so the accusation of attempting to kill Louis was dismissed.

La Voisin was arrested for poisoning the king for over a decade. The absence of Athénaïs’ arrest or a trial suggested to more cynical onlookers that there was a cover-up.

Judgements Handed Down

La Filastra and La Voisin were burnt at the stake in 1680. Allegedly, La Voisin pushed the priest away at the execution site. The abbé was sentenced to life imprisonment and his possessions were claimed by the state. Thirty-six people were executed by the conclusion of the La Chambre Ardente’s proceedings in 1682. Several key courtiers were saved by the king from trials.

Louis XIV created incontestable lettres de cachet issuing fines, imprisonment terms, galley service orders, exiles and banishments from France. He passed a new law in 1682 that all magic was fraudulent and the sale of poisons was to be state governed but not outlawed.

Madame de Montespan Replaced

Louis XIV regarded Athénaïs in a different light after L'affaires des poisons and his passion faded. She was dismissed from his side but he still paid her frequent visits. In her memoirs written during her retirement, she noted that “The king...did not, on that account, return to that sweet and agreeable intimacy which had united us for the space of eleven or twelve years. He approached me as one comes to see a person of one's acquaintance...”

Louis was concerned about his popularity and the sensible Françoise de Maintenon became his new maîtresse-en-titre. The king secretly married Françoise in either October 1683 or January 1684 after the death of his wife Queen Maria Theresa. Athénaïs committed herself to charitable and virtuous causes as she grew uncertain in her twilight years whether her past behaviour had cost her her chance in heaven. To some people, she was still guilty of murder.
