The magician Adam du Coeuret – also known as Lesage – remained in Paris for several years, working with Catherine Monvoisin – or La Voisin – among Paris’s network of abortionists, poisoners, sorcerers and fortune tellers. On 22 March 1679, he was arrested in connection with the scandal known thereafter as the Affair of the Poisons, in which Parisian police unearthed what they feared was a plot to poison King Louis XIV. As a recidivist on charges of sacrilege, Lesage faced execution if guilty, but when the Chambre Ardente established to investigate the affair was dissolved in 1682, Lesage was imprisoned without trial for the rest of his life in the Chateau de Besançon. The date of his death is unknown.
The fortune teller and abortionist Catherine Monvoisin was arrested on 12 March 1679 on suspicion of involvement in a plot to poison King Louis XIV and for her role in black masses designed to secure for Athénaïs de Montespan the affections of King Louis XIV. She confessed to witchcraft and was burned alive on 22 February 1680.
In March 1680, the daughter of Catherine Monvoisin, Marie-Marguerite Monvoisin, was interrogated and described all she knew of her mother’s involvement in an alleged plot to poison Louis XIV. Although only in her early twenties and not charged with any offences, she was imprisoned without trial for the rest of her life on the island prison of Belle-Île-en-Mer. As with other female prisoners jailed in the affair, she was guarded by women to ensure she could not use her feminine wiles to escape. The date of her death is unknown.
Athénaïs de Montespan, King Louis XIV’s official mistress, or maîtresse-en-titre, had several children with Louis XIV over the course of their thirteen-year relationship. These children were recognised officially by Louis in December 1673, several months after the black mass conducted for that purpose by Lesage, Abbé Guibourg and Catherine Monvoisin. Although numerous people arrested in the Affair of the Poisons mentioned Madame de Montespan in connection with the sorcerers of Paris, there was never any proof of her involvement in witchcraft. In 1691, Madame de Montespan retired to a convent, where she died in 1707 at the age of sixty-six.
Françoise Filastre was arrested in December 1679 and burned alive in October 1680 for practising witchcraft.
Nothing further was heard of Charlotte Picot, although mention of a prophetess living in a forest near Lyon by the seventeenth-century English essayist Joseph Addison could be a reference to her.
