From Mme. de Scudéry to Bussy, October 29, 1679: "A diversion has been established for Mme. de Montespan for this winter, and provided that she can do without love, she will retain the consideration of the King. This is all that an honest man can do when he ceases to love." Bussy responded, November 4th: "If Mme. de Montespan is wise she will dream only of cards and will leave the King in peace on the subject of love; for it is impossible through complaints and scoldings to lure back unfaithful lovers."

Mme. de Montespan was not wise. In the hope of bringing the King back to her arms by force, she redoubled the disagreeable scenes. At this moment, an obscure past, filled with vague and frightful events, rose against her, and the expiation for having too much loved became almost tragic in its character.

La Voisin, the poisoner, cannot be forgotten, nor the prosecution in 1668, which had revealed to the young King the connection of his new mistress with the world of malefactors. This affair was stifled, but the evil continued in its subterranean influence. The merchants of love philters and of poisons and the priests of satanic rites saw their clients increasing in number year by year. When the crimes finally came to the surface, and Louis established (March 7, 1679) the "Chambre ardente" to purify France from the gangrene, so many Parisians were connected in one way or another with the accused that the King had against him a powerful current of opinion. This is, perhaps, the most significant feature of the sad affair. Instead of being crushed with shame in learning how many were compromised, the higher classes were indignant against the equal justice which refused to give them special consideration. They murmured loudly, and for once the people were with them, for the populace remained staunch to the sorcerers. The clamours were so menacing that the judges of the "Chambre ardente" felt themselves in danger: "I know," wrote Bussy-Rabutin on April 1st, "the chamber instituted to examine the 'corrupters,' and also know that Messieurs de Bezons and de La Reynie do not pass from Paris to Vincennes without an escort of the Kings Guards."[286] Louis XIV. was obliged several times to strengthen the resolution of these judges; sometimes in openly commanding them to "judge truly"[287] without any distinction of person, condition, or sex; sometimes by assuring them through official letter of his "protection."[288]

The first executions before the Chambre ardente took place in February, 1679, and the list of the names of those arrested or of those to whom notices of warrants to appear as witnesses had been served, a list which made so great an excitement on account of the aristocrats included,[289] is dated January 23, 1680. It had been at least four months before,[290] that there had come to the ears of the King, as some one was reading to him the account of the last examinations, two familiar names. Who is Mlle. des Œillets, ancient "follower" of Mme. de Montespan? Who is Cato, her maid, and what had they to do with La Voisin and with those like her? These same names again appearing in the list of January 6, 1680, the King, while declaring that the witnesses must certainly have lied,[291] ordered the Procurer-General, M. Robert, "to pay strict attention to this particular case."

This was done, with the result that Louis was forced to ask himself if the woman whom he adored above all others, and who had borne him seven children, was a vile "corrupter"; if this perfect body for which he had risked the safety of his soul had taken part in the ignoble ceremonies of the infamous Guibourg? If, discontented with the thought of sharing his favours with rivals, she might not in an access of jealousy have tried to poison him, the King? He sought the truth, but did not find it. In waiting further developments, Louis led his mistress with him wherever he might go, and she was always making a disturbance of some sort. The King grew less patient; that was the only difference.

From Bussy-Rabutin, May 18, 1680:

"The King ... as he was mounting into his carriage with the Queen had some rough words with Mme. de Montespan, about the scents with which she deluged herself, which made his Majesty ill. The King at first spoke politely, but as she responded sharply, his Majesty grew warm." On the 25th, Mme. de Sévigné noted another "serious embroilment." This time Colbert succeeded in reconciling them. The situation grew painful. A long series of letters and mémoires have been found in which La Reynie discusses for the King the charges accumulated against Mme. de Montespan. The picture is given of the doubts and fluctuations of an honest man whose responsibilities somewhat rankle in his breast, and who sees an equal peril in dishonouring the throne and in permitting a guilty woman to remain near the King. Louis passed through many successive stages of conviction during the prosecution. The further the examination proceeded, the stronger became the presumption of guilt, without, however, bringing positive proofs.

On July 12, 1680, La Reynie summed up for his master the history of the "petition to be used in poisoning the King." On October 11th he declared that he should be ruined in the affair, and supplicated his Majesty to reflect whether it would be for the "welfare of the State," to make these "horrors" public. In the month of May following, he avowed that he had erred on some points and that there was more evil than at first appeared. The marvellous control that Louis possessed over himself prevented outward betrayal; but certainly these uncertainties, these inferior conflicts, and it is to be hoped some sense of shame and remorse, became chastisements for his faults. On her side, Mme. de Montespan, in spite of the secret of her possible guilt being well guarded both at Court and by the judges and police, could not be ignorant that Mlle. des Œillets had been interrogated, confronted with witnesses, and imprisoned for life in the general Hospital at Tours.[292] Mme. de Montespan then knew that she had been denounced, but with what proof? What did the King think? What curious meetings between these two beings must have taken place. What conversations during which the King and his mistress were closely observing each other.

Court life, nevertheless, pursued its monotonous course, and Mme. de Montespan continued to figure in positions of honour. In March, 1689, she goes to meet the Dauphin[293] with the rest of the Court, and it is she who has charge of the choice and arrangement of the wedding presents, "being the woman in the world," wrote Mademoiselle, "who knows the best forms." In July, the King led her to Versailles with her sister, Mme. de Thianges, and her niece, the beautiful Duchesse de Nevers. This lady the mother and aunt were cynically offering to the Monarch.[294] In February, 1681, "a lottery was opened at Mme. de Montespan's, of which the largest prize was one hundred thousand francs, and there were a hundred others offered of one hundred pistoles each." In July, 1682, the Chambre ardente was suddenly suppressed. Of the three hundred accused, thirty-six people of no importance had been executed, one hundred sent to the galleys, or to prisons, or convents, or exiled; the noted among them always gaining some concessions. The dungeons of Paris and Vincennes were crowded. The smaller fry were released, and the remainder were scattered, without any other trial, through the provincial prisons, to await a death rarely slow in coming to relieve their misery.
