As soon as the sentence of the court was made public, all the nobility, in any degree related to the house of Van Horn, went into mourning. Another grand aristocratical assemblage was held, and a petition to the Regent, on behalf of the Count, was drawn out and left with the Marquis de Créqui for signature. This petition set forth the previous insanity of the Count, and showed that it was a hereditary malady of his family. It stated various circumstances in mitigation of his offence, and implored that his sentence might be commuted to perpetual imprisonment.

Upward of fifty names of the highest nobility, beginning with the Prince de Ligne, and including cardinals, archbishops, dukes, marquises, etc., together with ladies of equal rank, were signed to this petition. By one of the caprices of human pride and vanity, it became an object of ambition to get enrolled among the illustrious suppliants; a kind of testimonial of noble blood, to prove relationship to a murderer! The Marquis de Créqui was absolutely besieged by applicants to sign, and had to refer their claims to this singular honor, to the Prince de Ligne, the grandfather of the Count. Many who were excluded, were highly incensed, and numerous feuds took place. Nay, the affronts thus given to the morbid pride of some aristocratical families, passed from generation to generation; for, fifty years afterward, the Duchess of Mazarin complained of a slight which her father had received from the Marquis de Créqui; which proved to be something connected with the signature of this petition. This important document being completed, the illustrious body of petitioners, male and female, on Saturday evening, the eve of Palm Sunday, repaired to the Palais Royal, the residence of the Regent, and were ushered, with great ceremony but profound silence, into his hall of council. They had appointed four of their number as deputies, to present the petition, viz.: the Cardinal de Rohan, the Duke de Havré, the Prince de Ligne, and the Marquis de Créqui. After a little while, the deputies were summoned to the cabinet of the Regent. They entered, leaving the assembled petitioners in a state of the greatest anxiety. As time slowly wore away, and the evening advanced, the gloom of the company increased. Several of the ladies prayed devoutly; the good Princess of Armagnac told her beads.

The petition was received by the Regent with a most unpropitious aspect. “In asking the pardon of the criminal,” said he, “you display more zeal for the house of Van Horn, than for the service of the king.” The noble deputies enforced the petition by every argument in their power. They supplicated the Regent to consider that the infamous punishment in question would reach not merely the person of the condemned, not merely the house of Van Horn, but also the genealogies of princely and illustrious families, in whose armorial bearings might be found quarterings of this dishonored name.

“Gentlemen,” replied the Regent, “it appears to me the disgrace consists in the crime, rather than in the punishment.”

The Prince de Ligne spoke with warmth: “I have in my genealogical standard,” said he, “four escutcheons of Van Horn, and of course have four ancestors of that house. I must have them erased and effaced, and there would be so many blank spaces, like holes, in my heraldic ensigns. There is not a sovereign family which would not suffer, through the rigor of your Royal Highness; nay, all the world knows, that in the thirty-two quarterings of Madame, your mother, there is an escutcheon of Van Horn.”

“Very well,” replied the Regent, “I will share the disgrace with you, gentlemen.”

Seeing that a pardon could not be obtained, the Cardinal de Rohan and the Marquis de Créqui left the cabinet; but the Prince de Ligne and the Duke de Havré remained behind. The honor of their houses, more than the life of the unhappy Count, was the great object of their solicitude. They now endeavored to obtain a minor grace. They represented that in the Netherlands, and in Germany, there was an important difference in the public mind as to the mode of inflicting the punishment of death upon persons of quality. That decapitation had no influence on the fortunes of the family of the executed, but that the punishment of the wheel was such an infamy, that the uncles, aunts, brothers, and sisters of the criminal, and his whole family, for three succeeding generations, were excluded from all noble chapters, princely abbeys, sovereign bishoprics, and even Teutonic commanderies of the Order of Malta. They showed how this would operate immediately upon the fortunes of a sister of the Count, who was on the point of being received as a canoness into one of the noble chapters.

While this scene was going on in the cabinet of the Regent, the illustrious assemblage of petitioners remained in the hall of council, in the most gloomy state of suspense. The re-entrance from the cabinet of the Cardinal de Rohan and the Marquis de Créqui, with pale, downcast countenances, had struck a chill into every heart. Still they lingered until near midnight, to learn the result of the after application. At length the cabinet conference was at an end. The Regent came forth, and saluted the high personages of the assemblage in a courtly manner. One old lady of quality, Madame de Guyon, whom he had known in his infancy, he kissed on the cheek, calling her his “good aunt.” He made a most ceremonious salutation to the stately Marchioness de Créqui, telling her he was charmed to see her at the Palais Royal; “a compliment very ill-timed,” said the Marchioness, “considering the circumstance which brought me there.” He then conducted the ladies to the door of the second saloon, and there dismissed them, with the most ceremonious politeness.

The application of the Prince de Ligne and the Duke de Havré, for a change of the mode of punishment, had, after much difficulty, been successful. The Regent had promised solemnly to send a letter of commutation to the attorney-general on Holy Monday, the 25th of March, at five o’clock in the morning. According to the same promise, a scaffold would be arranged in the cloister of the Conciergerie, or prison, where the Count would be beheaded on the same morning, immediately after having received absolution. This mitigation of the form of punishment gave but little consolation to the great body of petitioners, who had been anxious for the pardon of the youth: it was looked upon as all-important, however, by the Prince de Ligne, who, as has been before observed,—was exquisitely alive to the dignity of his family.

The Bishop of Bayeux and the Marquis de Créqui visited the unfortunate youth in prison. He had just received the communion in the chapel of the Conciergerie, and was kneeling before the altar, listening to a mass for the dead, which was performed at his request. He protested his innocence of any intention to murder the Jew, but did not deign to allude to the accusation of robbery. He made the bishop and the Marquis promise to see his brother the prince, and inform him of this his dying asseveration.
