On her arrival in Paris, Marie de Medicis at once proceeded to the palace of the Luxembourg, which she had recently built, and embellished with those treasures of art which had rendered it one of the most regal residences in the kingdom. During the first three days of her sojourn there, the gates were closed, and no visitors were admitted; but on the fourth, the King, who had taken up his abode at Versailles, arrived, accompanied by the Cardinal, and followed by all the great nobles, to welcome her back to Paris. Louis had no sooner saluted his mother than he remarked the absence of the Duc d'Orléans, and on expressing his surprise that the Prince had not hastened to meet him, he was informed that his Highness was indisposed. As he was about to despatch one of his retinue with a message of condolence, Gaston was suddenly announced; who, after having paid his respects to their Majesties, stepped back to receive the compliments of the courtiers. At this moment he was accosted by the Cardinal, but before the latter had time to utter a syllable, Monsieur abruptly turned his back upon him, and entered into conversation with the nobles who stood near. Enraged by this public affront, Richelieu immediately approached the Queen-mother, and bitterly complained of the insult to which he had been subjected; but Marie, in her turn, answered coldly: "Monsieur has merely treated you as you deserve." A retort which only served to embitter the indignation of the minister, who at once perceived that, in order to save himself from ruin, he must forthwith possess himself of the ear of the King, and strike a decisive blow. The moment was a favourable one, as intelligence shortly afterwards reached the Court that a treaty of peace with Italy on the most advantageous terms for France had been concluded, and all was consequently joy and gratulation throughout the capital. Showers of rockets ascended from the palaces of the Louvre, the Luxembourg, and St. Germain, which to the faction of Richelieu celebrated the triumph of his exploits beyond the Alps, while to that of the Queen-mother they indicated the downfall of the Cardinal, which it was anticipated would succeed the cessation of hostilities. So convinced indeed was Marie de Medicis that her time of trial was at length over that she disdained to conceal her exultation; and as the first-fruits of her presumed victory she determined to dismiss from her service alike Richelieu himself, who had been appointed superintendent of her household, and every member of his family who was about her person.
