In 1723, after the death of the Regent, the Duc de Bourbon became Prime Minister of France. His wife, Anne Marie de Bourbon, had died and his mistress, the famous Marquise de Prie, reigned supreme--an even more fascinating, and certainly a more intelligent woman than the Montespans, Pompadours, and Du Barrys, who so completely succeeded in captivating the Bourbon Kings. She possessed a beautiful voice, with which she interpreted Italian music, learnt during her stay in Turin where her husband for many years had been ambassador. She also, like Madame de Pompadour, patronised art and had portraits of herself painted by Rosalba and Vanloo. Her house was furnished with exquisite taste, and she understood to perfection the arts of the toilet. At first she devoted herself to a life of pleasure, but she soon saw the wisdom of becoming her lover's adviser-in-chief. In order to shield him against the intrigues of the Orleans family--as long as the King remained unmarried and without a nearer heir--she persuaded the Prime Minister that the Spanish Infanta, daughter of Philip V, who had been educated at the French Court and was intended to be the future Queen-Consort of France--though she was still a child of not much more than ten years old--should be sent back to her father. When this had been accomplished a marriage was speedily arranged with Maria Leczinska of Poland, although she was several years older than the young King. This act led to an immediate rupture with Spain and brought no political advantage to France. But in order to understand to the full the game played here by Madame de Prie, we should note that Maria Leczinska had been at first intended for Monsieur le Duc; wherefore by making her Queen of France she not only hoped to keep her lover to herself, but also to get ascendancy over the King through a queen whom she had helped to raise to so exalted a position. Somewhat unexpectedly, however, she found an implacable enemy in Cardinal Fleury, who was to Louis XV what Richelieu and Mazarin had been to his predecessors. He had been the young King's preceptor and exercised a great influence over him. When it occurred to Fleury that he might become Prime Minister in place of the Duc de Bourbon the latter, notwithstanding the strenuous efforts of Madame de Prie, was compelled to yield and to resign on the charge that he had confided affairs of State to unqualified persons. He retired to Chantilly with his mistress, where, the lady received a most discourteous welcome from Madame la Duchesse Douarière; and to the grief and dismay of the Duke a _lettre de cachet_ from the King presently commanded her to retire to a property in Normandy which belonged to her long-neglected husband. The Duc de Bourbon never ceased to regret her, because, as he asserted, he felt that she was so devoted to his interests as to have subordinated every other sentiment. She only survived her humiliation a few years; but it was some time after her
