"Everything done, Madame, between the two courts, is absolutely due to your zeal and wisdom. I feel it and cannot refuse myself the satisfaction of telling you and of thanking you for having been my guide up to the present time. I must not even keep you ignorant of the fact that their Imperial Majesties give you the full justice due you and have for you all the sentiments you can desire. What has been done must merit, it seems to me, the approbation of the impartial public and of posterity. But what remains to be done is too great and too worthy of you for you to give up the task of contributing and to leave imperfect a work which cannot fail to make you forever dear to your country. I am, therefore, persuaded that you will continue your attention to an object so important. In this case, I look upon success as certain and I already share, in advance, the glory and satisfaction which must come to you, no one being able to be more sincerely and respectfully attached to you than is your very humble and obedient servant, the Count de Kaunitz-Rietberg." She received her first check when, Damiens having attempted to assassinate the king, the dauphin was regent for eleven days. She was confined to her room and heard nothing from the king, who was in the hands of the clergy. Among the friends who abandoned her was her protégé Machault, the guard of the seals, who conspired with D'Argenson to deprive her of her power and went so far as to order her departure. After the king's recovery, both D'Argenson and Machault were dismissed and Mme. de Pompadour became more powerful than before. Her influence and usurpation of power bore heavily upon every department of state; she appointed all the ministers, made all nominations, managed the foreign policy and politics, directed the army and even arranged the plans of battle. Absolute mistress of the ministry, she satisfied all demands of the Austrian court, a move which brought her the most flattering letter from Kaunitz, in which he gives her the credit for all the transactions between the two courts. Despite all her political duties and intrigues, she found time for art and literature. Not one minute of the day was lost in idleness, every moment being occupied with interviews with artists and men of letters, with the furnishers of her numerous châteaux, architects, designers, engineers, to whom she confided her plans for embellishing Paris. Being herself an accomplished artist, she was able to win the respect and attention of these men. Her correspondence was immense and of every nature, political and personal. She was an incessant reader, or rather student, of books on the most serious questions, which furnished her knowledge of terms of state, precedents of history, ancient and modern law; she was familiar with the contents of works on philosophy, the drama, singing, and music, and with novels of all nations; her library was large and well selected.
