As mistress, her duties were many: to manipulate and manage Versailles, please and captivate the king, make allies, win over the highest officials and keep control of them, put her own friends in office, attach to her favor every man of prominence,--princes and ministers,--keep in touch with the court, appease, humor, and win the honor of the courtiers, "attach consciences, recompense capitulations, organize about the mistress an emulation of devotion and servility by means of prodigality of the favors of the king and the money of the state; but what was a more burdensome task,--she must occupy the king, aid and agitate him, fight off constantly, from day to day and hour to hour, ennui."
This terrible ennui, indifference, enervation, this lazy and splenetic humor of the king, she succeeded in distracting, in soothing, and amusing. She understood him perfectly--therein lie the great secret of the favor of Mme. de Pompadour and the great reason of her long domination which only death could end. She had the patience and genius to soothe the many ills of the monarch, possessing an intuitive understanding of his moral temperament, and a complete comprehension of his nervous sensibility; these gifts were a science with her and enabled her to keep alive his taste for and enjoyment of life. Mme. de Pompadour is said to have taken possession of the very existence of Louis XV.
"She appropriates and kills his time, robs him of the monotony of hours, draws him through a thousand pastimes in this eternity of ennui between morning and night, never abandoning him for a minute, not permitting him to fall back upon himself. She takes him away from work, disputes him to the ministers, hides him from the ambassadors. In his face must not be seen a cloud or the slightest trace of care of affairs; to Maurepas, in the act of reading some reports to the king, she says: 'Come now, M. de Maurepas, you turn the king yellow.... Adieu, M. de Maurepas'; and Maurepas gone, she takes the king, she smiles upon the lover, she cheers the man."
In 1747, two years after her installation, she interested the king in a theatre, and inaugurated the famous representations at the Théâtre des Petits Appartements; she herself was one of its best actresses, singers, and musicians. All the members of the nobility vied with one another in procuring admission to these performances, as auditors or actors. Her contemporaries say that she was without a rival in acting, for in that art she found opportunity to show her vivacity, her _esprit_ of tone, and her malice of expression, the effect of which was heightened by her voice, graceful figure, and tasteful attire, which became the envy of every court lady.
