Notwithstanding all this influence and power, the record of her last years is a sorrowful one. More than ever queen, she was no longer loved by the king, who went to Passy to continue his liaison with a young girl, the daughter of a lawyer. When Louis XV. as much as recognized a son by this woman, Mme. de Pompadour became deeply concerned; but the king was too much a slave to her domination to replace her, so she retained favor and confidence; the following letter shows that she enjoyed little else:
"The more I advance in years, my dear brother, the more philosophical are my reflections. I am quite sure that you will think the same. Except the happiness of being with the king, who assuredly consoles me in everything, the rest is only a tissue of wickedness, of platitudes, of all the miseries to which poor human beings are liable. A fine matter for reflection (especially for anyone born as meditative as I)!..." Later on, she wrote: "Everywhere where there are human beings, my dear brother, you will find falseness and all the vices of which they are capable. To live alone would be too tiresome, thus we must endure them with their defects and appear not to see them."
She realized that the king kept her only out of charity and for fear of taking up any energetic resolution. Her greatest disappointment was the utter failure of her political plans and aspirations, which came to naught by the Treaty of Paris. There was absolutely no glory left for her, and chagrin gradually consumed her. Her health had been delicate from youth; consumption was fast making inroads and undermining her constitution, and the numerous miscarriages of her early years as mistress contributed to her physical ruin. For years she had kept herself up by artificial means, and had hidden her loss of flesh and fading beauty by all sorts of dress contrivances, rouges, and powders. She died in 1764, at the age of forty-two.
Writers differ as to the true nature of Mme. de Pompadour, some saying that she was bereft of all feeling, a callous, hard-hearted monster; others maintain that she was tender-hearted and sympathetic. However, the majority agree as to her possession of many of the essential qualifications of an able minister of state, as well as great aptitude for carrying on diplomatic negotiations.
