As far as the care of the education of her children is concerned, with its sacrifice and real application to duty, she was sometimes called--and not unadvisedly--the type of the ideal mother. From 1757 on her ideas and thoughts ran to education. Her friends were all of the philosophical trend, and intellectual labor was their chief pleasure. After having passed through a career of excitement and love's caprices, she longed for a peaceful, quiet existence; at that point, however, her health gave way, and she entered upon a new territory at Geneva. There she conquered Voltaire, who was profuse with his compliments and kindnesses. Upon her return she became the recognized leader or champion of the philosophic and foreign group and the Encyclopædists, and was regarded as the central figure of the philosophical movement in general. The ideas of the philosophers had been gaining ground, and were disseminated through all classes. The mere love of pleasure and luxury at first found under Louis XV. gave way to more serious reflections when society was confronted with those all-important questions which finally culminated in the Revolution. The salon of Mme. d'Epinay grew to be the most important and, intellectually, the most brilliant of the time. Rousseau, Diderot, Helvétius, Duclos, Suard, the Abbés Galiani, Raynal, the Florentine physician Gatti, Comte de Schomberg, Chevalier de Chastellux, Saint-Lambert, Marquis de Croixmare, the different ambassadors, counts and princes, were frequent visitors In this brilliant circle her letters from Voltaire, read aloud, were always eagerly awaited. Such dramas as Voltaire's _Tancred_, Diderot's _Le Père de Famille_, were given under her patronage and discussed in her salon; after the performance she entertained all the friends at supper.
