_La Ménagerie de Mme. de Tencin_ was one of the earliest of the eighteenth-century salons, although, in the strict sense of the word, Mme. de Tencin's salon was of a political rather than a literary nature. Successively nun, mistress, mother, she was one of the shrewdest women of the century. Born in 1681, she early became a nun; but such was the character of her life at the convent that it was not long before she became a mother. In 1714 she abandoned her conventual life and went to Paris, where she rose to influence as the mistress of Cardinal Dubois and of the regent, the Duke of Orléans. At Paris her real activity began; she arrived at that gay capital with no other collateral than a pretty face and an extraordinary cunning, which soon brought her a fortune. Fertile in resources of all kinds, she succeeded immediately, and gained for her nephew the cardinal's hat. In 1717 was born to her the afterward famous d'Alembert, whom she left upon the steps of the church Saint-Jean-le-Rond; afterward, when he had become eminent and her power was waning, she unsuccessfully used every means at her command to gain his favor and recognition; the father of that child was the Chevalier Destouches.
About 1726, when lovers were numerous and friends plentiful, the death of Lafresnaye occurred at her salon. In his testament he stated that his death was caused by Mme. de Tencin; however, she was too shrewd, cunning, and careful to be guilty of permitting any weak points to appear in her plots, and it was not difficult for her to clear herself of that charge by the verdict of the judges, who considered the accusation a posthumous vengeance.
The great literary men whom Mme. de Tencin gathered about her, Fontenelle, Montesquieu, Mairan, Marivaux, Helvétius, Marmontel, were called her menagerie, or her _bêtes_. Among them, Marivaux received a pension of one thousand écus from her, besides drawing at will upon the exchequer of an old maid by the name of Saint-Jean. Marmontel, desirous of writing tragedies, took lessons from the famous Mlle. Clairon--at his friend's expense. To give a correct idea of the character of woman's influence upon the literary style of that century, the words of Marmontel may be quoted: "He who wishes to write with precision, energy, and vigor, may live with man only; but he who in his style wishes to have subtleness, amenity, charm, flexibility, will do well, I think, to live with woman."
