Sablé, Madeleine de Souvré, marquise de ( 1599-1678). Sablé is best known for the Jansenist salon* over which she presided after her self-sequestration in a home immediately adjacent to Port-Royal* in the late 1650s. More notable salon participants included Nicole, Amauld, Domat, Pascal, La Rochefoucauld, and on occasion Madame de Lafayette*. From their collaborative inquiries on the human condition, the salon developed and nurtured the austere and evocative genre of the maxim. Sabld is herself the author of eighty-one maxims, which were first published posthumously in 1678. She also left in manuscript a collection of maxims entitled De l'amitié. Given the striking similarities between her maxims and those of La Rochefoucauld, there has been much speculation about the extent of Sablé's influence on the celebrated moralist. Literary historians have suggested that the salon may have likewise played an important role in the composition of Pascal Pensées. La Rochefoucauld's letters confirm that Sablé also wrote a treatise, L'Instruction des enfants, when there was some possibility of the Duke's becoming guardian to the Dauphin; it is not extant. Sablé was an active participant at Mme de Rambouillet's* chambre bleue, where she engaged in an affectionate correspondence with the poet Voiture, among others; Chapelain praised her esprit and finesse in letters to Balzac. Sablé's conflict-ridden personal life provided rich fodder for the famed novelist Madeleine de Scudéry*, who painted a detailed verbal portrait of Sablé as "Parthénie" in Le Grand Cyrus. After unsuccessfully protesting her arranged marriage* at the age of fifteen to Philippe-Emmanuel de Laval, marquis de Sablé, she succeeded in separating from him only after his scandalous behavior threatened to ruin both of them. The Marquise's own love affairs, love of good food, and lifelong propensity for hypochondria were often the subject of gossip in the intimate social circles of the salons.
