Madame de Rambouillet was no admirer of King Louis XIII, and she gratified Tallemant's curiosity with stories of the reigns of Henry IV and Louis XIII that were of real historical value. The society of the Hôtel de Rambouillet opened a field for his acute and somewhat malicious observation. In the Historiettes he gives finished portraits of Vincent Voiture, Jean Louis Guez de Balzac, Malherbe, Jean Chapelain, Valentin Conrart and many others; Blaise Pascal and Jean de la Fontaine appear in his work; and he chronicles the scandals of which Ninon de l'Enclos and Angélique Paulet were centres.
The Historiettes are invaluable for the literary history of the time. It has been said that the malicious intention of Tallemant's work may be partly attributed to his bourgeois extraction and that the slights he received are avenged in his pages, but independent testimony has established the substantial correctness of his statements. In 1685 he was converted to Catholicism. It seems that the change was not entirely disinterested, for Tallemant, who had suffered considerable pecuniary losses, soon after received a pension of 2,000 livres. He died in Paris.
Des Réaux was a poet and contributed to the Guirlande de Julie, but it is by his Historiettes that he is remembered. The work remained in manuscript until it was edited in 1834-6 by MM. de Châteaugiron, Jules Taschereau and LJN de Monmerqué, with a notice on Tallemant by Monmerqué. A third edition (6 vols. 1872) contains a notice by Paulin Paris. Tallemant had begun Mémoires pour la régence d'Anne d'Autriche, but the manuscript has not been found.
