Born at Montmirail, of Italian descent, and much given to intrigue, obtained the coadjutorship of the archbishopric of Paris, plotted against Mazarin, played an important part in the troubles of the Fronde, and was in 1652 thrown into prison, from which he escaped; he left "Memoirs" which are valuable as a record of the times, though the readers are puzzled to construe from them the character of the author (1614-1679).
