RETZ Jean-François-Paul de Gondi, cardinal de (1613-1679) cardinal, archbishop of Paris, opponent of Mazarin and leader of the Fronde; writer and memorialist. L.A.S. "Cardinal de Rets," November 26, 1660, to a cardinal; 2 pages in-4 (small cracks at folds). "If I thanked Your Eminence as often as I am obliged to, I would pester him at every moment of my life. I cannot withhold my gratitude in this case, which makes me see without being surprised all the most essential and effective signs of the friendship of the world which will be eternally the most dear and the most precious to me, and which gives me more true satisfaction and sensitive joy than all the persecutions which I suffer can give me pain. I cannot express to Your Eminence what I am without, and I beg you to believe that it is impossible for me to make her know how much respect, tenderness and recognition I have and will have for the rest of my life, Monseigneur de Vre Emince's most humble, obedient and most obliged servant.
