Louis-Henri de Pardaillan de GONDRIN (1620-1674) prelate, archbishop of Sens, uncle of Mme de Montespan. L.A.S., Sens 19 March 1649, to Cardinal Mazarin; 2 pages in-4, addressed with red wax seals (broken). He thanks Mazarin for his letter "which shows me that she wants to prevent my very humble services by favors which can only come from her extreme generosity which will always be much more appreciated by your Eminence Monseigneur than the advantages she can give me. Thus she must do me the honor of believing that my fidelity will be in all times"... He puts himself at her entire service and awaits her orders with passion...
