She was the daughter of Jean de Lou, sieur de l'Orme, president of the treasurers of France in
Champagne, and of Marie Chastelain. She was born in a wealthy family at her father's château near
Champaubert. Initiated into the philosophy of physical pleasures by the epicurean and atheist
Jacques Vallée, Sieur Des Barreaux, she soon left him for
Henri Coiffier de Ruzé, Marquis of Cinq-Mars, at that time at the height of his popularity, and succeeded, it is said, in marrying him in secret. She began hosting a
salon, and was introduced into the life of being a courtesan. From this time Marion Delorme's
salon became one of the most brilliant centres of elegant
Parisian society. After the execution of Cinq-Mars, she is said to have numbered among her lovers and benefactors
Charles de Saint-Évremond (1610–1703) the wit and litterateur,
George Villiers, 2nd Duke of Buckingham,
Louis, Grand Condé, and even
Cardinal Richelieu. Under the
Fronde her
salon became a meeting place for the disaffected, and
Mazarin is said to have sent officials to arrest her when she suddenly died. The cause of her death, and whether she actually did die then, or rather later, is still debated. == Legend ==
