At what precise date Saint-Germain became an intimate of Louis XV., the Duc de Choiseul, Madame de Pompadour, and the Marechal de Belle-Isle, one cannot ascertain. The writers of memoirs are the vaguest of mortals about dates; only one discerns that Saint-Germain was much about the French Court, and high in the favour of the King, having rooms at Chambord, during the Seven Years' War, and just before the time of the peace negotiations of 1762-1763. The art of compiling false or forged memoirs of that period was widely practised; but the memoirs of Madame du Hausset, who speaks of Saint-Germain, are authentic. She was the widow of a poor man of noble family, and was one of two _femmes de chambre_ of Madame de Pompadour. Her manuscript was written, she explains, by aid of a brief diary which she kept during her term of service. One day M. Senac de Meilhan found Madame de Pompadour's brother, M. de Marigny, about to burn a packet of papers. 'It is the journal,' he said, 'of a _femme de chambre_ of my sister, a good kind woman.' De Meilhan asked for the manuscript, which he later gave to Mr. Crawford, one of the Kilwinning family, in Ayrshire, who later helped in the escape of Louis XVI. and Marie Antoinette to Varennes, where they were captured. With the journal of Madame du Hausset were several letters to Marigny on points of historical anecdote.[45] [Footnote 45: One of these gives Madame de Vieux-Maison as the author of a _roman a clef_, _Secret Memoirs of the Court of Persia_, which contains an early reference to the Man in the Iron Mask (died 1703). The letter-writer avers that D'Argenson, the famous minister of Louis XV., said that the Man in the Iron Mask was really a person _fort peu de chose_, 'of very little account,' and that the Regent d'Orleans was of the same opinion. This corroborates my theory, that the Mask was merely the valet of a Huguenot conspirator, Roux de Marsilly, captured in England, and imprisoned because he was supposed to know some terrible secret--which he knew nothing about. See _The Valet's Tragedy_, Longmans, 1903.] Crawford published the manuscript of Madame du Hausset, which he was given by de Meilhan, and the memoirs are thus from an authentic source. The author says that Louis XV. was always kind to her, but spoke little to her, whereas Madame de Pompadour remarked, 'The King and I trust you so much that we treat you like a cat or a dog, and talk freely before you.'
