Note 45 — XII SAINT-GERMAIN THE DEATHLESS

One of these gives Madame de Vieux-Maison as the author of a roman à 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'Orléans 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.
