The Man with the iron mask was a prisoner of Louis XIV whose identity is not known. The man was imprisoned from 1669 until his death in 1703. The man was forced to wear a black cloth over his face most of the time; no one saw his face. The prisoner always had the same guardian. Most of the facts that are known are from correspondence, mostly of his guardian with his superiors. When he was first imprisoned, the identity of the man was given as "Eustache Dauger". He is buried in the graveyard of the church Saint-Paul-Saint-Louis in Paris. His tombstone says his name was "Marchiali". Other sources also give the names "Marchioly", or "Marchialy."
