The Man in the Iron Mask

From 1669 until his death in 1703, a prisoner was held in French prisons with his face always covered by a mask (probably velvet, not iron). His identity was kept secret even from jailers. Theories include Louis XIV's twin brother, a disgraced general, or a man who knew too much.
