Iron Mask for G8M

The Man in the Iron Mask died 19 November 1703 was an unidentified prisoner of state during the reign of King Louis XIV of France (1643–1715). Warranted for arrest on 28 July 1669 under the pseudonym of "Eustache Dauger", he was incarcerated on 24 August and held for 34 years in the custody of the same jailer, Bénigne Dauvergne de Saint-Mars, in four successive French prisons, including the Bastille. When he died there on 19 November 1703, his inhumation certificate bore the pseudonym of "Marchioly", leading several 19th century historians to conclude the prisoner was Italian diplomat Ercole Antonio Mattioli. His true identity remains a mystery, even though it has been extensively debated by historians, and various theories have been expounded in numerous books, articles, poems, plays, and films. Among the oldest theories is one proposed by the French philosopher and writer Voltaire, who claimed in the second edition of his Questions sur l'Encyclopédie (1771) that the prisoner was an older, illegitimate brother of Louis XIV. This assertion of a royal connection was echoed later by authors who proposed variants of this aristocratic solution.
The Man in the Iron Mask has been the subject of many works of fiction, most prominently in 1850 by Alexandre Dumas. A section of his novel The Vicomte of Bragelonne: Ten Years Later—the final installment of his D'Artagnan saga—features this prisoner, portrayed as Louis XIV's identical twin and forced to wear an iron mask. In 1840, Dumas had first presented a review of the popular theories about the prisoner extant in his time in the chapter "L'homme au masque de fer", published in the eighth volume of his non-fiction Crimes Célèbres. This approach was adopted by many subsequent authors, and speculative works have continued to appear on the subject.
