The Man in the Iron Mask was a mysterious historical figure solely known for being arrested on unknown charges in France circa 1669. He was imprisoned until his death, and his identity has been a mystery for more more than three centuries. Nobody knew who he was since he had to wear a mask. A professor at the University of California claims he finally uncovered his real identity.
Professor Paul Sonnino from the University of California at Santa Barbara has published a book about the real identity of the masked man. He conducted extensive research and reached a surprising conclusion.
The mysterious man was arrested in 1669, after which he was kept in several French prisons, including the notorious Bastille. He died in 1703, after spending more than three decades in confinement.
According to Professor Sonnino, most historians agree that the man's real name was Eustache Dauger. However, according to research, the mask he wore was made of black velvet and not iron at all.
French philosopher and writer Voltaire speculated that the masked prisoner was King Louis XIV's illegitimate older brother. The Three Musketeers' writer Alexander Dumas presented the prisoner as the King's identical twin.
