The Man in the Iron Mask

The story of Man in the Iron Mask is a story that most of us have read or seen portrayed in movies. Fictional accounts of this prisoner of the ‘Sun King’ include a novel by famed author Alexandre Dumas and a movie starring Leonardo DiCaprio. However, the Man in the Iron Mask is no fictional character, even if his imprisonment and identity are shrouded in mystery. He was a real prisoner of Louis XIV, who was imprisoned for at least five years and maybe more than forty. The problem is that no one alive today has any clue who this man was. Furthermore, there has been so much wild speculation, rumors and possible facts as to his identity that historians and history buffs may never be able to sort out who he really was. Nonetheless, there are some facts and speculations that we may go on to form our own opinion.

Facts About the Man in the Iron Mask

It should be pointed out that many of the so-called ‘facts’ about the Man in the Iron Mask are not verifiable. Suffice it to say that the following information is widely regarded as truth. Moreover, this information fits with just about every story about the Man in the Iron Mask, even the least likely of the bunch. However, it is certain that the Man in the Iron Mask was a real person and that he was forced to wear a mask.

The Man in the Iron Mask was a prisoner at Bastille from 1698 until 1703. It is thought by many that he was a prisoner before this and had simply been transferred there. However, there is no proof of this, unless you rely on hearsay.

Whoever he was, the Man in the Iron Mask died on November 19, 1703. A death certificate that is associated with him lists his name as Monsieur de Marchiel. It says that he was in his 40’s at the time of his death.

The Man in the Iron Mask is widely considered to have been royalty. This is based on clues regarding his treatment during his incarceration.

Legends and Rumors About the Man in the Iron Mask

The most popular of all the legends regarding this prisoner pertains to his lineage. It has been said that the Man in the Iron Mask was the twin brother of King Louis XIV. The story goes on to say that the man was kept hidden because of his rights to the throne. Another story says that the prisoner was indeed the king’s brother, but not his twin. This one varies too.

In one version, the prisoner is the king’s older brother and first in line to be king and so, Louis XIV has him imprisoned. Another version says that the prisoner is Louis XIV’s younger brother, but that Louis was the bastard son of the former Queen and one of her lovers. Therefore, the Sun King had no rights to the throne. All of these versions say that the king had his brother imprisoned and masked to hide his identity. Yet another version of this story says that the king’s brother did not die in prison, but that he escaped. After he made good his escape, he went to meet with his co-conspirators. He then rode toward Paris and was killed while en route.
It has been speculated that the prisoner’s mask was not iron at all, but cloth. In addition, he may not have had to wear it all the time, as many accounts suggest. He may have only had to wear it when he was out in public. There are some eyewitness accounts that seem to corroborate these claims.

*The idea that the Man in the Iron Mask was royalty stems from the following information/rumors.

It is said that Princess Palatine had knowledge of the prisoner that she included in a letter. She said that he was treated favorably, but heavily guarded, lest he take off his mask, which he was ordered not to do, under threat of death. She supposedly went on to say that the mask remained on his face always.

Voltaire, who was a prisoner at Bastille in 1717, claimed that he had learned things from former servants of the masked prisoner during his time there. He wrote that the Man in the Iron Mask had been wearing the mask as far back as at least 1661. He also said that he was tall, handsome and played the guitar. He wrote again about him later, saying that he was about 60 at the time of his death. This would have been the only way that he could have been Louis XIV’s twin brother, as the Sun King was in his 60’s when the prisoner died. However, this would mean that the death certificate that is associated with the prisoner is either false or not that of the prisoner.

Joseph LaGrange-Chancel also wrote about the Man in the Iron Mask, after his stay in prison. He was a prisoner on Sainte-Marguerite during the 1720s. He said that the Man in the Iron Mask had stayed there during the mid to late 1600s. Voltaire also made this claim. He went on to say that Saint-Mars (the governor of Sainte-Marguerite and once keeper of the famous prisoner) called the Man in the Iron Mask “my prince.” Of course, this claim is only hearsay. Furthermore, Chancel would have heard this information nearly twenty years after the prisoner had died. There was sufficient time for unfounded rumors to circulate. Then again, it could have very well been true.

Some other speculations regarding the identity of the Man in the Iron Mask include him being the Duc of Beaufort or Antonio Ercole Matthioli. The former man was said to have been the lover of Louis XIV’s mother. He was imprisoned so that no one would learn that the king was a bastard. The latter was an enemy of the king who had been tried for treason. Nevertheless, there, regrettably, remains no proof of any of these claims. With all of the rumors convoluting the story, it is doubtful that we will ever know who the Man in the Iron Mask was.
