Alternative historical interpretations of Joan of Arc

There are a number of revisionist theories about Joan of Arc which contradict the established account of her life. These include the theory that she was in fact guilty of the heresy for which she was condemned; that bones and other alleged relics come from her; that she escaped death at the stake and lived out her life in secret.
The following interpretations are sometimes advanced to the public but have not gained significant acceptance among academic historians.
For avowedly fictional representations of Joan in art, literature, and popular culture see Cultural depictions of Joan of Arc.
Royal bastard.
In 1819, Pierre Caze published "La Vérité sur Jeanne d'Arc", which argued that Joan of Arc was the illegitimate daughter of the Queen, Isabeau of Bavaria, and Duke Louis of Orléans. According to Caze's reasoning, the queen hid their daughter in the countryside with the d'Arc family. When Joan of Arc met the future King Charles VII she would have given him a private sign that she was his half-sister. It has been theorized that the coat of arms he later granted her included a sword as a baton of bastardy.
Although this would provide an explanation for how she gained the trust of Charles VII in early 1429, this hypothesis has too many other difficulties to be taken seriously. Foremost among them is that the duke of Orleans died on November 23, 1407. Isabeau of Bavaria delivered a son on November 10, 1407. The likelihood of conceiving a daughter in the interim is exceedingly small. Assuming Joan of Arc was born the following year, she would have been 23 years old at her trial in 1431. She estimated her own age at 19 and all but one of the 115 witnesses at the trial of rehabilitation concurred with that age.
Furthermore, if the sword in Joan of Arc's coat of arms represented a baton of bastardy, then it would be unique in heraldry; it is inconsistent with the laws of heraldry that a sword "party per pale" (see "Coat of Arms of Jeanne d'Arc") be considered a sign of illegitimacy. It would also mean that Joan of Arc and several witnesses perjured themselves about her birth. In the words of Regine Pernoud and Marie-Veronique Clin, "Yet amateur historians still insist that all these people – as well as Charles VII, the duke of Alençon, Dunois, Bertrand de Poulengy – carried out an intricate plot to disguise Joan's authentic royal parents. This thesis lacks credible documentation."
Survival.
Several impostors claimed to be Joan of Arc after the execution date. The most successful was Jeanne (or Claude) des Armoises. Claude des Armoises married the knight Robert des Armoises and claimed to be Joan of Arc in 1436. She gained the support of Joan of Arc's brothers. She carried on the charade until 1440, gaining gifts and subsidies. One chronicle states, "In this year there came a young girl who said she was the Maid of France and played her role so well that many were duped by her, and especially the greatest nobles." Claude finally confessed she was a fraud after Charles VII asked her to repeat the secret which the real Joan had revealed to him when they first met at Chinon in March 1429, which Claude could not do.
Some modern authors attempt to revive this claim by asserting that some other victim was substituted for Joan of Arc at the stake. The likelihood of this is extremely thin, since the trial of nullification records sworn testimony from numerous witnesses who were present at the execution and confirmed her identity.
Dr. Cobham Brewer wrote in his nineteenth century volume "Brewer's Dictionary of Phrase and Fable":
The revisionist theory described by Brewer has been criticized on a number of grounds, including the significant number of eyewitnesses to Joan's execution, as well as the fact that Claude des Armoises subsequently confessed before a number of witnesses on multiple occasions to being an impostor.
Graeme Donald argues that much of the story of Joan of Arc is a myth. He says there are no accounts or portraits of Joan of Arc's victories during her time period, nor is she mentioned as a commander of the French army by Chastellain. He also states that the most definitive work of her life was written by Jules Quicherat between 1841 and 1849, after he discovered a cache of documents relating to her trial. Donald argues that she was most likely not burned. Historians have contradicted this view by pointing out that there is a wealth of information about Joan of Arc's campaigns and life from her contemporaries, including eyewitness accounts of the battles which frequently mention Joan's presence. Many of these were written during the campaigns themselves, such as Guy de Laval's letter on 8 June 1429.
Witch.
In 1921, anthropologist Margaret Murray argued that Joan was correctly identified as a witch by the religious authorities who condemned her to death, but that what they called witchcraft was, in fact, a survival of the pagan "old religion" of pre-Christian Europe. She claimed that Joan and Gilles de Rais were leaders of a pagan witch-cult that was a rival to the Catholic church. Joan was the "incarnate God" of a cult derived from the worship of the virgin huntress Diana. Murray claimed that this was still the religion of most of the common people and the reason Joan inspired the ordinary soldier:
According to Murray, the destruction of Joan was orchestrated by the Catholic Church itself and was its first major victory against the surviving pagan cult:
Murray's views have been dismissed by later scholars as pseudo-historical fantasy. One historian called her ideas "vapid balderdash". Her claims about Joan of Arc were dismissed by historians based on the extensive evidence of Joan's actual religious views, such as the letters she dictated in which she defines her faith in "King Jesus, King of Heaven and of all the earth, my rightful and sovereign Lord." and the many eyewitness accounts of her beliefs and behaviour.
Relics and sites.
The Joan of Arc museum at Chinon, France has a charred bone fragment reputed to belong to Joan of Arc. Its authenticity is unconfirmed and appears to be unlikely, given the circumstances of her death. Indeed, forensic analysis has indicated that the bone is actually from an Egyptian mummy. The English ordered her body burned to ashes and the ashes cast into the River Seine. The Metropolitan Museum of Art in New York City has a helmet in its Arms and Armor collection with a legendary attribution to Joan of Arc. The museum makes no claims that this legend is true, but notes that the helmet dates from the right time period.
Several locations associated with Joan of Arc still exist, including the house where she was born, at Domrémy-la-Pucelle. The site has been converted to a museum. The adjacent church has undergone extensive alterations since the fifteenth century but still contains a fourteenth-century statue of Saint Margaret, before which Joan of Arc probably prayed. By contrast, the royal castle at Chinon is now a ruin. Little more than the outer wall remains. One wall remains of the great hall where she met Charles VII.
