Egads! A rib bone said to have belonged to Joan of Arc is actually from an Egyptian mummy! To add insult to injury (or something like that) another bone also purported to be from The Maid of Orleans is in reality a cat's femur! The bones were said to have been found among the ashes after Joan was burned to death in the town of Rouen in 1431! Turns out they are actually much older. Around 7th - 3rd Century BC! So unless Joan was one of those wandering spirits who it's said seemed to show up in many different eras, the bones ain't hers.
Someone may have instigated this ungainly deception in the 1800's when Joan was being considered for sainthood. He was cantonized in 1921, by the way. JUst a few years later Danish director Carl Theodore Dreyer made an incredible film about her trial called THE PASSION OF JOAN OF ARC! The film is made up mostly of close-ups of the actors and the woman who plays Joan (her name escapes me right now) gives an amazing performence. Some think it's the greatest single film performence of all time!
So make no bones about! The people who believed really made a boner!
