I didn’t know that the English ordered Jeanne d’Arc’s[1] body to be burned thrice; now, it turns out that some of her remains may have survive lo these many hundreds of years.
[1] There’s some dispute over the Maid of Orleans’ real name; there is some evidence (nothing dispositive) that her name was Jeanne Darc, not Jeanne d’Arc… but “of the Arc” does have a nice ring to it.
