573 years ago today Joan of Arc was burnt at the stake in Rouen, France. Her story is quite fascinating if you haven't read it in depth. There are multiple good books you can find, but for pure historical value read, "Joan of Arc: In Her Own Words," and for entertainment value read "Joan of Arc" by Mark Twain.
"Jean d'Arc, sans sepulchre et sans portrait, toi qui savais que le tombeau des heros est le coeur des vivants."
-Inscription on her memorial in Rouen.
(trans: Joan of Arc, without tomb and without portrait, you who knew that the grave of heroes is the heart of the living.)
