We all know the story of Joan of Arc. A peasant girl who hears voices from God. A warrior leading an army to victory, in an age that believes women cannot fight. The Maid of Orleans, and the saviour of France. Burned at the stake as a heretic at the age of just nineteen. Five hundred years later, a saint. Her case was heard in court twice over. One trial, in 1431, condemned her; the other, twenty-five years after her death, cleared her name. In the transcripts, we hear first-hand testimony from Joan, her family and her friends: a rare survival from the medieval world. What could be more revealing?
