Eleanor of Aquitaine is the most famous woman of the Middle Ages: queen of France and England, crusader, mother of kings — ‘lionhearted’ Richard and ‘bad’ John — and ancestress to the royal dynasties of Europe. Yet more nonsense has been written about her than almost any other woman. Much of what we think we know is falsehood or half-truth, and many respected historians fall foul of her myth, endlessly repeating misinformation as fact.
