Jeanne D'arc is the women who chase the english out of France in the Middle Age. This is the lone women in French women to became a knight but she was burned alive for sorcelery because she said she eard God's voice. So this is not realy a myth (not at 100%) but nice picture.
If you want to translate a name... Her name is Jeanne d'Arc. Joan The Ark comes from a strange habit of translating names... And here a failure as Joan isn't for Jeanne but Johan, Jane is indeed the English version of Jeanne. But let's face it...translating name is the most stupid thing to do.
