La belle et la bête is a pretty old story in France, true-- from the 1700's I believe? But since it's such a simple story it has roots in lots of different places. My favorite old version, which I've actually stolen quite a lot from, is the Cupid and Psyche myth. There's like a million though, from all over the world.
