These graphic novels have little brief histories of the fairy tale in the back, and this one says that in the oldest known written version of Beauty and the Beast, a novel by the french author Gabrielle de Villeneuve, the beast doesn't change back into a prince at the end of the story. Which makes me want to know then - how does it end?? I could find a few articles online talking about some of the other differences between Villeneuve's novel and later versions, such as the convoluted backstories she gave both the Beast and Beauty involving evil fairies, but I couldn't find one that talked about the ending.

(The original text is undoubtedly in the public domain, but am I motivated enough to find a translation? ... Maybe after the holidays.)
