Jakob and Wilhelm Grimm collected a lot of stories, not just the dozen or so that are best known. This is one of them, and it's fairly harrowing. It doesn't take much - any - elaboration to see "Fitcher's Bird" as a story of rape and domestic violence. What's more, it posits these things as horrible crimes that merit and will ultimately bring forth a severe punishment. Which doesn't sound like much, except... The story has its origiins in a time when women were considered the property of their husbands.
So I wonder. Is this a case of the folk tale acting as a kind of folk conscience? And how many more such cases are there?
