There's an interesting article by Micah Hanks at Mysterious Universe, about research into the ancient roots of folktales. The example given is the story known as "The Smith and the Devil," which - according to researchers - has been traced back as far as the Bronze Age, and may be as much as 6000 years old. (The illustration shown was for a version from Norway published by Peter Christen Asbjornsen.)

Hanks also links to an earlier article which I found even more interesting, about a widespread but also very specific folkloric association between showers of rain when the sun is shining, and foxes' weddings - and also supernatural lights associated with foxes:
