Well that had to be the fairy tales from the Black Forest of Germany...ALL of them...I could not get enough of that, daytime too! Then 40 years later I learned about archetypes, and the archetypal quality of many fairy tales.
Oh, and when I had read the red fairy book, the green blue yellow etc. fairy books, then I expanded into fairy stories of other countries, definitely to include Hans Christian Andersen and THE LITTLE MATCH GIRL that so impressed Tink!
Still somewhat fascinated, too. A few years ago, a friend introduced me to the tale of the Undines, from where you learn it was the Undines (or Ondines) on which HC Andersen based this take of The Little Mermaid.
