Can I just add, regarding Grimm.
I was lucky enough to come across the 2 volume, 'Grimm's Household Tales' with the author's' notes, edited and translated by Margaret Hunt (London 1884) - (cost me £12) a world of difference from the either anodyne or sensationalised versions freely available.
Well worth looking out for.
Folk tales are all too often watered down, reduced and produced for children when they were once very much an adult entertainment.
We were fortunate enough to spend many hours (literally) recording some of the last few of the big Irish storytellers, mainly in Clare.
We heard tales lasting well over an hour - we have had described to us a local man who would start his story on Monday night, break it off, continue it the following night, and so on, until Friday.
Malcolm Taylor was kind enough to issue a cassette of our sample of tales recorded in the British Isles and Ireland, (not just ours)
Sadly, it is no longer available, but anybody interested is welcome to a copy via Dropbox.
