The book of lost tales

I'm utterly enchanted by the story that a book of lost fairy tales has been found. A contemporary of Grimm, Franz Xaver von Schönwerth collected five hundred tales by asking folk about their lore, but neglected to publish them. I find this magical, not because an unknown nineteenth-century book has come to light (exciting as that is), but because it might contain unguessed tales many centuries older. Stories from the long, long ago that have lain untold. Stories that walked among our ancestors, once upon a time.
