I remember that when I studied Russian, one of the amusing things about the folk tales we looked at was that they had not been bowdlerised to match Victorian ideas of what was good for children, or Disneyfied to match American ones. Byzantine folk tales seem to have escaped such treatment, too.
Having three death-dealing angels standing in a field of dead enemies is a bit different from “and they all lived happily ever after…”
…oops, hope that wasn’t a spoiler.
All the best,
