The Edda pops in mind, but that’s obvious. Deeper roots are reconstructed by Wagner cum suis, but it is wacky (we brutal conquerers), alike Frazer’s Golden Bow. However, it points to another separate explanation of the origins which have puzzled mankind everywhere anytime. I’m inklined to dig even deeper, the early stone age, maybe from the stepstone dividing beasts from responsibleness, to find our curious dependency of a caring father, a nurturing mother. Why did Ötzi climb the high peaks of the Alps? Survival or Salvation?
