Mythological version of the origin of the Runes.
According to Norse mythology, the runes opened to Odin when, having pierced himself with a spear, he hung on the World Tree for nine days and nights without food and drink. Then, having quenched his thirst with holy (shaman) honey from his grandfather Bölthorn, he heard the runes and scribbled the first of them with a spear on the Tree with his blood.
