"The first day of Odin’s ordeal on the world tree Yggdrasil, leading to the discovery of the runes. According to the Edda, Odin hung on the tree for nine days and nights. This is commemorated from 17 August to 25 August, the final day being the festival of the Discovery of the Runes, when Odin fell “screaming” from the tree, having gained the knowlegde."
I'm assuming that this is NOT an ancient, traditionally celebrated holiday, but rather that this is relatively a recent addition by some select modern-day heathens????
