Speaking of Óðr, I’ve encountered some interesting theories about him in my studies recently.
Most scholars tend to view him as a strange double or Vanic counterpart of Óðinn associated with creative and battle frenzy, shapeshifting, shamanic ordeals and otherworldly journeys.
However a number of Neopagan authors apparently regard him as the God of the Summer Sun, and specifically heat, vitality, fertility and rejuvenation, with his absence in Winter prompting Freyja to go in search of him.
Something about that really resonates, although I’m not sure their arguments necessarily hold up to scrutiny. Then again, so little has come down in the lore concerning Óðr that most arguments end up being fairly speculative, mine included. (This is where being an Orpheotelest and mantis really comes in handy.)
