Santa = Odin

You’d think the sleigh and the punishing people would give it away.

Why show him aged?

Well, there are plenty of stories about fear turning people’s hair white.
Odin returned from the dead with hidden wisdom, missing an eye.

He was the male form of the Crone archetype.

alternate name, The Allfather. Which fits Santa better.

Quick post but we really should establish this fact.
If only to piss off the re-writers of history.
