Hanging from a tree, being impaled to a tree, whatever. Norse mythology says Odin sacrificed himself to himself, god to god, to gain the power of the runes...and Jesus sacrificed himself so he could give us power to repent...and both hung for the sake of the continuation of the world, Odin's sacrifice for the runes to ward off the Ragnarok as long as he could.

Are you asking if he hanged, as if he had a noose around his neck? Or as if he was impaled onto a cross? Don't quote me on this, but I've read the original was written in aramaic and the exact thought of whether he hung on a cross or a tree is disputed...whatever.
