Vsp. St. 20: "which yet did not kill her?"

[jgnewman]

Or which killed her each time but didn't force her to stay dead. I like Larrington's interpretation here: "three times they burned her, three times she was reborn, over and over, yet she lives still."

I think "often unseldom" sounds a lot like it's supposed to express the idea of "repeatedly". And "thrice born" does seem to correspond to "thrice burned". Why else be thrice born?

Edit:
You mentioned double-checking Snorri in a TODO. I don't believe the Prose Edda or Heimskringla mention Gullveig at all. Also, thank you for not saying Gullveig is Freyja as I am highly skeptical about this.
