At first glance this verse might seem like it is about witch burning, but on deeper inspection it is not so. Gollveig means something close to "Gold Might." As the symbol of gold she has been burned 3 times, refined, and emerges as the "Bright One" ever living and inspiring magic in women. The connection between Freya and gold as well as magic is strong, but the truth of such a connection is lost to time.

Voluspa - Norse Mythology Book - Verse 21

“The war I remember, the first in the wold,

When the gods with spears had smitten Gollveig,

And in the hall of Hor had burned her,

Three times burned, and three times born,

Oft and again, yet ever she lives.”

Bellows Translation
