This text is a short paper I submitted to a course at Linköping University:
A formative moment in Norse religion seems to have been the war between the Aesir and Vanir gods. The story is described in both Voluspa and Snorri’s Prose Edda. Voluspa stanzas 22-25 relate “the first war in the world” when the Aesir encounter the Vanir in the form of the magical Gullveig, who is struck with spears, thrice burned and reborn. Odin casts his spear into the Vanir host, who beat down the walls of the Aesir stronghold. Peace is concluded and hostages are exchanged, Njörd, Frey, and Freya to the Aesir, where they become part of the Norse pantheon (while Haenir and Mimir are sent to the Vanir, who cut off Mimir’s head and send it back with Haenir to the Aesir).
