Svipdagr

"[2] In order to accomplish this seemingly impossible task, he summons by necromancy the shade of his dead mother, Gróa, a völva who also appears in the Prose Edda, to cast nine spells for him.

At the beginning of the second poem, Svipdagr arrives at Menglöð's castle, where he is interrogated in a game of riddles by the watchman, from whom he conceals his true name (identifying himself as Vindkald(r) "Wind-Cold" apparently hoping to pass himself off as a frost giant[3]).

On his revealing his identity, the gates of the castle open and Menglöð rises to greet her expected lover, welcoming him "back" to her.

In his children's book Our Fathers' Godsaga, the Swedish scholar Viktor Rydberg identifies Svipdagr with Freyja's husband Óðr/Óttar.

Other scholars who have commented on these poems in detail include Hjalmar Falk (1893), B. Sijmons and Hugo Gering (1903), Olive Bray (1908), Henry Bellows (1923), Otto Höfler (1952), Lee M. Hollander (1962), Lotte Motz (1975), Einar Ólafur Sveinsson (1975), Carolyne Larrington (1999), and John McKinnell (2005).
