I realize that Loki’s mother Laufey and the goddess Iðunn are not obviously connected, but there are parallels between them. These reveal the power and gender politics of Norse myth. In some ways Laufey is an inversion of Iðunn.
Back in the ’90s I wrote a book called Asyniur, which attracted a certain amount of scorn because I named Freyja’s two cats as Bygul and Trjegul. Unfortuantely, this is not ancient lore but comes from a book by Diana Paxson, Brisingamen.
However, I did escape another trap that lies awaiting the newbie – I did not place Iðunn in Breidablik. But I feel the pain of anyone who did. Bragi and Iðunn should have a home of their own. Jack Kirby and Stan Lee obviously agreed with me, and gave them one.
