 The "Idisi" mentioned in the incantation are generally considered to be valkyries.Rudolf Simek says that "these Idisi are obviously a kind of valkyrie, as these also have the power to hamper enemies in Norse mythology" and points to a connection with the valkyrie name (Old Norse "army-fetter").Hilda R. Davidson compares the incantation to the Old English charm and theorises a similar role for them both.
