Rudolf Simek states that "as the Idisi are supposed to have an influence in the outcome of a battle, similarities with the valkyries suggest themselves. Idisiaviso would thus be a place at which the Idisi had once been instrumental in a battle."[1]
Several etymologies of Iðavöllr (a location in Norse mythology) have been proposed, and the meaning of the name is considered unclear. If Iðavöllr is emended to *Ið[is]avöllr, the location name corresponds precisely to Idisiaviso.[1]
