 When Saxo describes Lagertha as "flying round" () to the rear of the enemy, he ascribes to her the power of flight, according to Jesch, indicating a kinship with the valkyries.The tale notably recalls that of Kára, the valkyrie lover of Helgi Haddingjaskati, who flies above Helgi in battle as a swan, casting spells in his support.Davidson deems it possible, as Nora K. Chadwick considered very probable, that Lagertha is identical with Thorgerd (Þorgerðr Hölgabrúðr), a goddess reflected in several stories.
