 MacLeod and Mees believe the word means something like "supernatural sending", and that this points to a connection to the Ragnhild Tregagás charm, where a valkyrie is also "sent forth".The Old Norse poems "Völuspá", "Grímnismál", "Darraðarljóð" and the "Nafnaþulur" section of the "Prose Edda" book "Skáldskaparmál", provide lists of valkyrie names.In addition, some valkyrie names appear solely outside of these lists, such as "Sigrún" (who is attested in the poems "Helgakviða Hundingsbana I" and "Helgakviða Hundingsbana II").
