En dagskjarr Dúrnis niðja salvörðuðr Sveigði vétti, þá er í stein enn stórgeði Dusla konr ept dvergi hljóp, ok salr bjartr þeira Sökmímis jötunbyggðr við jöfri gein.A second online presentation of YnglingatalBy Diurnir's elfin race, Who haunt the cliffs and shun day's face, The valiant Swegde was deceived, The elf's false words the king believed.
