In "Sigrdrífumál", Sigurd rides to the mountain Hindarfjall, where he sees a wall of shields that surround a sleeping woman. The woman is wearing armor that seems to have grown into her skin, and Sigurd uses his sword to cut it open. This awakens the maiden, who explains that she is the valkyrie Sigrdrífa and, in a prose interlude, tells how she had disobeyed Odin who then demanded she marry. She refused and said she would only marry a man without fear. She proceeds to teach Sigurd wisdom and the runes.
