 In the prose introduction to the poem Sigrdrífumál , the hero Sigurd rides up to <unk> and heads south towards " the land of the Franks " . On the mountain Sigurd sees a great light , " as if fire were burning , which blazed up to the sky " . Sigurd approaches it , and there he sees a <unk> with a banner flying overhead . Sigurd enters the <unk> , and sees a warrior lying there — asleep and fully armed . Sigurd removes the helmet of the warrior , and sees the face of a woman . The woman 's corslet is so tight that it seems to have grown into the woman 's body . Sigurd uses his sword Gram to cut the corslet , starting from the neck of the corslet downwards , he continues cutting down her sleeves , and takes the corslet off of her .
