Now on a time as they fare abroad in the wood for the getting of wealth, they find a certain house, and two men with great gold rings asleep therein: now these twain were spell-bound skin-changers, (1) and wolf-skins were hanging up over them in the house; and every tenth day might they come out of those skins; and they were kings' sons: so Sigmund and Sinfjofli do the wolf-skins on them, and then might they nowise come out of them, though forsooth the same nature went with them as heretofore; they howled as wolves howl, but both knew the meaning of that howling; they lay out in the wild-wood, and each went his way; and a word they made betwixt them, that they should risk the onset of seven men, but no more, and that he who was first to be set on should howl in wolfish wise: "Let us not depart from this," says Sigmund, "for thou art young and over-bold, and men will deem the quarry good, when they take thee." Now each goes his way, and when they were parted, Sigmund meets certain men, and gives forth a wolf's howl; and when Sinfjotli heard it, he went straightway thereto, and slew them all, and once more they parted. But ere Sinfjotli has fared long through the woods, eleven men meet him, and he wrought in such wise that he slew them all, and was awearied therewith, and crawls under an oak, and there takes his rest. Then came Sigmund thither, and said-- "Why didst thou not call on me?" Sinfjotli said, "I was loth to call for thy help for the slaying of eleven men." Then Sigmund rushed at him so hard that he staggered and fell, and Sigmund bit him in the throat. Now that day they might not come out of their wolf-skins: but Sigmund lays the other on his back, and bears him home to the house, and cursed the wolf-gears and gave them to the trolls. Now on a day he saw where two weasels went, and how that one bit the other in the throat, and then ran straightway into the thicket, and took up a leaf and laid it on the wound, and thereon his fellow sprang up quite and clean whole; so Sigmund went out and saw a raven flying with a blade of that same herb to him; so he took it and drew it over Sinfjotli's hurt, and he straightway sprang up as whole as though he had never been hurt. Thereafter they went home to their earth-house, and abode there till the time came for them to put off the wolf-shapes; then they burnt them up with fire, and prayed that no more hurt might come to any one from them; but in that uncouth guise they wrought many famous deeds in the kingdom and lordship of King Siggeir.
