Fenrir, likewise called Fenrisúlfr, monstrous wolf of Norse mythology. He was the boy of the demoniac god Loki and a giantess, Angerboda. Fearing Fenrir’s strength and knowing that just evil could be anticipated of him, the gods bound him with a magical chain made of the noise of a feline’s steps, the beard of a woman, the breath of fish, and other occult aspects. When the chain was positioned upon him, Fenrir bit off the hand of the god Tyr. He was gagged with a sword and was destined to lie bound to a rock till the Ragnarök (End Ofthe World), when he will break his bonds and fall upon the gods. According to one variation of the myth, Fenrir will feast on the sun, and in the Ragnarök he will fight versus the chief god Odin and swallow him. Odin’s kid Vidar will avenge his dad, stabbing the wolf to the heart according to one account and tearing his jaws asunder according to another. Fenrir figures prominently in Icelandic and norwegian poetry of the 10th and 11th centuries, and the poets speak apprehensively of the day when he will break out.
