Fenrir (in. Fenris) – in Scandinavian mythology a huge wolf, one of the three children Loki had with the giant Angerboda. It was characteristic for him that because of its size, during yawning the jaw touched the sky and the mandible touched the ground. Fenrir is mentioned in Poetic Edda and Prose Edda. Both sources regard him as the father of the wolf brothers Sköll and Hati.
The gods were afraid that when the wolf grew up, it could threaten them, so they decided to bind him with a chain called Løding. However, the beast was liberated from it, and also from another, much stronger one, called the Dreads. The dwarfs weave a magical rope called Gleipnir, made of the sound of the cat’s footsteps, the beard of a woman, the root of a rock, the tendons of a bear, the breath of fish and the saliva of a bird. The gods took the wolf to an island, where they were to bind him with a magic rope, but Fenrir, having sensed the trick, decided to agree to bind the Gleipnir on condition that one of the gods put his hand in his mouth. The god Tyr took up this task. But when the gods bound the wolf, Tyr could not free himself, then the angry Fenrir bit off his right hand. From now on Tyr was also called the One-Handed.
Fenrir is to free himself from his ties and devour the god Odin on the day of Ragnarök during the last battle of the gods with the giants. He will be killed by Odin’s son, Widar.
