Tyr, often spelled as "Týr" or "Tyr," is an ancient Norse god in Norse mythology. He is considered one of the principal deities in the Norse pantheon. Tyr is associated with courage, law, and justice, and he is often depicted as a one-handed god. The most famous story involving Tyr is his role in the binding of the monstrous wolf Fenrir. According to the myth, the gods of Asgard had taken in the wolf Fenrir as a pup, but as he grew larger and stronger, they became fearful of his potential danger. They attempted to bind Fenrir with chains, but he broke them easily. Finally, the dwarves of Svartálfaheimr forged a magically unbreakable chain called Gleipnir. The gods approached Fenrir once more, asking him to try breaking the new chain as a test of his strength. Sensing deceit, Fenrir agreed, but only if one of the gods would place their hand in his mouth as a pledge of good faith. Tyr, known for his bravery, stepped forward and put his hand into Fenrir's mouth. When Fenrir realized he could not break the chain, he bit down on Tyr's hand, severing it. Despite his sacrifice, Tyr is often considered a symbol of self-sacrifice, honor, and the fulfillment of duties even in the face of great danger. He played an important role in Norse mythology, but over time, as the influence of other gods like Odin grew, Tyr's prominence diminished.
