Tyr (Old Norse: Týr) is one of the battle-gods of Norse mythology, according to the main sources on the topic, the literary works called the Eddas. He takes part in two adventures, one involving a monster to whom he sacrifices his hand, and one where he joins Thor to retrieve a cauldron. His name, related to Zeus or Jupiter, evokes a greater significance at some point in history, but unfortunately, we lack enough historical evidence to confirm it.
