Týr is the god of single combat, victory and heroic glory in Norse mythology, portrayed as a one-handed man. Corresponding names in other Germanic languages are Gothic Teiws, Old English Tīw and Old High German Ziu and Cyo, all from Proto-Germanic *Tîwaz (*Tē₂waz). The latinised name is Tius or Tio.
In the late Icelandic Eddas, Tyr is portrayed, alternately, as the son of Odin (Prose Edda) or of Hymir (Poetic Edda), while the origins of his name and his possible relationship to Tuisto (see Tacitus' Germania) suggest he was once considered the father of the gods and head of the pantheon, since his name is ultimately cognate to that of *Dyeus (cf. Dyaus), the reconstructed chief deity in Indo-European religion. It is assumed that Tîwaz was overtaken in popularity and in authority by both Odin and Thor at some point during the Migration Age, as Odin shares his role as God of war.
Tyr, known for his great wisdom and courage, agreed, and the other gods bound the wolf. After Fenrir had been bound by the gods, he struggled to try to break the rope. When the gods saw that Fenrir was bound they all rejoiced, except Tyr, who had his right hand bitten off by the wolf.
