Týr (pronounced "Teer") is the god of soldiers and of justice, in Norse Mythology. He is the son of the jötunn Hymir and foster son of Odin. He sacrificed his left hand to allow the other gods to seal away Fenrir. Since then he is known as the One-Handed God. The "T"-rune is his sacred symbol: to achive victory in combat one is to "mention Tyr twice" and carve victory runes. This is generally assumed as writing the "T"-rune twice. Týr is one of the many gods invoked at the temple of Uppsala.
