TYR GOD OF WAR, LAW AND JUSTICE. Pronounced "Tier". (Old Norse) Tyr, (Old English) Tiw, in modern English "Tuesday" from Old English "Day of Tiw". The Rune Tiwaz is associated with Tyr, it represents the letter "T" and it is the arrow symbol that is used today to indicate "direction". Vikings would sometimes paint the Tiwaz rune on their shields and pray to Tyr along with Thor and Odin for victory. In the mythology of The Binding of Fenrir, Tyr was the only one who would place their hand in the fearsome beast's mouth as a show of good faith and only then would Fenrir allow the gods to bind him. When Fenrir could not break free, he took Tyr's hand. Thus Tyr proved himself to be the god of Justice by sacrificing his hand in order to uphold justice. Just as Odin sacrificed one of his eyes in the pursuit of wisdom. In the above image Tyr is portrayed sailing ashore the Vigrid plain at Ragnarok with Fenrir closing in.
