Týr

Týr (Gothic Teiws, Old English Tīw and Old High German Ziu and Cyo, all from Proto-Germanic *Tīwaz) is a Norse god associated with law, honor, justice and heroic glory in Germanic mythologies. His Latinised name is Tius or Tio, and Tuesday was named "Tīw's Day", as a translation of dies Martis equating him with Mars, the Roman god of war. Speculation exists that he was once considered the father of the gods and head of a pantheon, since his name is ultimately cognate to that of *Dyeus (or Dyaus), the reconstructed chief deity of ancient Indo-European religion.

Quotes

 * Men prayed to Tyr for victory in battle, and justice in peace. He is renown for his wisdom as well as his valor. Tuesday is named in his honor. In some places he was called Tiwaz and was associated with the Roman God, Mars, the Celtic God Nadu [sic], as well as the Indian God, Mitra. Tyr was the original God of war, and the precursor of Odin, much in the same way that Mars was the God of war in Rome, and once held a higher place than Jupiter.

 * Tyr … is a relatively minor Aesir god in Viking Age Norse mythology. However, his name and attributes along with evidence from the study of comparative religion divulge to us that his Viking Age form is a severely diminished version of a divine figure who, in earlier ages, was the highest god of the Norse and other Germanic peoples. (By the Viking Age, this role had been usurped by Odin.)
