The Rites of Odin by Ed Fitch published in 1990 through Llewellyn says that Tyr is "the invincible warrior of the Nordic pantheon, and far older than all the others of Asgard." He is said to have sacrificed his right hand to help bind Fenrir, the wolf who, when set free, is destined to devour the Sun. It is thought by scholars that he may have been the original father-god of the archaic Indo-Europeans, long before the dawn of our histories."

Norse Mythology by Arthur Cotterell, originally published in 1997 and updated for 1999 by Lorenz Books has this to say: "Tyr, also known as Tiwaz, was the Germanic war god... He was closely associated with Odin and like that god, received sacrifices of hanged men. It is not unlikely that Tyr was an early sky god whose powers were later passed on to Odin and Thor. Gungnir, Odin's magic spear, may once have belonged to Tyr, since it was customary for the Vikings to cast a spear over the heads of an enemy as a sacrifice before fighting commenced in earnest, and over recent years archaeologists have found numerous splendidly ornamented spears dedicated to Tyr."

In Futhark: A Handbook of Rune Magic by Edred Thorrson, originally published in 1984 (using the 6th printing 1991) through Samuel Weiser, Inc. it states:

Esoteric interpretation of the name Tyr - "the sky god".

Phonetic value - 't'.

The T-rune embodies the force ruled by the god Tyr. Tyr is the Norse god of law and justice, who governs proceedings at the thing (the Germanic general assembly). The Tyr force is one of passive regulation. In northern mythology it is this god who comes closest to a transcendental quality. These characteristics are exemplified by the major Tyr myth in which the god sacrifices his hand ("active abilities") between the jaws of the Fenris wolf in order to save his fellow AEsir from destruction. Thus tiwaz is the rune of self-sacrifice and of kings and great leaders of the people.

The word tiwaz, tyr in Old Norse, is the exact cognate to Sanskrit dayus, Greek Zeus and Latin Jupiter. A threefold mystery is contained in tiwaz: (1) justice, (2) war and (3) world column. Certain aspects of all three concepts are intimately related in the runic cosmology.

Smith, Michael  He is forming a runic t with his body...going so far as to lower his head, to round off the top of the t...AND is standing on top of this chair which forms a runic m. "In this pose, Smith is making the sign of Tyr (the Sky God), who (according to Norse mythology) sacrificed his hand to the Fenris Wolf in order to save others. It is also a warrior symbol of great courage, and of overcoming death. He is standing on an M, which is the rune for Mankind. I don't see that as sinister but make of it what you will."  http://themurkynews.blogspot.com/2008/03/wolves-in-sheeps-clothing-research.html
