Tiewaz is the letter T

Anglo-Saxon Rune Poem (from ragweedforge.com)

Tiewaz is a guiding star; well does it keep faith with princes;
it is ever on its course over the mists of night and never fails

The guiding star that never falters and never fails, the Pole Star, the Nail Star, by which the heavens are held up, and all the other stars move about in eternal circumlocution. It was by the Pole Star that people would find their way at night.
In the Southern US, it was, and is, the Star of Freedom, guiding slaves north, where they could be emancipated. As it is part of Ursa minor, it takes it’s place in mythology of Artemis, for whom the bear was sacred. It is also believed to be part of Hesperides, the daughters of Atlas, who protect the apples of immortality, also with Draco, the Dragon, surrounding them. It was also called Cynosura, The Dog’s Tail, as Ursa minor was also seen as a dog in another myth about these stars.

In Scandinavia it was called Veralder Nagli, (World Spike) which the world was to revolve around, it’s end a glittering jewel which sparkles in the night sky.

It is a symbol of constancy and fixedness, but yet also freedom and guidance. Tiewaz holds it’s own in all things, but by following it one can find their way.
