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
Tiewaz signifies, judgement, discernment, integrity, and wisdom. Like the idea of the Pole star, which helps to give direction by night, Tiewaz gives guidance and direction, helping to know right from wrong, helpful from harmful, the need instead of the want. One of the traditional uses of Teiwaz was to be engraved or pressed into weapons on their blade, as a way to bring success and victory in battle. Tiewaz/Tyr was the Germanic god who was equaled with the Greco-Roman Mars/Ares, but unlike that concept of a bloody, battle loving deity, it is my understanding that the Germanic concept of War (and thus their War god) was a means of resolving disputes, and resolving conflict, not always in loss of lives and spilling blood, but in defeating your enemies because truth and the Gods were on your side. Thus placing Tiewaz on their weapons wasn’t about winning in bloody battle, but striking with discernment, as way to demonstrate your integrity and righteousness.
In having the discernment to see what is wrong, and exercising the judgement and wisdom to cut away the harmful, and so perhaps lose something in order to gain greater rewards.
