In the Nordic ancient alphabet, the corresponding English letter Z is Ziu.

Ziu is usually considered as a combination of Tyr(T) and Sigel(S).

But its name shows an earlier origin, because Ziu is the earliest name of God Tyr and another variant of Zeus.

The German city of augsburg is the holy land of this god, and its ancient name is Ziusburg.

As a letter representing the gods, Ziu stands for lightning given by the gods.

Therefore, this letter represents the sacred power and energy, and most importantly, the power to pursue justice.

In medieval symbolism, it meant that the past punished the present fairly.
