From Wikipedia, the free encyclopedia:

In Etruscan mythology, Tinia or Tina was the highest god of the skies, husband to Thalna or Uni. He was part of the powerful triumvirate of gods, including Menrva and Uni. He was associated with lightning, spears and scepters. In Etruscan, tin- means "day." With Uni, he was the father of Hercle.

Tinia was the equivalent of the Roman Jupiter and the Greek Zeus.
