Sun god of Heaven
The Sun god of Heaven was a Hittite solar deity. He was the second-most worshipped solar deity of the Hittites, after the Sun goddess of Arinna. The Sun god of Heaven was identified with the Hurrian solar deity, Šimige.
From the time of Tudḫaliya III, the Sun god of Heaven was the protector of the Hittite king, indicated by a winged solar disc on the royal seals, and was the god of the kingdom par excellence. From the time of Suppiluliuma I, the Sun god of Heaven played an important role as the foremost oath god in interstate treaties.
As a result of the influence of the Mesopotamian Sun god Šamaš, the Sun god of Heaven also gained an important role as the god of law, legality, and truth.
