Utu is the sun god of the Sumerians whom occupied a land north west of Irihia called Ur. His father was Uru te Ngangana (Nanana Lord of the Moon and time), and his mother is Ninga (Hine Turama), daughter of Taane te Wairoa and Hine Hauone.
It is said that Utu was borne from the tourch of the night and the lady of dreams. The twin sister of Utu is Inananga. She is both the morning and evening star otherwise known as Koopuu (Venus) whilst Utu is the sun.
Utu is the power in the light that reveals all that is to be seen and he is the foe of darkness and deeds of darkness. He is also associated with justice and equity, law and order and is the provider of clarity for oracles; also being Lord of the realms of science and astrology. The social role of Utu is therefore as guardian of justice, as judge of gods and men. In such position, he presides in the morning courts, where demons and other evil doers are sued by their human victims. At night Utu judges disputes among the dead of the underworld. He is the last appeal of the wronged, who can obtain no justice from their fellow men, and their cry of despair to him, (I – Utu), was feared as possessing supernatural power.
