Utu

In Sumerian mythology, Utu is the offspring of Nanna and Ningal and is the god of the sun and of justice. At the end of every day he descends to the underworld where he determines the fate of the dead. There is no indication of how the jurisdiction of Utu and Nanna differed. Some texts suggest that he sleeps during this time as well.
