Shamash

Shamash (Akkadian: šamaš), also known as Utu (written ; Sumerian: dutu, literally "Sun"), was the ancient Mesopotamian sun god. He was believed to see everything that happened in the world every day, and was therefore responsible for justice and protection of travelers. As a divine judge, he could be associated with the underworld. Additionally, he could serve as the god of divination, typically alongside the weather god Adad. While he was universally regarded as one of the primary gods, he was particularly venerated in Sippar and Larsa. The moon god Nanna (Sin) and his wife Ningal were regarded as his parents, while his twin sister was Inanna (Ishtar). Occasionally other goddesses, such as Manzat and Pinikir, could be regarded as his sisters too. The dawn goddess Aya (Sherida) was his wife, and multiple texts describe their daily reunions taking place on a mountain where the sun was believed to set. Among their children were Kittum, the personification of truth, dream deities such as Mamu, as well as the god Ishum. Utu's name could be used to write the names of many foreign solar deities logographically. The connection between him and the Hurrian solar god Shimige is particularly well attested, and the latter could be associated with Aya as well.

While no myths focusing on Utu are known, he often appears as an ally of other figures in both Sumerian and Akkadian compositions. According to narratives about Dumuzi's death, he helped protect him when the galla demons tried to drag him to the underworld. In various versions of the Epic of Gilgamesh and in earlier Gilgamesh myths, he helps this hero defeat the monstrous Humbaba. In the myth Inanna and An, he helps his sister acquire the temple Eanna. In How Grain Came to Sumer, he is invoked to advise Ninazu and Ninmada.
