Nusku
Nusku was the name of the light and fire-god in Babylonia and Assyria, indistinguishable from Girru - formerly Gibil.
Nusku is the symbol of the heavenly as well as of the terrestrial fire. As the former he is the son of Anu, the god of heaven, but he is likewise associated with Enlil of Nippur as the god of the earth and regarded as his first-born son. A centre of his cult in Assyria was in Harran, where, because of the predominance of the moon-cult, he is viewed as the son of the moongod Sin, though Nusku was with Enlil when Sin wasn't born yet, and Enlil hadn't married Ninlil - Sin's mother. Nusku is by the side of Ea, the god of water, the great purifier. It is he, therefore, who is called upon to cleanse the sick and suffering from disease, which, induced by the demons, was looked upon as a species of impurity affecting the body.
The fire-god is also viewed as the patron of the arts and the god of civilization in general, because of the natural association of all human progress with the discovery and use of fire. As among other nations, the fire-god was in the third instance looked upon as the protector of the family. He becomes the mediator between humanity and the gods, since it is through the fire on the altar that the offering is brought into the presence of the gods.
