An

In Sumerian mythology and later for Assyrians and Babylonians, Anu (see also An) was a sky-god, the god of heaven, lord of constellations, king of gods, spirits and demons, and dwelt in the highest heavenly regions. It was believed that he had the power to judge those who had committed crimes, and that he had created the stars as soldiers to destroy the wicked. He was the father of the Anunnaku (also spelled Anunnaki). In art he was sometimes depicted as a jackal. His attribute was the royal tiara, most times decorated with two pairs of bull horns.

In Hurrian mythology, Anu was the progenitor of all gods. His son Kumarbi bit off his genitals and spat out three deities, one of whom, Teshub, later deposed Kumarbi
