In Sumerian mythology, Anu (also An; from Sumerian *An 𒀭 = sky, heaven) 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. His attribute was the royal tiara. His attendant and minister of state was the god Ilabrat.
He was one of the oldest gods in the Sumerian pantheon and part of a triad including Enlil (god of the air) and Enki (god of water). He was called Anu by the later Akkadiansin Babylonian culture. By virtue of being the first figure in a triad consisting of Anu, Enlil, and Enki (also known as Ea), Anu came to be regarded as the father and at first, king of the gods. Anu is so prominently associated with the E-anna temple in the city of Uruk (biblical Erech) in southern Babylonia that there are good reasons for believing this place to be the original seat of the Anu cult. If this is correct, then the goddess Inanna (or Ishtar) of Uruk may at one time have been his consort.
In Sumerian mythology, Ninsar (from Nin = Lady, Sar = Green(ery)) is the goddess of plants.
Also known as Ninki (Lady Earth), Ninmah, Ninmu, Nin-shar
