The highest god in Mesopotamian religions. In general, An was a god that played little role in myths or cult. He was regarded as a distant force.
In Sumerian religion, An was the god of heaven, and theoretically the highest god. But he also assumes a minor role in the myths, hymns and cult. An's main cult centre was Uruk.
An's name is written as a star, which denotes both heaven and god. His holy city was Erech.
Akkadian, Babylonian and Assyrian religions
In Akkadian, Babylonian and Assyrian religion, An's name became semitificated into Anu.
In Hittite religion, Anu deposed Alalu, who was the first king in heaven. Then there was a war between the god Kumarbi and Anu. Yet it was not Anu, but rather Kumarbi's son, Teshub, the weather god, who overcame Kumarbi.
