Enlil holds possession of the Tablets of Destiny which gives him power over the entire cosmos and the affairs of man. He is sometimes friendly towards mankind, but can also be a stern and even cruel god who punishes man and sends forth disasters, such as the great Flood which wiped out humanity with the exception of Atrahasis. Enlil is portrayed wearing a crown with horns, symbol of his power. His most prestigious temple was in the city Nippur, and he was the patron of that city. His equivalent is the Akkadian god Ellil.
In ancient Sumero-Babylonian myth, Enlil ("lord wind") is the god of air, wind and storms. Enlil is the foremost god of the Mesopotamian pantheon, and is sometimes referred to as Kur-Gal ("great mountain"). In the Sumerian cosmology he was born of the union of An heaven and Ki earth. These he separated, and he carried off the earth as his portion. In later times he supplanted Anu as chief god. His consort is Ninlil with whom he has five children: Nanna, Nerigal, Ningirsu, Ninurta, and Nisaba.
