Anu is a prominent figure in ancient Mesopotamian mythology, often regarded as the god of the sky. He is considered one of the oldest deities in the Sumerian pantheon and is associated with authority and kingship. Anu's role was crucial in maintaining order in the universe, and he was believed to oversee the heavens and the celestial bodies. In many myths, Anu is depicted as a powerful and distant god, often residing in the highest heavens. He is the father of other important gods, such as Enlil and Ea, who play significant roles in creation and governance. Anu's influence extended to the earthly realm, where kings sought his favor to legitimize their rule.
