Which Sumerian god was associated with the sky and authority?

The god associated with the sky and authority in Sumerian mythology is Anu. Anu is recognized as the supreme deity in the Sumerian pantheon and is often depicted as the god of the heavens. His role encompasses not only the sky but also encompasses kingship and authority over other gods and humanity. This signifies his high status and control over the universe, which aligns with the concept of authority in the societal structure of ancient Sumer.

In contrast, Enki is primarily known as the god of wisdom, water, and creation, while Enlil is associated with wind and often regarded as the god who governs the earth and has powerful, if sometimes unpredictable, authority. Ninhursaga, on the other hand, is celebrated as a mother goddess associated with fertility and the earth rather than the sky and authority. Thus, Anu’s unique position as the god of the sky and overall authority underscores why he is the correct answer.
