According to Jacobsen, this god was originally envisioned as a huge black thundercloud in the shape of an eagle, and was later depicted with a lion's head to connect it to the roar of thunder. Some depictions of Anzu therefore depict the god alongside goats (which, like thunderclouds, were associated with mountains in the ancient Near East) and leafy boughs. The connection between Anzu and Abu is further reinforced by a statue found in the Tell Asmar Hoard depicting a human figure with large eyes, with an Anzu bird carved on the base.
