Anzû, also known as dZû and Imdugud (Sumerian: 𒀭𒅎𒂂 AN.IM.DUGUDMUŠEN), is a lesser divinity or monster in several Mesopotamian religions. He was conceived by the pure waters of the Apsu and the wide Earth, or as son of Siris.[1] Anzû was depicted as a massive bird who can breathe fire and water, although Anzû is alternately depicted as a lion-headed eagle.
