Marduk is a major deity in ancient Mesopotamian mythology, particularly revered in Babylon. He is often depicted as a god of creation, water, and magic, and is associated with the planet Jupiter. Marduk became the chief god of the Babylonian pantheon, especially after the rise of Babylon as a significant city-state. In the famous Enuma Elish, a Babylonian creation myth, Marduk defeats the chaos monster Tiamat and creates the world from her remains. This victory established him as a symbol of order and civilization, and he was worshipped through various temples, including the grand Esagila in Babylon.
