Marduk was a late-generation god from ancient Mesopotamia and patron deity of the city of Babylon. When Babylon became the political center of the Euphrates valley in the time of Hammurabi, Marduk slowly started to rise to the position of the head of the Babylonian pantheon, a position he fully acquired by the second half of the second millennium BC. In the city of Babylon, Marduk was worshipped in the temple Esagila. Marduk is associated with the divine weapon Imhullu. His symbolic animal and servant, whom Marduk once vanquished, is the dragon Mušḫuššu. "Marduk" is the Babylonian form of his name.
