Dr. Steve Tinney, Associate Curator, Babylonian Section, Penn Museum. The great Babylonian myth “When on high …”, often called the Babylonian Epic of Creation, traces the history of Babylon from the very beginning of time itself. Swallowing many other ancient Mesopotamian myths it presents a single story of how Marduk became king of the gods by killing the Sea, and founded Babylon as the center of the universe. As it does so, it reveals much about ancient Mesopotamian cosmos and that most important of institutions, the city.
