Mesopotamia: I Have Conquered the RiverLiterally "the land between the rivers," Mesopotamia was host to some of the world’s earliest and most powerful civilizations. Shot on location, this program seeks to understand how the Sumerian city-states, cradled by the Tigris and Euphrates Rivers, built a vibrant agricultural economy—and why, after centuries, the wheat crop suddenly failed. Commentary by Asli Ozdogan, of Istanbul University, and Kazuya Maekawa, of Kyoto University; discussion of cuneiform, the Code of Hammurabi, and the Epic of Gilgamesh; and a remarkable 3-D computer re-creation of a peopled street scene offer a glimpse of life in Lower Mesopotamia.
