Between Tigris and Euphrates rivers, Sumer's city-states birthed writing, wheels, and urban complexity around 3500 BCE. This book traces Mesopotamian evolution—from Sumerian ziggurats at Uruk and Ur, through Hammurabi's Babylonian law code, to Assyria's iron legions and Nineveh library. Drawing from cuneiform tablets, cylinder seals, and recent Iraqi excavations, Cradle of Civilization: Sumer, Babylon, Assyria reveals administrative genius, flood myths, and astronomical records that shaped Abrahamic traditions. It examines how irrigation kingdoms balanced priestly hierarchies with merchant networks across three millennia.
