Focusing on Genesis 2-4, the early Biblical chapters that are seen as being most incongruous with modern mainline science, Dr. Isham proposes a new historical context for these chapters, one that fits better with the latest findings of Mesopotamian archeology. Ancient Sumerian language and mythology are explored in some depth to arrive at this context. Dr. Isham maintains that Eden can be located in the events leading up to the founding of Ubaidian culture, the first completely civilized society on planet earth. This culture replaced a previous settlement in southern Mesopotamia known variously as Ir-Kalla, Dunnu, or Kur. It was a matriarchal society, and Dr. Isham locates it at the sacred precinct of Kullab in the later Sumerian city of Erech. To the east was the sacred precinct of E-Anna, where Dr. Isham believes the Garden of Eden once stood.
