The author has led field expeditions for both U. Penn and the British Museum so his credentials are solid. I wish he had been taught to write in the active voice, however, so his interesting narrative was easier to read. But I digress. Sumaria is considered the first great human civilization, established at around 3500 BC. Archeologists have discovered great temples, stele, weapons, written trade records, law codes, and epics like the Gilgamesh legend from which a lot of much later Old Testament stories derive. The depth of time here is astounding. This great human treasure had been totally forgotten and the existence of the civilization was only discovered within the last century. As I read this book, however, I reflected on the archeology of neo lithic cities like Jericho (maybe 10,000 BC) and Catal Huyuk in Turkey (8000 BC). Clearly mankind has been developing political and cultural societies for a long time since we were hunter gathers. In any case, this book is fascinating, describing the culture, religion, and military exploits of a little known people. Their language is not Semitic and we don’t know where they came from, although the predispositions to put their gods on high places, like ziggurats, suggest they may have come from a mountainous region. Cities like Ur are found at least 100 miles inland from the mouth of the Euphrates/Tigris of today, showing how the land between the rivers has been formed by silting. The land was very fertile which probably led to agricultural development, but it also lacked stone, trees and metal. This led to a need for trade and the Sumerians had trade colonies in Anatolia, the Levant, and the Zagaros mountains. Trade led to writing, roadways, and a strong army, in short, the basis for the first true states. This area was fought over extensively by Akkadians, Hittites, Meads, Assyrians and you name it. As Semitic peoples moved into the rich area of civilization, they adopted the writing and institutions of Ur and other Sumerian cities, and eventually extinguished them, but not their culture. After about 1500 years the Sumerians were gone, replaced by Amorites, Babylonians and more. But think of it. We consider Babylon to be ancient history, yet the Sumerians beat them by 2000 years.
