“Mr. de Camp has the trick of being able to show technology engaging in feats as full of derring-do as those of Hannibal’s army. History as it should be told.”—Isaac Asimov, The New York Times Book Review The Pyramids of Giza, the Parthenon of Greece, the Great Wall of China, the Colosseum of Rome. Today, we stand in awe before these wonders of the ancient world. They hold our history and the deepest secrets of our past in their hidden recesses. In The Ancient Engineers, L. Sprague de Camp delves into the heart of the mystery. He introduces us to the master builders who had the vision, the power, and the passion to reach for the clouds and touch the heavens. We share in some of the greatest technological triumphs of all time—triumphs of the human mind, imagination, and spirit.

We live in an age in which one can easily think that our generation has invented and discovered almost everything; but the truth is quite the opposite. Progress cannot be considered as sudden unexpected spurts of individual brains: such a genius, the inventor of everything, has never existed in the history of humanity. What did exist was a limitless procession of experiments made by men who did not waver when faced with defeat, but were inspired by the rare successes that have led to our modern comfortable reality. And that continue to do so with the same enthusiasm. The study of the History of Engineering is valuable for many reasons, not the least of which is the fact that it can help us to understand the genius of the scientists, engineers and craftsmen who existed centuries and millenniums before us; who solved problems using the devices of their era, making machinery and equipment whose concept is of such a surprising modernity that we must rethink our image of the past.

Charles Ortloff provides a new perspective on archaeological studies of the urban and agricultural water supply and distribution systems of the major ancient civilizations of South America, the Middle East, and South-East Asia, by using modern computer analysis methods to extract the true hydraulic/hydrological knowledge base available to these peoples. His many new revelations about the capabilities and innovations of ancient water engineers force us to re-evaluate what was known and practised in the hydraulic sciences in ancient times. Given our current concerns about global warming and its effect on economic stability, it is fascinating to observe how some ancient civilizations successfully coped with major climate change events by devising defensive agricultural survival strategies, while others, which did not innovate, failed to survive.
