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.
