Imagine precisely cutting and then moving a 120 ton boulder more than two miles without mechanical cutting tolls, skid loaders, or hydraulic cranes. Imagine carving a stone figure that includes a drainage system that permits rainwater to flow through the statue's head to protect the carving from water damage. Imagine designing and building 3,500 steps that extend 100 feet below the surface of the earth with no mechanical equipment. It's amazing to consider the man-made engineering marvels of the Ancient World. Now the question is: how did they do it?
