Raw manpower and sheer genius are underrated nowadays. With the marvels of modern technology, building structures and creating complex technology is an intriguing but commonplace process. Modern builders have the benefit of cranes, heavy excavation equipment and thousands of years of engineering knowledge. Today's technology whizes, while innovative, are largely building off of older technology.
However, thousands of years ago, the engineer had no calculators, no motorized equipment and most of all, he had to do most of the inventing and discovering himself. Despite these seemingly insurmountable odds, ancient engineers created some of the most incredible structures and inventions in the world. Many of these marvels not only still exist today but remain more magnificent than many modern achievements.
