Readers may not think of technology as being from the ancient world, but advances in agriculture, weaponry, art, and food preparation have influenced the development of both human history and the physical development of humans themselves, as well as human migration all over the world. Using photographs, this book thoroughly examines the earliest human technologies, including irrigation, metal work, and ancient artillery, to show readers just how technologically advanced ancient cultures were and to show how human history began to develop because of each of the advancements.
