High Quality Content by WIKIPEDIA articles! The characteristics of ancient Egyptians are indicated by a set of artifacts and customs that lasted for thousands of years. The Egyptians invented and used many basic machines, such as the ramp and the lever, to aid construction processes. They used rope trusses to stiffen the beam of ships. Egyptian paper, made from papyrus, and pottery were mass produced and exported throughout the Mediterranean basin. The wheel, however, did not arrive until foreign invaders introduced the chariot in the 16th century BC. The Egyptians also played an important role in developing Mediterranean maritime technology including ships and lighthouses.
