Egyptians
The Egyptians invented and used many simple machines, such as the ramp to aid construction processes. The Indus Valley Civilization, situated in a resource-rich area, is notable for its early application of city planning and sanitation technologies. Ancient India was also at the forefront of seafaring technology—a panel found at Mohenjodaro depicts a sailing craft. Indian construction and architecture, called 'Vaastu Shastra', suggests a thorough understanding of materials engineering, hydrology, and sanitation.
