Ancient Egyptians Mastered Sewage and Drainage Systems
When most people think of ancient cities of any kind, they automatically eliminate the luxuries we are used to today. While ancient Egypt certainly didn’t have complex sewage systems that people are accustomed to now, this ancient civilization had already developed an efficient sewage and drainage system that served as evidence of the value they placed on cleanliness. An American urban planner noted the “great importance” that ancient Egyptians placed on cleanliness, especially in a city known as Amarna. “Toilets and sewers were in use to dispose waste,” the planner noted. “Soap was made for washing the body. Perfumer and essences were popular against body odor. A solution of natron was used to keep insects from houses…. Amarna may have been the first planned ‘garden city.’” According to historians, ancient Egyptians were “pretty adept with drainage construction” by 2500 B.C.
East Africans Developed Steel Making more than 1,500 Years Ago
Evidence discovered in 1978 showed that East Africans were making steel for more than 1,500 years: “Assistant Professor of Anthropology Peter Schmidt and Professor of Engineering Donald H. Avery have found as long as 2,000 years ago Africans living on the western shores of Lake Victoria had produced carbon steel in preheated forced draft furnaces, a method that was technologically more sophisticated than any developed in Europe until the mid-nineteenth century.”
