Ancient History

Knowledge and understanding about some of the oldest civilizations and what happened to them can hopefully help us in the current day and age avoid making similar mistakes.   For me personally there is a strong desire to under the why behind the lose of knowledge about some of these oldest cultures; Ancient Egyptian, Mayan, Aztec and Sumerian and key areas where their knowledge and practices intersected:


All these cultures developed stratified societies with classes like elites, commoners, and slaves. The ruling class often held religious authority as well. They built impressive cities that served as centers of administration, religion, and trade. Think of Egyptian Memphis, Mayan Tikal, Aztec Tenochtitlan, and Sumerian Ur.


These civilizations developed advanced mathematical systems for trade, construction, and even calendars. They were observers of the night sky, using it to track time, predict seasons, and even for religious purposes.  Their architectural accomplishments are beyond impressive from Egyptian pyramids to Mayan temples, are testaments to their engineering.  For me mankind an can learn so much from embarrassing the past.
