Could such a society rival one with that has?

However, if ranked these appearances do not place Teotihuacan ahead of any one of Sumer’s Mesopotamian city-states.

It was here that the political power of religious leaders and the organization of what might have been an early, and strictly relative group of “intellectuals” centralized. Situated between the Tigris and Euphrates Rivers, Sumerian cities such as Uruk grew from small villages to populations of nearly 50,000. In 2600 B.C.E., around the time of Gilgamesh, Sumer had a population of 500,00 people with almost 4/5 of them in urban areas. (45, 54.)

Priests in Sumerian cities built enormous temples called ziggurats. Within these huge stepped “cities wi...
