I only kno one but in Sumer because they needed to keep trade records they needed a writing system which was invented by the ancient sumerians which was called the cuneiform.

If two books were not allowed in the library at the same time, they would be banned together. If two authors joined together to write a book, it would be said that they banded together.
Sumerian idealogy revolved around the premise of emulating and admiring the deities that they served... Usually the amount of wives was determined by techniques comprised of hydromancy, terramancy, and pyromancy... It was declared that An (high father sky deity) possessed three relationships and others on the side as well... Sumerian law dictated that adultery was permitted and encouraged for men... Also, since there was legal prostitution as part of the sacred ME's of Sumerian civilization (given by Abzu [subterranean water] deity Enki with unfortunate consequences later on), the number of women for sexual satisfaction and child birth could fluctuate in range depending on the level of desire... In short, no real limit, but have the mullah...
Sumerian communities were divided by social structure. There were 3 social classes/or groups. At the top was the upper class. They had the most money and power. In this class there were the priests, kings, government officials, and warriors. They had finer homes. Then came the middle class. There was the artisans, merchants, farmers, and traders. If you needed something they were the ones who had stuff. Normal people lived in small mud-brick houses. Lastly, came the lower class. They were treated harshly. They were considered the enslaved farmers, people forced to work in temples, an slaves. The Sumerian communities were divided into city-states. At the center of each city-state there was a ziggurat. They beleived that the gods lived here. Only gods/godesses were allowed in here.
