Sumerian Economy

The economy that sustained the people of Sumer relied on agriculture and trade. To support agriculture, the surrounding land of each city-state was plotted out into individual tracts which were then irrigated through a system of canals and dams. The irrigation of the land allowed for crops such as wheat and barley to flourish in this region. Trade, another important element of the economy, occurred through the transportation of textiles and crops by Sumerian merchants to other lands, such as Asia-Minor and Iran, where these goods were exchanged for stone, metals, and timber. The traders would then return to Sumer where these items would either be traded to other Sumerians or used to fabricate jewelry, tools, and weapons to be traded later.

One of the greatest accomplishments of the Sumerian people was the invention of the earliest known system of writing. The Sumerians created written documents by using a triangular-tipped stylus to make wedge-shaped impressions in soft clay. Because of their appearance, these impressions have been given the name "cuneiform" (from Latin, meaning "wedge-shaped"). Thousands of cuneiform documents have been discovered, the majority of which are record of business, taxation, and production figures. However, many cuneiform documents have been found to be inscribed with epics, myths, essays and poetry, as well as educational texts.

Other skills and innovations that the Sumerians developed include the art of engraving, bleaching and dying of fabrics, the development of measuring and surveying equipments, as well as canals and dams. The Sumerians are also well-known for cylinder seals which have been discovered in archaeological digs. These artifacts depict various scenes of Sumerian life and beliefs. One of the most commonly depicted episodes on these seals was on in which the seal's owner is presented to a god by another god, presumably the owner's "guardian angel." Other cylinder seals were also used to record business transactions.
