Sumer. The irrigated farming together with annual replenishment of soil fertility and the surplus of storable food in temple granaries created by this economy allowed the population of this region to rise to levels never before seen, unlike those found in earlier cultures of shifting cultivators.
This much greater population density in turn created and required an extensive labour force and division of labour with many specialised arts and crafts. At the same time, historic overuse of the irrigated soils led to progressive salinisation, and a Malthusian crisis which led to depopulation of the Sumerian region over time, leading to its progressive eclipse by the Akkadians of middle Mesopotamia. Sumer was also the site of early development of writing, progressing from a stage of proto-writing in the mid 4th millennium BC to writing proper in the 3rd millennium BC (see Jemdet Nasr period). Origin of name[edit] History of Sumer. The history of Sumer, taken to include the prehistoric Ubaid and Uruk periods, spans the 5th to 3rd millennia BC, ending with the downfall of the Third Dynasty of Ur around 2004 BC, followed by a transitional period of Amorite states before the rise of Babylonia in the 18th century BC.
The first settlement in southern Mesopotamia was Eridu. The Sumerians claimed that their civilization had been brought, fully formed, to the city of Eridu by their god Enki or by his advisor (or Abgallu from ab=water, gal=big, lu=man), Adapa U-an (the Oannes of Berossus). The first people at Eridu brought with them the Samarran culture from northern Mesopotamia and are identified with the Ubaid period, but it is not known whether or not these were Sumerians (associated later with the Uruk period).[1]
Sumerian Language Page. The Story of Mathematics - Sumerian/Babylonian Mathematics. Sumer (a region of Mesopotamia, modern-day Iraq) was the birthplace of writing, the wheel, agriculture, the arch, the plow, irrigation and many other innovations, and is often referred to as the Cradle of Civilization.
The Sumerians developed the earliest known writing system - a pictographic writing system known as cuneiform script, using wedge-shaped characters inscribed on baked clay tablets - and this has meant that we actually have more knowledge of ancient Sumerian and Babylonian mathematics than of early Egyptian mathematics. Indeed, we even have what appear to school exercises in arithmetic and geometric problems.
