The Sumerians were a people of unknown linguistic affinity, who lived in the southern part of Mesopotamia (Iraq), and whose civilization was absorbed by the Semitic Babylonians around 2000 BC. Babylonian culture reached its peak in about 575 BC, under Nebuchadnezzar, but most of the mathematical achievements we shall discuss in this chapter and in Chapter 5 are much older, going back as far as 2000 BC — about the time when the biblical patriarch Abraham was said to have been born in the Sumerian city of Ur.
