Cuneiform is a system of writing first developed by the ancient Sumerians of Mesopotamia circa 3600/3500 BCE. It is considered the most significant among the many cultural contributions of the Sumerians and the greatest among those of the Sumerian city of Uruk, which further developed and advanced cuneiform circa 3200 BCE and allowed for the creation of literature.

Pottery made by people of the Halafian culture, who inhabited northern Mesopotamia between around 6200 and 5500 BC, is painted with flowers that have 4, 8, 16 or 32 petals, and some show arrangements of 64 flowers. These patterns show a clear understanding of symmetry and spatial division long before written numbers came into use around 3400 BC, argue scientists in a new study. The skill might have helped the Halafian people with tasks such as sharing harvests or dividing communal fields, the authors say.

The foundation of future Mesopotamian advances in scientific/technological progress was laid by the Sumerians, who first explored the practice of the scientific hypothesis, engaged in technological innovation, created the written word, developed mathematics, astronomy, and astrology, and even fashioned the concept of time itself. Some of the most important inventions of the Sumerians were: the wheel the sail the corbeled arch/true arch irrigation and farming implements maps mathematics time and clocks astronomy and astrology medicinal drugs and surgery
