The earliest writing can be traced to Sumer, in Mesopotamia. This system did not use an alphabet, instead it used pictographs which are symbols representing familiar objects. This type of writing was called cuneiform, or wedge-shaped writing. Egyptians used hieroglyphics, also a pictograph system.
Cuneiform is a system of writing first developed by the ancient Sumerians of Mesopotamia c. 3500-3000 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 advanced the writing of cuneiform c. 3200 BCE.y the middle of the Third Millennium B.C., cuneiform primarily written on clay tablets was used for a vast array of economic, religious, political, literary, and scholarly documents. The great literary works of Mesopotamia such as the famous Epic of Gilgamesh were all written in cuneiform.
