Around 3200 BC the system evolves into a more systematic form of writing known as cuneiform. Using a blunt-ended stylus, Sumerians imprint wedge-like strokes into a clay tablet.
It took a conventional form of linear cuneiform drawings and was written from left to right. The Sumerians used cuneiform to write their stories. Then the Semitic Akkadians, Babylonians, Assyrians and Canaanites used the sound signs to write down their spoken languages.
Since the time of Christ the knowledge about the Sumerians and their language was totally forgotten and vanished from the history. It was known only after 18000 AD when the cuneiform script was deciphered.
Today, scholars used the cuneiform records to help them understand the way of life and achievements on the Middle East thousands of years ago.
