The ancient writing system used by the Sumerians is known as cuneiform. Developed around 3200 BCE in ancient Mesopotamia, this script was inscribed on clay tablets using a stylus to create wedge-shaped marks. Cuneiform served multiple purposes, including recording transactions, laws, literature, and administrative documents, making it one of the earliest known writing systems. It evolved over the centuries, adapting to different languages and cultures, and became integral to the administration of ancient societies. Cuneiform writing played a crucial role in the documentation of human history, enabling the recording of thoughts and events.
