3 types of writing for life in sumer?

In ancient Sumer, three primary types of writing were used: cuneiform, which was inscribed on clay tablets for administrative and economic purposes; religious texts that documented myths, hymns, and rituals; and literary works, such as the Epic of Gilgamesh, which explored themes of heroism and human experience. Cuneiform evolved from pictographs to more abstract symbols, reflecting the complexity of Sumerian society. These writings were essential for record-keeping, communication, and cultural expression.
