Around 2600 BCE, cuneiform writing in Mesopotamia evolved from pictographic symbols to include phonetic elements representing sounds in spoken language. This transformation enabled scribes to record literature, religious texts, and correspondence by using signs to represent syllables and sounds rather than objects alone. The phonetic system expanded cuneiform from an accounting tool to a comprehensive writing system capable of expressing complex narratives and abstract concepts. This development allowed preservation of Mesopotamian myths, epics, and records that survive today.
