In short: Before humans wrote down stories, they rolled images onto clay to track their wealth. New research reveals a direct lineage between these early accounting tools and the first signs of writing, while ancient myths describe the fierce expansion of the city-state of Uruk.

The transition from pre-literate symbols to actual writing was not a sudden spark of inspiration but a gradual evolution of accounting. In Mesopotamia, specifically the city of Uruk, cylinder seals were invented between c. 4400 and 3400 BC. These were engraved cylinders rolled across wet clay to leave distinct motifs. For centuries, they served as a pre-literate system to track the movement of agricultural products and textiles, essentially acting as the world's first 'signatures' for inventory.

Recent research by a team from the University of Bologna and other institutions has identified a direct continuity between these seals and proto-cuneiform signs, which first appeared in southern Iraq between c. 3350 and 3000 BC. By comparing motifs from before the invention of writing to later signs, researchers found that specific images—such as those representing jars and cloth—transformed directly into the first written symbols. This suggests that the visual language of trade and temple-managed commodities provided the blueprint for the first writing systems.

While writing eventually allowed for complex narratives, its origins were rooted in the practicalities of the fourth millennium BC. This era was defined by the rise of Uruk as a regional powerhouse. One of the most famous accounts of Uruk's expansion is the Siege of Aratta. According to Sumerian mythology, the ruler Enmerkar led an army through the Zagros Mountains to conquer the wealthy, isolated civilization of Aratta. This legendary conflict, involving the pursuit of gold and lapis lazuli, reflects the real-world expansion of Uruk's influence across modern-day Iran and Türkiye.
