School tablet - Sumerian cuneiform - Susa - 2nd mil BC - National Museum of Iran - Inventory number - 1885

One of the earliest specimens of human writing. Not literature, not law — accounting. The need to keep track of grain in a temple bureaucracy is what pushed marks-on-clay into a system that could one day carry epics.

Marks the boundary between proto-writing and writing. We can see signs being used systematically — but not yet phonetically. The leap to recording speech itself comes a few centuries later.

The earliest historical document in human history. Before this, we have lists, accounts, and dedications. Here, for the first time, a ruler tells us what happened — with names, places, and consequences.
