What 𒑏 means
One ban₂ marks capacity, not a count of things. Cuneiform bookkeeping set it between the everyday sila₃ measure and the larger barig; a tablet from the city of Umma lists ban₂ amounts of fine and common beer.
The ban₂ sign grew with the script: cuneiform writing is first attested in southern Mesopotamia in the Uruk IV period, circa 3500–3200 BCE. A later curved counterpart could mean one-half of the aš counting unit.
