Illustration by Zinglogo. The origins of the wheel can be traced back to Lower Mesopotamia, where the Sumerians developed rotating axles and wooden discs in the 4th millennium BC. A few centuries later, these discs evolved into lighter, hollowed-out wheels. This revolutionary technology propelled progress in transportation, the wheel being incorporated into carts, battle chariots, and agriculture.
