People originally invented a type of sled known as a "light pry," which allowed them to slide across the ground using a sliding rod. However, it was challenging to haul these sleds on barren hills with limited roads. One day, during a strong wind, they noticed that smooth stones or logs rolled faster than other objects under the wind's force. This observation sparked a brilliant idea. Using stone axes, people began cutting logs into shorter pieces and creating a circular hole at both ends. They then inserted thinner wooden sticks into these holes to connect the logs. As a result, they successfully manufactured roller sleds that were much lighter to drag compared to the earlier sleds. This innovation, known as roller sleds, emerged around 2000 BC.
However, when people tried using these rollers to transport heavier items, they would often fracture. To address this issue, individuals started using copper or iron hoops along the wheels. Legend has it that wheels with spokes were used in Central Asia around 3000 BC. Surprisingly, Egypt, a highly developed civilization at the time, was unaware of this technology and continued to use log wheels for hauling goods. It was only in 1600 BC, when the Hyksos invaded Egypt with horse-drawn chariots, that the Egyptians discovered the advantages of wheeled vehicles. They started reinforcing the wheels with spokes and rims, but these were still made of wood. Eventually, with the arrival of steel, wooden wheels evolved into steel wheels, and the addition of rubber tires filled with air further enhanced their efficiency. Over time, wheels became more and more advanced, reaching a state of perfection.
While there may be disagreements among archaeologists, there are some points that they do agree on. It's important to take a closer look at these areas of consensus to gain a better understanding of the subject matter.
The use of the wheel for creating pottery can be traced back to ancient times. It was an essential tool used to create containers that served as the earliest form of human craftsmanship. The primary function of this wheel was to allow potters to produce pottery in batches. The simplest form of the potter's wheel consists of a pair of disc-shaped wheels. The potter rotates the lower wheel with their feet while placing soft clay on the upper wheel with their hands. They would then shape the clay into various forms. This process has remained largely unchanged throughout history and is still used today by potters all around the world.
In ancient Mesopotamia, the first wheels were basic round plates securely fastened to the shaft. As time progressed around 3000 BC, the carts began to feature attached axles, separating the wheels from the body. Subsequently, the innovation of spoked wheels emerged. Although these early wheelbarrows were somewhat unwieldy, they marked a significant improvement compared to the conventional methods of relying on human shoulders or pack animals, predominantly donkeys, which had been utilized in the past.
Throughout history, wheels have played a crucial role in the design of combat vehicles. Initially, these chariots were used to quickly charge into enemy lines and disrupt their formations. Later on, they were transformed into combat platforms, allowing soldiers to stand on them and hurl weapons, such as javelins and crossbows, at their adversaries with deadly precision. In this way, the strategic use of wheels helped to turn the tide of many battles and shape the outcome of countless conflicts.
