Writing

The first wheel was made from clay, rock and mud which slowly developed to the making of wheels by joining together of wooden planks. They connected it to vehicles called chariots. It got them to places they wanted to go quickly. It was one of the biggest achievements in history.

The first use of the wheel for transportation was on Mesopotamian chariots in 3200 BC. And the process began with the early men placing rollers beneath heavy objects so that they could be moved easily.

Invention

Wheel

Writing was invented by the Sumerians around 3100 BC. It began as record keeping for trade and evolved into the use of symbols for writing down laws and stories. The form of writing is called cuneiform. Pictograms, or drawings representing actual things, were the basis for cuneiform writing. Early pictograms resembled the objects they represented, but through repeated use over time they began to look simpler, even abstract. These marks eventually became wedge-shaped ("cuneiform"), and could convey sounds or abstract concepts
