Invention of writing
In cities, and for hundreds of years, merchants kept records of what they sold as the items they traded. To keep track of sales they covered the chips with mud that they scraped off with the end of a cane. Around 3300 BC, they realized that they did not need figures and began to scratch with simplified signs on whatever surface represented the articles - that was the beginning of writing. As the canes left marks in the shape of a triangle or wedge, this type of writing is known as "cuneiform".
