The earliest writing can be traced to Sumer, in Mesopotamia. This system did not use an alphabet, instead it used pictographs which are symbols representing familiar objects. This type of writing was called cuneiform, or wedge-shaped writing. Egyptians used hieroglyphics, also a pictograph system.
The Sumerian invention of cuneiformâa Latin term literally meaning âwedge-shapedââ dates to sometime around 3400 B.C. In its most sophisticated form, it consisted of several hundred characters that ancient scribes used to write words or syllables on wet clay tablets with a reed stylus.
