As human societies emerged, the development of writing was driven by pragmatic exigencies such as exchanging information, maintaining financial accounts, codifying laws and recording history. Around the 4th millennium BCE, the complexity of trade and administration in Mesopotamia outgrew human memory, and writing became a more dependable method of recording and presenting transactions in a permanent form.[1] In both Ancient Egypt and Mesoamerica writing may have evolved through calendrics and a political necessity for recording historical and environmental events.
