In the ancient Mediterranean, letters were often inscribed in clay. If you've ever worked with clay, you'll know that it gets brittle if it gets dry without being fired. It was not meant for long-term storage.

Nevertheless, because of a fire, we have communication with a man named Ea-Nasir, c. 1750 BCE. He collected hundreds of tablets written to him.

They were all complaints. Ea-Nasir was a copper dealer and the first known con artist.

The British Museum has one: https://en.wikipedia.org/wiki/Complaint_tablet_to_Ea-nasir
