Besides what you’ve been told about Ea-Nasir already, there’s some extra info:

• Ea-Nasir was a prolific trader. Documents about him have been recovered that were dated years apart because he was a hustler working the grind.
• There’s multiple complaints about Ea-Nasir recorded on different cuneiform tablets, and we recovered almost all of them from one room in one dig site, which we’re pretty sure was his home. During a period when writing was a skilled trade and tablets were a commodity good with some value, and homes were almost all very small, Ea-Nasir dedicated a room in his house to complaints from swindled customers. Apparently to enjoy rereading them because if he cared about improving his goods he would’ve done so at any point.
