> It's interesting that commerce/business was this sophisticated in the Bronze Age.

That trade would have records is not surprising. That trade would follow patterns based on distance is not surprising, especially since transport costs were very high in that era. Hence the "gravity model".

The surprise here is in organizational form. The article describes a limited partnership contract, with partner investments and a cap table. It's impressive to see that so early. It requires a legal system, or strong social pressure, able to enforce a private contract that complex.

Most early commercial organizations were built around families. Corporations are generally considered to have first appeared in the 1300s, and were rare until the 1700s. I don't think the Roman Empire ever developed the concept of a corporation. Traders, bankers, and merchants existed, of course, but not private organizations larger than one owning family. Although it's hard to tell; not much Roman business info survives.
