Navicularius

A navicularius was a person who worked in the shipping business. They were responsible for owning and managing ships.

During ancient Roman times, navicularii were important members of society. They were responsible for transporting goods and people across the Mediterranean Sea. For example, a navicularius might own a ship that transported olive oil from Italy to Spain.

In modern times, navicularii still exist. They might work for a shipping company, managing the logistics of transporting goods across the world. For example, a navicularius might be responsible for ensuring that a shipment of electronics arrives safely from China to the United States.

These examples illustrate how a navicularius was an important figure in the shipping industry, responsible for managing the transportation of goods and people across the sea.
