What I already know about the Romans and what I want to find out. 18.4.2020

What I already know:

Julias Ceaser had something to do with the Romans. Romans had bronze coins. The eventually fell apart. On their helmets they had red mohawk looking decorations. When they went to war, they brought fruit cakes with them. The also had square shields which they used by blocking any attacks in a formation. They got took over by the Persian Empire. They also had bath houses.

What I would like to find out:

Did Julias Ceaser create the salad? Was feta made there? Did they farm olives? Did they use spears or daggers. How often did they go to the bathhouse? What professions did they have?
