Did he(or if we don't know one way or the other could it be assumed?) have had a triumphal procession on his return to Italy, following the battle of Philippi?
I'm also wondering if he had a close friend or subbordinate, a right hand man who would always be at his side?
Lastly, if you have the time, an quick rundown of naming conventions and common names of the time could save me some time, but I'm sure I could find that information some other way so that last one isn't as important as the first two.
His close friend and military commander who won most of his battles was Marcus Agrippa (the same guy who engineered the Pantheon in Rome - not the current version though, even if the inscription remains).
hi! can't help you on the first couple of questions, but there have been lots of questions in this sub about Roman naming conventions. There's a quick intro in this post, which also includes links to several others if you want more detail
How does the Ancient Roman naming system work? It seems very confusing to me...
