It is difficult to wade through all of the foundation-myth surrounding the founding of Rome. But assuming that The Kingdom of Rome was founded by a man named Romulus and that he was descended from people from (if not Troy, then) somewhere other than Latium, what other possible locations in or around Europe would it be possible for him and his followers to settle and found Rome and what are the affects?
Rome in Germania, Rome in Gaul, Rome in Greece, Rome in Britain?
I've never seen anything exactly like this brought up and thought I'd get some thoughts.
