I would want to be a legionary or just any free Roman Citizen during the 2nd Punic War. I consider this or the time of Augustus when Rome was at its best. When the Romans faced Hannibal and he defeated them at the battle of cannae, Hannibal sent someone to neogotiate Rome's surrender, the Senate however refused to even see him. This is Rome at its greatest time, they had the gift of being able to just put there heads down and fight it out. To see Rome at its best, fighting (in my opinion) the greatest commander in all of history Hannibal. That is when and who I would want to be in Rome.
