Here is a great historical series on the wars between Roman and Carthage. They happened a couple hundred years before the time of Christ. They give a feeling for the culture of Rome and I think it also gives some context for understanding the Gospels. Rome had control of Israel during the time of Christ. The Jews wanted to be free of Rome and this is the politics that surrounded Jesus and was the backdrop of his crucifixion. Anyway, if nothing else the series is very entertaining.
