Rome Chooses Duration Over EfficiencyRome could kill anyone quickly. It had the sword, and beheading is fast, clean and cheap.Instead it builds crucifixion, which takes hours in public view, and it builds the amphitheatre as an inward-facing pit so that tens of thousands of people watch a death together.If you wanted an execution you would not design either of these. If you wanted a sustained high-volume emission of horror from a crowd, you would design exactly these.
