You should be very proud of this film. Well done. One very minor detail - the film you chose for the acquaduct shows it running water down a valley and then up the other side, it being covered. I think that the Romans did not do this and simply ran the water downhill in open chanels. I am still so impressed by this film - don' t let this detail bother you.
I never knew the abacus was invented by the Romans! And they did pipe water and get it to run uphill. They understood the concept of increasing pressure by this method.
You are correct. First off it's the venue, not the entertainment itself. Secondly people have been entertained since the we evolved the laugh. Oh and Greek theater...
