Three weeks to build a wall eleven miles long and 12 feet high. President Trump, please take note.
I dont think Caesar had to worry about environmental impact reports or unions or labor laws. You order 10,000 men to build a wall with the incentive that if you get hurt or tired your body will be ground up for mortar then you can accomplish a lot in a short time.
Caesar didnt have the GOPe Congress and Paul Ryan to deal with.
