The Decline of Rome

Picture a wall of brick and stone climbing nearly 40 feet into the sky — about as tall as a four-story building — wrapping twelve miles around the city of Rome. I have stood beside what survives of it, and even in ruins it rises far over your head. Emperor Aurelian raised that wall to keep foreign armies out, and Honorius later built it higher still. But the deadliest wall in the Roman world was never made of stone. It was made of words. To keep its own leaders from fleeing, the Roman government wrote 192 separate laws into a single chapter of its law code — 192 ways to trap a man inside his own town.
