Nearly 2,000 years ago, the Roman emperor Gaius assembled a massive invasion force and marched it across Europe to the English Channel. The elite of the greatest army in the world, along with a massive array of siege engines, drew up in battle formation along the shore, awaiting orders. Mounting a platform, Gaius commanded the trumpets to sound and then issued the orders: “Gather shells!” The soldiers frantically scrambled around the beach to fill their helmets with seashells. Gaius then erected a monument to celebrate this “victory against the sea” and transported the “booty” a thousand miles back to Rome for a triumphal march.
Gaius, or Caligula, as he is more commonly known, was crazy. According to Roman chroniclers, this was only one example of his crazy behavior. He also nominated his horse to the consulship, capriciously threw law-abiding citizens into the arena, and depleted the treasury with lavish spending on orgies.
Unfortunately for Rome, Caligula was just the first of many lunatic emperors. Nero, Commodus, and many others would rival him in both lunacy and incompetence. Although the chroniclers probably exaggerated the malfeasance of these emperors, the record of the imperial succession by itself evinces the instability of Rome’s leadership.
