In 39 AD, Caligula ordered the construction of a massive, temporary pontoon bridge across the Bay of Baiae, a distance of over three miles. He didn't do it to improve commerce, or to expedite a military campaign, but, as the historian Suetonius recorded, to prove a local astrologer named Thrasyllus wrong. Thrasyllus had once declared that Gaius had "no more chance of becoming emperor than of riding a horse dry-shod across the Gulf of Baiae."
Caligula, now emperor, had the entire regional merchant fleet commandeered, linking the ships in a double line, planking them over and covering them with earth. This colossal, unnecessary display of absolute power drew so many vessels that it caused a severe famine in Rome, crippling the very supply lines that fed his people.
When the bridge was complete, the Emperor—dressed in a gold-cloth cloak, sword, and shield—spent two days riding his horse triumphantly back and forth across his self-made land bridge, celebrating a "victory" over the sea itself. He proved his point, but at the cost of his empire's stability.
The American Echo
Now, look at the American landscape. You see the same heedless command of vast resources, not for the people's common good, but for a leader's symbolic victory or personal vanity.
Consider the recent years: the relentless focus on building a massive, symbolic wall along the southern border. This was not a policy debated and designed by experts for maximum efficacy, but a monumental promise fueled by a political leader's insistence, a totem of personal will. The cost in material, manpower, and political capital diverted from actual crises—failing infrastructure, crippling debt, a fragmented society—parallels Caligula's draining of the merchant fleet. The wall became the project, not the purpose.
We have leaders who demand a spectacle, a triumph to be paraded before the masses, regardless of the real-world consequence. Just as Caligula drained the food supply for a vanity bridge, the American state can become consumed by projects of pure political theater, satisfying a leader's psychological need to dominate the narrative while the practical machinery of the Republic grinds to a halt. The absurdity of Caligula's "victory" over the sea finds its modern parallel in the spectacle that political humorists like Jon Stewart and Stephen Colbert dissect nightly—the endless performance that distracts from the tangible decay.
We are watching the precious, finite resources of a colossal empire—be it its wealth, its attention, or its political will—being sacrificed to the whims of its supreme leader's ego. The bridge at Baiae was dismantled; the famine was real. This is the tragic cycle of an empire more concerned with its leader's glory than its citizens' bread.
