Latest / Nero: Mad Tyrant or Misunderstood Emperor? — Fexingo History / Nero's Herculean Feat: The Isthmus of Corinth Canal
Transcript
- Lucas: So we've talked about Nero's bridge of boats, his golden house, even his botanical obsessions — but there's one project that tops them all in sheer audacity. I'm talking about his attempt to cut a canal through the Isthmus of Corinth. Luna: Wait, the same isthmus where the modern canal is? Lucas: Exactly. And Nero didn't just dream about it — he actually broke ground with a golden pickaxe in 67 AD. It was a spectacle, an engineering challenge, and pure imperial theater all rolled into one. Lucas: The idea wasn't new. Periander, the tyrant of Corinth, supposedly tried it in the sixth century BC. Alexander the Great considered it, and Julius Caesar had plans too. But nobody actually dug until Nero. And he went in with all the drama you'd expect. Luna: Why was it such a big deal? I mean, why risk all that effort? Lucas: Well, the isthmus is only about six kilometers wide at its narrowest. But sailing around the Peloponnese could take days, and it was notoriously dangerous — storms, pirates, the works. A canal would save a voyage of over 300 kilometers. For Rome, with its grain shipments from Greece and the East, that was a strategic prize. Lucas: But there was also a symbolic angle. Nero saw himself as a new Hercules. And Hercules had actually dug a canal there — well, in myth, he'd supposedly scraped the ground to create the strait of Gibraltar. So by cutting through the isthmus, Nero was literally following in his hero's footsteps. Luna: He really thought of himself as Hercules on earth, didn't he? Lucas: Oh, absolutely. He'd even shaved off his beard for the Greek tour because Alexander had been beardless. But for the canal, he brought out the golden pickaxe, sang hymns to Amphitrite and Poseidon, and gave a rousing speech to the troops. Cassius Dio says he himself struck the first blow. Lucas: The actual work was done by thousands of prisoners — Jewish captives from the war in Judea, plus criminals and soldiers. They were organized into gangs, and there was even a lottery to assign sections to different units, to make it competitive. It was a huge operation. Luna: So how far did they actually get? Lucas: That's the thing — they barely made a dent. They started at both ends, near Lechaion on the Corinthian Gulf and Cenchreae on the Saronic Gulf. But the geology was terrible — hard limestone and clay, and they kept hitting rock that was too tough for their tools. Plus the engineers were, frankly, incompetent. Lucas: Pausanias, who visited later, said the whole project was just a folly. He wrote that the workers had only scratched the surface, and the hills were too high. Even today, the modern canal had to blast through rock that would have been impossible for Roman technology. Luna: So it was never going to work, even with all those men? Lucas: Probably not. They lacked the explosives and the heavy machinery. But Nero didn't care about the engineering feasibility. He was more interested in the propaganda value. He posed for statues with a pickaxe, minted coins showing the canal, and called it 'the work of a god' — or so Suetonius claims. Lucas: And then, in 68 AD, the whole thing came to a halt. Nero had to rush back to Rome to deal with the rebellion of Vindex, and the project was abandoned. The Jewish prisoners were reassigned to other tasks, and the canal stayed a scar in the landscape for centuries. Luna: It's almost poetic — his last big project, just a half-dug ditch. Lucas: Yeah, and there's a darker twist. After Nero's death, Vespasian — who was busy rebuilding Rome — didn't want to be seen as continuing Nero's vanity projects. So he deliberately stopped the work. He even had the tunnel entrances blocked up, to erase the memory. Lucas: The canal wasn't actually completed until 1893, almost 2,000 years later. And even then, it took modern machines and dynamite to cut through that same rock. Luna: Hmm, so in a way, Nero's failure wasn't just bad luck — it was bad geology and bad politics. Lucas: Exactly. And it's fascinating because it shows the gap between imperial ambition and practical reality. Nero could order thousands of men to dig, but he couldn't command the rock to yield. Not even a golden pickaxe could change that. Lucas: But you know, there's a reason we're talking about this today. In a way, Nero's canal is a perfect metaphor for his whole reign — grandiose visions, tremendous resources, but ultimately a failure to deliver. And yet, the vision itself was so compelling that it stuck around for centuries. Luna: People kept trying to finish it, didn't they? Lucas: Oh, yeah. Herodes Atticus, a wealthy Greek, tried in the 2nd century. The Venetians tried in the 15th. But it wasn't until the modern era that they had the technology to actually do it. So Nero's dream, as impractical as it was, was the first real attempt. Lucas: If you've been enjoying these deep dives into Nero's world, and you'd like to see more, there's a small way to keep us going — buy me a coffee dot com slash fexingo. Just the price of a coffee, if it's worth that to you. Luna: Yeah, every little bit helps us keep these episodes free and ad-free. Lucas: So back to the canal — one last detail. When Nero struck that first blow, he was dressed in full Greek regalia, and he reportedly sang a hymn. The whole thing was more like a religious ceremony than a construction site. It tells you everything about how he saw himself: not as a builder, but as a divine hero. Lucas: It's a reminder that for all his flaws, Nero's mind was always reaching for the spectacular. The canal was a monument to his own mythology, even if it never became a monument in stone. Luna: It's strangely poetic, thinking of that unfinished scar in the landscape, all because one man wanted to outdo Hercules. Lucas: And that, I think, is the perfect note to end on. Nero's canal is a tale of ambition and physics, of dreams clashing with reality. But it's also a story about how we remember the past — we don't remember the engineers who quietly built Rome's roads; we remember the emperor who picked up a golden shovel.
