Latest / Marcus Aurelius: Rome's Philosopher King — Fexingo History / Marcus Aurelius and the Antonine Plague's True Toll
Transcript
- Lucas: So we've talked a lot about Marcus Aurelius as a Stoic philosopher-emperor, but one thing that hangs over everything he did is a disease we haven't really dug into yet: the Antonine Plague. Luna: Right, it's been mentioned in passing a few times — the death toll, the military impact — but we never stopped to look at it properly. Lucas: Exactly. And it's fascinating because it's one of the earliest well-documented pandemics in history, and it directly shaped the course of Marcus's reign. It first appeared in 165 CE, while Roman troops were campaigning in the East under Lucius Verus. Lucas: The consensus among modern historians is that it was almost certainly smallpox — Variola major. The symptoms described by Galen, who was Marcus's personal physician, include fever, sore throat, diarrhea, and a pustular rash that started on the face and spread. That's textbook smallpox. Luna: So Galen himself documented it? That's incredible — we have a first-hand medical account. Lucas: We do. Galen wrote about his clinical observations, though he didn't use modern terminology. He called it the 'Antonine plague' after the imperial family name. But he did describe the 'exanthema' — the rash — and noted that some patients developed black pustules, which suggests a severe hemorrhagic form. Lucas: The disease spread like wildfire through the army. Roman soldiers returning from the siege of Seleucia on the Tigris in 165 brought it back with them. It then swept through the empire, reaching Rome by 166 and persisting in waves for at least fifteen years. Luna: How many people died? I've heard numbers ranging from a few million to half the population. Lucas: The estimates are tricky because Roman census data is fragmentary. But most modern scholars, like Richard Duncan-Jones, put the overall mortality at around 20 to 30 percent of the population in affected areas. In some cities, it might have been higher. Cassius Dio mentions that at the peak in Rome, two thousand people died per day. Lucas: If we extrapolate from that, the empire lost somewhere between five and ten million people over the course of the outbreak. That's comparable to the Black Death in Europe proportionally. Luna: And this is happening while Marcus is trying to fight the Marcomannic Wars on the Danube. That must have been a logistical nightmare. Lucas: It absolutely was. The plague decimated the legions. Recruitment became desperately difficult. Marcus had to conscript slaves, gladiators, and even barbarian mercenaries to fill the ranks. There's a story — maybe apocryphal — that he auctioned off imperial palace treasures to raise funds because the treasury was so depleted. Lucas: And this is where the Stoic philosophy kicks in. In his Meditations, Marcus writes things like: 'A plague is just one of the things that happens in nature. It's not good or bad — it's just an event. What matters is how you respond.' He tried to maintain equanimity even as the empire crumbled around him. Luna: I suppose if anyone could handle a pandemic with Stoic calm, it would be him. Lucas: True. But we also have to remember that the plague likely killed Lucius Verus in 169, though some sources say it was a stroke. And it may have contributed to the instability that led to the revolt of Avidius Cassius in 175. People were desperate, and that breeds unrest. Lucas: For anyone coming with us through these conversations about Mediterranean history, I think it's worth taking a moment to appreciate something. This show — all of Fexingo History — we deliberately don't run ads. No sponsors, no commercials. That's a choice we make because we want these episodes to feel like a genuine conversation, not a product. Luna: Yeah, and it really makes a difference. It lets us follow the thread wherever it goes without interruption. Lucas: Exactly. So if you value that approach, and you want to help keep it ad-free, the simplest way is just to buy us a coffee. The link is buy me a coffee dot com slash fexingo. It's a small gesture, but it directly supports the research and production time. Luna: And we really appreciate every bit of support. Now, back to the plague — one thing I've always wondered: did the Antonine Plague permanently weaken the empire, or did it bounce back? Lucas: That's a great question, and the answer is nuanced. In the short term, it caused severe demographic and economic disruption. But the Roman Empire did recover to some extent under the Severans. However, it left a lasting scar. Population decline made it harder to defend the borders, and that contributed to the crisis of the third century. Lucas: There's also evidence of a long-term shift in religious and cultural attitudes. People turned more to mystery cults and Christianity offered explanations and community in the face of suffering. The plague may have accelerated the spread of Christianity. Luna: So it's not just a medical event — it's a historical turning point. Lucas: Absolutely. And there's one more fascinating angle: the archaeological evidence. In the 1990s, a mass grave was discovered in Rome near the Via Tiburtina, containing the skeletons of hundreds of people buried in a hurry. Forensic analysis showed signs of disease consistent with smallpox. It's a direct physical link to that pandemic. Lucas: Galen also noted that the disease was especially deadly for pregnant women and children. That demographic impact would have been devastating for generations. Luna: I remember reading that the plague might have been what killed Marcus himself, eventually. Is that true? Lucas: It's possible. He died in 180 CE at his military headquarters in Vindobona — modern Vienna. Cassius Dio says he had been ill for some time, possibly with a recurrence of the plague. But we can't be certain. Some sources say he starved himself to death after Commodus broke his spirit, but that seems more like a rumor. Lucas: What we do know is that his last words, according to tradition, were: 'Go to the rising sun, for I am already setting.' That's a pretty Stoic exit. Luna: It really is. So the plague bookends his reign — it starts around the time he becomes sole emperor, and it's still there when he dies. Lucas: Exactly. And it's a reminder that even the most powerful man in the world was subject to the same natural forces as everyone else. Stoicism wasn't just a philosophy for Marcus — it was a survival strategy. Lucas: If you want to read more about the Antonine Plague, a great starting point is 'Pandemics and the Ancient World' by Kyle Harper, or Galen's own 'Methodus Medendi'. They paint a vivid picture of how people experienced disease in antiquity. Luna: I'll definitely check that out. For now, though, I think we've covered a lot of ground on a topic that doesn't always get the attention it deserves. Lucas: Glad we finally gave it a proper look. Next time, maybe we'll talk about the legacy of the Antonine Plague in later Roman history, or we could pivot to something completely different. Let's see where the research takes us.
