The volcano that buried two cities—and gave us a word
Trivia of the Day
What ancient Roman city, buried alongside Pompeii in 79 CE, was actually wealthier and discovered first—yet remains far less famous?
- Herculaneum
- Stabiae
- Oplontis
- Neapolis
Answer: Herculaneum — Herculaneum was so perfectly preserved by volcanic mud that wooden furniture, food, and even a complete library of scrolls survived intact—something impossible in ash-covered Pompeii.
When Mount Vesuvius erupted on August 24, 79 CE, it destroyed not one but several cities. Herculaneum, a seaside resort town for Rome's ultra-wealthy, stood closer to the volcano than Pompeii and met a different fate. While Pompeii choked under ash and pumice, Herculaneum was engulfed by a superheated pyroclastic surge that turned to rock-hard volcanic mud, sealing the city in a protective cocoon sixty feet deep.
The preservation was extraordinary. Archaeologists found two-story wooden houses still standing, complete with beds, tables, and food on shelves. An entire library of philosophical texts survived—the only intact library from antiquity. Fishing nets hung on walls. Loaves of bread sat carbonized but recognizable in ovens. The mud even preserved the biological structure of the victims' brains.
Yet Herculaneum remains Pompeii's forgotten sibling. Rediscovered in 1709—thirty-nine years before Pompeii—it seemed destined for fame. But that same mud that preserved it so beautifully made excavation brutally difficult and expensive. The modern town of Ercolano sits directly above the ancient city, making large-scale excavation impossible. Pompeii, by contrast, lay under farmland and offered dramatic, accessible ruins perfect for 18th-century Grand Tourists.
Today, only about four city blocks of Herculaneum are excavated, compared to Pompeii's sixty-six acres. What remains buried likely includes the town's upper stories and wealthiest villas. Scholars believe 80% of Herculaneum still waits underground, frozen in time, beneath a modern Italian town—the greatest archaeological site we can see but cannot reach.
Word of the Day
pyroclastic adjective · py-roh-KLASS-tik
Relating to fragments of rock erupted by a volcano, especially as part of a devastating, superheated cloud of gas and debris. From Greek pyr (fire) and klastos (broken), this term emerged in the 1870s as geologists struggled to describe volcanic phenomena that shattered and incinerated simultaneously.
“The pyroclastic flow raced down the mountainside at 450 miles per hour, obliterating everything in its path before anyone could react. In the lab, researchers examined pyroclastic deposits to reconstruct the sequence of ancient eruptions.”

Why did the archaeologist refuse to excavate Herculaneum?
They didn't want to dig themselves into a hole under someone's living room.
This Day in History
79 — Mount Vesuvius erupted in one of history's most catastrophic volcanic events, burying Pompeii, Herculaneum, and several smaller towns under ash and superheated debris. The eruption killed an estimated 16,000 people and was so violent that its column of gas and pulverized rock reached twenty miles into the stratosphere. Pliny the Younger witnessed it from across the Bay of Naples and wrote the first detailed eyewitness account of a volcanic eruption, giving us both the historical record and the term 'Plinian eruption' for this type of explosive event. The cities remained buried and largely forgotten for over 1,600 years, becoming a time capsule of Roman life frozen at the peak of the empire.
