Everyone knows Pompeii. The frozen bodies. The plaster casts. The tourists.

But just a few miles down the coast, buried under nearly 20 meters of volcanic rock, lies a city that Pompeii can’t compete with. A city so well preserved that you can still see the food sitting on the shelves. The wooden furniture. The doors. The beds.

Its name is Herculaneum. And most people have never heard of it.

When Mount Vesuvius erupted in AD 79, both cities died — but they died differently. Pompeii was buried under hours of falling ash and pumice, which crushed roofs, collapsed walls, and let oxygen in slowly, rotting away anything organic. What survived at Pompeii was mostly stone.

Herculaneum got something else entirely. A superheated pyroclastic surge — a wall of volcanic gas and debris moving at catastrophic speed — hit the city almost instantly. The heat was so extreme it carbonized everything in its path. Wood. Food. Fabric. Papyrus. Sealed it all under nearly 65 feet of what eventually hardened into cement-like tuff rock, cutting off oxygen for two thousand years.

The result is unlike anything else in the archaeological world. At Herculaneum, you don’t have to imagine what a Roman home looked like. You can see it.

The Dead Who Waited at the Shore

For a long time, archaeologists believed most of Herculaneum’s population had escaped. Unlike Pompeii, the city showed almost no human remains — which seemed to suggest the residents fled in time.

That assumption collapsed in the 1980s.

Excavations along the ancient shoreline uncovered twelve stone boathouses — and inside them, the remains of more than 300 people. Men, women, children. They had crowded into the seafront structures, probably waiting for rescue boats that never came. Between 1980 and 2020, the remains of 340 victims were found along the Herculaneum coast in total.

Analysis of the skeletons was disturbing. The pyroclastic surge that hit Herculaneum reached temperatures of around 500 degrees Celsius — roughly 932 degrees Fahrenheit. At that heat, death was not slow. Researchers found evidence of blood vaporization, exploded skulls, and limbs contracted from thermal shock. People died in seconds.

Among the skeletons, specific stories began to emerge. One skeleton, first found in the 1980s near the remains of a boat, is now believed to belong to a senior Roman soldier — identified by his belt and military weapons — likely sent on a rescue mission. Another, called the “Ringed Lady,” was found with emerald and ruby rings still on her fingers. In 2021, archaeologists found the bones of a man between 40 and 45 years old just steps from the shoreline — stained black and red, the color left by blood. They called him “the last fugitive.”

A Brain Turned to Glass

In 1961, Italian archaeologist Amedeo Maiuri found a skeleton in a small room of the Collegium Augustalium — a public building dedicated to the worship of Emperor Augustus. The body was face-down on the charred remains of a wooden bed. Maiuri identified the victim as male, approximately 20 to 25 years old, probably the building’s caretaker. Possibly asleep when Vesuvius erupted.

Inside the skull, there was something no one had ever seen before at either Herculaneum or Pompeii. Fragments of black, glassy material.

Decades passed before anyone understood what it was.

In 2020, a scientific team led by forensic anthropologist Pier Paolo Petrone of the University of Naples Federico II finally analyzed the material using a scanning electron microscope. The results were published in the New England Journal of Medicine. The glassy fragments contained proteins found in brain tissue, and fatty acids consistent with human hair. Analysis of charred wood at the site indicated the temperature at the moment of death had reached approximately 968 degrees Fahrenheit.

The heat had been so sudden, so extreme, that the victim’s brain had not decayed. It had not simply burned. It had vitrified — turned to glass. And inside that glass, researchers found something even more unexpected: preserved neurons and axons. Neural structures, intact, from a human being who died in AD 79.

It is the only known case of a vitrified human brain in the archaeological record.

The Library That Shouldn’t Exist

In the mid-18th century, workers digging beneath the modern Italian town of Ercolano stumbled into a villa unlike anything seen before. The Villa of the Papyri — believed by many scholars to have belonged to Lucius Calpurnius Piso Caesoninus, the father-in-law of Julius Caesar — contained the only intact library to survive from the ancient world.

Inside were hundreds of rolled papyrus scrolls. Carbonized by the eruption, they looked like lumps of charcoal. Attempts to physically unroll them caused them to crumble instantly. For nearly 300 years, the scrolls sat unread — their contents locked inside.

Then came the Vesuvius Challenge.

In 2023, computer scientist Brent Seales of the University of Kentucky launched a global competition with a prize fund of over one million dollars — offering cash rewards to anyone who could use machine learning to decode text from the carbonized scrolls without physically opening them. Researchers used high-energy X-ray scanners and 3D imaging to map the interior structure of the rolls, then trained AI models to detect ink traces on the ancient papyrus.

By the end of 2023, a team of three students — Youssef Nader from Germany, Luke Farritor from the United States, and Julian Schilliger from Switzerland — won the $700,000 grand prize after successfully identifying more than 2,000 Greek characters from one scroll. The text, translated by papyrologists, turned out to be a previously unknown work discussing the nature of pleasure — most likely written by Epicurean philosopher and poet Philodemus of Gadara, who lived from around 110 to 30 BC.

In February 2025, a particle accelerator and AI tools were used to decode further text from a second scroll, PHerc. 172, revealing words including “foolish,” “disgust,” “fear,” and “life.”

Scholars believe the villa’s main library was never found. Entire levels of the site remain unexcavated. Thousands more scrolls could still be buried beneath the modern city above. Every one of them sealed for two thousand years — and possibly still readable.

Pompeii gave the world a monument to disaster. Herculaneum is still giving us something rarer: the actual thoughts of people who lived before the mountain buried everything they knew.
