How a catastrophic volcanic eruption preserved an entire Roman city for nearly two millennia
In short: When Mount Vesuvius erupted in 79 CE, it buried Pompeii under a thick blanket of ash and pumice, effectively freezing a sophisticated Greco-Roman society in time. Today, this unique archaeological site offers an unparalleled look at ancient life, from bustling bakeries to the final moments of its terrified citizens.
The destruction of Pompeii was not an instantaneous event but a two-day ordeal. On August 24, 79 CE, around noon, the volcano began showering the city with ash and pumice, which quickly accumulated to a depth of over 9 feet, causing roofs to collapse. By the morning of August 25, lethal surges of hot gas and pyroclastic material reached the city walls, asphyxiating those who had survived the initial debris. Ultimately, the city was entombed beneath 19 to 23 feet of volcanic material, which acted as a perfect preservative for centuries.
Before its demise, Pompeii had a long, complex history. Originally settled by Oscan-speaking people, it fell under the influence of Greeks, Etruscans, and eventually the Samnites. By 89 BCE, the city was besieged by the Roman general Lucius Cornelius Sulla during the Social War. Following the conflict, it became a Roman colony, with Latin replacing Oscan as the official language. By the time of the eruption, the city supported an estimated population of 10,000 to 20,000 people and featured grand public architecture, including an impressive forum and amphitheater.
The site remained hidden until its rediscovery in the 1700s, which sparked a massive 18th-century cultural fascination with classical antiquity. Excavations have since revealed a wealth of detail about daily life, such as loaves of bread still sitting in ovens and the remains of residents caught in their final attempts to flee or shelter. While modern scholars continue to debate the exact date of the eruption—with some suggesting it may have occurred in October or November rather than August—the site remains a vital, albeit fragile, record of the ancient world, designated as a UNESCO World Heritage site in 1997.
