What's the biggest archaeological find in history?

Identifying the biggest archaeological find in history is sort of like naming the best movie ever made. One person's blockbuster could be another person's bust. Still, there are ways to make the decision less subjective. One way requires a checklist to help evaluate the merits of various archaeological finds. Our handy checklist contains five questions:

  1. Does the find amaze with its details, clarity or size?
  2. Does the find advance the field of archaeology in a significant way?
  3. Does the find revise our thinking on a particular aspect of history?
  4. Does the find capture the imagination of non-scientists?
  5. And does the find help prepare us for the future?

We applied these questions to a who's who of archaeological discoveries. For example, we considered the Rosetta Stone, an ancient Egyptian stone bearing three languages that enabled scientists to decipher hieroglyphic writing. We considered the Dead Sea Scrolls, a collection of manuscripts found on the northwestern shore of the Dead Sea that provided insights about the rise of Christianity and the relationship between Christian and Jewish traditions. We considered the tomb of Tutankhamen, the boy king who ruled Egypt between 1333 and 1323 B.C. And we considered "Lucy," a 3.2-million-year-old hominid -- Australopithecus afarensis -- discovered in Hadar, Ethiopia, by Donald Johanson.

But our choice for biggest archaeological find in history is not a stone, a scroll or a skeleton -- it's Pompeii, an ancient city located on the plain of Campania in southern Italy. Pompeii was founded in the 6th century B.C. and became incorporated into Rome by 80 B.C. As a Roman colony, the city bustled with life and activity, supporting somewhere between 10,000 and 20,000 inhabitants.

Then a series of man-made and natural disasters struck the city. First, in A.D. 59, a riot between the Pompeians and the Nucerians erupted in the amphitheater. Next came an earthquake, which destroyed much of the city in A.D. 62. Finally, on Aug. 24, A.D. 79, Mount Vesuvius erupted and buried Pompeii beneath nearly 9 feet (3 meters) of ash, pumice and other volcanic debris. The city lay undiscovered -- and almost perfectly preserved -- for almost two millennia. Formal excavations began in 1748 and have continued to this day.

Pompeii Takes the Prize

To understand the significance of Pompeii, let's revisit the checklist we introduced earlier and answer the first few questions.

Does the find amaze with its details, clarity or size?

The sheer size of the Pompeian ruins is astonishing. The city's ancient walls surround 163 acres of land, 1,500 buildings and miles of roads. Only a third of the city remains buried, although most of the territory outside the walls -- Pompeii's suburbs, if you will -- has never been touched. The areas that have been excavated reveal amazing details, all perfectly preserved by the fine volcanic powder that showered down from Vesuvius. Archaeologists have found mosaics, frescoes and statues in perfect condition, glass jars still holding fruit, brick ovens loaded with loaves of bread and graffiti scribbled across the walls of Pompeian homes.

Does the find advance the field of archaeology in a significant way?

Archaeologists have been working without interruption at Pompeii since the mid-18th century, making it the longest continually excavated site in the world. In fact, when scientists first began uncovering the ruins, they ushered in the modern science of archaeology. Over the years, virtually every technique, tool or technology introduced to the field has been tested at Pompeii. For example, Giuseppe Fiorelli, the Italian archaeologist who first organized and managed the excavations at Pompeii, developed the technique of making plaster casts of bodies entombed in the ash. Fiorelli was able to create casts revealing remarkable details, even facial expressions.

Does the find revise our thinking on a particular aspect of history?

No site provides more information about ancient Greco-Roman life than Pompeii. In essence, an entire ancient city was frozen in time, allowing researchers to study every aspect of Roman culture. Much of the early archaeological work focused on the physical structure of the city, including its public buildings and private homes. This research has made it possible to trace four centuries of Roman architecture and even urban planning.

Over the years, archaeologists have also delved into of the social and religious lives of Pompeii's residents. For example, scientists know now that most of the city's inhabitants weren't wealthy homeowners loaded with jewels and expensive artwork. Most lived humble lives in modest homes. Many were slaves, who served their masters faithfully until the eruption began and, in some cases, perished with them while trying to escape.

Another Avellino Eruption on the Way?

Maybe you're beginning to get the idea why we selected Pompeii. So far, it's yes, yes and yes, in case you're keeping track. Let's address those final two questions we asked about the biggest archaeological find in history.

Does the find capture the imagination of non-scientists?

From the moment it was discovered, Pompeii galvanized the interest of people all over the world. As word of the excavations spread, visitors flocked to the site to see the ruins for themselves. Artists came, as well, and after viewing the mosaics, frescoes and architecture of the city, infused their works with Pompeii's Neoclassic style. Today, more than 2 million people make the trek to the ancient city each year.

Does the find help prepare us for the future?

The famous eruption of A.D. 79 wasn't the first for Mount Vesuvius. In fact, scientists now believe that Vesuvius blew its top 22,500 years ago, 17,000 years ago, 15,000 years ago, 11,400 years ago, 8,000 years ago, 3,780 years ago and then the Pompeii-burying event nearly 2,000 years ago. The eruption that occurred 3,780 years ago -- geologists refer to it today as the Avellino eruption -- was even more catastrophic and wide-ranging than the A.D. 79 event.

Given the violent history of Vesuvius, geologists now worry that Naples and the surrounding areas could face a similar catastrophe at any moment. In 2005, a team of scientists led by Giuseppe Mastrolorenzo and Michael Sheridan published a paper in the Proceedings of the Natural Academy of Sciences in which they used the Avellino event as a worst-case scenario for a future eruption of Vesuvius. Based on their analysis, Sheridan and Mastrolorenzo calculated that the odds of a significant eruption increase with each passing year. They also predicted that such an event would be big enough to threaten people as far away as Naples and encouraged the city to update its emergency plan accordingly.

It is, perhaps, this glimmer of the future that elevates Pompeii above other archaeological treasures. If lessons from A.D. 79 can help protect millions of people from a future eruption of Vesuvius, then it truly is a find among finds.
