Pompeii & Herculaneum as Evidence
The Day Vesuvius Erupted
On a day in late October AD 79 (the date is now placed in October by most scholars, based on inscriptions and botanical evidence, rather than the traditional August date), the citizens of Pompeii and Herculaneum were going about their ordinary business — buying bread, mending clothes, arguing in the forum, visiting the baths — when Mount Vesuvius, the volcano looming above the Bay of Naples, erupted with catastrophic force. The eruption began in the early afternoon and lasted for around two days. Pompeii was buried under approximately four to six metres of volcanic ash and pumice; Herculaneum, closer to the volcano, was engulfed by a series of pyroclastic surges — fast-moving rivers of superheated gas and volcanic material — that carbonised wood, boiled fluids inside sealed containers, and buried the town under up to twenty metres of hardened volcanic rock. Thousands died. The towns disappeared, unexcavated for over sixteen centuries, until the systematic excavations that began at Herculaneum in 1738 and Pompeii in 1748 began to reveal what lay beneath.
What those excavations revealed was extraordinary: two Roman towns preserved at the moment of their destruction, with streets, buildings, food, clothing, tools, furniture, wall paintings, mosaics, graffiti and human remains still in place. No other site in the ancient world offers anything like this level of detail about ordinary Roman life. Yet the very uniqueness of the evidence also raises questions about how representative these towns are — and historians have debated this for centuries.
Pliny the Younger as a Literary Source
The eruption of Vesuvius was witnessed by Pliny the Younger, who was staying at Misenum, across the bay, with his uncle Pliny the Elder (who commanded the Roman fleet and died attempting to rescue survivors). In two letters to the historian Tacitus, written some years after the event, Pliny the Younger described in vivid detail what he saw: a cloud rising from Vesuvius like a pine tree; his uncle’s decision to sail towards the disaster to help; the falling pumice stones; the darkness; the screaming crowds; and finally, the news that his uncle had died at Stabiae. These two letters (Pliny, Letters 6.16 and 6.20) are among the most famous in all Latin literature, and they provide the main literary account of the eruption.
As a source, Pliny’s letters are invaluable but require careful handling. He was not in Pompeii or Herculaneum himself, so his account of conditions there is at second hand. He was also writing with a literary and self-promoting purpose: to present his uncle as a hero and to place himself as a composed observer in the face of terror. The letters were written for a literary audience and were intended to be read aloud and circulated among educated Romans. They are therefore shaped by rhetorical conventions and the desire to impress, not simply to inform.
Pliny the Younger wrote two famous letters to Tacitus (Letters 6.16 and 6.20) describing the AD 79 eruption. He was at Misenum across the bay, not in Pompeii itself. His uncle, Pliny the Elder, died attempting to help survivors. The letters are vivid literary accounts shaped by rhetorical purpose as well as eyewitness experience.
What Pompeii Reveals: Graffiti and Inscriptions
One of the most distinctive categories of evidence from Pompeii is its graffiti and painted wall inscriptions. Over 11,000 Latin inscriptions have been recorded from Pompeii alone. Some are electoral notices (programmata), endorsing candidates for local magistracies. Others are graffiti in the modern sense: scratched or painted personal messages recording declarations of love, insults, jokes, financial records, and even literary quotations. The collection known as Cooley and Cooley’s Pompeii: A Sourcebook catalogues many of the most important inscriptions, making them accessible to students.
Among the most revealing inscriptions are the Pompeii election notices. One set of programmata, for example, records endorsements from bakers, fruit-sellers, gold-smiths and other trade groups, demonstrating that local elections involved active participation from a wide range of the town’s commercial community. Other inscriptions include gladiatorial announcements, advertisements for properties to let, and lists of prices for goods and services. Taken together, the inscriptions turn the walls of Pompeii into a kind of community noticeboard, capturing the preoccupations and voices of its inhabitants in a way that formal historical texts cannot match.
Herculaneum was buried differently from Pompeii. The pyroclastic surges that destroyed it were so intense that they carbonised organic material rather than simply burying it. This has led to the extraordinary preservation of wooden furniture, food, textiles and even papyrus scrolls (the Villa of the Papyri yielded hundreds of carbonised scrolls, mostly philosophical texts, that scholars are still working to read using new imaging technology). The House of the Wooden Partition at Herculaneum preserves its original upper-storey wooden partition wall — a type of structural element that has not survived at Pompeii — giving us rare direct evidence of how Roman houses were constructed above ground level. The Central (Forum) Baths at Herculaneum preserve their interior fittings in better condition than the baths at Pompeii, allowing detailed study of Roman bathing architecture.
Herculaneum was a smaller and evidently wealthier town than Pompeii. Its streets are narrower, its houses more uniformly prosperous, and the absence of the commercial graffiti so abundant at Pompeii suggests a different social character. The differences between the two towns remind us that there was not one single “Roman city life” but a variety of urban experiences shaped by local character, economic activity, and social composition.
The Value and Limits of the Evidence
The evidence from Pompeii and Herculaneum is extraordinary, but historians must be alert to its limitations. Both towns are preserved at a single moment in time — AD 79 — and both were in an unusual state at the time of the eruption: Pompeii had suffered a major earthquake in AD 62, and some buildings were still being repaired or rebuilt when the volcano struck, although recent archaeology suggests the town was flourishing again rather than enduring seventeen years of disruption. The population that fled (or tried to flee) was not a normal cross-section of Roman society; the very poor and the very rich may have been under-represented in the physical evidence left behind. And both towns are in southern Italy, which was in some respects different from the city of Rome itself, or from cities elsewhere in the empire.
Nevertheless, the sheer quantity and variety of evidence — buildings, objects, inscriptions, human remains, food, tools — means that Pompeii and Herculaneum remain the single most important set of sources for everyday Roman urban life. No other ancient site comes close. The key is to use the evidence carefully: naming specific sites and specific finds, comparing material evidence with literary sources such as Pliny, Juvenal and Petronius, and remaining alert to what the evidence cannot tell us as well as what it can.
The main limitations of Pompeii and Herculaneum as evidence: (1) both are frozen at AD 79, not representative of the whole span of Roman history; (2) Pompeii was disrupted by the AD 62 earthquake; (3) both are provincial Italian towns, not Rome itself; (4) the poor and transient population may be under-represented. The main strengths: unique depth of preservation; wide range of building types; ordinary commercial and domestic life captured; inscriptions and graffiti record ordinary voices.
The physical evidence of Pompeii and Herculaneum gains much of its meaning when read alongside literary sources. Pliny’s letters give us a human perspective on the eruption itself. Juvenal’s Satire 3 describes the noise, squalor and danger of city streets in terms that match what we find in the material evidence. Petronius’s Satyricon provides a fictional but vivid account of a freedman’s dinner party that illuminates the social world behind the houses we excavate. Horace’s Satires describe the pleasures and frustrations of Roman urban life from the perspective of a man of letters. None of these authors is a neutral witness: each writes with literary purposes, for a specific audience, and with his own social position. But each provides a layer of human experience that the physical remains alone cannot supply. The best historical judgements about Roman city life draw on both types of source together.
