Pompeii: Archaeology's Most Detailed Snapshot of Roman Life
Pompeii, buried under 4–6 metres of volcanic tephra when Vesuvius erupted on 24 August 79 CE (or possibly 24 October, as some recent evidence suggests), is the single most informative source for Roman daily life that exists. It was not a typical Roman city — the burial conditions that made it famous are exceptional — but what it preserves is genuinely irreplaceable: the street plan, domestic architecture, commercial frontages, electoral graffiti, workshop equipment, food residues, and bodily casts of the people who did not escape the eruption. The site covers approximately 66 hectares; roughly two-thirds have been excavated since systematic work began in 1748. The ongoing excavations in Regio V, begun in 2017, have produced extraordinary new finds that demonstrate how much the site still has to reveal.
The Eruption
Vesuvius produced a Plinian eruption — a column of ash and gas rising 20–30 km into the stratosphere — that deposited several metres of pumice and ash (lapilli) on Pompeii, 10 km to the south-east. The bulk of Pompeii's victims died from the pyroclastic surges that followed the column collapse in the early hours of the following morning; these fast-moving flows of hot gas and ash suffocated anyone who had sheltered in place and did not kill by fire but by thermal shock and asphyxiation. The temperature of the surge material reaching Pompeii is estimated at 250–300°C — sufficient to kill instantly and to carbonise organic material rather than burn it.
The covering tephra sealed the city in a moment, preventing the gradual decay of organic materials that takes place in normally buried sites. Wood, food, cloth, rope, and leather survived as carbonised or desiccated residues; the plaster casts made by Giuseppe Fiorelli from 1863 onwards — pouring liquid plaster into the voids left by decomposed bodies in the ash matrix — preserve the precise posture and clothing details of people killed in the surge.
Domestic Architecture
Pompeii preserves a complete typology of Roman domestic architecture from the modest one-room shop-dwelling (taberna) to the grand atrium house with peristyle garden. The House of the Faun, the largest private residence in Pompeii at 3,000 square metres, contained both an Italic atrium complex and a Hellenistic peristyle garden, and produced the Alexander Mosaic — a monumental floor mosaic depicting Alexander the Great at the Battle of Issus (333 BCE), now in the Naples National Archaeological Museum. The House of the Vettii, restored to accommodate visitors, still has its painted walls in place and provides the most atmospheric experience of a Pompeian domestic interior.
The atrium house plan — with a central open hall (atrium) containing a collecting pool (impluvium) aligned with a skylight (compluvium), flanked by cubicula (bedrooms) and leading to a tablinum (study or reception room) that opened onto the garden — is attested in dozens of examples at Pompeii, giving a sample large enough for systematic architectural analysis impossible at any other site.
Commerce and Food
The commercial life of the city is uniquely well documented. The street frontages of Pompeii are lined with thermopolia — hot food and drink counters with sunken ceramic containers (dolia) for different food preparations, a street-food infrastructure comparable to modern fast-food environments. Over 80 thermopolia have been identified; the Thermopolium of Regio V, excavated 2019–2021, was found with food residues still in its dolia: pork, fish, snails, and duck bones, with paintings depicting food items above the counter as a kind of ancient menu. This is the most complete Roman food service installation ever found.
The production and distribution of food within the city is documented by at least 35 identified bakeries (pistrina), each equipped with rotating lava millstones and a domed bread oven. A bakery excavated in Regio IX in 2023 was found with carbonised loaves still in the oven — round, scored, divided into sections as in modern pane di Altamura — alongside the skeletal remains of probable slaves found in a locked room.
The New Excavations: Regio V
The ongoing Pompeii Archaeological Park excavation programme in Regio V (the unexcavated north-eastern quarter of the city), funded by the Grande Progetto Pompeii, has produced a series of internationally reported finds since 2017: an intact ceremonial chariot with iron, bronze, and bone decoration (2021); the thermopolium described above; a room decorated with erotic frescoes (2021); a blue painted ritual room (sacrarium) with carbonised wooden objects; a fast-food establishment with the food still present; and most recently (2023), a complete bakery with enslaved workers' remains that has prompted significant debate about the conditions of enslaved labour in Roman urban life.
Herculaneum
Often overlooked in favour of Pompeii, Herculaneum 15 km to the north-west was buried under pyroclastic surge deposits 20 metres deep, preserving organic material — wooden furniture, food, papyrus scrolls, and wooden structural elements — in exceptional condition. The town is smaller than Pompeii, with perhaps 4,000 residents; only a quarter of the site has been excavated. The Villa of the Papyri, buried outside the town, contained the only library to survive from antiquity: approximately 1,800 carbonised Greek papyrus scrolls, most of which were too fragile to unroll without destroying them. New virtual unrolling techniques developed at the University of Kentucky (the Vesuvius Challenge, 2023–2024) have successfully read text from never-opened scrolls using X-ray phase-contrast tomography and machine learning.
Visiting Pompeii
The site is located in the comune of Pompei south of Naples, served by the Circumvesuviana railway from Naples Garibaldi station. Entry is via the Porta Marina, Porta Anfiteatro, or Piazza Esedra entrances; the site is large enough to require two full days for thorough coverage. The Antiquarium on the site displays finds from recent excavations including the Regio V material. The Naples National Archaeological Museum holds most of the major finds from the entire Vesuvian area including the Alexander Mosaic and the Secret Cabinet of erotic material.
