Pompeii lay on a ridge of cooled lava overlooking the river Sarno, a few kilometres inland from the Bay of Naples, in the region the Romans called Campania. It stood where roads carrying grain, wine and oil met on their way to the coast. Its earliest inhabitants were Oscan-speaking peoples, later influenced by Greek settlers. Roman power arrived gradually: Pompeii fought against Rome in the Social War of the early first century BC, and after its capture the town was settled with veterans as a Roman colony, probably in 80 BC.

By AD 79 the city covered some sixty hectares and housed perhaps eleven thousand people. It had a forum lined with public buildings, two theatres, a covered exercise hall, and an amphitheatre built around 70 BC, the earliest stone amphitheatre known to survive. Most inhabitants lived in modest houses opening onto the street, with shops or workshops at the front; the wealthy owned villas with painted gardens. Hundreds of election notices, jokes and insults survive on the walls, written by people who expected their words to be read and answered.

Nothing in those messages suggests fear of the mountain. Vesuvius had not erupted for centuries, and although the geographer Strabo observed that its summit looked as though it had once burned, most people regarded it as no more than a high, green ridge. Vineyards covered the lower slopes, and Herculaneum nestled at its foot. Then, seventeen years before the eruption, a powerful earthquake shook the region, damaging temples and houses across Campania. Repairs were still going on in AD 79: archaeologists have found rooms closed off while masons worked, and plaster stacked ready for walls.

Our best account comes from a teenager on the other side of the bay. Pliny the Younger, then about seventeen, was staying at Misenum with his uncle, the naval commander and naturalist Pliny the Elder. Some twenty-five years later, at the request of the historian Tacitus, he wrote two letters describing the eruption. From these we learn of a cloud shaped like a pine tree above the mountain, of pumice and ash falling on the streets of Pompeii, and of a darkness so dense that people could not tell night from day.

Pliny the Elder took a fast galley across the bay to rescue people and to observe the phenomenon closely. He died on the shore at Stabiae, apparently overcome by fumes, though some historians suspect a heart attack. The traditional date of the eruption, 24 August, rests on a later copy of his nephew's letters. Finds made since the eighteenth century have long suggested a later season — braziers, autumn fruit and jars of freshly pressed wine — and in 2018 excavators uncovered a charcoal inscription dated to mid-October, which many scholars now read as evidence that the eruption happened in autumn.

Not everyone died. Many inhabitants had left during the hours of falling pumice, and the remains found so far — more than a thousand — are a fraction of the population. Most of those who died in Pompeii were killed by pyroclastic surges that swept down the mountain after the eruption column collapsed, burying the city under metres of ash and debris. At Herculaneum, closer to the summit, the first surge arrived much earlier; around three hundred skeletons were found in the arched boat sheds on the seafront, where people had gathered hoping to escape by water.

Pompeii vanished from memory quickly, though the site was never entirely forgotten: its name survived in local place-names. In 1709 a well-digger at Herculaneum struck the marble seats of a buried theatre, and digging there began under Austrian control; systematic work at Pompeii started in 1748 under the patronage of Charles of Bourbon, king of Naples. These early campaigns were treasure hunts, run by engineers who tunnelled for statues and frescoes and reburied what did not interest them, a practice criticised by the art historian Winckelmann.

The modern discipline dates from Giuseppe Fiorelli, appointed to direct the excavations in 1863. He divided the site into the regions, blocks and numbered houses still used in every guidebook, and recorded where objects were found. Most memorably, he poured liquid plaster into the cavities left by bodies in the hardened ash, producing casts of people at the moment of death. The technique has been refined since the 1980s, when some casts began to be made in clear resin, allowing bones and the shapes of clothing to be studied rather than hidden.

Excavation continues, and the site is in constant danger from rain, vegetation and its own visitors. The Great Pompeii Project, financed largely by the European Union from 2012, repaired embankments and drained water from behind walls. Attention has also turned to the villa at Civita Giuliana, where excavators found a stable with the remains of horses, a ceremonial chariot with bronze fittings, and the bodies of two men, thought to have been an owner and an enslaved servant, caught in a narrow corridor.

What survived is not a Roman town frozen at an ordinary moment. It was a busy port that had been battered by an earthquake and was, in AD 79, partly a building site. Nor is everything in its museums from the town itself: some objects came from villas outside the walls, and many statues are copies. Yet no other Roman city gives such direct access to the ordinary fabric of daily life — to bakehouses, laundries, brothels and election slogans — and it remains one of the most important archaeological sites in the Mediterranean.

Wheat is the most widely grown crop on earth, and almost none of it could survive without people. The plant that farmers harvest today is the descendant of wild grasses that grew in the hills of the Middle East, and the changes that turned those grasses into a crop — a sturdier ear, larger grains, seeds that wait to be sown — were the foundation of farming. Wheat was among the first plants to be domesticated, roughly ten thousand years ago, in a region stretching from the Levant through south-eastern Turkey into western Iran. Along with barley, lentils, peas, chickpeas and flax, it belongs to what archaeologists call the founder crops of Eurasian agriculture.

The most important change concerns the ear, the structure at the top of the stem that holds the grains. In wild wheat, the ear breaks apart when the grain is ripe: the stalk, or rachis, snaps at each joint so that the seeds scatter on the ground. That suits a wild plant but not a farmer, who needs the grain to stay on the stem until harvest. A few wild plants carry a mutation that leaves the ear intact, and these would have been gathered in greater numbers. Once people began sowing seed from their own fields, the trait spread rapidly, because grain from a tough-eared plant all ends up in the basket. Domesticated wheat cannot disperse its own seed; it depends on being threshed and sown.

Two species were involved at the start. Einkorn is a diploid wheat, with two sets of chromosomes, descended from a wild grass of the same region. Emmer is a tetraploid, with four sets, the product of a much older hybridisation between two wild grasses. Both were domesticated, apparently independently, and both were grown across the Near East. Genetic comparisons between domesticated einkorn and its wild relatives point to a region of south-eastern Turkey as the place where the process began. Wild emmer has a wider natural range, and the arguments about exactly where it was first cultivated continue.

Reconstructing all this from plant remains is difficult, and the difficulty shapes the conclusions. Most plant material rots; what survives on early sites is chiefly grain and chaff that were burnt, often accidentally, in fires or in the ovens used for drying. Some survives as impressions pressed into mud brick or pottery. Archaeobotanists sieve soil from pits and floors, identify the fragments under a microscope and count them. The DNA in charred grain is largely destroyed, so identification rests on shape and anatomy, and the crucial evidence — the joints of the rachis — is small enough to be missed by a coarse sieve. The record is therefore not merely thin but biased towards whatever happened to be burnt.

This has fed a long argument about how domestication happened. One view treats it as a relatively rapid event: once people began cultivating, the tough-eared plants were favoured so strongly that the change appeared within a few generations. The other, now widely influential, describes a protracted process in which cultivation came first and domestication followed slowly. On this account, farmers sowed and harvested wild plants for centuries, perhaps millennia, while the proportion of tough-eared individuals in their fields crept upwards. Nobody intended to create a new species; the change was a by-product of harvesting and sowing. The two models are not entirely incompatible, since the pace would have varied from place to place.

Bread wheat, the species that now dominates world production, has a more complicated ancestry. It is a hexaploid, with six sets of chromosomes, and it arose when domesticated emmer met a wild grass called goat grass (Aegilops tauschii). Recent genetic work suggests that the relevant population of goat grass lived south of the Caspian Sea. The crossing itself most likely happened in a farmer's field rather than in the wild, in a place where the two plants grew side by side. The result was a wheat whose gluten made it suitable for leavened bread, and which could be grown across a far wider range of climates than either of its parents.

From the Fertile Crescent, wheat travelled. Farming had reached Greece by about 6500 BC, central Europe by 5500 BC and Britain by around 4000 BC. Emmer and einkorn went with it, alongside barley, lentils and peas. The free-threshing wheats, whose grain separates easily from the chaff, became steadily more common, and bread wheat eventually spread across the temperate world. Einkorn was largely abandoned, surviving in a few mountain regions, while emmer persisted for thousands of years before durum, its close relative, replaced it in most Mediterranean fields. Barley tolerated poorer soils and drier conditions than wheat, and it remained important wherever wheat struggled.

The history matters because of what has been lost. Centuries of selection, and then a century of scientific breeding, narrowed the genetic range of the crop at a time when farmers need varieties that can withstand heat, drought and new diseases. The wild relatives of wheat, and the old landraces still grown in a few places, hold traits that the modern varieties lack. Collections of seed are kept in genebanks, but the plants themselves are disappearing from the field, which is why some researchers argue that the deepest history of wheat is also a practical question. Breeders can cross modern varieties with their wild relatives, but moving a single useful gene into a popular variety remains slow and uncertain.

A claim about the past can travel further in a day than most academic monographs travel in a decade. A photograph of a carved stone is posted with a caption asserting that it proves a forgotten civilisation; a short video explains that a medieval building was designed as an astronomical calendar; a thread insists that a familiar event has been deliberately misdated. Some of these claims are harmless, some are not, and a good many are simply wrong. Historians are increasingly asked, by journalists, teachers and their own students, what they intend to do about it.

The case for answering is strong. Most people's contact with the past now happens on screens, and the audiences for online history are enormous. If professional historians stay away, the field is left to whoever is most confident and most entertaining, and confidence is not the same as accuracy. Public money pays for universities and museums, and those who benefit from that funding arguably have a duty to share what they know. It is also worth remembering that most people who pass on a dubious claim are not trying to deceive anyone; they are repeating something they found convincing, and no one has shown them how historians test a story.

Yet the case against is not trivial. Academic careers are built on research, teaching and publication in specialist journals; time spent explaining the past to strangers earns little credit and can even be treated with suspicion by colleagues who see it as self-promotion. Historians who do it regularly receive abuse, much of it aimed at their gender, race or expertise, and institutions are slow to protect them. There is also a mechanical problem. A correction that quotes the false claim in order to refute it hands the platform another piece of material to circulate, and platforms reward whatever provokes a reaction.

Worse, a correction is often delivered in a form that cannot do the work asked of it. A flat denial — 'this is false' — gives the reader no way of judging between the historian and the original poster, since both appear simply to be asserting. Research on how people respond to corrections suggests that they are more effective than pessimists once claimed: people do revise details. But the same research indicates that corrections rarely shift a belief that has become part of how someone sees themselves or their community. What seems to matter is not the volume of the correction but whether the reader has a reason to trust the person offering it.

What historians can offer, therefore, is not primarily a verdict but a method. A specialist asked whether a building encodes an astronomical calendar can show what the surviving documents actually record, explain how the stonework is dated, and describe what evidence would have to exist for the claim to be plausible. Presenting a provisional conclusion as settled fact misrepresents how the subject actually works. The method is slower and less satisfying than a one-line refutation, and it has an uncomfortable consequence: it requires historians to be explicit about the limits of what they know. Admitting ignorance is not a weakness; it is where trust begins.

There is a further complication that historians rarely admit in public. Professional history has generated myths of its own. National narratives that present a country's past as a story of steady progress, or that quietly omit the uncomfortable parts, have been produced by trained scholars as often as by popular writers, and they are far harder to dislodge than a forged photograph because they were built into school textbooks and public monuments. Social media did not invent the misleading story about the past; it accelerated it.

Nor is the audience a single thing. A schoolchild watching a video about the Romans, a retired engineer reading a thread about a local church and a journalist looking for a quotation need quite different things, and a message designed for one may mislead another. Readers' questions, historians often find, are more demanding than the ones they expected.

What, then, should be done? Historians should not work alone: museums and archives have begun to employ staff specifically to answer questions online, and teachers are the most effective allies, because they can show a class how a claim is tested rather than simply announcing the answer. Institutions should recognise this work when they award promotion and should protect the people who do it. Above all, they should resist the pressure to answer within the hour; a considered reply the next day is worth more than a hurried one that misses the point.

My own position is that historians should engage, but not on the terms the platforms set. The aim is not to win the argument of the day or to collect followers, still less to humiliate the person who shared the misleading post. It is to leave the reader slightly better equipped to judge the next claim, and the one after that. That means showing the evidence, stating the uncertainties, and being willing to say that a question has not yet been settled. A generation taught to ask how we know will be harder to mislead than one taught only what to believe.
