The charred Herculaneum scrolls can never be read
Changed in2026TaughtThe library of carbonized papyrus scrolls from Herculaneum, charred solid by the same eruption that buried Pompeii, is unreadable. Unrolling them destroys them, so their contents are lost forever, a whole ancient library we can see but never open.
NowThey can be read without being opened. Using high-resolution CT scans and machine learning, the Vesuvius Challenge recovered the first words in 2023 and full passages in 2024, and in 2026 an entire scroll, PHerc. 1667, was virtually unwrapped and read end to end for the first time.

Pompeii was buried and abandoned in 79 CE
Changed in2025TaughtMount Vesuvius buried Pompeii in 79 CE, killing its inhabitants and sealing the city under ash. It lay empty and forgotten until its rediscovery and excavation in the eighteenth century.
NowExcavations reported in 2025 show people moved back into the ruins after the eruption and lived there for centuries. Survivors and newcomers built dwellings among the buried upper storeys, with coins, ceramics, ovens, and oil lamps documenting occupation from the late first century into the fifth.

We have no idea what a Denisovan looked like
Changed in2025TaughtDenisovans are an extinct human relative known only from a few teeth and a finger bone from a Siberian cave. We have their DNA but no skull, so we don't know what they looked like.
NowIn 2025, molecular analysis identified the near-complete 'Dragon Man' skull from Harbin, China, as Denisovan, giving the group its first face. Ancient proteins and DNA from the skull's tooth plaque tied the massive, heavy-browed cranium, at least 146,000 years old, to the Denisovan lineage.

Stonehenge's Altar Stone came from Wales
Changed in2024TaughtStonehenge's bluestones, including the large recumbent Altar Stone at the center, were brought from the Preseli Hills in west Wales, roughly 150 miles away.
NowA 2024 Nature study showed the six-tonne Altar Stone does not match Welsh rock at all. Its mineral ages and chemistry match the Orcadian Basin of northeast Scotland, more than 460 miles (750 km) away, the longest-distance megalith transport known from Neolithic Europe.

TaughtThe earliest figurative cave paintings are the European ones, Chauvet and Lascaux in France, Altamira in Spain, and Europe is where prehistoric art and visual storytelling began, around 30,000 to 40,000 years ago.
NowIn July 2024, a scene on the Indonesian island of Sulawesi was dated to at least 51,200 years ago, making it the oldest known figurative art anywhere. It shows three human-like figures around a wild pig, which also makes it the oldest known example of narrative storytelling in art.

The world is in a COVID-19 public health emergency
Changed in2023TaughtCOVID-19 is a Public Health Emergency of International Concern: the World Health Organization's highest level of global alarm, declared on 30 January 2020. The world is in an active, emergency phase of the pandemic.
NowOn 5 May 2023, the WHO declared that COVID-19 is no longer a public health emergency of international concern, ending the emergency phase after more than three years as immunity rose and deaths and hospitalizations fell.

The Inca city is named Machu Picchu
Changed in2022TaughtThe famous Inca citadel in the Andes is called Machu Picchu, the name it has carried since Hiram Bingham brought it to the world's attention in 1911.
NowA 2022 study of Bingham's own field notes, early maps, and Spanish colonial land documents concluded the Incas called the site Huayna Picchu, or simply Picchu. 'Machu Picchu' is the name of the taller neighboring peak, and it got attached to the ruins essentially by a mapping accident in 1911.

TaughtThe first humans crossed the Bering land bridge and reached the Americas around 13,000 years ago, at the end of the last Ice Age. These Clovis people, named for their distinctive spear points, were the continent's first inhabitants.
NowFossil human footprints at White Sands, New Mexico, dated to 21,000 to 23,000 years ago, place people in North America at the height of the last Ice Age, roughly 10,000 years earlier than the Clovis-first model allowed. First reported in 2021, the dates were independently confirmed in 2023.

Vikings reached America 'around the year 1000, maybe'
Changed in2021TaughtNorse sailors may have reached North America roughly a thousand years ago, according to the sagas, though the evidence was vague and the date uncertain.
NowNorse people were cutting timber at L'Anse aux Meadows in Newfoundland in exactly 1021 CE. The date comes from tree rings marked by a known solar storm, and it is the earliest precisely dated evidence of humans crossing the Atlantic.

Nobody knows where Stonehenge's giant stones came from
Changed in2020TaughtThe source of Stonehenge's huge upright sarsen stones is a mystery. We know the smaller bluestones came from Wales, but where the builders quarried the big ones has been debated for four centuries.
NowIn July 2020 a geochemical study matched 50 of the 52 sarsens to West Woods, a spot about 15 miles (25 km) north of the monument on the Marlborough Downs. A core drilled from Stone 58 in the 1950s, returned to England in 2018, gave researchers the chemical fingerprint to make the match.

TaughtNeanderthals were shambling, grunting cave-dwellers, incapable of art, symbolism, or real language, and they were simply outcompeted by cleverer modern humans.
NowNeanderthals made cave art, used pigment and shell ornaments, buried their dead, made tar-based adhesive, and interbred with us. Their disappearance was absorption and attrition, not a contest of intelligence.

TaughtHomo sapiens emerged roughly 200,000 years ago, in a single cradle in East Africa, and spread outward from there.
NowFossils from Jebel Irhoud in Morocco push the origin of our species back to about 300,000 years ago, and the emergence looks pan-African rather than confined to one cradle.

Richard III's grave was lost forever
Changed in2013TaughtAfter Bosworth Field in 1485, Richard III was buried at Greyfriars in Leicester, but the friary was destroyed at the Dissolution and his bones were thrown into the River Soar. The grave was gone for good.
NowHe was under a council car park. Excavation in 2012 found a skeleton in the choir of Greyfriars, and in February 2013 the University of Leicester confirmed it as Richard III through radiocarbon dating, battle wounds, scoliosis, and mitochondrial DNA matched to living descendants.

Farming came first, then villages, then temples
Changed in2011TaughtThe Neolithic sequence is fixed: agriculture produces food surplus, surplus produces settled villages, villages produce specialists, and only then can a society afford monumental religion.
NowGöbekli Tepe in southeastern Turkey is a complex of massive carved stone enclosures built around 9500 BCE by people with no pottery, no metal, no writing, and no domesticated crops. Monumental building came before farming, and may have helped drive it.

Tutankhamun was murdered by a blow to the head
Changed in2005TaughtX-rays of the boy king's mummy revealed a bone fragment inside the skull, proving he was assassinated, most likely struck from behind by a rival for the throne.
NowCT scanning in 2005 found no skull fracture and no sign of a blow. The loose bone fragments were caused after death, by Howard Carter's team removing the mummy from its coffin. He most likely died of complications from a broken leg, compounded by malaria and congenital frailty.
- Disproved
Napoleon was unusually short
Changed in1998TaughtNapoleon Bonaparte stood about five feet two, and his aggression compensated for his height, which is why we call it a Napoleon complex.
NowHe was about 5 feet 7 inches, average or slightly above for a Frenchman of his era. The confusion comes from French inches, which were longer than English ones, plus relentless British wartime caricature.
- Disproved
TaughtThe Americas were empty until Clovis hunters walked across the Bering land bridge and through an ice-free corridor about 13,000 years ago. Their distinctive fluted spear points mark the first human presence in the hemisphere.
NowPeople were in the Americas thousands of years before Clovis. Monte Verde in Chile is securely dated to about 14,500 years ago, and footprints at White Sands push human presence back to roughly 23,000 years ago.

The Dark Ages
Changed in1995TaughtAfter Rome fell, Europe entered the Dark Ages: roughly a thousand years of ignorance, stagnation, and lost knowledge, until the Renaissance switched the lights back on.
NowHistorians retired the term. The period is called the Early Middle Ages, and it produced Carolingian scholarship, the university, mechanical clocks, water and wind power, Gothic engineering, and the preservation of the classical texts the Renaissance later celebrated.

Columbus proved the Earth was round
Changed in1991TaughtEducated Europeans in 1492 believed the Earth was flat and feared sailing off the edge. Columbus defied the flat-earthers and proved them wrong.
NowEvery educated European in 1492 already knew the Earth was a sphere, and had known for roughly eighteen centuries. The argument against Columbus was that he had the planet's size badly wrong, and his critics were right.

Gutenberg invented printing
Changed in1990TaughtJohannes Gutenberg invented the printing press and movable type around 1440, and books existed only after that.
NowMovable type was invented in China by Bi Sheng around 1040, and metal movable type was used in Korea well before Gutenberg. The oldest surviving book printed with metal movable type is the Korean Jikji of 1377, 78 years before the Gutenberg Bible.

Marie Antoinette said 'let them eat cake'
Changed in1990TaughtTold that the peasants had no bread, Queen Marie Antoinette replied "let them eat cake," a remark whose cruelty helped ignite the French Revolution.
NowThere is no evidence she ever said it. The line appears in Rousseau's Confessions, written around 1765, describing an unnamed "great princess," when Marie Antoinette was a nine-year-old child in Austria who had never set foot in France.
- Disproved
The pyramids were built by slaves
Changed in1990TaughtThe Great Pyramids were raised by vast gangs of slaves driven under the whip, an image usually paired with the Exodus story.
NowThe pyramid builders were paid Egyptian laborers, organized into rotating crews, fed beef and beer, given medical care, and buried in tombs of their own beside the pyramids they built.
- Disproved
The Salem witches were burned at the stake
Changed in1990TaughtIn 1692 the Puritans of Salem burned witches at the stake on Gallows Hill.
NowNobody was burned at Salem. Nineteen people were hanged, one man was pressed to death under stones, and at least five died in jail. Burning was never a penalty for witchcraft under English law, which treated it as a felony.
- Disproved
The Titanic sank in one piece
Changed in1985TaughtThe Titanic slipped beneath the surface intact and settled on the seabed as a whole ship. The official British inquiry of 1912 concluded she went down in one piece.
NowShe broke in two at the surface. Robert Ballard's 1985 discovery of the wreck found the bow and stern lying roughly 600 meters apart, and survivor accounts that had described the ship breaking apart were vindicated after 73 years.
