Overview of Unearthed! in October 2026, Part 1

This installment of Stuff You Missed in History Class’s Unearthed roundup covers a wide mix of recent historical and scientific findings. Tracy and Holly revisit several earlier episodes with updates, then move through new research on ancient disease, archaeology, animal domestication, manuscripts, and preserved texts. The common thread is how fresh evidence continues to revise long-held assumptions about the past.

Updates on Previously Covered Stories

The Parthenon’s “optical corrections” may be a myth

  • New research challenges the long-standing idea that the Parthenon’s slight curves and bulges were intentional visual corrections.
  • The study argues that straight lines would have been perceived as straight anyway, and the curvature is too subtle to have functioned as a meaningful optical trick.
  • The episode notes that the famous architectural “corrections” may be real features, but not for the reason people often claim.

Crystal Palace Park dinosaurs have been restored

  • The 19th-century dinosaur sculptures in London’s Crystal Palace Park have been fully restored.
  • With the restoration complete, they were removed from Historic England’s Heritage at Risk Register.

Mohenjo-Daro may have been unusually egalitarian

  • New work supports the idea that wealth in Mohenjo-Daro was more evenly distributed than in many early urban societies.
  • The richest homes got smaller over time while poorer households gained space.
  • The city appears to have prioritized infrastructure—drains, street planning, and public amenities—over elite monuments.

The President’s House exhibit in Philadelphia has changed again

  • The episode revisits the long-running controversy over how slavery is interpreted at the President’s House site.
  • The newer exhibit has been criticized as minimizing slavery and shifting focus away from the nine enslaved people central to the earlier memorial.
  • A request for the case to be reheard was denied by the Third Circuit.

Smithsonian backlash and public history

  • The hosts discuss a federal report attacking the Smithsonian’s National Museum of American History.
  • The National Council on Public History strongly rejected the report, calling it distorted and anti-scholarly.
  • Tracy and Holly emphasize that public history should serve education, evidence, and broad public understanding.

The Uffizi Galleries need major renovation

  • The Uffizi in Florence announced a major two-year, nearly $58 million restoration and climate-control overhaul.
  • Shortly after, a leak forced staff to move Caravaggio’s Bacchus temporarily, underscoring the need for urgent work.

Medical and Human History Finds

Smallpox in Australia: the origin is still unclear

  • Researchers reexamined how smallpox may have reached Australia.
  • The two main theories—arrival via Indonesian fishers or via the British First Fleet—both have major weaknesses.
  • The First Fleet theory is not strongly supported by evidence, and there’s no proof of deliberate infection or confirmed outbreak aboard the ships.

Australia’s Indigenous population may have been much larger

  • A related study suggests pre-colonial Indigenous Australia may have had 2 to 3 million people, far more than older estimates.
  • The implied death toll from disease, violence, and social collapse is therefore also much larger than previously believed.
  • The researchers estimate a catastrophic population loss of about 93% over the first 80 years after European arrival.

Child labor left lasting marks on Dutch skeletons

  • Skeletons of children and young adults who worked in Dutch farms and factories show clear signs of stress and injury.
  • Farm children, some only nine years old, were especially affected by heavy labor such as carrying milk and cheese molds.
  • Industrial work also caused damage, though generally less severe than agricultural labor.

Bubonic plague may have infected hunter-gatherers very early

  • Ancient DNA from Siberian burial sites suggests plague affected hunter-gatherer communities as far back as 5,000 years ago.
  • The evidence points to a serious strain of Yersinia pestis that may have spread directly from animals before later flea-based transmission evolved.
  • The findings complicate the common assumption that plague was mainly an urban disease.

A medieval leprosy hospital in Copenhagen may finally be found

  • Archaeologists uncovered what may be a burial site linked to Copenhagen’s medieval leprosy hospital.
  • About 20 bodies have been found so far.
  • If confirmed, the site could reveal more about medieval care, disease, and patient life.

Animals, Foodways, and Environmental History

Hannibal may have crossed the Alps at Col de la Traversette

  • New modeling suggests Hannibal’s army and elephants most likely crossed via Col de la Traversette, not Col du Clapier.
  • The route appears to have been the shortest and most energy-efficient option.
  • Even so, the crossing would have been brutal for the humans; the elephants seem to have fared better than the soldiers.

Pigeons may have been domesticated much earlier than thought

  • Analysis of ancient pigeon bones suggests humans were interacting closely with pigeons as early as the 13th–14th centuries BCE.
  • The birds’ diet matched human food patterns, implying either feeding by humans or close scavenging around settlements.
  • This pushes back evidence for pigeon domestication by roughly a thousand years.

Brown trout may have been deliberately transported to Norwegian mountain lakes

  • Fish traps in southern Norway suggest hunter-gatherers may have moved brown trout into mountain lakes rather than the fish arriving naturally.
  • The evidence points to intentional ecosystem management much earlier than previously assumed.
  • If correct, it shows prehistoric people were actively shaping their environments and food sources.

The “carry cow” wasn’t a cow after all

  • Bone fragments once thought to prove early domestic cattle in Ireland have been reidentified as a bear and a wild boar.
  • That removes a key piece of evidence for the early arrival of agriculture in Ireland.
  • The bear material may still prove interesting for understanding ancient Irish wildlife.

Books, Letters, Manuscripts, and Written Traces

A supposed Boston Tea Party label is actually much later

  • A Chinese-language label once thought to come from the Boston Tea Party turns out not to be from 1773 at all.
  • Linguistic analysis showed it was tied to 19th-century trade networks, likely connected to Smith, Archer & Co.
  • It still matters historically, just for a different chapter of U.S.-China commerce.

Maya glyphs name an astronomer and mathematician

  • Glyphs found in Guatemala identify Saktan Waks, apparently a Classic Maya astronomer.
  • He may be the earliest named mathematician/astronomer known in the Americas.
  • The formula relates to the movement of Venus and Mars, and the site may have functioned as a bookmaking and training workshop.

Guernsey manuscript fragments reveal medieval reading culture

  • Seventeen manuscript fragments reused in book bindings show that medieval Guernsey had a real literary culture.
  • The vernacular reading culture appears to have leaned more toward French than English.
  • One fragment of L’Histoire de Griseldis is especially notable because it adds rare evidence of that text circulating outside the French court.

Roman legal fragments at Penn Museum have been deciphered

  • Fragments acquired by Penn Museum in 1911 appear to be from a practical legal handbook for the Roman Empire.
  • The text may have been used by tax officials or legal professionals.
  • It adds new detail about law under emperors Constantius II and Julian.

Sheep pox DNA has been traced through centuries of parchment

  • Researchers reconstructed part of the history of sheep pox by analyzing parchment, teeth, and veterinary specimens.
  • The virus appears to have remained genetically stable over long periods.
  • The study could help improve future understanding and treatment of the disease.

Herculaneum scrolls may be readable using lead-based ink

  • A new method proposes using X-ray fluorescence to detect lead in the ink on carbonized Herculaneum scrolls.
  • The researchers tested the approach on mock scrolls, then used tomography and software to recover text.
  • The technique could improve “virtual unrolling” of the destroyed papyri.

A hidden book survived the destruction of the monasteries

  • A study suggests English courtier John Gage may have secretly preserved a banned manuscript of The Mirror of the Blessed Life of Jesus Christ.
  • The book had become controversial during Henry VIII’s reign despite earlier popularity.
  • Six missing pages were tracked from an archive in the UK to a matching copy at Yale’s Beinecke Library.

Listener Mail

  • A teacher wrote in about the episode on Rebecca Smith Pollard, connecting it to the ongoing “reading wars” and the shift toward the science of reading.
  • The note also included pet pictures of a dog named Kix, which the hosts clearly adored.

Main Takeaways

  • Many “settled” historical stories still change when new evidence appears.
  • Archaeology and scientific analysis are reshaping ideas about ancient cities, disease spread, animal domestication, and manuscript circulation.
  • A recurring theme is that context and methodology matter: old artifacts can be reinterpreted in radically different ways when studied with new tools.
