    DNA analysis reveals what really killed Napoleon’s army in 1812

    The Retreat of Napoleon’s Army from Russia in 1812 by Ary SchefferIanDagnall Computing / Alamy Stock Photo
    When Napoleon’s half-million-strong army retreated from Russia in 1812, around half the men were wiped out by disease, starvation and the extreme cold. Now, state-of-the-art DNA analysis has revealed which pathogens contributed to the catastrophe.
    In the summer of 1812, Napoleon gathered as many as 600,000 troops for his invasion of Russia. However, the Tsar’s forces had abandoned Moscow and emptied the city of supplies, forcing Napoleon to retreat to the Polish border for the winter. Between October and December 1812, at least 300,000 French soldiers perished from starvation, cold and disease.

    Historical reports from survivors suggested that typhus and trench fever were the main causes of death and illness among the troops, and this was backed up by genetic testing nearly two decades ago.
    Now Nicolás Rascovan at the Pasteur Institute in Paris and his colleagues have examined DNA from the teeth of 13 of the soldiers buried in Vilnius, Lithuania, where many soldiers died during the retreat, and found no evidence of either typhus or trench fever.
    Instead, the team confirmed the presence of Salmonella enterica, which causes paratyphoid fever, and Borrelia recurrentis, which is transmitted by body lice and causes relapsing fever.

    The earlier studies relied on a technique that amplifies specific DNA sequences already suspected to be present. Rascovan and his colleagues used more advanced metagenomic analysis, which can detect the genetic material of any pathogens in a sample, making it much more comprehensive.
    “In light of our results, a reasonable scenario for the deaths of these soldiers would be a combination of fatigue, cold and several diseases, including paratyphoid fever and louse-borne relapsing fever,” write Rascovan and his colleagues in their report, which is yet to be peer-reviewed. The team declined to comment for this story.
    While not necessarily fatal, the louse-borne relapsing fever could significantly weaken an already exhausted individual, say the researchers.
    Sally Wasef at the Queensland University of Technology in Australia says the symptoms recorded in historical accounts could match several infectious diseases besides the ones suggested in the new study.

    The microbial DNA recovered from the ancient individuals was in low quantities, says Wasef. “In my view, this means the results are more suggestive than conclusive.”
    Wasef says more soldiers who died in 1812 need to be studied to confirm which diseases were present, as Rascovan and his colleagues also state in their study.
    The research highlights the potential of new tools to identify possible infectious agents in historical populations, says Wasef. She would like to see the methods used to study diseases in post-contact populations in the Americas or Australia.
    “This kind of work has strong potential to clarify the role of disease in past population declines, particularly where written records are incomplete or biased,” says Wasef.

    Ancient Siberian ice mummy is covered in ‘really special’ tattoos

    Elaborate tattoos featuring tigers, birds and a fantastical animal have been revealed on an ice mummy from more than 2000 years ago. The mummified woman was from the Pazyryk culture of Siberia, part of the wider Scythian world.
    Knowing the prevalence of tattoos during prehistory is hard, because few bodies dating back that far still have skin on them. But there are a few notable exceptions, including Ötzi “the Iceman”, who lived about 3300 BC and was preserved in ice.

    Now, Gino Caspari at the Max Planck Institute of Geoanthropology in Germany and his colleagues have examined the body of a semi-nomadic Iron Age pastoralist from the Altai mountains in Siberia, who was aged about 50 when she died in the 3rd or 4th century BC. She is one of a handful of people in that area whose deep burial chambers were encased in permafrost, which turned them into “ice mummies”, preserving their skin, but leaving it dark and desiccated.
    The tattoos were composed of creatures that seemed to be both real and fantasticalD. Riday
    “The tattoos are not visible when looking at the mummy with the naked eye,” says Caspari. So, his team used high-resolution, near-infrared photography to uncover an extraordinary array of hidden images.

    “We have herbivores being hunted by tigers and leopards, and in one case by a griffin, and on the hands, we have depictions of birds,” says Caspari. “Due to their age and the vivid art style, the Pazyryk tattoos are something really special.”
    One bird looks like a rooster, says team member Aaron Deter-Wolf at the Tennessee Division of Archaeology, but he says tattooed Pazyryk bodies are marked with a mix of realistic and fantastical animals, so it may be that the artist didn’t intend the bird to be a representation of a living creature.
    The team also learned how the tattoos were made. “Our analysis shows that the tattoos were created using the direct puncture method, as opposed to being incised or ‘stitched’ into the skin,” says Deter-Wolf.
    One of the tattoos seems to feature a roosterD. Riday
    Cross-cultural data suggests this was done using a method that is known today as hand-poking, where a needle is dipped in ink and then poked into the skin, creating an image dot by dot. Her tattoos were also made with carbon pigments, probably derived from charcoal, soot or ash.
    Those on the woman’s right forearm were more technical and detailed than those on the left, so they may have been done by different people with varying levels of skill, says Caspari. “Our study shows that tattooing was not only a widespread practice on the Eurasian steppes over 2000 years ago, but also makes it clear that it was a specialised craft which involved a lot of knowledge and practice,” he says.

    Archaeologists are unearthing the most powerful women who ever lived

    Jay Gorden
    The young man, no older than 25, had gone to the afterlife with an opulent assortment of grave goods, including an entire elephant tusk. Archaeologists who excavated his 5000-year-old remains in 2008 from a site near Seville, Spain, dubbed him the “Ivory Man” and suggested that he might have been the most important person on the Iberian peninsula in his lifetime. So it came as a shock when, 13 years later, analysis of proteins in his tooth enamel revealed that he wasn’t male at all. The Ivory Man was, in fact, the “Ivory Lady”. 
    Perhaps this re-sexing shouldn’t have come as such a surprise. Of late, the ability to probe ancient biological remains has led to the discovery of prehistoric women in all sorts of unexpected places. It turns out they have occupied roles and positions that would have confounded 20th-century researchers. Whether in the form of Stone Age women spearing bison, Neolithic ones controlling the allocation of land, or the sensational case of a Viking warrior who, like the Ivory Lady, was belatedly identified as female, the new evidence is rocking our understanding of how ancient societies viewed gender roles. 
    Nobody is suggesting that women and men were treated as equals in the ancient world, much less that it was a feminist paradise. Indeed, man-centred societies were probably the norm. But enough exceptions have come to light to suggest a breathtaking variety of social organisation. “There’s no one idea of womanhood or masculinity,” says archaeologist Rachel Pope at the University of Liverpool, UK. “Instead, there’s real variation in social norms across time and space.” Finally, we are unearthing prehistory’s powerful women. 

    Despite huge leaps in equality over the past century, today’s societies are still largely patriarchal. Archaeologists have long been taught that this status quo got its foothold when farming became widespread, starting around 10,000 years ago. Hunter-gatherer groups are generally seen as egalitarian, albeit with men and women doing different types of work. But, the idea goes, as societies became more sedentary and began generating wealth in the form of surplus food, people started to attach importance to inheritance, and rules were established for transferring wealth from fathers to sons. With wealth came male power and female oppression. Or so argued Karl Marx’s collaborator, the political theorist Friedrich Engels, in the late 1800s. “That model supported a particular political system and was based on no archaeological evidence,” says Penny Bickle, archaeologist at the University of York, UK.  
    Beginning of the patriarchy
    A rival idea, put forward in the 1960s by Lithuanian archaeologist Marija Gimbutas, suggested that Europe’s oldest farming societies were woman-centric and thrived until 5000 years ago, when herders arrived from the steppes and imposed their patriarchal world view. It has, however, proved equally unfounded. These grand narratives, which invoke a single inflection point, no longer fit the data, says Bickle. The advent of new archaeological tools – notably the ability to analyse not only ancient DNA (aDNA), but also proteins and isotopes, or variants of elements consumed as food – reveal both ideas to be overly simplistic. “We shouldn’t be writing origin stories like these,” she says. Instead, what’s emerging is a more complex picture, showing how economic and historical context powerfully shaped the way men and women lived – and that societies were capable of flipping from one system to another within centuries, if conditions changed.   

    Analysis of these societies also highlights the distinction between biological sex – including the ability to bear children – and gender, referring to our habit of assigning people distinct cultural attributes – masculine or feminine – based on their sex. Archaeologist Jennifer French at the University of Liverpool thinks that the concept of gender emerged with symbolic thinking, and that early Stone Age art and burial rites suggest the first modern humans were familiar with it, as were Neanderthals. Despite this, some researchers prefer to talk about “males” and “females” in that period, rather than “men” and “women”. “To me, it seems a little dehumanising,” she says.   
    The temple of the Egyptian ruler Hatshepsut remains a testament to one of the most powerful womenUwe Skrzypczak/imageBROKER.com/Alamy
    Nevertheless, the early Stone Age is largely a black box when it comes to gender roles. “Sexed burials with accompanying material culture, and iconographic artefacts, are either absent or rare,” says French. The tiny glimpses that archaeology and aDNA have afforded, combined with ethnographic evidence from modern or historical hunter-gatherer societies, hint that patrilocality and female exogamy were the norm. In other words, couples moved to live with the man’s family. However, because these groups tended to be small, they probably had to be adaptable, so matrilocal societies, where women stayed with their kin, may also sometimes have emerged. 
    Matrilocal societies tend to give women greater participation in communal life, says anthropologist Carol Ember at Yale University, probably because, with family around, women are less likely to be defined exclusively as wives and mothers. This is especially true if resources – importantly, land – pass through the female line. And this matrilineal system of inheritance often goes together with matrilocality. According to a hypothesis developed by Ember and her husband Melvin Ember, who was also an anthropologist, matrilocality is most likely to emerge when women are the main workers in a subsistence economy – making it preferable that daughters stay at home – and when there is no threat of war, so families have no need to keep their sons close to help defend the household. This suggests that matrilocality would have been the exception in prehistory, because intergroup violence was so common. But there are other factors favouring women-centred societies, including situations where the paternity of children is uncertain and where groups have a history of migration. 

    That covers the theory. On the ground, studying gender in prehistoric remains is complicated by the fact that how people were placed in burials may not reflect how they lived. Stable isotope analysis can help, by showing – through the detection of dietary changes – whether people died in the same place where they grew up. Genetics can help too, by revealing biological links among groups that recurred over generations and regions. Even then, interpreting the evidence can be tricky. Power maps onto patterns of post-marital residence and inheritance in different ways. Trickier still, says Pope, is that “there isn’t a demonstrable link between grave wealth and power”. 
    Grave goods for women
    A case in point is the early farming community that inhabited the 9000-year-old site of Çatalhöyük in modern Turkey. Archaeologists consider this group to have been egalitarian, in that men and women had similar diets and did similar kinds of work. But, in a new genetic study, Eren Yüncü at the Middle East Technical University in Ankara and her colleagues show that the society was matrilocal and that young women were accorded more lavish grave goods than men. This doesn’t necessarily mean that women pulled the strings at Çatalhöyük, however. “Grave goods often express the lost reproductive potential when young women die,” says archaeologist Katharina Rebay-Salisbury at the University of Vienna, Austria. 
    Exceptional though they have been, matrilocal or matrilineal societies have now been documented on every inhabited continent in the ancient world. The first humans to reach the remote islands of Oceania, around 3000 years ago, were matrilocal, according to a 2022 study led by geneticist Yue-Chen Liu at Harvard University. The earliest farming societies in Thailand probably were, too. And in 2017, geneticists detected a high-status matrilineal group that persisted for more than 300 years in Chaco Canyon, New Mexico – an important ritual and political centre in North America around the 10th century – whose modern descendants include the matrilineal Zuni and Hopi peoples.  
    Fu Hao, one of the wives of King Wu Ding of the Shang dynasty, was a military general and high priestessImaginechina Limited/Alamy
    But there is a paradox. “In the matrilocal, matrilineal societies that we have studied in the recent anthropological record, women were never political leaders,” says Ember. They had higher status and more influence than women in patrilocal, patrilineal societies, but they didn’t make the decisions. That was typically the preserve of their brothers, who were often more heavily invested in their sisters’ children than in their own. This prompts the question of what we mean by power. There are famous cases of women who took on the trappings of masculine-coded hard power, with an emphasis on physical strength and domination. The Egyptian pharaoh Hatshepsut, who reigned in the 15th century BC, sported kingly regalia, commissioned monuments and initiated at least one military campaign. The Mayan ruler Lady K’awiil Ajaw of Cobá presided over a formidable group of warriors and statesmen in the 7th century and is thought to have built a 100-kilometre road to display her authority. In general, though, women have exerted power differently from men. 
    Strength in soft power
    This is highlighted in a study by political anthropologist Paula Sabloff at the Santa Fe Institute in New Mexico, who compared the roles of royal women across eight pre-modern states. The women included queens who had acted as regents, such as Lady Fu Hao in China’s Shang dynasty more than 3000 years ago, and spouses who had deputised for their royal husbands, like the wives of Zimri-Lim, who led the Mari in what is now eastern Syria in the 18th century BC. The states spanned five continents and more than 4000 years and had different cultural norms regarding inheritance, post-marital residence and female rulers themselves. Yet, Sabloff found that in all eight, women wielded power in the same ways: by influencing policy; influencing the actions of those above and below them in rank; acting as go-betweens; and patronising clients. “That’s real power, too,” says Rebay-Salisbury. 
    Understanding this female propensity for soft power lends a different hue to some recent findings from prehistory. For instance, a man and woman found together in a grave in southern Spain, along with 30 precious metal and gemstone artefacts, are among several examples of couples who seem to have ruled jointly in the Bronze Age. They may have had equal status, while deploying different leadership skills. Or consider two kings who ruled over the Celtic Hallstatt culture of south-west Germany around 2500 years ago. Their graves are among the richest burials in European prehistory. A recent aDNA analysis reveals that they were probably a nephew and his maternal uncle, indicating that a woman linked them, even though she wasn’t buried with them.  
    Excavation of Durotriges burials found that women’s graves were more lavish than men’sBournemouth University
    But not all female power was so indirect, as new findings about another Celtic tribe make clear. The study, by geneticist Lara Cassidy at Trinity College Dublin in Ireland and her colleagues, looked at the Durotriges, who inhabited southern Britain two millennia ago – around the time that the Romans invaded. The genomic analysis of 57 individuals showed that the society was matrilocal and matrilineal, with men joining the group from outside, and that Durotrigian women went to the afterlife with more grave wealth than their male counterparts. Add to this evidence that they took up arms against the Romans and the assertion, by Roman chroniclers, that the Celtic women of Britain were fierce and liberated – most famously Boudica, who led the Iceni tribe in a revolt against the Roman invaders – and there seems little doubt that the Durotriges themselves recognised female power. 
    The line between male and female power isn’t always clear-cut, though. Also around two millennia ago, an individual was buried on one of the Scilly Isles off the south-west coast of Britain with a mirror and a sword. “Up to the Roman period, we only find mirrors in graves that we are comfortable saying were female,” says Pope. “We would tend to find swords in male graves.” The combination of the two intrigued archaeologists when they discovered the grave in 1999, but they had to wait almost a quarter of a century for aDNA analysis to show that the individual was biologically female. If her grave goods reflected her role in life, a team led by osteoarchaeologist Simon Mays of Historic England concluded, she may have been a high-ranking woman who participated in active combat. 
    Archaeological remains have revealed that female Scythian warriors weren’t just the stuff of mythologyMichael Svetbird/Alamy
    She and the Durotriges wouldn’t have been the first warrior women. There are graves of indisputably female fighters in what is now Armenia, south of the Caucasus, dating from 3000 years ago. On the steppes of Ukraine, Iron Age burials identified as Scythian include a woman interred with gold and silver treasure, arrows and her horse – hinting that the Amazons may not have been entirely mythical. Likewise, the Valkyries of Norse mythology find echoes in evidence of Viking women who charged into battle – notably the individual found in a grave at Birka, Sweden, along with weapons including a sword, axe, spear and battle knife, as well as two horses. Assumed for over a century to be a man, geneticists reassigned her in 2017. 
    As the discoveries stack up, researchers have been asking what other roles, usually attributed to men, might have been performed by women in the past – and finding that there was really no limit. In the earliest Mexican farming villages, women oversaw ceremonies involving communication with ancestors. The so-called Siberian Ice Maiden, whose tattooed body was buried in the Altai mountains of Central Asia around 2500 years ago, is thought to have been a high-ranking spiritual leader – a shaman. And women also performed shamanic rituals in pre-farming Europe. 
    Other prehistoric women, meanwhile, overturned the long-held trope of “man the hunter, woman the gatherer”. One buried with hunting implements points to the presence of female big-game hunters in the Americas 9000 years ago. Millennia later, Indigenous women acted as trackers and guides to the first European fur traders in North America. Indeed, anthropologists Sarah Lacy at the University of Delaware and Cara Ocobock at the University of Notre Dame, Indiana, make the case that women hunted throughout the Palaeolithic. In some ways, they say – notably a metabolism built for endurance – they were better adapted to the task than men.  

    Bringing all the evidence together, it is becoming clear that few roles have been off-limits to all women for all time. As new tools make fine-grained analysis possible, researchers expect more diversity to come to light. “I think it’s going to be blown wide open in the next few years,” says Cassidy. Already it is clear that, in the past, whole societies have tilted more towards gender equality than many modern ones do. Patriarchal systems damage both men and women, says Bickle, but they aren’t inevitable, and our concepts of man and woman can be reimagined.
    “Gender is not stable,” she says. “It’s subject to continuous change.”

    Ancient pots found near Pompeii contain 2500-year-old honey

    An ancient Greek bronze jar on display at the Ashmolean Museum in Oxford that was found to contain honeyAmerican Chemical Society
    The contents of an ancient Greek pot found in a shrine near Pompeii are testament to the longevity of a jar of honey.
    In 1954, a Greek burial shrine dating to around 520 BC was discovered in Paestum, Italy, about 70 kilometres south of Pompeii.
    Advertisement
    There were eight pots in the shrine containing a sticky residue, whose identity has been a mystery ever since their discovery.
    Honey was an early suspect in tests carried out on the contents of one of the pots between the 1950s and 1980s, says Luciana Carvalho at the University of Oxford.
    Three separate teams studied the residue but concluded that the jars held animal or vegetable fat contaminated with pollen and insect parts, rather than honey.

    Back then, researchers relied on much less sensitive analysis techniques, centring on solubility tests.
    Carvalho and her team began by testing the residue’s reflection of infrared light to get a sense of its bulk composition.
    The ancient honey residue from the inside of the potLuciana da Costa Carvalho
    At first, they thought the contents may be degraded beeswax, because of its outward similarity to modern beeswax and its high acidity.
    To confirm whether this was the case, the team used gas chromatography combined with mass spectrometry. But this revealed the presence of sugars including glucose and fructose, which are the main sugars found in honey.
    “We discovered a surprisingly complex mix of acids and degraded sugars,” says Carvalho. “The smoking gun for honey was finding sugars right in the heart of the residue.”
    Further analysis by Elisabete Pires, also at the University of Oxford, revealed the presence of proteins called major royal jelly proteins, which are secreted by honeybees, as well as some peptides whose closest match was from Tropilaelaps mercedesae, a parasitic mite that feeds on the larvae of honeybees.
    “This parasite is thought to have originated in Asian beehives,” says Pires, “so the fragment proteins we found in the residue are probably related to another type of parasite that already affected beehives in ancient Greece.”

    Carvalho says the cork seals in the bronze jars would have eventually broken down, letting in air and microbes. “We think that those bacteria consumed [most of] any sugar left over, producing additional acids and breakdown products,” she says. “Over time what remained of the original residue was just an acidic waxy residue at the bottom and along the walls of the jars.”
    “Confirming honey offerings in a shrine at Paestum tells us exactly how people chose to honour their deities and what ideas they held about the afterlife,” says Carvalho.

    Neanderthals were probably maggot-munchers, not hyper-carnivores

    Maggots in rotting meat could have been an important part of ancient dietsChronicle/Alamy
    Neanderthals may not have been the hyper-carnivores we thought they were. It has been claimed, based on the nitrogen isotope ratios in their bones, that our ancient relatives ate little besides meat. But these ratios can also be explained by a more balanced omnivorous diet that included a lot of maggots, as well as plant-based food.
    “Masses of maggots are these easily scoopable, collectible, nutrient-rich resource,” says Melanie Beasley at Purdue University, Indiana.
    Advertisement
    There is lots of evidence that they were routinely eaten in many societies in the past, and they are still consumed in some places today, she says. Some reindeer hunters regard certain maggots as a treat that they actively cultivate, for instance, while casu martzu, a cheese that contains live maggots, is a delicacy in Sardinia.
    Nitrogen has two stable isotopes, nitrogen-14 and nitrogen-15. The lighter isotope is more likely to be lost from living organisms than the heavy one, so, as matter moves up food chains, the ratio of nitrogen-15 to nitrogen-14 increases.
    Looking at the isotope ratios in collagen inside fossil bones can therefore tell us about the diet of those animals, with carnivores having higher ratios than herbivores. But when researchers started looking at the ratios in the bones of Neanderthals, they found something surprising: even higher ratios than those seen in lions and hyenas. “So there became this narrative that Neanderthals were these hyper-carnivores very focused on big game hunting,” says Beasley.

    But many researchers don’t buy this idea. For one thing, the bones of Homo sapiens living in prehistoric times have similar ratios – and these humans couldn’t have survived on lean meat alone. “It’s actually physically not possible,” says Beasley. “You’ll die of what early explorers called ‘rabbit starvation’.”
    The issue is that if a person’s diet is too rich in protein, their body can’t mop up all the toxic breakdown products, such as ammonia.
    There is also now plenty of direct evidence that Neanderthals did eat plants, too, for instance from studies of their dental calculus. So why were their nitrogen-15 ratios so high?
    Back in 2017, John Speth at the University of Michigan suggested it could be because Neanderthals stored meat and ate it later in a rotten state. As meat rots, gases like ammonia are given off, which should result in nitrogen-15 enrichment.
    At the time, Beasley was applying to do research at the “body farm” at the University of Tennessee where human cadavers are studied as they decay to help with crime scene analysis. She realised she could test Speth’s idea alongside the forensic research – and while she was at it, she also looked at the maggots in the bodies.
    Together with Speth and Julie Lesnik at Wayne State University, Michigan, Beasley found that nitrogen isotope ratios do increase as muscle tissue rots, but only by a modest amount. There is, however, a much bigger jump seen in the maggots of various kinds feeding on the corpses.

    These are just initial results, but they show that eating a diet very high in meat isn’t the only possible explanation for the isotope ratios in Neanderthals and ancient Homo sapiens, says Beasley. She thinks those ratios are probably due to a combination of factors – the storage, processing and cooking of meat, as well as the consumption of maggots.
    “This is an exciting new study, and I think it goes a long way toward making sense of the strange results that have come out of isotope studies in Neanderthals and other Stone Age hominins over the last couple of decades,” says Herman Pontzer at Duke University in North Carolina.
    “I find the evidence here pretty convincing, that consumption of maggots and similar larvae explains the ‘hyper-carnivore’ signal we’ve been seeing in previous fossil isotope work,” he says.
    The work also adds to the evidence that a so-called palaeo diet should include rotten meat and maggots, says Beasley. “All the people who want to go true ‘palaeo’, they need to start thinking about fermenting their meat and letting the flies access them.”

    Homo naledi’s burial practices could change what it means to be human

    Shutterstock/vyasphoto
    From a young age, the inevitability and finality of death becomes a shaping force in our lives. Indeed, it could be said that our ability to recognise our eventual demise and the grief that comes with losing those close to us are core elements of what it means to be human. They have also led to symbolic practices that have deep roots in human culture.
    We have long assumed that Homo sapiens was the only human species to have gained an awareness of the mortality of living things. But as we report in “What were ancient humans thinking when they began to bury their dead?”, archaeologists are eager to question the idea that a deep and emotional response to death is our sole preserve.
    The most challenging of their claims is that ancient humans who were very unlike us developed death rituals. But evidence is mounting that Homo naledi, an ancient human from southern Africa with a brain one-third the size of your own, buried its dead at least 245,000 years ago. Exactly why these small-brained humans may have felt compelled to develop a culture of death is unclear, but one intriguing – if speculative – idea is that they did so to help youngsters come to terms with the loss of a group member.Advertisement
    Much controversy surrounds the claim that H. naledi buried its dead, largely concerning the quality of the evidence. But since the mid-20th century, researchers have been busily narrowing the behavioural gap between our species and others, spearheaded by research showing that many animals have emotionally rich lives. Some even develop their own rituals when confronted with the death of community members. Throw in evidence that our ancestors were developing their own artistic culture at least 500,000 years ago and it is easier to accept that H. naledi was capable of developing its own burial traditions.

    Archaeologists are questioning whether a deep response to death is our sole preserve

    The provocative image of a grief-stricken H. naledi helping its young deal with loss forces as much of a rethinking about these ancient relatives as it does a reckoning of what it means to be human – and whether we are as special as we like to think.

    Triumphant images of women who climbed to new heights

    Ines Papert in Kyrgystan,Ines Papert
    Most people would find a 1200-metre wall of ice on a mountain peak intimidating. But for decorated ice climber Ines Papert, scaling the peak of Kyzyl Asker – a remote mountain on the border between China and Kyrgyzstan – was a dream. It took three attempts before she and fellow climber Luka Lindič summitted it in 2016 (pictured above), becoming the first known people to climb a precipitous route the pair dubbed “Lost in China”.
    Papert is one of more than a dozen female mountaineers whose daring expeditions to the world’s greatest peaks are featured in Mountaineering Women: Climbing through history by Joanna Croston.

    Another is mountaineer Elizabeth “Lizzie” Le Blond, photographed climbing a mountain in the Swiss Alps in 1889 in a full skirt (pictured above). Le Blond, who made 20 record-breaking ascents, also helped form the Ladies’ Alpine Club in 1907 to offer support to female mountaineers in this male-dominated sport.

    AI helps reconstruct damaged Latin inscriptions from the Roman Empire

    A Roman temple in Ankara, TurkeyPE Forsberg / Alamy Stock Photo
    Latin inscriptions from the ancient world can tell us about Roman emperors’ decrees and enslaved people’s thoughts – if we can read them. Now an artificial intelligence tool is helping historians reconstruct the often fragmentary texts. It can even accurately predict when and where in the Roman Empire a given inscription came from.
    “Studying history through inscriptions is like solving a gigantic jigsaw puzzle, only this is tens of thousands of pieces more than normal,” said Thea Sommerschield at the University of Nottingham in the UK, during a press event. “And 90 per cent of them are missing because that’s all that survived for us over the centuries.”
    Advertisement
    The AI tool developed by Sommerschield and her colleagues can predict a Latin inscription’s missing characters, while also highlighting the existence of inscriptions that are written in a similar linguistic style or refer to the same people and places. They named the tool Aeneas in honour of the mythical hero, who, according to legend, escaped the fall of Troy and became a forebear of the Romans.
    “We enable Aeneas to actually restore gaps in text where the missing length is unknown,” said Yannis Assael at Google DeepMind, a co-leader in developing Aeneas, during the press event. “This makes it a more versatile tool for historians, especially when they’re dealing with very heavily damaged materials.”
    The team trained Aeneas on the largest ever combined database of ancient Latin texts that machines can interact with, including more than 176,000 inscriptions and nearly 9000 accompanying images. This training allows Aeneas to suggest missing text. What’s more, by testing it on a subset of inscriptions of known provenance, the researchers found that Aeneas could estimate the chronological date of inscriptions to within 13 years – and even achieve 72 per cent accuracy in identifying which Roman province an inscription came from.

    “Inscriptions are one of our most important sources for understanding the lives and experiences of people living in the Roman world,” says Charlotte Tupman at the University of Exeter in the UK, who wasn’t involved in the research. “They cover a vast number of subject areas, from law, trade, military and political life to religion, death and domestic matters.”
    Such AI tools also have “high potential to be applied to the study of inscriptions from other time periods and to be adapted for use with other languages,” says Tupman.
    During testing with inscriptions that were deliberately corrupted to simulate damage, Aeneas achieved 73 per cent accuracy in restoring gaps of up to 10 Latin characters. That fell to 58 per cent accuracy when the total missing length was unknown – but the AI tool shows the the logic behind the suggestions it makes so researchers can asses the validity of the results.
    When nearly two dozen historians tested the AI tool’s ability to restore and attribute deliberately corrupted inscriptions, historians working with the AI outperformed either historians or AI alone. Historians also reported that comparative inscriptions identified by Aeneas were helpful as potential research starting points 90 per cent of the time.
    “I think it will speed up the work of anyone who works with inscriptions, and especially if you’re trying to do the equivalent of constructing wider conclusions about local or even empire-wide patterns and epigraphic habits,” says Elizabeth Meyer at the University of Virginia. “At the same time, a human brain has to look at the results to make sure that they are plausible for that time and place.”

    “Asking a general-purpose AI model to assist with tasks in ancient history often leads to unsatisfactory results,” says Chiara Cenati at the University of Vienna in Austria. “Therefore, the development of a tool specifically designed to support research in Latin epigraphy is very welcome.”
    The “dream scenario” is to enable historians “to have Aeneas at your side in a museum or at an archaeological site”, said Sommerschield at the press event. Aeneas is now freely available online.
