Maps – lost, secret and revealing

The Library of Lost Maps by James Cheshire, Professor of Geographic Information and Cartography, tells the story of the discovery of a treasure-trove at the heart of University College London. In a long-forgotten room James found thousands of maps and atlases. This abandoned archive reveals how maps have traced the contours of the world, inspiring some of the greatest scientific discoveries, as well as leading to terrible atrocities and power grabs. But maps have not always been used to navigate or reveal the world, according to a new exhibition at the British Library on Secret Maps (from 24 October 2025 to 18 January 2026). Jerry Brotton, Professor of Renaissance Studies at Queen Mary University of London, and author of Four Points of the Compass, explains how mysterious maps throughout history have been used to hide, shape and control knowledge. The biographer Jenny Uglow celebrates a different kind of mapping in her new book, A Year with Gilbert White: The First Great Nature Writer. In 1781 the country curate Gilbert White charted the world around him – from close observation of the weather, to the migration of birds to the sex lives of snails and the coming harvest – revealing a natural map of his Hampshire village.Producer: Katy Hickman Assistant Producer: Natalia Fernandez

Of the 7,000 languages estimated to exist, half will have disappeared by the end of this century. That’s the stark warning from the Director of the Endangered Languages Archive, Mandana Seyfeddinipur. The evolution of languages, and their rise and fall, is part of human history, but the speed at which this is happening today is unprecedented. Mandana will be appearing at the inaugural Voiced: The Festival for Endangered Languages at the Barbican in October. A sense of loss also runs through Sverker Sörlin’s love letter to snow. The professor of Environmental History in Stockholm writes about the infinite variety of water formulations, frozen in air, in ‘Snö: A History’ (translated by Elizabeth DeNoma), and his fears about the vanishing white landscapes of his youth.In the Arctic the transformation from frozen desert into an international waterway is gathering pace. Klaus Dodds is Professor of Geopolitics at Royal Holloway, University of London and with co-author Mia Bennett sets out the fight and the future of the Arctic in ‘Unfrozen’. While territorial contest and resource exploitation is causing tensions within the region, there is also potential for new ways of working, from Indigenous governance to subsea technologies.Producer: Katy Hickman Assistant Producer: Natalia Fernandez

The economist Yanis Varoufakis found himself in the eye of the storm as Greece’s Minister of Finance in 2015, at the height of the country’s debt crisis. Now he reflects on his political awakenings and the women who influenced him in Raise Your Soul. It’s a family story that starts in Egypt in the 1920s and traces Greece’s tumultuous century through Nazi occupation, civil war, dictatorship, socialism and economic crisis. The historian Professor Mary Vincent focuses on the Spanish Civil War and has written about fascism, political violence and its impact on the people. She sees both similarities and stark differences between the Greek and Spanish Civil Wars and ponders the question of how global politics influence what happens in nation states.As a new translation of Thucydides’s The History of the Peloponnesian War (by Robin Waterfield) is published, the classicist Professor Paul Cartledge explains why this ancient text has remained essential reading for military leaders and politicians for centuries. Thucydides’s account of the war between Athens and Sparta that began in 431 BCE depicts the devastation of civil war and reflects on the nature of political power.Producer: Katy Hickman Assistant Producer: Natalia Fernandez

The experimental cognitive psychologist and popular science writer, Steven Pinker delves into the intricacies of human interactions in his latest book, ‘When Everyone Knows That Everyone Knows...: Common Knowledge and the Science of Harmony, Hypocrisy and Outrage’. From avoiding the elephant in the room to the outing of the emperor’s new clothes, Pinker reveals the paradoxes of human behaviour. Common knowledge can bind people and communities together in a shared purpose, but Aleks Krotoski, the presenter of BBC Radio 4’s The Artificial Human and The Digital Human, journeys to the fringes of human endeavour in The Immortalists. There, Silicon Valley tech billionaires are using their wealth to focus on their own futures, attempting to disrupt and defy their own mortality.How people behave to strangers and how much they’re willing to spend to help them, is at the heart of David Edmonds’s biography of the philosopher Peter Singer. Death in a Shallow Pond considers Singer’s most famous thought experiment and his contention that we’re morally obliged to come to the aid of those less fortunate if we can. It’s a practical philosophy that has divided opinion, but also inspired a new movement of effective altruism.Producer: Katy Hickman Assistant Producer: Natalia Fernandez

At the Contains Strong Language Festival in Bradford, Tom Sutcliffe and guests explore the history and culture of the city, and nation, through its poetry and stories. From battlefields and royal courts, coalmines to curry houses Start the Week looks at the language and rhythms that have captured the country. The historian Catherine Clarke is retelling the story of the past in a new way in ‘A History of England in 25 Poems’. From the 8th century to today these verses illuminate the experiences, emotions and imaginations of those who lived through it. As the 2025 City of Culture, Bradford gets an imaginative re-making in ‘The Book of Bradford: A City in Short Fiction’, a collection filled with rich diversity and youthful energy. Its editor Saima Mir, who grew up in the city, says the stories don’t avoid the scars of past challenges, but there’s pride in a city that has overcome differences and is looking ahead.Moving on from the past is also reflected in Andrew McMillan’s debut novel, ‘Pity’, which follows three generations of a Yorkshire mining family, exploring themes of masculinity and post-industrial decline. As a prize-winning poet, McMillan will also be performing at the Contains Strong Language Festival in Bradford.Producer: Katy Hickman Assistant Producer: Natalia Fernandez

Lyse Doucet tells the history of Afghanistan in recent decades through the story of the Inter-Continental hotel, which opened in the capital in 1969. The BBC’s international correspondent stayed there frequently from the late 1980s, and she details how the Soviet occupation, civil war, US invasion and the rise, fall and rise of the Taliban have all left their mark on 'The Finest Hotel in Kabul', and the people who worked there.There’s plenty of pink champagne and fine dining in Michela Wrong’s study of the rise and fall of Mobutu Sese Seko, the charismatic dictator of Congo/ Zaire at the end of the 20th century. It’s 25 years since her biography, 'In the Footsteps of Mr Kurtz', was published, and as the Democratic Republic of Congo appears to be on the brink of another civil war, she reflects on this latest cycle of violence.There have been calls for international help in the DRC, but just how effective is military intervention in the long run? Ashleigh Percival-Borley served in Afghanistan in 2010 but had to watch from the sidelines as the US and UK abruptly pulled out a decade later, leaving a vacuum filled by the Taliban. Now, as a military historian and one of BBC Radio 4's researchers-in-residence, she’s interested in giving voice to women in war – not just as the victims, but as active participants. The New Generation Thinkers scheme, which puts research on radio, is a partnership between BBC Radio 4 and the Arts and Humanities Research Council.

The Booker prize winning novelist Arundhati Roy looks back at her foremost influences in her memoir, Mother Mary Comes To Me. While her writing and activism are shaped by early circumstances – both financial and political – at the centre is her relationship with her mother, who she describes as ‘my shelter and my storm’.The poet Sarah Howe won the TS Eliot prize for poetry for her debut collection, Loop of Jade. In her new work, Foretokens, she returns to the complex inheritance of family and language, as she tries to piece together the fragmentary, often mythical, early life of her Chinese mother, given away at birth. The academic Lea Ypi travels through the history of Ottoman aristocracy to the making of modern Albania and the early days of communism as she attempts to retrace the life of her beloved grandmother. In her new book, Indignity: A Life Reimagined, she reveals the fragility of truth, as her own memories collide with secret police reports and newly discovered photographs.Producer: Katy Hickman Assistant Producer: Natalia Fernandez

Sanctuary is an ancient idea of a place of refuge or freedom from harm. It has deep roots in the history, literature and myths of many cultures. Marina Warner’s new book Sanctuary explores travelling tales and concepts of hospitality and home - suggesting that myths, stories and works of art can be places of sanctuary too. The story of leprosy is a story of isolation and exclusion over thousands of years. In his book, Outcast, Oliver Basciano has written about his journey across the hinterlands of the world to demystify the lives of those who have been ostracised. He argues that the image we still hold onto of medieval leprosy is a nineteenth-century myth invented to justify the gross mistreatment of patients in the name of colonial, religious and economic exploitation. Churches are a spiritual home for some 200 million Christians worldwide, but they often hold a fascination and interest for the most committed atheist. A church is a place of sanctuary, but also a place where the drama of life is played out. Fergus Butler-Gallie is an Anglican priest and his new book Twelve Churches explores the history of Christianity through the places worshippers have built.

We think we know what a genius is: a tortured poet; rebellious scientist; monstrous artist; or a tech disruptor. You can tell what a society values by who it labels as a genius says Helen Lewis in her new book, The Genius Myth: The Dangerous Allure of Rebels, Monsters and Rule-Breakers. From Leonardo da Vinci to Elon Musk, she asks if the modern idea of genius, as a class of special people, is distorting our view of the world.With ten platinum albums Tupac Shakur was one of the stars of hip hop music when he was murdered at the age of 25. His music was very influential and his name is also associated with the legacy of Black Panther politics. In Words for My Comrades: A Political Biography of Tupac Shakur, Dean Van Nguyen argues that while much of the energy of the Black political movement was absorbed by the commercial music culture of the 1990s – Tupac’s contribution lives on today. Gertrude Stein was considered a genius by some, a charlatan by others. She posed for Picasso’s portrait; hosted Matisse and Hemingway in Bohemian Paris; and she dazzled American crowds on her sell-out tour for her sensational Autobiography of Alice B Toklas, a version of the relationship with her partner. Francesca Wade’s new book Gertrude Stein: An Afterlife, explores the creation of the Stein myth. Presenter: Adam Rutherford Producer: Ruth Watts

There is a parallel world which operates under different rules and benefits those with money and power. That’s the argument made by the journalist Atossa Araxia Abrahamian in her new book The Hidden Globe: How Wealth Hacks the world. She traces the rise of a freeports, charter cities and offshore havens. Danny Dorling contends that we’re not very good at spotting the real crises we face today. In The Next Crisis: What We Think About the Future, he explains why the most urgent global crises are rarely the ones that hit the headlines. From inequality, immigration and international conflicts to climate change, pandemics and tsunamis, he challenges our assumptions about the threats we face and how we should think about our uncertain future.It is time to reclaim online spaces, says Adele Zeynep Walton. In her new book Logging Off: The Human Cost of Our Digital World she explores how the price of the connections and conveniences of online life has been the mental health of a generation. She says that social media platforms and digital technology are making us vulnerable and it is time these spaces were governed and regulated.Presenter: Tom Sutcliffe Producer: Ruth Watts
