With its multiple narrators, superb and complex characterisation, the influence of Don Quixote de la Mancha has been acknowledged by great writers through the ages as a masterpiece, and hailed as one of the most important novels in the history of literature.On the surface the novel appears to be a comedy – of situation, of language and of character – but its author Cervantes succeeds in making Don Quixote so much more than a series of slapstick episodes. It was written during a particularly turbulent time in Spanish politics, when both Jews and Muslims were expelled from the Iberian peninsula, and this finds its way into the novel. Bridget Kendall explores the tale of the self-styled knight Don Quixote and his sidekick Sancho Panza with Cervantes experts Ruth Fine, the Salomon and Victoria Cohen Professor in Iberian and Latin American Studies at the Hebrew University of Jerusalem; Carolyn Nadeau, the Byron S. Tucci Professor of Hispanic Studies at Illinois Wesleyan University; and Edwin Williamson, the King Alfonso XIII Professor Emeritus of Spanish Studies at the University of Oxford.(Photo: Cervantes Monument in Madrid, Spain showing Don Quixote and Sancho Panza.

They’re slimy and slippery. They’re part of the green film you see on garden ponds. They can clump together and wash up on the shores of beautiful beaches. A lot of them are invisible to the naked eye. These underappreciated organisms called algae are indispensable to the presence of life on earth but not all is straightforward about them. They can be single celled or multi cellular. They can be ugly and slimy or sometimes beautiful: indeed are even a tourist attraction. They may be found in the sea or on land. They can be life-creating and yet life-destroying and toxic in excess. So perhaps it’s time we paid more attention to algae and their evolution. Rajan Datar is joined by Ruth Kassinger, author of Slime: How algae created us, plague us and just might save us; Dr Brenda Soler-Figueroa, a marine scientist at the Smithsonian Environmental Research Centre; Dr Gothamie Weerakoon Senior Curator of Lichens and Slime Moulds at the Natural History Museum of London and author of Fascinating Lichens of Sri Lanka; and Stefan Bengtson, emeritus professor at the Swedish Museum of Natural History.(Photo: Volvox algae colonies, spherical forms outlined by biflagellate cells interconnected by cytoplasmic bridges.

The Goths were a Germanic tribe infamous for their brief sack of Rome in 410 AD but their cultural and political influence was felt throughout Europe for centuries. They re-shaped the Balkans, preserved the Roman way of life in Italy and presided over a cultural flourishing in Spain. But how, many centuries after their demise, did they come to give their name to an important architectural style in medieval Europe and, in the 20th century, to a subculture popular all over the world?Bridget Kendall talks all things Gothic with David Gwynn, historian at Royal Holloway, University of London, and author of Goths, the Lost Civilisation. Also on the panel are Janina Ramirez, a cultural historian, broadcaster and author who focuses on the Middle Ages, based at the University of Oxford, and Mischa Meier, professor of ancient history at the University of Tubingen in Germany.

The 1821 Greek war for independence from the Ottoman empire became an inspiration for people all over Europe who wanted to dismantle the old multi-ethnic empires. But it is less well known that a number of women played key roles in the uprising. In this programme, Bridget Kendall and guests focus on Laskarina Bouboulina, perhaps the best known of Greek women freedom fighters. For the last two centuries, Bouboulina's deeds as as a brave sea captain and a generous financier of the uprising have enthralled people in Greece and elsewhere but how many of these stories are based in fact? And what is the significance of Bouboulina today?To find out Bridget is joined by: Dr. Margarite Poulos, a historian of modern Greece from Western Sydney University whose book Arms and the Woman surveys the role of Greek women in the country's military struggles; Dr. April Kalogeropoulos Householder from University of Maryland, Baltimore County, who has not only written about Laskarina Bouboulina but also made a documentary film about her; and Pavlos Demertzis-Bouboulis, who is a descendant of Bouboulina as well as the director of a museum dedicated to her on the island of Spetses.[Image: Portrait of Laskarina Bouboulina, 1830, by Adam Friedel.

For someone who was largely self-taught, Mary Somerville's rise to renown in the male-dominated world of science was quite remarkable. Although women were barred from being members of the learned societies where knowledge was shared in the early 19th-Century, Somerville found alternative ways to become one of the most respected figures in maths and science of her day.Scottish-born Somerville played a crucial role in communicating the latest findings in science through a series of successful books. She regretted never making any original discoveries herself however, so does her experience suggest we should re-evaluate the role of originality in science?Bridget Kendall is joined by Jim Secord, emeritus professor of History and Philosophy of Science at the University of Cambridge, who has edited the works of Mary Somerville; Dr Brigitte Stenhouse, lecturer in the History of Mathematics at the University of Oxford whose doctoral thesis looked at the mathematical work of Mary Somerville; and Ruth Boreham, former project curator at the National Library of Scotland, who is writing a biography of Mary Somerville.Producer: Fiona Clampin (Photo: Royal Bank of Scotland £10 note featuring Mary Somerville)

One of the earliest Cold War conflicts was a 12-year guerrilla war commonly known as the Malayan Emergency and fought from 1948 in the jungles of what is now Malaysia. This communist insurgency was fuelled not only by ideology but also by the desire for Malayan independence from British colonial rule. There have been a number of books and documentaries devoted to the subject but relatively few in English capture the experiences of the Chinese community in Malaya that was at the centre of the Emergency.Rajan Datar is joined by three guests, all with family links to the Emergency: Sim Chi Yin, a photographer and artist from Singapore whose book She Never Rode that Trishaw Again tells the story of her grandmother widowed during the war in Malaya; Show Ying Xin, a postdoctoral fellow at the at the Australian National University’s Malaysia Institute in Canberra; and Rachel Leow, Associate Professor in Modern East Asian History at the University of Cambridge and author of Taming Babel: Language in the Making of Malaysia.[Photo: Malayan police officers keeping watch from the Pengkalan police station in 1950.

The Devils, The Possessed, or Demons, as it’s also known in translation, is Fyodor Dostoevsky’s most political novel but it’s also his bleakest and funniest. It’s a hundred and fifty years since its publication and two hundred years since its author’s birth. The novel tells the story of a group of young revolutionaries who run riot in a small provincial town in Russia, all under the indulgent eye of their elders, the liberal and progressively minded elite. It is a grim prophecy of totalitarian rule in the 20th century in what is a penetrating psychological study of the human consequences of extreme philosophical ideas.Joining Bridget Kendall to discuss Dostoevsky and his novel The Devils or Demons, is Tatyana Kovalevskaya, Professor at the Russian State University for the Humanities in Moscow and the author of the bilingual edition Fyodor Dostoevsky on the Dignity of the Human Person; Carol Apollonio, Professor of the Practice of Slavic and Eurasian Studies at Duke University in the United States and President of the International Dostoevsky Society; and Dr Sarah Hudspith, Associate Professor in Russian at the University of Leeds, and author of Dostoevsky and the idea of Russianness.

If you had to name the innovations that have transformed human civilisation, you might suggest the printing press or the Internet, but the humble pair of spectacles has also revolutionised the way many of us experience the world. It's said that an astonishing three quarters of those in the US use glasses or contact lenses to correct their vision. And the World Health Organisation estimates that more than a billion people in low-and-middle income countries are living with sight problems that could be corrected by the right pair of specs. But how and when were glasses first invented? What impact have they had on societal development? And what are some of the ways we've stigmatised, or even elevated, people who wear them?Joining Rajan Datar to explore the history of spectacles are Travis Elborough, a historian of popular culture from the UK. He’s recently published a book called Through The Looking Glasses: The Spectacular Life of Spectacles; Stefana Sabin, a German literary scholar and the author of In The Blink of an Eye – A Cultural History of Spectacles – which has just been translated into English; and Professor Kovin Naidoo, Senior Vice President in social impact at the French-based optics company, Essilor. He’s also former CEO of the Brien Holden Vision Institute. He originally trained as an optometrist in his native South Africa.[Image: Hugh of Saint-Cher, 1351-1352.

Whether photographed in a coffin or depicted on an Art Nouveau poster, the French actor Sarah Bernhardt knew exactly how to get maximum publicity. Although her first outings on the stage were unremarkable, she refined her skills and rose to become the leading actor of her generation and a world-famous name. Her life off-stage was a further source of endless fascination, her eccentric and occasionally arrogant behaviour only adding to her allure. Her critics saw her as manipulative and hackneyed. For her admirers, seeing Bernhardt ‘die’ on stage was a moment to be treasured for ever.Bridget Kendall charts Sarah Bernhardt’s life and career with John Stokes, emeritus professor of modern British literature at King’s College London and author of The French Actress and Her English Audience; Victoria Duckett, senior lecturer in screen and design at Deakin University in Melbourne and the author of Seeing Sarah Bernhardt: Performance and Silent Film; and Sharon Marcus, the Orlando Harriman professor of English and comparative literature at Columbia University. Her 2019 book The Drama of Celebrity is an exploration of the processes that propel a figure such as Sarah Bernhardt to global fame.Producer: Fiona Clampin(Photo: Posters showing Sarah Bernhardt as Camille in La Dame Aux Camelias (Lady of the Camellias) by Alphonse Mucha.

We seem to have an almost insatiable appetite for the glitter and sparkle of diamonds. Yet transforming these stones into jewels fit for princesses and film stars involves a long chain of production and distribution. And the diamond industry has long been bound up with a much darker side: the exploitation of workers, environmental damage, all-powerful monopolies and violent mafias, not to mention the so-called Blood Diamonds used to finance armed conflict. So how is the industry trying to clean up its image and regulate the trade?Joining Bridget Kendall to discuss the history of the diamond trade are:Dr. Lansana Gberie, former coordinator for the UN Security Council Panel of Experts on Liberia. He is the author of A Dirty War in West Africa: The RUF and the Destruction of Sierra Leone. He’s also Sierra Leone’s current Permanent Representative to the UN in Geneva and the Sierra Leonean Ambassador to Switzerland - though his contributions to this programme are in a personal capacity.Ian Smillie, founder of the Diamond Development Initiative, now DDI at Resolve, an organisation which works to improve conditions for small-scale miners. He is the author of several books, including Blood on the Stone: Greed, Corruption and War in the Global Diamond Trade. He is based in Canada.Dr. Tijl Vanneste, researcher at the Portuguese Institute of International Relations at Nova University in Lisbon. He is the author of Blood, Sweat and Earth: The Struggle for Control over the World's Diamonds Throughout History.[Image: Examining a gem diamond in Antwerp, Belgium; Credit: Paul O'Driscoll/Getty Images]

Eva Peron rose from a childhood of poverty to become one of the most powerful figures in Latin America. An illegitimate small town girl, she smashed class and gender barriers to become Argentina’s controversial First Lady. Loved and loathed, Rajan Datar discusses her life, work and remarkable afterlife with biographer Jill Hedges, historian Ranaan Rein, and cultural theorist Claudia Soria.[Photo: Eva Peron in 1951.

It’s one of the most popular dishes in the world today, but the story of sushi can be traced back more than 2,000 years. The earliest records document a preserved fish dish in ancient China and it later became a medieval luxury in Japan, before evolving into a variety of different regional styles and recipes. Today, thanks to waves of migration from Japan, there is a veritable smorgasbord of international varieties… California roll, anyone? Joining Rajan Datar to discuss the history of sushi are James Farrer, Professor of Sociology and Director of the Graduate Programme in Global Studies at Sophia University in Tokyo. He is the author of Globalisation and Asian Cuisines; Eric C. Rath is Professor of Premodern Japanese History at the University of Kansas in the US. He’s the author of Oishii: The History of Sushi; and Michelin-starred Japanese sushi master, Endo Kazutoshi, who is head chef at The Rotunda in London.Presenter: Rajan Datar[Image: Young woman eating sushi; Credit: Getty Images]

The American writer Toni Morrison once said, “If there’s a book that you want to read, but it hasn’t been written yet, then you must write it.” It was an urge which in her case yielded a rich array of novels, children’s books, plays and essays. Toni Morrison stands tall, as the first black woman of any nationality to be awarded the Nobel Prize for Literature. Celebrated for her masterpiece Beloved, she remains a towering figure, one of the most well-known and oft-taught authors of our age. Since her death in August 2019, many have been reassessing her multiple legacies: as a novelist, cultural critic, and editor.Joining Bridget Kendall to explore the life, work and impact of Toni Morrison are Dana Williams, Professor of African American Literature at Howard University in Washington DC and current President of the Toni Morrison Society; Janis A. Mayes, Emerita professor of African American Studies at Syracuse University, US; and Aretha Phiri, Associate Professor at Rhodes University in Grahamstown / Makhanda, South Africa.Produced by Jo Impey for BBC World Service Additional research by Tessa Roynon[Photo: Toni Morrison in Chicago, Illinois in 2010.

Hidden from view, complex to understand and often controversial, algorithms are at the heart of computer coding that underpins modern society. Every time we search the internet, every time we pay by credit card, even the romantic partners suggested to us by online dating sites – they’re all powered by algorithms. And their reach is growing all the time, as some societies use them to automate decisions regarding criminal justice, mortgage applications and job recruitment.The history of algorithms is surprisingly ancient, stretching back to the Babylonian empire where large societies required a systematic way to count and order different aspects of citizens’ lives. Today some people are questioning their use, as some algorithms have been shown to replicate bias and there are fears that algorithms have the potential to undermine democracy.Bridget Kendall is joined by Ramesh Srinivasan, Professor in the Department of Information Studies at the University of California Los Angeles and the author of Beyond the Valley: How Innovators around the World are Overcoming Inequality and Creating the Technologies of Tomorrow; the French computational scientist, consultant and entrepreneur Aurélie Jean, who’s published From the Other Side of the Machine: A scientist’s journey in the land of algorithms; and Ian Stewart, Emeritus Professor of Mathematics at Warwick University who’s written more than 120 books on aspects of mathematics and science.Produced by Fiona Clampin for the BBC World Service[Image: Digital data and binary code.

Whether it be a kerrang, a chop, a blistering solo, some finger picking or a subtle flange, the electric guitar is one of the defining sounds of the 20th century. Without it – and its constant companion, the amplifier - popular culture would be unrecognisable today: no big gigs, no stadium concerts. And almost certainly no rock music. But why was it needed and how was it created? Who were the pioneers of the technology and who were the early-adopting exponents?Rajan Datar and his three guest experts delve into the roots of this iconic instrument. Monica Smith is Head of Exhibitions and Interpretation for the Smithsonian's Lemelson Center for the Study of Invention and Innovation. Among the many projects she has curated at the museum is From Frying Pan to Flying V: The Rise of the Electric Guitar. Paul Atkinson is professor of Design and Design History at Sheffield Hallam university and the author of Amplified: A Design History of the Electric Guitar. HP Newquist is the founder of the National Guitar Museum in the United States. He has written numerous books on the guitar and its history, and was the editor-in-chief of Guitar Magazine.[Image: electric guitars. Credit: ilbusca/Getty Images]

It’s a hundred years since the infamous premiere of Luigi Pirandello’s experimental play Six Characters in Search of an Author, when an enraged Rome theatre audience yelled abuse at the Italian playwright and chased him out of the theatre. Since then, the play has gained iconic status as a piece of theatre which helped move Western culture into modernity. But what of the author of this play? He was a complex figure who found inspiration from his wife’s madness as well as the actors he worked with, and he formed an unlikely association with the Italian Fascist Prime Minister Benito Mussolini which still intrigues theatre critics and academics to this day. Joining Rajan Datar to discuss Luigi Pirandello and his work are Guido Bonsaver, Professor in Italian Cultural history at the University of Oxford; Dr Enza de Francisci, lecturer in Translation studies at the University of Glasgow, who specialises in Pirandello’s Sicilian identity and his portrayal of women, and is the author of A 'New' Woman in Verga and Pirandello: From Page to Stage; and Patricia Gaborik, who teaches theatre history at the University of Calabria in Italy, and has studied Pirandello’s relationship with the Italian Fascist leader Mussolini and is the author of Mussolini’s Theatre: Fascist Experiments in Art and Politics. The readings were by Marco Gambino.Produced by Anne Khazam for the BBC World Service.

With three separate missions exploring the Red Planet in 2021, Mars is once again under the spotlight. But to tell the truth, it’s never been away. Mars has fascinated people for centuries with its seemingly curious motion in the night sky, its red colour and the eternal question as to whether it may or may not harbour life, past or present.Since the 1960s, robotic exploration of Mars has provided us with evidence that it may have had periods where it was once a warm and wet planet. That’s in contrast to the arid, cold celestial object we know today. The harsh Martian atmosphere presents challenges for anyone hoping to land humans on the planet. But nevertheless, the next few decades could potentially see either a private commercial operator, a national space agency or an international partnership make history with the planet’s first human exploration. Some have even argued that’s a first step to ‘terraforming’ or populating Mars in the future.Bridget Kendall is joined by Michael Meyer, the lead scientist for NASA’s Mars Exploration Programme; Sarah Stewart Johnson, Associate Professor of Planetary Science at Georgetown University and author of The Sirens of Mars; Jorge Vago, the Scientist for Mars Missions at the European Space Agency, and curator Matthew Shindell from the Smithsonian National Air and Space Museum in Washington, DC.

The writer Amir Hamza is a national hero in Indonesia celebrated for both his poetry and his role in the development of the country’s national language. Hamza was an emotional man who struggled with thwarted love and inner conflict and created a beguilingly intense body of work. His poetry paid homage to Malay literary tradition infused with Islamic mysticism but also reflected new ideas springing up in the artistic circles in Java where he worked in the 1930s. Towards the end of that decade events conspired to enforce his return to the family home in Sumatra and ultimately led to his becoming a tragic victim of brutal retribution during Indonesia’s transition to independence. Rajan Datar is joined by Ayu Utami, an award-winning Indonesian novelist, playwright and broadcaster; Ben Murtagh, Reader in Indonesian and Malay at SOAS, University of London, and managing editor of the journal Indonesia and the Malay World; and Taufiq Hanafi, an Indonesian literary scholar currently at the Royal Netherlands Institute of Southeast Asian and Caribbean Studies in Leiden. The reader is Sallehuddin Abdullah-Sani.[Photo: Amir Hamzah]

David Lewis was of one of the most remarkable nautical explorers of modern times. In the mid-1960s, he took his wife and two small daughters - who were less than five years old - on a sailing trip around the world in a small catamaran. What is more, for one part of the journey, he rejected standard 20th-Century navigational equipment and relied on much older methods of finding his way across the Pacific. In fact, it was his lifelong goal to prove that ancient seafaring methods were still valuable and his research helped revive ancient Polynesian navigation methods. In his more than eventful life, he also wrote a dozen books, practised as a GP in London’s East End and tackled many unclimbed peaks as a mountaineer. And he undertook hazardous trips to the Antarctic including one in which he was presumed dead.Rajan Datar is joined by David’s son Barry, who is also an accomplished sailor and who accompanied David on some of his seminal voyages; Dr. Christina Thompson, the editor of Harvard Review and the author of Sea People: The Puzzle of Polynesia; and Ben Lowings, a yachtsman, BBC journalist and the author of David Lewis's biography entitled The Dolphin.[Photo: David Lewis sets out on his 1972 trip to the Antarctic in his 32-foot sloop Ice Bird.

Patricia Highsmith was one of the most successful suspense writers of the 20th century. Known especially for her novels The Talented Mr. Ripley, Carol and Strangers on a Train, she created complex and alluring characters, capable of terrible things and at the same time deeply human. Yet for much of her life, Highsmith herself remained an enigmatic figure, often seen as eccentric, troubled and difficult. But she had a circle of close friends who were loyal to the end.Presenter Bridget Kendall is joined by Andrew Wilson, author of the first biography of Highsmith, and Vivien De Bernardi, a close friend of Highsmith's during her later years in Switzerland.Produced by Jo Impey for BBC World ServiceImage: Patricia Highsmith at her home in France, 1976 Image credit: Derek Hudson, Getty Images

Over a thousand years ago in the city of Bukhara in modern-day Uzbekistan, a young man was gaining a reputation for his great medical knowledge. His name was Ibn Sina and he was to go on to become one of the most influential physicians and philosophers not just in the Islamic world, but also in the West, where his writings were translated into Latin under the name Avicenna. For over 500 years, his five-volume Canon of Medicine was the most important medical reference book in the world.Joining Bridget Kendall to discuss Ibn Sina are: Nader El-Bizri, Professor of Philosophy and Civilisation Studies at the American University in Beirut; Peter E. Pormann, Professor of Classics and Graeco-Arabic Studies at the University of Manchester; and Emann Allebban, Assistant Professor in Philosophy at Providence College in Rhode Island in the US.Image: 14th century illuminated portrait of Avicenna or Ibn Sina, Biblioteca Nazionale Florence, Italy (Photo by Leemage/Corbis via Getty Images)

Completed in 1914, the Panama Canal has long been regarded as a triumph of American ingenuity, a conquest over nature that helped secure the United States’ position as a world power. Taking ten years to build, it opened up new trading routes between East and West by providing a vital waterway between the Atlantic and Pacific oceans. But what was the real story behind this challenging engineering project? How were the Panamanians affected? Who were the tens of thousands of workers who built the canal? And what was the environmental impact of work that literally cut through a mountain and redirected two oceans? And with climate change, will the Panama Canal be such a vital waterway in the future? Joining Bridget Kendall, is the Panamanian academic Dr Marixa Lasso, author of “Erased: The Untold Story of the Panama Canal”, the first major book on the Canal from the Panamanian point of view; Julie Greene, Professor of History at the University of Maryland, and the author of “The Canal Builders: Making America’s Empire at the Panama Canal”, and Paul Sutter, Professor of Environmental History at the University of Colorado, Boulder, and author of a forthcoming book on the impact of US public health measures during the construction of the Panama Canal.Producer: Anne Khazam(Image: A painting depicting the S.S.

Ida Pfeiffer's desire to see the world was like many childhood fantasies - destined to remain just that. And yet at the age of 44 once her sons had reached adulthood, she set off from her home in Vienna on a series of journeys that no woman of her time or background had contemplated. Beginning with a trip to the Middle East, Pfeiffer travelled mostly alone, documenting her voyages and collecting specimens that she later sold to help finance her adventures abroad. Budget travel was her mantra, as she was not a wealthy aristocrat like many travellers of that time. On her journeys Pfeiffer was attacked, kidnapped, robbed and almost drowned. She met head-hunters and endured extreme conditions to pursue her dream. Defying all convention, Pfeiffer became celebrated as the most travelled woman on the planet, circumnavigating the globe twice. But despite her trailblazing attitude, she was no feminist, believing that women should be either professionals or home-builders, not both.Rajan Datar discusses the life of this most unlikely traveller with the social and cultural anthropologist Hiltgund Jehle; Ulrike Brisson, whose research has focused on 19th and early 20th-Century European women's travel writing; and John van Wyhe, senior lecturer in the department of biological sciences at Tembusu College in Singapore, and author of Wanderlust: The Amazing Ida Pfeiffer, the first female tourist.Producer: Fiona Clampin(Image: Portrait of the Austrian traveller Ida Pfeiffer (1797-1858), from Il Giro del mondo (World Tour), Journal of geography, travel and costumes, Volume XVII, Issue 8, February 23, 1873.

How did we get from not having any reliable way of predicting the weather just 150 years ago, to today's accurate, tailor-made forecasts for places as small as a village? Bridget Kendall and guests trace the history of meteorology, from its first steps as an aid to quicker trans-Atlantic shipping to the latest methods which can help anticipate weather events as short-lived as a tornado.Bridget is joined by Kristine Harper, a former US Navy forecaster and now a history professor at Florida State University; Peter Gibbs who started out as a meteorologist with the British Antarctic Survey and the UK's Met Office before becoming one of the best known weather forecasters on BBC radio and television; and Peter Moore, a writer and historian with a particular interest in weather discoveries of the 19th century.Photo: A hurricane is seen from the International Space Station.

A young immigrant to the USA who started out working in a draper's shop, Emile Berliner ended up paving the way for the world of recordings and home entertainment that we delight in today. But even before he got to work on his recording machine - which he would later call the gramophone - Berliner made a major contribution to another piece of technology that's very familiar to us today: the telephone. And not content with all these achievements, he also promoted the pasteurisation of milk, financed a major scholarship for women to pursue academic research and tried to develop a working helicopter. So how did Berliner come up with these ideas? Why was he at one point prevented from selling his gramophones and records? And why is his name less well known today than those of his contemporaries Nikola Tesla, Thomas Edison and Alexander Graham Bell?Bridget Kendall is joined by three Berliner experts: Dr. Anja Borck, director of the Musee des ondes Emile Berliner in Montreal; Sam Brylawski, former head of recorded sound at the Library of Congress in Washington which houses an extensive Berliner archive; and David Giovannoni, a historian of recorded sound and the co-author of E. Berliner's Gramophone - a study of the American disc industry from 1892 to 1900.[Image: Berliner gramophone, 1890. Credit: Science & Society Picture Library/SSPL/Getty Images]

Have you ever sat against the trunk of a large old tree, looked up into its canopy and wondered what it’s seen in its lifetime? There are many species of tree that survive well beyond a human lifespan, for hundreds of years, and some that can live far longer than that, spanning millennia. What can we learn from large old trees around the world? How do they influence the environment? And how can we preserve them for future generations?Joining Bridget Kendall to discuss ancient trees are Peter Crane, former director of the Royal Botanic Gardens at Kew in London; Valerie Trouet, Professor at the Laboratory of Tree-Ring Research at the University of Arizona in the US; and conservation biologist, Michael Gaige.Produced by Jo Impey for BBC World ServiceImage: A Bristlecone Pine, one of the oldest living organisms on earthImage credit: Piriya Photography / Getty Images

The Wizard of Oz is best known as one of the most watched films of all time, or as one of its many re-incarnations, such as the hugely successful Broadway musical Wicked or the Soviet, The Wizard of the Emerald City. But fewer people nowadays may be aware of the original book by the American writer L. Frank Baum that inspired these stories about a young girl who travels through a magic land in the company of a talking scarecrow, a tin man and a fearful lion. While he was a controversial figure, it was L. Frank Baum’s ideas about social justice and rights for women which pervade not just The Wizard of Oz but also its sequels, and explain why this story in its many forms has inspired many minority groups, from the African American to the LGBT communities. Joining Bridget Kendall is Michael Patrick Hearn, considered to be the world’s leading Oz scholar, and author of The Annotated Wizard of Oz; Dr Sally Roesch Wagner, who specialises in the feminist aspects of The Wizard of Oz including the influence of Frank Baum’s mother-in-law, the women’s rights campaigner, Matilda Joslyn Gage, and the Russian writer Olga Zilberbourg who has studied the very popular Soviet version of the story.Produced by Anne Khazam for the BBC World Service.[Image: Publicity still from the 1939 film The Wizard of Oz.

The practice of hunting with birds of prey is thought to stretch back thousands of years. In early nomadic societies, falconry was used to hunt animals to provide food and clothing in places such as the steppes of Central Asia. As the practice spread, falconry evolved into a pastime that attracted the elite of European society, reflected in the extensive iconography of noblemen and women and their falcons. Today falconry is found in more than 90 countries around the world.At its core remains the importance of the relationship between falconer and the bird of prey, a bond unlike any other between man and beast. But although falconry has been classed as intangible cultural heritage by UNESCO, there are challenges to its survival. And some argue that falconry itself is exploitative.Rajan Datar is joined by the president of the International Association for Falconry, His Excellency Majid al-Mansouri; Adrian Lombard, Chair of the South African Falconry Association; art historian Anne-Lise Tropato, the first Falconry Research Fellow at New York University Abu Dhabi, and social anthropologist Sara Asu Schroer who's researched the relationships between falconers and birds of prey through fieldwork in Britain and Europe.Produced by Fiona Clampin for the BBC World Service[Image: Emirati Ali Mansouri trains a falcon in the Liwa desert.

Aramaic is a language that for some three thousand years facilitated the exchange of ideas across large tracts of the Middle East and Asia. In its heyday it was the main official and written language across the Neo-Assyrian and Achaemenid empires. It was the language in which several sections of the Old Testament Bible were written. A Galilean dialect of Aramaic was probably the language Jesus spoke. Different dialects of Aramaic still exist today but numbers of speakers are dwindling and there are fears that it could die out.So what is the story of Aramaic? Why did it become so influential and then go into decline? And how much has it changed over its long history?Bridget Kendall is joined by three distinguished scholars of Aramaic: Professor Holger Gzella from Ludwig-Maximilians University in Munich is the author of numerous publications on Aramaic as well as being an expert on other Old Testament languages.Professor Alison Salvesen from Oxford University works on ancient interpretations of the Hebrew Bible including its Aramaic versions. She is also an authority on Jacob of Edessa, a leading religious scholar who wrote in one of the many variants of Aramaic.Dr. Alinda Damsma teaches Biblical Hebrew at University College London and Aramaic at the Ecole Rabbinique in Paris. She studies medieval Aramaic dialects, especially in Jewish mystical literature, and has also done field research on the current use of the language.[Image: Aramaic script on a stone slab from Palmyra, Syria.

The discovery of X-rays by the German scientist Wilhelm Roentgen in 1895 was nothing short of ground-breaking, opening up a new era in medicine. For the first time, doctors could see inside the human body without the need for surgery, and diagnose many more living patients. X-rays had major implications for physics as well, allowing scientists to study the structure and arrangement of molecules. Within wider society, they inspired artists to explore what these new rays could tell us about the representation of reality. It wasn’t long before X-rays were being used to scan baggage, in airport security and even in shoe shops to measure feet before exposure to radiation was properly understood. Huge strides in X-ray technology have given us the type of modern scans that are used today to detect conditions such as cancer. Joining Bridget Kendall are Drs Adrian Thomas and Arpan Banerjee, both radiologists who’ve collaborated on publications about the history of X-rays, and artist Susan Aldworth who’s used brain scans in her work to investigate the nature of identity.Produced by Fiona Clampin for the BBC World Service[Image: Cogito Ergo Sum 3.

Over five hundred years ago, dismissed diplomat Niccolò Machiavelli produced his most famous work, The Prince. Written on the fringes of the Italian city of Florence, the book has long been read as a priceless guide to power and what holding it truly involves. But who was the man behind the work? Why did he claim that a leader must be prepared to act immorally? And why did the name of this one-time political insider become a byword for cunning and sinister strategy?Rajan Datar explores the life and impact of Machiavelli’s The Prince with writer and scholar Erica Benner, historian professor Quentin Skinner, and journalist and novelist David Ignatius.[Image: Circa 1499, Niccolò Machiavelli.

The motor car is a feature of contemporary life the world over but when and where did motor vehicles begin? How did we get from the slow, noisy, dangerous, early vehicles of the 19th century to the swish, sleek, practical cars of today? Why did the early electric vehicle – so popular early on and the first car to go faster than a hundred kilometres an hour - suddenly fall out of favour? And who were the early engineers whose major contributions to car design deserve to be better known? These are some of the questions that Bridget Kendall asks three automotive experts: writer and broadcaster Giles Chapman is the award-winning author of 55 books on car history, culture and design; Larry Edsall also has many automotive books to his name; he has written about cars for many American newspapers and is founding editor at ClassicCars.com; and Gundula Tutt is a leading German restorer of historic vehicles whose work graces many public and private museums. She has a particular interest in the science and technology of car paint and other finishes and is the founding member of the Institute for Automobile Forensics.[Photo: A restored 1907 veteran car.

Throughout its 130-year-old history, the ukulele has often been underrated – for many, this tiny four stringed instrument is a musical joke, a plastic toy or a cheap airport souvenir, but in fact, some of the world’s greatest musicians have played and admired it, and it has enduring associations with the struggle for Hawaiian independence since its arrival on the islands from Madeira in the late 19th century. The ukulele is also surprisingly versatile and musicians are forever involved in the challenge of expanding its repertoire, from Bach to ukulele concertos to jazz.Joining Bridget Kendall to find out more about this deceptively humble instrument is the award-winning musician Brittni Paiva, who’s been described as Hawaii’s pre-eminent ukulele artist; Jim Beloff, the co-founder of Flea Market Music, publishers of some of the first ukulele song books which played a key part in the modern ukulele revival, his forthcoming memoir is UKEtopia: Adventures in the Ukulele World; and Samantha Muir, a classical ukulele musician and composer, who’s doing a PHD at the University of Surrey in the UK to create new works for the classical ukulele repertoire.

The American president Thomas Jefferson called Tadeusz Kosciuszko "as pure a son of liberty as I have ever known". Kosciuszko was born in what is today Belarus, trained as an engineer in Poland and France and went on to become one of the important military players in the American War of Independence. This was when he wasn’t pursuing his dream of a free Polish republic against the might of a conservative aristocracy and neighbouring Russian and Prussian armies. Or campaigning against slavery and feudalism. Testimonials like that of Jefferson’s lauding his humility, energy and high moral principles flowed from around the world. He was toasted as a celebrity in London by the likes of Keats and Coleridge. In the USA and Europe there are bridges, statues and monuments in his name. And yet today Kosciuszko is relatively unknown outside of Poland. Rajan Datar aims to change that with the aid of three Kosciuszko experts: Dr. Betsey Blakeslee, President of the Friends of the American Revolution at West Point, an organisation that works to preserve the fortifications Kosciuszko designed and built at West Point. She earned her PhD in American Studies at the University of Maryland; Kamil Ruszala, Assistant Professor of History at Jagiellonian University in Kraków whose research focuses on the modern history of Central Europe; and writer and Pulitzer-prize-winning journalist Alex Storozynski, Chairman of the Board of the Kosciuszko Foundation and author of Kosciuszko's biographies both in a book and film form.[Image: A portrait of Tadeusz Kosciuszko.

Anyone who has ever researched their family tree will have most likely come across the census, the process by which every citizen or subject of a country is counted and classified. Data collected by the census, often carried out every ten years, has been invaluable to genealogists, both amateur and professional. And the census has also developed into an essential tool for governments and organisations to plan how and where they focus their investment in public services such as health care and schools. Inventories of people are known to stretch back to antiquity in places such as Egypt and China, and asked for very basic information for the purposes of tax collection or military service. The modern-day census, however, focuses on questions that touch far more on an individual’s identity and has often been controversial. Now that modern technology makes population data easily accessible in a variety of forms, some are questioning whether there is a need for censuses at all.Bridget Kendall is joined by Dr Kathrin Levitan, Associate Professor at William & Mary in Williamsburg, Virginia and the author of A Cultural History of the British Census: Envisioning the Multitude in the Nineteenth Century; sociologist Dr Tukufu Zuberi, the Lasry Family Professor of Race Relations at the University of Pennsylvania and head of the African Census Analysis Project; and data scientist and economist Andrew Whitby, author of The Sum of the People: How the Census Has Shaped Nations from the Ancient World to the Modern Age.Produced by Fiona Clampin for the BBC World Service.(Photo: Campaigners protest outside the US Supreme Court in 2019 over the inclusion of a citizenship question in the 2020 US Census.

Like many traditional domestic crafts, knitting has experienced a huge surge in popularity in the 21st century, making it fashionable and even radical. But the history of hand knitting is still relatively obscure. The oldest knitted artefacts are Coptic socks found in Egypt dating from the fourth century AD, but although they look like modern-day knitting, they’re actually made using a technique called nalebinding or needle-binding. So what then are the real origins of knitting? How did it develop into so many different regional patterns, from the famous Fair Isle of Scotland to distinctive Nordic and South American variations?Joining Bridget Kendall to discuss the global history of knitting are Professor Sandy Black of the University of the Arts London, Norwegian textile designer, Annemor Sundbo, and an expert on South American knitting, Cynthia LeCount Samaké.Produced by Jo Impey for the BBC World Service.Image: Knitting on Taquile Island, Peru Image credit: Hadynyah / Getty Images

Considered to be one of literature’s supreme achievements, One Hundred Years of Solitude by the Colombian novelist Gabriel García Márquez is reported to be the most popular work of Spanish-language fiction since Don Quixote in the 17th century. Written in 1967, it tells the story of seven generations of the Buendía family, whose patriarch is the founder of a fictional Colombian village called Macondo. But why is it said this novel – which fuses the fantastical and the real – tells the story of Latin America and has given an entire continent its voice? Joining Bridget Kendall are Ilan Stavans, Professor in Latin American and Latino Culture at Amherst College in Massachusetts, in the United States, and the biographer of Gabriel García Márquez; María del Pilar Blanco, Associate Professor in Spanish American literature at Oxford University, and Parvati Nair, Professor of Hispanic, Cultural and Migration studies at Queen Mary, University of London.Produced: Anne Khazam (Photo: Partial view of a mural painting by Oscar Gonzalez and Andrew Pisacane representing passages from One Hundred Years of Solitude at the National Library in Bogota.

So prodigious was the polymath Rabindranath Tagore, there’s a saying in Bengal that one lifetime is not enough to consume all of his work. Poet, playwright, thinker, activist, educator, social reformer, composer, artist… the list of his talents is long. Today his name is known all over India and Bangladesh; children recite his poetry at school and his legacy lives on in many different ways. When he became the first non-European to win the Nobel Prize for Literature in 1913, Tagore was feted for a time by American and European literary figures who saw in him someone who embodied Western preconceptions of a mystic Oriental sage. As a result of his newfound fame outside India, Tagore travelled widely and exchanged ideas with many celebrated world leaders and thinkers from Einstein to Gandhi. Today Tagore’s thoughts on education and his stance vis-à-vis the natural world and our relationship to the environment are seen as remarkably forward-looking.Rajan Datar is joined by Kathleen O’Connell, retired lecturer in South Asian Studies from the University of Toronto and the author of Rabindranath Tagore: the Poet as Educator; the writer Aseem Shrivastava who lectures on Tagore and his ecological thought at Ashoka University in Delhi; and Chandrika Kaul, Reader in Modern History at the University of St Andrews, who’s published widely on imperial and modern India.Produced by Fiona Clampin for the BBC World Service.[Photo: Rabindranath Tagore.

While the name of Pauline Viardot may be unfamiliar to many, in her lifetime she was one of the most celebrated performers in Europe. Her interpretation of Orpheus in a revival of Gluck’s opera made the writer Charles Dickens weep, and the novelist George Sand said that whenever she heard Pauline Viardot sing, nothing else mattered. In addition to her vocal talents, Pauline Viardot dazzled in high society. She knew almost everybody who came to define 19th Century European culture, thanks to the regular salon she held with her husband in their Parisian townhouse. Acclaimed poets, musicians, composers, artists and even royalty would come to take tea, listen to music, network, perform and share ideas.Alas there are no recordings of her magnificent voice, even though her later years coincided with the beginning of the recording industry. But today Pauline Viardot’s legacy is being rediscovered as a composer, with works that were performed at her salons reaching new audiences.Bridget Kendall is joined by Hilary Poriss, associate professor of music history at Northeastern University in Boston who is writing a monograph on Pauline Viardot to be published by the University of Chicago Press; Patrick Barbier, emeritus professor at the West Catholic University in Angers, and author of a biography of Pauline Viardot and her sister; and Richard Langham Smith, who has published widely on 19th and early 20th Century French music and is currently research professor at the Royal College of Music in London.

The One Thousand and One Nights are a collection of fantastical stories of flying carpets, magic and genies whose ancient origins go back to the 7th century or earlier. The tales are told by Scheherazade who uses the power of storytelling night after night to stop her Sultan husband from beheading her. These highly influential stories were brought to the West in the 18th century, when more tales like Aladdin and Ali Baba were said to have been added by the French translator, and it has continued to evolve over the centuries. Rajan Datar and guests explore why these stories became so popular around the world and what they mean to us today.Joining Rajan is Wen Chin Ouyang, Professor of Arabic at SOAS in London; Dr Sandra Naddaff, senior lecturer in Comparative Literature at Harvard University; and the Iranian TV producer Shabnam Rezaei.[Photo: Sand Sculpture depicting 1001 Nights of Sheherazade.

Until the eighteenth century there were no professional dentists. The only way to deal with a serious case of toothache was to call on the services of blacksmiths, travelling showmen or so-called barber-surgeons, all of whom had a sideline in tooth extraction. But in 1728, French physician Pierre Fauchard published the first complete scientific description of dentistry and he is credited as being “the father of modern dentistry”. His book, Le Chirurgien Dentiste or The Surgeon Dentist, was translated into several languages.Joining Rajan Datar to discuss the painful and sometimes gruesome history of humans and their teeth are Dr. Scott Swank of the National Museum of Dentistry in Baltimore, US; Rachel Bairsto, Head of Museum Services at the British Dental Association and Professor Dominik Gross of RWTH Aachen University in Germany.[Image: Detail from Tearer of Teeth or The Tooth Puller by David Ryjckaert III (1612-1661).

Educate, Agitate, Organise. This was the motto of the Indian scholar BR Ambedkar who led an extraordinary life of activism and achievement. It put him in conflict with many other political forces in his native country, such as the Indian National Congress and Mahatma Gandhi. In India itself, Ambedkar's legacy is widely respected but in other countries he is not so well known. And yet, Ambedkar was not only a leading intellectual of his day, brilliant orator, lawyer, successful politician and an unmatched champion of those suffering the harshest discrimination: he was also someone who rose from a Dalit background to being put in charge of writing the first constitution of independent India. The Dalits are the lowest of the low in the Indian social hierarchy, often considered as being below the lowest caste.To tell Ambedkar's story Rajan Datar is joined by three distinguished Ambedkar scholars: Sunil Khilnani, professor of politics and history at Ashoka University and author of Incarnations: India in Fifty Lives; Valerian Rodrigues, emeritus professor of political studies at Jawaharlal Nehru University and first Ambedkar chair at Ambedkar University, both in New Delhi, and author of The Essential Writings of B.R. Ambedkar; and Ananya Vajpeyi, associate professor at the Centre for the Study of Developing Societies in New Delhi and author of Righteous Republic: The Political Foundations of Modern India.[Photo: A statue of BR Ambedkar at Rashtriya Dalit Prerna Sthal in Noida, India.

Common to many cultures across the world, swimming appears on the surface to be a benign leisure activity. But in fact it has much to tell us about such things as the development of societies, our bodies and minds, and our relationship to our ancestors and the natural world.For the Ancient Greeks and Romans, swimming was essential for instilling discipline, as a necessary skill for warriors, and to promote wellbeing. In West Africa where water had spiritual significance, communities there placed great importance on learning to swim from an early age. Their aquatic skills surprised the early colonialists, who then targeted divers to help them plunder shipwrecks when they were trafficked to the New World. Today however African American children are almost six times more likely to drown than their white counterparts as a consequence of historic racial segregation, according to research by the US Centers for Disease Control.Rajan Datar is joined Professor Kevin Dawson from the University of California Merced, author of Undercurrents of Power: Aquatic Cultures in the African Diaspora; Mikael Rosén, swimmer, coach and author of Open Water: The History and Technique of Swimming; journalist Howard Means, author of Splash!: Ten Thousand Years of Swimming and writer Bonnie Tsui whose book Why we Swim was published in 2020.Produced by Fiona Clampin for the BBC World Service.[Photo: Young boys swim together at an inter-racial camp circa 1948 in New York, New York.

Many students of psychology, business, nursing and other disciplines are taught about "Maslow's pyramid of human needs", a diagram that shows a progression from our basic needs, such as food and shelter, to higher, social needs and, eventually, to striving for often intangible life goals and fulfilment. The pyramid is an iconic image, yet Abraham Maslow, a leading humanistic psychologist of the 20th century, didn't actually create it. Moreover, his writings are much more sophisticated and perceptive than the diagram suggests. So where did this confusion come from and why didn't Maslow disown the pyramid? How should we understand Maslow's hierarchy of human needs? Why has it proved so useful in so many different disciplines? And in what way is it relevant to how we live today?These are some of the questions that Bridget Kendall explores with Jessica Grogan from University of Texas at Austin, author of Encountering America, a history of humanistic psychology; David Baker, emeritus professor of psychology and former director of the Cummings Center for the History of Psychology at the University of Akron; and Scott Barry Kaufman, former director of the Imagination Institute at the University of Pennsylvania and author of Transcend which updates Maslow for the 21st century.[Photo: Abraham Maslow, undated photograph.

When the Kalevala was published in 1835, Finland had a distinct cultural and linguistic identity but it had always been part of either the Swedish or the Russian empire. Neither did Finland have much of a literary tradition, but as the 19th-century progressed the Kalevala took on a symbolic role as the representation of a Finnish identity that fed into the movement for Finnish independence. Rooted in the folk culture of the Karelia region, a travelling doctor shaped the song texts into a story in a way which is still being debated today.Joining Bridget Kendall to discuss how the Kalevala underscored the search for Finnish national identity are Dr Niina Hämäläinen, executive director of the Kalevala Society in Helsinki; Professor Tom DuBois from the University of Wisconsin-Madison, the author of Finnish Folk Poetry and the Kalevala; and the award-winning British musician, playwright and storyteller, Nick Hennessey.

Sister Juana Ines de la Cruz is celebrated today as one of the finest poets in the history of Mexico. She was not just a creative and intellectual force but also a campaigner for women’s education and someone not afraid to challenge male hypocrisy. The colonial 17th-century society in which she lived was very patriarchal so, not surprisingly, her views brought her into conflict with the men in power. Rajan Datar looks at key episodes in Sister Juana’s life and examines the passion and ingenuity in her poetry and plays with the help of Alicia Gaspar de Alba, Professor at University of California Los Angeles and a writer whose novels include Sor Juana’s Second Dream; Dr. Amy Fuller, Senior Lecturer at Nottingham Trent University, specialist in early modern Spain and Mexico and author of Between Two Worlds, a monograph on Sister Juana's plays; and Rosa Perelmuter, Professor of Romance Studies at University of North Carolina at Chapel Hill. The reader is Pepa Duarte.[Image: A painting of Sister Juana by the Mexican artist Miguel Cabrera (1695-1768). Credit: DeAgostini/Getty Images]

We delve into the watery depths of sea creature folklore, with a round-the-world tour of different variations on the concept of mermaids – from the Sirens of Greek mythology to the Selkies or Seal Folk of Scottish legend, and water spirits known as Mami Water, which are venerated in parts of Africa and the Americas. Not forgetting the famous fairy tale, The Little Mermaid, which has captivated the imagination ever since its publication in 1837 and was popularised by Disney in the 1980s.Joining Bridget Kendall to discuss what these ancient stories can tell us are Cristina Bacchilega of the University of Hawaii, co-editor of The Penguin Book of Mermaids; British writer, Marcelle Mateki Akita, who has written a book for children called Fatama and Mami Wata's Secret; and Lynn Barbour, founder and Arts Director of the Orkney Folklore and Storytelling Centre in the Orkney Islands in Scotland.Produced by Jo Impey for the BBC World Service.[Image: Detail from Fisherman and Mermaids in the Blue Grotto on Capri by Hermann Corrodi (1844-1905).

In ancient Greece, thousands of people flocked each year to join the religious rites known as the Eleusinian Mysteries. Based on the cult of the goddess of fertility Demeter and her daughter Persephone, the Mysteries were for many a profoundly moving and life-changing experience. People from all over the Greek world and beyond travelled to Eleusis for at least 800 years and the ceremonies remained a highlight of the Athenian calendar throughout that time. But what really went on in the great hall of the sanctuary at Eleusis? Why did the organisers deem it necessary to issue a strict injunction against divulging what actually took place - and what happened to some of those who broke that rule? These are some of the questions Bridget Kendall discusses with Christy Constantakopoulou, professor in ancient history and classics at Birkbeck College, London; Esther Eidinow, professor of ancient history at Bristol University; Dr. Philippe Michel Matthey who lectures about ancient religions at Geneva University; and Dr. Julietta Steinhauer, a lecturer in Hellenistic history at University College, London.[Image: Detail from a vessel showing a scene of the Eleusis cult with Triptolemus in a winged chariot and Demeter, c.460 BC.

Late 18th-Century Saint Domingue in the Caribbean – now known as Haiti – was one of the richest countries in the world. Known as ‘the pearl of the Antilles’, its wealth was built almost entirely on slavery. Around half a million enslaved Africans were transported to the French colony to work on the sugar plantations. Toussaint L’Ouverture was destined to see out his days within this brutal system, but his skills as a negotiator and communicator saw him rise to the forefront of the resistance movement on the island. A wily and charismatic operator, he galvanised his fellow countrymen and women to lead history’s first and only successful slave uprising. Diverging from French colonial rule brought him to the attention of Napoleon Bonaparte, who sent a large fleet to re-establish slavery on Saint Domingue. The expedition ended with Toussaint’s capture and exile to France, where he died in a cold prison cell in 1803. But his generals meanwhile carried on the struggle to uphold Toussaint’s opposition to slavery, which became the basis for the new independent state of Haiti.Joining Rajan Datar to explore this complex figure are Marlene L Daut, Professor of African Diaspora Studies in the Carter G. Woodson Institute at the University of Virginia, and the author of Tropics of Haiti: Race and the Literary History of the Haitian Revolution in the Atlantic World, 1789-1865; Weibert Arthus, the Haitian ambassador to Canada, who’s also published widely on Haitian diplomacy and history; and Sudhir Hazareesingh, professor in politics at Balliol College, Oxford. His biography Black Spartacus: The epic life of Toussaint Louverture was published in 2020.

She fought to give women the right to divorce and campaigned on behalf of children born out of wedlock. But in late 18th century France, her radical thinking proved too much for her contemporaries in the French revolution. She insisted women should be allowed to speak out, and she was executed at the guillotine for doing just that. For nearly two centuries her story was largely forgotten, until she was championed by modern-day French feminists, who called for her to be given pride of place in the pantheon of France’s national heroes.Joining Bridget Kendall to discuss the life of the French political activist and playwright Olympe de Gouges are: French philosopher of feminist thought, Geneviève Fraisse; Professor Catriona Seth of the University of Oxford; and British-French playwright and translator, Clarissa Palmer.Produced by Jo Impey for the BBC World Service.Image: Portrait of Olympe de Gouges (1748-1793) by Anonymous Image credit: Christophel Fine Art/Universal Images Group via Getty Images
