Seashells

Seashells

Author: BBC July 30, 2026 Duration: 56:42
Misha Glenny and guests discuss a familiar feature of our beaches: seashells, from their astonishing shapes and patterns that teach us about Earth’s oceans, to the ways that humans have treasured shells throughout history. Seashells appear in the mythologies of countless cultures across the world - think of Botticelli’s Venus emerging from a giant scallop shell, Vishnu's sacred horn panchajanya, or the Aztec god Quetzalcōātl’s talisman cut from a conch shell. The urge to collect shells seems to be as old as our species. We’ve used them as decoration, currency, and musical instruments. But shells aren’t just beautiful objects washed up on our beaches. Many belong to one of the most diverse groups of the animal kingdom, Mollusca, and the remarkable morphology of forms and structures they grow in offer insight into the past, present, and future of the marine world.

For decades, Melvyn Bragg has convened some of the world's sharpest minds around a single, unassuming table, and the resulting conversations form the heart of In Our Time With Melvyn Bragg. This BBC podcast is less a formal lecture and more an eavesdropped dialogue, where complex ideas from religion, philosophy, science, and history are unpacked with genuine curiosity and clarity. Each episode focuses on a single concept, event, or figure-from the intricacies of Islamic philosophy to the paradoxes of quantum mechanics, from the rise of the novel to the fall of ancient empires. Listeners are brought directly into a thoughtful, often lively discussion where experts debate, clarify, and connect the dots, guided by Bragg's probing yet generous questioning. You'll hear the context and contradictions behind the ideas that have shaped our spiritual and intellectual landscape, presented not as dry facts but as living, debated history. The enduring appeal of this podcast lies in its depth and accessibility, transforming daunting subjects into compelling narratives. It’s a weekly invitation to step back from the noise and spend forty-five minutes engaged in the kind of substantive, ad-free conversation that reminds us of the profound connections between all fields of human thought.
