Greek Myths: Pandora, Danaïdes, Sisyphus, Icarus | Sleep Story, Human Voice, No AI
In this soft-spoken bedtime story, I tell you about four Greek myths:
• Pandora and her jar (or box), which according to Hesiod contained countless plagues that she let escape, providing a backstory for the existence of suffering in human life. This myth works as a "theodicy" (a backstory or an argument that explains why evil is part of the human condition when God(s) would have the power to avoid it). It is also connected to the biblical character of Eve, and scratching the surface by looking at different versions of this myth reveals a more ambivalent figure:
• The tragedy of the Danaïdes, daughters of King Danaus condemned to a futile task forever for the murders of their husbands.
• Sisyphus, the king of Corinth, who was sentenced to another eternity of useless work for defying Zeus and cheating death. He was punished for his hubris: the overconfidence that made him lose touch with the reality of his condition.
• Icarus, the young man who flew too close to the sun and fell, is another example of hubris.
In this remastered edition, I've also added several new details and lesser-known stories. We'll discover how Pandora's family connects to the Greek myth of the great flood, an unexpected connection between Sisyphus and Odysseus, and how the philosopher Albert Camus interpreted Sisyphus's eternal punishment. Finally, we'll explore a darker side of Daedalus through the story of his gifted nephew, which gives the tragic fate of Icarus a different perspective.

Anatomy of a Myth: The Complete History of the Vampire (Bedtime Story)
Where did the idea of the vampire come from? In this Halloween special, we will trace the myth from ancient creatures like Lilith and Lamia to medieval stories of the restless dead, vampire panics in Eastern Europe, and figures such as Vlad the Impaler and Elizabeth Báthory. We will also look at how literature transformed vampires in novels like The Vampyre, Carmilla, and Dracula, before cinema gave us Bela Lugosi, Nosferatu, and the modern vampire we recognize today. Get ready to see how fear, folklore, disease, and imagination shaped the legend.

Greek Mythology and History: The Trojan War and the Iliad
In this soft-spoken story, I tell you about Greek mythology around the Trojan War. We explore its storylines and numerous characters, from gods like Zeus, Athena, Apollo, Aphrodite, and Hera to heroes and other mortals: Menelaus, Agamemnon, Odysseus, Achilles, Ajax, Patroclus, Hector, Priam, Paris, Aeneas, Helen of Troy, and many more. Discover how the feud between the gods over Eris’ golden apple spilled over into the world of men, and everything that ensued. I also tell you about the Trojan Horse, various other myths, and archaeology: When and how did Greek mythology take shape? Was Troy real? Where is the frontier between legend and history?
This is a remastered and expanded version of one of my earlier episodes, with improved audio and new material. I have added discoveries and historical evidence that help us look more closely at the possible reality behind the legend, including Hittite records referring to Wilusa and Ahhiyawa, more about the archaeology and different layers of Troy, and what we know about the city during the Late Bronze Age. I have also expanded parts of the traditional story, including the warnings of Cassandra and Laocoön and the ancient sources that tell us about the Trojan Horse.

The World of Bees | Documentary Sleep Story
Tonight, I take you to the wonderful world of bees. I tell you about the most famous social species, the western honey bee, but there are thousands more and not all of them are social. We will also discover solitary species like carpenter bees, mason bees or leafcutter bees. Other species are parasitic brood, like the cuckoo bumblebee. Apart from these, eusocial species live in elaborate societies in which all individuals are specialized by function and only live for and thanks to the nest they belong to. The way they collect pollen and nectar, and their production of beeswax, honey and royal jelly all serve to ensure the survival and development of the hive.

What is the Multiverse? Science, Philosophy & Science Fiction Story for Sleep
This episode will give you an overview of the concept of multiverse: where does it come from? What are the various meanings and ideas behind that term? I detail different versions of this idea, coming from cosmology such as the "Eternal Inflation Multiverse" and the "Cosmic Landscape Hypothesis" derived from String Theory, quantum mechanics (the "Many-Worlds Interpretation"), and the "Computational Multiverse" hypothesis. I also tell you about thinkers such as Anaximander, Copernic, and Giordano Bruno, who all contributed in their own ways to the intellectual revolutions necessary for this concept to emerge.

History of Cosmetics, From Antiquity Down to Our Days
Tonight’s episode is a remastered version of one of the first stories ever released on the podcast. The original version covered cosmetics and perfumes; in this new version we expanded the history of cosmetics and left the history of perfumes for a future story.
The new material covers the influence of Hollywood and flapper culture, women who helped build the modern beauty industry, dangerous cosmetics and the rise of regulation, makeup during World War II, and the changing beauty culture of the 1950s and 1960s. We also explore the history of cosmetics, as we did in the original story, from ancient pigments and Egyptian kohl to Japanese beauty traditions, and more.

In this relaxing story, I tell you about the history of castles in Europe, from the first earthworks from the Bronze Age to Roman castra and finally medieval castles.

- Mysteries of Celtic culture, especially the druids: who were they and what was their role in Celtic societies?
- A journey to "lost cities", in particular Machu Picchu in Peru and Meroe in Nubia (Sudan)
- Forgotten gods of Antiquity, like Sol Invictus or Ishtar: their cults were once thriving across various cultures, but they fell into oblivion.This content is entirely scripted and recorded by real people, it includes no AI, and mid-roll ad breaks are turned off so that you can relax without interruption.

Mission to Mars: Space Travel and Terraformation
This episode is a remastered and improved version of one of the first stories ever released on the podcast. This new version includes updated information, as well as very recent results published in July 2026 from MAVEN, the spacecraft that spent more than 11 years studying Mars and the history of its atmosphere. I also talk about AstroRad, a new device tested in deep space that could help protect astronauts from some forms of space radiation.
As usual with our space cruises, I take you to Mars and back. To entertain you along the journey, I tell you about orbits, space travel, spacecraft, and some of the difficulties of manned missions, including microgravity, radiation, and the challenges of spending months in space. We also explore the history of Mars, its climate, geology, and environment, and finally the idea of terraforming the planet one day in the distant future—and what such an enormous project would actually involve.
