History of Cosmetics, From Antiquity Down to Our Days
Episode 140
Sunday, September 27, 2026 • Duration 01:18:31
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.

Mission to Mars: Space Travel and Terraformation
Episode 137
Sunday, September 6, 2026 • Duration 01:27:59
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.

History of Alexander the Great | Documentary for Sleep
Episode 136
Sunday, August 30, 2026 • Duration 01:20:40
Alexander the Great is a name that sounds almost more legendary than real. In tonight's episode, we will talk about his time, his life and his conquests.
Born from King Philip II of Macedon and Olympias of Epirus, educated by Aristotle, Alexander takes the lead of the League of Corinth, a coalition of Greek states. He leads his army into the conquest of the greatest empire of the time: the empire of the Achaemenids. He ends up conquering it entirely, defeating Darius III at the decisive battles of Issus and Gaugamela, and founding an empire that stretches from Greece to India, and Central Asia to Egypt. I will tell you what we know of the man himself too, and how his achievements changed the world.

History of Lost Cities: Machu Picchu, Meroë, Mohenjo-Daro (Sleep Story)
Episode 134
Sunday, August 16, 2026 • Duration 59:58
In this bedtime story, I tell you about three “lost cities” and the civilizations that built them:
• Machu Picchu, built as a retreat for Inca emperors 50 miles from their capital, Cusco, and largely forgotten by the outside world for more than 300 years.
• Meroë, the capital of the Kingdom of Kush, along with a brief history of Nubia and its relations with Egypt in antiquity. Before Meroë became the capital, Nubian kings from Kush founded Egypt’s Twenty-Fifth Dynasty, and during the first millennium BC, they covered Nubia with pyramids.
• Mohenjo-daro, a large and enigmatic city from the third millennium BC, built by the Indus Valley Civilization and later declining along with it.
