History of Colors | Story for Sleep
In this week's story, we explore the significance attached to various colors throughout history, how pigments and dyes were made and with what surprising ingredients and how the status of colors changed over time in society, consumer goods and art. I focus on three colors in particular, which are global favorites: blue, green and red.

Roman Mythology: the Aeneid | History for Sleep
This soft-spoken sleep talk tells the story of the Aeneid and explains its historical and political significance. Join me and we will follow Aeneas on his adventures from Troy, which he had to endure with his son Ascanius and his father Anchises, under the protection of his mother Venus, to the Latium in Italy where war had to be fought before Rome could be founded. Aeneas benefits from Venus' protection and Jupiter's benevolence, but hostile deities like Juno will do anything to stop him. On the way, we will visit Thrace, Delos, Crete, Epirus, Sicily, Carthage and its queen, Dido, and even the Underworld.

Sleep Mystery Stories: Voynich Manuscript, Phaistos Disk, Sailing Stones
In this soft-spoken bedtime story, I tell you about historical and scientific mysteries and their context:
- The Voynich Manuscript, a strange codex apparently from the early 15th Century, written in an unknown language.
- The Phaistos Disc, an artifact discovered in Crete in the ruins of a Minoan palace, with what looks like a script, but that has always resisted attempts at deciphering it.
- The Sailing Stones from the Racetrack Playa, California, a rare geological phenomenon that was finally explained over the past few decades.

History of Medicine | Story for Sleep
This bedtime story is about medicine and healing since the Neolithic. I will tell you about Ancient Mesopotamia and the first diagnosis and prescriptions, Ancient Egypt and the figure of Imhotep, India, and the principles of Ayurveda, or Chinese Medicine including Moxibustion and Acupuncture. We also take a look at medicine in Ancient Greece and Rome, including important figures like Hippocrates and Galen, and how this legacy passed on and was further developed in the Islamic World, Byzantium, and Medieval Europe. Then we reach the Renaissance and the steps that would lead to an increasingly scientific approach to medicine and the many discoveries of the 19th and 20th centuries, that came with important social change and professionalization (I tell you at the end about scientists like Pasteur or Koch, and Florence Nightingale, the founder of modern nursing).

Stonehenge and its Ancient Mysteries | Sleep History
In tonight's story, I discuss the long history of Stonehenge, from the first works on the site by people from the Windmill Hill culture around 3100 BC, to the multiple works and rearrangements that took place until 1600 BC. After this, Stonehenge continued to live a life of its own and was adopted by the druids, became a legendary monument, and revealed extraordinary secrets since the 20th century. After Stonehenge, I also tell you of Skara Brae, a very well preserved neolithic village in the Orkney Islands (Scotland), and we explore its 5000-year-old houses.

Three Mysteries: Donner Party, Oak Island, Bermuda Triangle | Sleepy Mysteries from History
This episode details three different historical mysteries. First, we will relive the voyage of the Donner Party, a group of migrants who traveled from Illinois to California in 1846, but did not manage to reach their destination before the winter and had to set camp in the Sierra Nevada, until they were rescued in 1847. Second, we will travel to Oak Island, a small island in Nova Scotia that has become famous as a place where a fabulous treasure or even historical artifacts would be hidden. Finally, I will tell you of the Bermuda Triangle, the concept from the 1950s and 60s that a large area of the Atlantic, East of Florida, saw too many disappearances of ships and aircraft.
