Mystery of the Lost Legion | Historical Mystery for Sleep
The Ninth Legion (Legio IX Hispana, also sometimes called the "Lost Legion") had a long history. It served under the command of Julius Caesar during the First Century BC, on the side of Octavian in the civil war against Mark Antony and Cleopatra, and was sent to Spain, Germania, Pannonia, and Britain. In Roman Britain, it fought against rebellions, including the rebellion of Queen Boudica in which it narrowly avoided destruction. But its trace was lost in Northern England in the early Second Century AD, which is highly unusual for such an important unit at a time when the Roman Empire was in good shape overall. Was it destroyed in Britain by Celtic tribes, sent to the Netherlands, or did it disappear in a later conflict in Judea or Cappadocia? In this story, we examine the hypotheses and historical context, which provides a good opportunity to explore what Roman legions were, the conquest of Roman Britain, and other aspects of Roman history.

History of Astrology | Story for Sleep
In this soft-spoken sleepy bedtime story, I tell you about the History of Astrology: how it appeared as a discipline that was not formally separated from Astronomy across different cultures (Babylon, China, India, Egypt, Greece, the Islamic World, the Maya...), and how it evolved. Western Astrology, with its zodiac signs, birth charts, horoscopes, and individualized predictions, is a tradition that began to form more than 2,000 years ago in the Eastern Mediterranean. Even though critiques of the practice are probably as ancient as Astrology itself (some Roman authors, Muslim scholars, and various religious traditions were vocal about their rejection of it), Astrology survived its separation from Astronomy and even thrived in the West since the 20th Century.

Lost Treasures: Knights Templar, Cathars, Fabergé Eggs
For tonight, I tell you the stories of different "lost treasures" and other legends attached to:1- The Knights Templar, a religious military order that emerged during the Crusades but became so wealthy and influential that it made powerful enemies;2- The Cathars, a Christian sect from the 12th to 14th Centuries in Southern France and Northern Italy, which was persecuted until it disappeared;3- The Fabergé Eggs, exquisite pieces of jewelry that were made for the Romanovs in Saint Petersburg in the decades before the Russian Revolution. Out of more than fifty, six eggs are now missing, but as the story of the "Third Imperial" egg indicates, they could maybe reappear one day.
