Interest in the past and its secrets has always existed. After the publication of The Da Vinci Code, this interest spread to the widest layers of society. The only trouble is that they do not receive information about the secrets of the past from authentic documents of those centuries and believe everything that the author offers. But the true story was by no means a detective story or an adventure novel. She was life. And in that time, far from us, there lived people who had their own ideas about good and evil. They had friends and enemies, ancestors and descendants. And, of course, our secrets. Let's not be content with the invented book world, let's look at the mysterious past through the eyes of those who lived during the time of Christ, the Crusades, the Inquisition, and the first revolutions. And, reading ancient texts, we will try to understand what the world was like in those days and what secrets existed in it.
