What do you know about the Ark of the Covenant? Were you aware that it is the most significant cult object for Jews and Christians? But what is hidden within it, what exactly is it? Were the Ten Commandments stored inside? Was it a technical apparatus or even a device for communicating with the gods? Officially, it has never been found. Some sources claim it has vanished without a trace. Others believe it is kept in Ethiopia. It has even been speculated to be in Jordan, southern France, and the Himalayas. Still, others assert that it is in the possession of a secret society and has been changing its location regularly for centuries. In this book, Stefan Erdmann reveals for the first time details about a mysterious find by the Knights Templar in 1118, which they brought from Jerusalem to France and which became the foundation for their immense wealth.
