Der gefälschte Mond von Galileo Galilei

Directed by Pierre-Olivier François

The story sounds like a gripping thriller: almost 400 years after its publication, a previously unknown copy of Galileo Galilei's "Sidereus Nuncius", the "Starry Messenger", has appeared on the international book market. Unlike in the known copies, Galileo allegedly drew the moons himself. Who is behind the forgery?
