Sidereus Nuncius was the first book of its kind to show the lunar surface as mountainous and also contained observations of the four satellites orbiting Jupiter. These findings were vital in disproving the heliocentric view of the Earth that many had up until that point.
What made this copy so special was that it featured not only Galileo’s signature, but also a stamp from the library of Rome’s Lincean Academy. When it was discovered, the authenticity was immediately put into question. Galileo scholars were quick to discover some irregularities with the book, such as the paper not having the feel of 17th century work to the stamp not looking authentic.
Eventually, a man was arrested on suspicion of stealing and selling books from Girolamini Library in Naples, and it was discovered that he was connected to the forged book.
All of this is explored in a new documentary Galileo’s Moon, which airs on PBS tonight at 8pm.
