Gordon Rugg cracked the 400-year-old mystery of the Voynich manuscript. What's this? According to this site, "The Voynich Manuscript has been dubbed "The Most Mysterious Manuscript in the World". It is named after its discoverer,the American antique book dealer and collector, Wilfrid M. Voynich, who discovered it in 1912, amongst a collection of ancientmanuscripts kept in villa Mondragone in Frascati, near Rome, which had been by then turned into a Jesuit College (closed in 1953).
No one knows the origins of the manuscript. Experts believe it is European based on the drawings. They believe it was written in between the 15th and 17th centuries. The manuscript is small, seven by ten inches, but thick, nearly 235 pages."
