The Voynich Question

History of the Manuscript
A book collector, Wilfrid Voynich, (after whom the manuscript is named) bought the medieval manuscript from the Jesuit College in Italy in 1912. Despite the efforts of various cryptologists and scholars, the manuscript remained unread but has been called the "Voynich manuscript" since then. The book was donated to Yale University in 1969 by H. P. Kraus where it remains to date at the Beinecke Rare Book Library with catalog number MS 408. It is possible to view the Voynich Manuscript by visiting this web page:
When it was found in 1912 by Voynich, a letter from Johannes Marcus Marci to Athanasius Kircher (a Jesuit priest and scholar in Rome) dated 1666 was still attached to the manuscript. In that letter, ( Marci mentioned that the manuscript was bought by Emperor Rudolph II of Bohemia (1552-1612) for 600 ducats (a very large amount in those days for a manuscript).

Marci also tells that the un-named previous owner believed the author was Roger Bacon, the 13th century Franciscan monk, philosopher, mathematician, and alchemist. Bacon frequently referred in his works to the necessity of hiding his great secrets in cipher. That's the reason why the manuscript is sometimes also called a "Roger Bacon's cipher."
