[Resources] The Voynich Manuscript

The Voynich Manuscript is a 240 page 15th century manuscript filled with illustrations and written in an unknown script and an equally unknown language. Believed to be a cypher-script, the book is "the world's most mysterious manuscript."
Since it's discovery in 1912, it has successfully resisted all attempts to translate. Cryptographers from both world wars and beyond have all failed to learn it's secrets. The text has nearly 200,000 distinct glyphs and illustrations that cover everything from herbs and botany to cartography and astronomy.

What secrets does this book have? And what language was it written in? The secret history possibilities alone are extensive.
