From the http://vms.wikia.com/wiki/Main_Page wiki
The Voynich Manuscript is a document supposedly written many years ago by an unknown author, in an unknown language that to this day has gone untranslated. Though we can only guess at the exact meanings of its contents, it has been divided into several sections, including Cosmological and Astrological, based on the differences from one section to the other, including the kind of illustrations included, and the format in which the section is written.
Sections The Voynich Manuscript has been divided into six sections, based on the contents of the different sections. The sections are as follows: Herbal, Astronomical, Biological, Cosmological, Pharmaceutical, and Recipes.
This is a wiki dedicated to the discussion and eventual (we hope!) deciphering of the Voynich manuscript, a handwritten book thought to have been written in the 15th or 16th century. Its author, script, and language remain unknown: for these reasons it has been described as "the world's most mysterious manuscript". It has been studied by many professional and amateur cryptographers, yet it has always defied all deciphering attempts.
