The Voynich manuscript, described as "the world's most mysterious manuscript", is a work which dates to the early 15th century, possibly from northern Italy. It is named after the book dealer Wilfrid Voynich, who purchased it in 1912. Currently the Voynich manuscript is owned by the Beinecke Rare Book and Manuscript Library of Yale University, and is formally referred to as "Beinecke MS 408". The first facsimile edition was published in 2005.
From the former wiki http://voynichmanuscript.wikia.com/wiki/Voynich_manuscript
The Voynich manuscript is a handwritten book thought to have been written in the 15th or 16th century and comprising about 240 vellum pages, most with illustrations. The author, script, and language remain unknown: for these reasons it has been described as "the world's most mysterious manuscript".
Generally presumed to be some kind of ciphertext, the Voynich manuscript has been studied by many professional and amateur cryptographers, including American and British codebreakers from both World War I and World War II. Yet it has defied all deciphering attempts, becoming a historical cryptology cause célèbre. The mystery surrounding it has excited the popular imagination, making the manuscript a subject of both fanciful theories and novels: numerous possible authors have been suggested for it.
In 2009, University of Arizona researchers performed C14 dating on the manuscript's vellum, which they assert (with 95% confidence) was made between 1404 and 1438. In addition, the McCrone Research Institute in Chicago found that much of the ink was added not long afterwards, confirming that the manuscript is indeed an authentic medieval document. However, these results have yet to be published properly, leaving room for continued speculation.

The following information has been copied from two Voynich Manuscript wikis which have been discontinued as there was no other activity:
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.
