Yale University's Beinecke Rare Book Library is in possession of many fascinating historic texts, but perhaps its most perplexing item is a 600 year old, one-of-a-kind book known as the Voynich Manuscript. The textual content of this mysterious illustrated book is unknown because it is written in an unknown alphabet and unintelligible language, and despite the efforts of expert cryptographers over many decades, not a single word has been deciphered.

Curiosity of the book's content is fed by the bizarre, elaborate illustrations that appear throughout its pages. The manuscript appears to be made up of several sections, each containing distinctly different illustrations which shed little light on its contents. These illustrations include plants, some of them unidentifiable; astronomical/astrological charts; and groups of nude women bathing in tubs and pools shaped like human organs.

Closup of Illustration in Voynich ManuscriptThe book is named for Wilfrid M. Voynich, a Russian-American book dealer who acquired the manuscript in 1912. The book contains about 240 parchment pages, but appears to be missing several pages as evidenced by gaps in the page numbering. The actual origin and date of the book are vigorously debated, though most agree that it was written in central Europe in the late 1400s or during the 1500s. Several plant drawings inside the book have been identified as specimens from North America, so it is presumed that the book must not predate Columbus's voyage to the New World in 1492.

Writing Sample from Voynich ManuscriptDespite the fact that statistical analysis of its text reveals character patterns similar to natural languages, more than a few people are convinced that the manuscript originated as an elaborate hoax nothing more than arbitrary symbols arranged in a meaningless order. But because that contention is inherently unprovable, and because the manuscript's patterns seem to reflect real information, many experts and amateurs continue in efforts to decipher this holy grail of historical cryptology. Several individuals have separately claimed successful decoding of the text, but each such decoding relies on broad, unfounded guesses, rendering the results useless.

 
The Voynich manuscript is a mysterious, undeciphered illustrated book. It is thought to have been written in the 15th or 16th century.[1] The author, script, and language of the manuscript remain unknown.

Over its recorded existence, the Voynich manuscript has been the object of intense study by many professional and amateur cryptographers, including some top American and British codebreakers of World War II fame (all of whom failed to decrypt any portion of the text). This string of failures has turned the Voynich manuscript into a famous subject of historical cryptology, but it has also given weight to the theory that the book is simply an elaborate hoaxa meaningless sequence of arbitrary symbols.

The book is named after the Polish-American book dealer Wilfrid M. Voynich, who acquired it in 1912. Currently the Voynich manuscript is stored in the Beinecke Rare Book and Manuscript Library of Yale University as item "MS 408". The first facsimile edition was published in 2005.[2]

By current estimates, the book originally had 272 pages in 17 quires of 16 pages each.[3] About 240 vellum pages remain today, and gaps in the page numbering (which seems to be later than the text) indicate that several pages were already missing when Voynich acquired it. A quill pen was used for the text and figure outlines, and colored paint was applied (somewhat crudely) to the figures, possibly at a later date. There is strong evidence that at one point in time, the pages of the book were arranged in a different order.[4]

The "biological" section of the manuscript has dense text and illustrations showing nude women bathing.

The text was clearly written from left to right, with a slightly ragged right margin. Longer sections are broken into paragraphs, sometimes with "bullets" in the left margin. There is no obvious punctuation. The ductus flows smoothly, suggesting that the scribe understood what he was writing when it was written; the manuscript does not give the impression that each character had to be calculated before being inked onto the page.

The text consists of over 170,000 discrete glyphs, usually separated from each other by narrow gaps. Most of the glyphs are written with one or two simple pen strokes. While there is some dispute as to whether certain glyphs are distinct or not, an alphabet with 2030 glyphs would account for virtually all of the text; the exceptions are a few dozen rarer characters that occur only once or twice each.

Wider gaps divide the text into about 35,000 "words" of varying length. These seem to follow phonetic or orthographic laws of some sort; e.g., certain characters must appear in each word (like the vowels in English), some characters never follow others, and some may be doubled but others may not.

Statistical analysis of the text reveals patterns similar to those of natural languages. For instance, the word entropy (about 10 bits per word) is similar to that of English or Latin texts.[5] Some words occur only in certain sections, or in only a few pages; others occur throughout the manuscript. There are very few repetitions among the thousand or so "labels" attached to the illustrations. In the herbal section, the first word on each page occurs only on that page and may be the name of the plant.

On the other hand, the Voynich manuscript's "language" is quite unlike European languages in several aspects. Firstly, there are practically no words comprising more than ten glyphs, yet there are also few one- or two-letter words. The distribution of letters within the word is also rather peculiar: some characters only occur at the beginning of a word, some only at the end, and some always in the middle sectionan arrangement found in Semitic alphabets but not in the Latin or Cyrillic alphabets (with the exception of the Greek letters Beta and Sigma).

The text seems to be more repetitive than typical European languages; there are instances where the same common word appears up to three times in a row. Words that differ only by one letter also repeat with unusual frequency.

There are only a few words in the manuscript written in a seemingly Latin script. On the last page, there are four lines of writing that are written in (rather distorted) Latin letters, except for two words in the main script. The lettering resembles European alphabets of the 15th century, but the words do not seem to make sense in any language.[6] Also, a series of diagrams in the "astronomical" section has the names of ten of the months (from March to December) written in Latin script, with spelling suggestive of the medieval languages of France or the Iberian Peninsula.[7] However, it is not known whether these bits of Latin script were part of the original text or were added later.

[edit] Illustrations

The "herbal" section of the manuscript contains illustrations of plants.

The illustrations of the manuscript shed little light on its contents but imply that the book consists of six "sections", with different styles and subject matter. Except for the last section, which contains only text, almost every page contains at least one illustration. Following are the sections and their conventional names:

    * Herbal. Each page displays one plant (sometimes two) and a few paragraphs of texta format typical of European herbals of the time. Some parts of these drawings are larger and cleaner copies of sketches seen in the "pharmaceutical" section (below). None of the plants depicted is unambiguously identifiable.[citation needed]

    * Astronomical. Contains circular diagrams, some of them with suns, moons, and stars, suggestive of astronomy or astrology. One series of 12 diagrams depicts conventional symbols for the zodiacal constellations (two fish for Pisces, a bull for Taurus, a hunter with crossbow for Sagittarius, etc.). Each of these has 30 women figures arranged in two or more concentring bands. Most of the females are at least partly naked, and each holds what appears to be a labeled star or is shown with the star attached by what could be a tether or cord of some kind to either arm. The last two pages of this section (Aquarius and Capricornus, roughly January and February) were lost, while Aries and Taurus are split into four paired diagrams with 15 women and 15 stars each. Some of these diagrams are on fold-out pages.

A detail from the "biological" section of the manuscript

    * Biological. A dense continuous text interspersed with figures, mostly showing small naked women bathing in pools or tubs connected by an elaborate network of pipes, some of them clearly shaped like body organs. Some of the women wear crowns.

    * Cosmological. More circular diagrams, but of obscure nature. This section also has foldouts; one of them spans six pages and contains a map or diagram, with nine "islands" connected by "causeways", castles, and what may be a volcano.

    * Pharmaceutical. Many labeled drawings of isolated plant parts (roots, leaves, etc.); objects resembling apothecary jars drawn along the margins; and a few text paragraphs.

    * Recipes. Many short paragraphs, each marked with a flower- or star-like "bullet".

[edit] History

Wilfrid Voynich

The history of the manuscript is still full of gaps, especially in its earliest part.[8] Since the manuscript's alphabet does not resemble any known script, and the text is still undeciphered, the only useful evidence as to the book's age and origin are the illustrationsespecially the dress and hairstyles of the human figures and a couple of castles that are seen in the diagrams. They are all characteristically European, and based on that evidence, most experts assign the book to dates between 1450 and 1520. This estimate is supported by other secondary clues.

The earliest confirmed owner of the Voynich manuscript was Georg Baresch, an obscure alchemist who lived in Prague in the early 17th century. Baresch apparently was just as puzzled as we are today about this "Sphynx" that had been "taking up space uselessly in his library" for many years.[9] On learning that Athanasius Kircher, a Jesuit scholar from the Collegio Romano, had published a Coptic (Ethiopian) dictionary and "deciphered" the Egyptian hieroglyphs, Baresch sent a sample copy of the script to Kircher in Rome (twice), asking for clues. His 1639 letter to Kircher, which was recently located by Rene Zandbergen, is the earliest mention of the manuscript that has been found so far.

It is not known whether Kircher answered the request, but apparently, he was interested enough to try to acquire the book, which Baresch apparently refused to yield. Upon Baresch's death, the manuscript passed to his friend Jan Marek Marci (Johannes Marcus Marci), then rector of Charles University in Prague, who promptly sent the book to Kircher, his longtime friend and correspondent. Marci's cover letter (1666) is still attached to the manuscript.

There are no records of the book for the next 200 years, but in all likelihood, it was kept, with the rest of Kircher's correspondence, in the library of the Collegio Romano (now the Pontifical Gregorian University). It probably remained there until the troops of Victor Emmanuel II of Italy captured the city in 1870 and annexed the Papal States. The new Italian government decided to confiscate many properties of the Church, including the library of the Collegio. According to investigations by Xavier Ceccaldi and others, just before this happened, many books of the University's library were hastily transferred to the personal libraries of its faculty, which were exempt from confiscation. Kircher's correspondence was among those booksand so apparently was the Voynich manuscript, as it still bears the ex libris of Petrus Beckx, head of the Jesuit order and the University's Rector at the time.

Beckx's "private" library was moved to the Villa Mondragone, Frascati, a large country palace near Rome that had been bought by the Society of Jesus in 1866 and housed the headquarters of the Jesuits' Ghislieri College.

Around 1912, the Collegio Romano was apparently short of money and decided to sell (very discreetly) some of its holdings. Wilfrid Voynich acquired 30 manuscripts, among them the manuscript that now bears his name. In 1930, after his death, the manuscript was inherited by his widow, Ethel Lilian Voynich (known as the author of the novel The Gadfly and daughter of famous mathematician George Boole). She died in 1960 and left the manuscript to her close friend, Miss Anne Nill. In 1961, Anne Nill sold the book to another antique book dealer, Hans P. Kraus. Unable to find a buyer, Kraus donated the manuscript to Yale University in 1969.
