Voynich manuscriptFrom Wikipedia, the f ree encyclopedia
The Voynich manuscript is an
illustrated codex hand-written in an
unknown writing system. The vellum on
which it is written has been carbon-dated
to the early 15th century (1404–1438),
and it may have been composed in
Northern Italy during the Italian
Renaissance.[1][2] The manuscript is
named after Wilfrid Voynich, a Polish
book dealer who purchased it in 1912.[3]
Some of the pages are missing, with
around 240 still remaining. The text is
written fr om left to right, and most of the pages have illustrations or diagrams.
The Voynich manuscr ipt has been
studied by many professional and
amateur cryptographers, including
American and British codebreakers from
both World War I and World War II.[4]
No one has yet succeeded in deciphering
the text, and it has become a famous case
in the history of cryptography. Themystery of the meaning and origin of the manuscript has excited the popular imagination, making the
manuscript the subject of novels and speculation. None of the many hypotheses proposed over the last
hundred years has yet been independently verified.[5]
The Voynich manuscript was donated by Hans P. Kraus[6] to Yale University's Beinecke R are Book and
Manuscript Library in 1969, where it is catalogued under call number MS 408.[7][8]

Codicology
The manuscript measures 23.5 by 16.2 by 5 centimetres (9.3 by 6.4 by 2.0 in), with hundreds of vellum pages collected into eighteen quires. The total number of pages is around 240, but the exact number
depends on how the manuscript's unusual foldouts are counted.[8] The quires have been numbered from 1 t
20 in various locations, with numerals consistent with the 1400s, and the top righthand corner of each recto
(righthand) page has been numbered from 1 to 116, with numerals of a later date. From the various
numbering gaps in the quires and pages, it seems likely that in the past the manuscript had at least 272
pages in 20 quires, some of which were already missing when Wilfrid Voynich acquired the manuscript in
1912. There is strong evidence that many of the book's bifolios were reordered at various points in its
history, and that the original page order may well have been quite different from what it is today.[9][10]
The binding and covers are not original to the book, but date to during its possession by the Collegio
Romano.[8]
Every page in the manuscript contains text, mostly in an unknown script, but some have extraneous writing
in Latin script. Many pages contain substantial drawings or charts which are colored with paint. Based on
modern analysis, it has been determined that a quill pen and iron gall ink were used for the text and figure
outlines; the colored paint was applied (somewhat crudely) to the figures, possibly at a later date.[10]
Text
The bulk of the text in the manuscript of 240 pages is written in an
unknown script, running left to right. Most of the characters are
composed of one or two simple pen strokes. While there is some
dispute as to whether certain characters are distinct or not, a script of
20–25 characters would account for virtually all of the text; the
exceptions are a few dozen rarer characters that occur only once or
twice each. There is no obvious punctuation.[11]
Much of the text is written in a single column in the body of a page,
with a slightly ragged right margin and paragraph divisions, andsometimes with stars in the left margin.[8] Other text occurs in charts
or as labels associated with illustrations. There are no indications of
any errors or corrections made at any place in the document. The
ductus flows smoothly, giving the impression that the symbols were
not enciphered, as there is no delay between characters as would
normally be expected in written encoded text.

The text consists of over 170,000 characters,[12] with spaces dividing the text into about 35,000 groups of
varying length, usually referred to as "words". The structure of these words seems to follow phonological o
orthographic laws of some sort, e.g., certain characters must appear in each word (like English vowels),
some characters never follow others, some may be doubled or tripled but others may not, etc. The
distribution of letters within words is also rather peculiar: some characters occur only at the beginning of a
word, some only at the end, and some always in the middle section. Many researchers have commented
upon the highly regular structure of the words.[13]
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. There are
practically no words with fewer than two letters or more than ten.[12] There are instances where the same
common word appears up to three times in a row.[12] Words that differ by only one letter also repeat with
unusual frequency, causing single-substitution alphabet decipherings to yield babble-like text. In 1962,
Elizebeth Friedman described such attempts as "doomed to utter frustration".[14]
Various transcription alphabets have been created to equate the Voynich characters with Latin characters in
order to help with cryptanalysis, such as the European Voynich Alphabet. The first major one was created
by cryptographer William F. Friedman in the 1940s, where each line of the manuscript was transcribed to
an IBM punch card to make it machine readable.[15]
Extraneous writing
Only a few words in the manuscript are considered not to be written in the unknown script:[16]
f1r : A sequence of Latin letters in the right margin parallel with characters from the unknown script.There is also the now unreadable signature of "Jacobj à Tepenece" in the bottom margin.
f17r : A line of writing in the Latin script in the top margin.
f70v–f73v: The astrological series of diagrams in the astronomical section has the names of ten of thmonths (from March to December) written in Latin script, with spelling suggestive of the medieval
languages of France, northwest Italy or the Iberian Peninsula.[17]
f66r : A small number of words in the bottom left corner near a drawing of a naked man. They have been read as "der musz del", a High German word for a widow's share. f116v: Four lines of writing written in rather distorted Latin script, except for two words in theunknown script. The words in Latin script appear to be distorted with characteristics of the unknownlanguage. The lettering resembles European alphabets of the late 14th and 15th centuries, but the
words do not seem to make sense in any language.[18]
It is not known whether these bits of Latin script were part of the original text or were added later.
Illustrations
Because the text cannot be read the illustrations are conventionally used to divide most of the manuscript
into six different sections. Each section is typified by illustrations with different styles and supposed subje
matter,[12] except for the last section, in which the only drawings are small stars in the margin. Following
are the sections and their conventional names:

parts were completed with improbable-looking details. In fact, many of the plant drawings in the herbal
section seem to be composite: the roots of one species have been fastened to the leaves of another, with
flowers from a third.[19]
Hugh O'Neill believed that one illustration depicted a New World sunflower, which would help date the
manuscript and open up intriguing possibilities for its origin; unfortunately the identification is only
speculative.[12]
The basins and tubes in the "biological" section are sometimes interpreted as implying a connection to
alchemy, yet bear little obvious resemblance to the alchemical equipment of the period.
Astrological considerations frequently played a prominent role in herb gathering, bloodletting and other
medical procedures common during the likeliest dates of the manuscript. However, apart from the obvious
Zodiac symbols, and one diagram possibly showing the classical planets, interpretation remains
speculative.[12]
History
Much of the early history of the book is unknown,[20] though the text and illustrations are all
characteristically European. In 2009, University of Arizona researchers performed radiocarbon dating on
the manuscript's vellum. The result of that test put the date the manuscript was made between 1404 and
1438.[2][21][22] In addition, the McCrone Research Institute in Chicago found that the paints in the
manuscript were of materials to be expected from that period of European history. It has also been
suggested that the McCrone Research Institute found that much of the ink was added not long after the
creation of the parchment, but the official report contains no statement to this effect.[10]
The earliest historical information about the manuscript comes from a letter found
inside the cover—written in 1666 to accompany the manuscript when it was sent by
Johannes Marcus to Athanasius Kircher—which claims that the book once belonged t
Emperor Rudolf II (1552–1612), who paid 600 gold ducats (~2.07 kg gold) for it. The
book was then given or lent to Jacobus Horcicky de Tepenecz (died 1622), the head o
Rudolf's botanical gardens in Prague.
The next confirmed owner is Georg Baresch, an obscure alchemist also in Prague.
Baresch was apparently just as puzzled as modern scientists about this "Sphynx" that
had been "taking up space uselessly in his library" for many years.[23] On learning tha
Athanasius Kircher, a Jesuit scholar from the Collegio Romano, had published a
Coptic (Egyptian) dictionary and "deciphered" the Egyptian hieroglyphs, Baresch sen
a sample copy of the script to Kircher in Rome (twice), asking for clues. His 1639
letter to Kircher is the earliest confirmed mention of the manuscript that has been
found so far.[24]
It is not known whether Kircher answered the request, but apparently, he was interested enough to try to
acquire the book, which Baresch refused to yield. Upon Baresch's death, the manuscript passed to his frien

Wilfrid Voynich (1865–
1930) acquired the
manuscript in 1912
a few years later sent the book to Kircher, his longtime friend and correspondent.[24] Marci's 1666 cover
letter (written in Latin) was still with the manuscript when Voynich purchased it:[11]
Reverend and Distinguished Sir, Father in Christ:
This book, bequeathed to me by an intimate friend, I destined for you, my very dear
Athanasius, as soon as it came into my possession, for I was convinced that it could be read by
no one except yourself.
The former owner of this book asked your opinion by letter, copying and sending you a portion
of the book from which he believed you would be able to read the remainder, but he at that
time refused to send the book itself. To its deciphering he devoted unflagging toil, as is
apparent from attempts of his which I send you herewith, and he relinquished hope only with
his life. But his toil was in vain, for such Sphinxes as these obey no one but their master,
Kircher. Accept now this token, such as it is and long overdue though it be, of my affection for
you, and burst through its bars, if there are any, with your wonted success.
Dr. Raphael, a tutor in the Bohemian language to Ferdinand III, then King of Bohemia, told methe said book belonged to the Emperor Rudolph and that he presented to the bearer who
brought him the book 600 ducats. He believed the author was Roger Bacon, the Englishman.
On this point I suspend judgement; it is your place to define for us what view we should take
thereon, to whose favor and kindness I unreservedly commit myself and remain
At the command of your Reverence,Joannes Marcus Marci of Cronland
Prague, 19th August, 1666[11]
There are no records of the book for the next 200 years, but in all likelihood
it was stored with the rest of Kircher's correspondence in the library of the
Collegio Romano (now the Pontifical Gregorian University).[24] 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.[24] According to investigations by Xavier Ceccaldi and others,
ust 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.[24] Kircher's correspondence was among those books— and 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.[8][24]
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.[24]

Edward Kelley (1555–97)
might have created the
manuscript as a fraud.
Mathematician John Dee
(1527–1608) may have sold
the manuscript to Emperor
Rudolf around 1600.
Around 1912, the Collegio Romano was short of money and decided to sell some of its holdings discreetly
Wilfrid Voynich acquired 30 manuscripts, among them the manuscript that now bears his name.[24] He
spent the next seven years attempting to interest scholars in deciphering the script while he worked to
determine the origins of the manuscript.[11]
In 1930, after Wilfrid's death, the manuscript was inherited by his widow, Ethel Voynich (known as the
author of the novel The Gadfly and daughter of mathematician George Boole). She died in 1960 and left th
manuscript to her close friend, Miss Anne Nill. In 1961, 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, where it
was catalogued as "MS 408".[16] In discussions, it is sometimes also referred to as "Beinecke MS 408".[8]
Authorship hypotheses
Many people have been proposed as possible authors of the Voynich manuscript.
Marci's 1666 cover letter to Kircher says that, according to his friend, the
late Raphael Mnishovsky, the book had once been bought by Rudolf II,
Holy Roman Emperor and King of Bohemia (1552–1612), for 600 ducats(66.42 troy ounce actual gold weight, or 2.07 kg). (Mnishovsky had died 2
years earlier, in 1644, and the deal must have occurred before Rudolf's
abdication in 1611—at least 55 years before Marci's letter.) According to
the letter, Mnishovsky (but not necessarily Rudolf) speculated that the
author was the Franciscan friar and polymath Roger Bacon (1214–94).[25]
Even though Marci said that he was "suspending his judgment" about this
claim, it was taken quite seriously by Wilfrid Voynich, who did his best to
confirm it.[24]
The assumption that Roger Bacon was the
author led Voynich to conclude that the
person who sold the manuscript to Rudolf
could only have been John Dee (1527–
1608), a mathematician and astrologer at the
court of Queen Elizabeth I of England,
known to have owned a large collection of Bacon's manuscripts. Dee and
his scrier (mediumic assistant) Edward Kelley lived in Bohemia for several
ears, where they had hoped to sell their services to the emperor. However,
this seems quite unlikely, because Dee's meticulously kept diaries do not
mention that sale.[24] If the Voynich manuscript author is not Bacon, a
supposed connection to Dee is much weakened. Until the carbon dating of
the manuscript to the 15th century, it was thought possible that Dee or
Kelley may have written it and spread the rumor that it was originally a
work of Bacon's in the hopes of later selling it.

Some pages of the manuscript fold
out to show larger diagrams.
Some suspected Voynich of having fabricated the manuscript himself.[26] As an antique book dealer, he
probably had the necessary knowledge and means, and a "lost book" by Roger Bacon would have been
worth a fortune. Furthermore, Baresch's letter (and Marci's as well) only establish the existence of a
manuscript, not that the Voynich manuscript is the same one spoken of there. In other words, these letters
could possibly have been the motivation for Voynich to fabricate the manuscript (assuming he was aware o
them), rather than as proofs authenticating it. However, many consider the expert internal dating of the
manuscript and the recent discovery of Baresch's letter to Kircher as having eliminated this
possibility.[24][26]
Other theories
Voynich was able, sometime before 1921, to read a name faintly written at the foot of the manuscript's firs
page: "Jacobj à Tepenece". This is taken to be a reference to Jakub Hořčický of Tepenec (1575–1622), also
known by his Latin name Jacobus Sinapius. Rudolph II had ennobled him in 1607; appointed him his
Imperial Distiller; and had made him both curator of his botanical gardens as well as one of his personal
physicians. Voynich, and many other people after him, concluded from this that Jacobus owned the
Voynich manuscript prior to Baresch, and drew a link to Rudolf's court from that, in confirmation of
Mnishovsky's story.
Jacobus's name is still clearly visible under UV light: however, it does not match the copy of his signature
in a document located by Jan Hurych in 2003.[27] As a result, it has been suggested that the signature was
added later, possibly even fraudulently by Voynich himself. Yet because the writing on page f1r might we
have been an ownership mark added by a librarian at the time, the difference between the two signatures
does not necessarily disprove Horczicky's ownership.
It has been noted that Baresch's letter bears some resemblance to a hoax that orientalist Andreas Mueller
once played on Kircher. Mueller sent some unintelligible text to Kircher with a note explaining that it had
come from Egypt, and asking Kircher for a translation: which Kircher, reportedly, produced at once. It has been speculated that these were both cryptographic tricks played on Kircher to make him look foolish: but
the Voynich manuscript is on such a vastly different scale to a few signs in a letter that this seems
somewhat out of scale for such an endeavor.
Raphael Mnishovsky, the friend of Marci who was the reputed
source of Bacon's story, was himself a cryptographer (among many
other things) and apparently invented a cipher that he claimed was
uncrackable (ca. 1618). This has led to the speculation that
Mnishovsky might have produced the Voynich manuscript as a
practical demonstration of his cipher and made Baresch his
unwitting test subject. Indeed, the disclaimer in the Voynich
manuscript cover letter could mean that Marci suspected some kind
of deception was at play. However, there is no definite evidence for
this theory.
In his 2006 book, Nick Pelling proposed that the Voynich
manuscript was written by the 15th century North Italian architect
Antonio Averlino (also known as "Filarete"), a theory broadly
consistent with the radiocarbon dating.[9]

The Voynich manuscript is written in
an unknown script.
Richard SantaColoma has speculated that the Voynich Manuscript may be connected to Cornelis Drebbel,
initially suggesting it was Drebbel's cipher notebook on microscopy and alchemy, and then later
hypothesising it is a fictional "tie-in" to Francis Bacon's utopian novel New Atlantis in which some
Drebbel-related items (submarine, perpetual clock) are said to appear.[28]

There are many hypotheses about the Voynich manuscript's "language":
Ciphers
According to the "letter-based cipher" theory, the Voynich
manuscript contains a meaningful text in some European language
that was intentionally rendered obscure by mapping it to the
Voynich manuscript "alphabet" through a cipher of some sort—an
algorithm that operated on individual letters. This has been the
working hypothesis for most twentieth-century deciphering
attempts, including an informal team of NSA cryptographers led byWilliam F. Friedman in the early 1950s.
The main argument for this theory is that the use of a strange
alphabet by a European author is awkward to explain except as an
attempt to hide information. Indeed, even Roger Bacon knew about
ciphers, and the estimated date for the manuscript roughly coincides
with the birth of cryptography in Europe as a relatively systematic
discipline.
The counterargument is that almost all cipher systems consistent with that era fail to match what we see inthe Voynich manuscript. For example, simple monoalphabetic ciphers can be excluded because the
distribution of letter frequencies does not resemble that of any common language; while the small number
of different letter-shapes used implies that we can rule out nomenclator ciphers and homophonic ciphers,
because these typically employ larger cipher alphabets. Similarly, polyalphabetic ciphers, first invented by
Alberti in the 1460s and including the later Vigenère cipher, usually yield ciphertexts where all cipher
shapes occur with roughly equal probability, quite unlike the language-like letter distribution the Voynich
Manuscript appears to have.
However, the presence of many tightly grouped shapes in the Voynich manuscript (such as "or", "ar", "ol"
"al", "an", "ain", "aiin", "air", "aiir", "am", "ee", "eee", etc.) does suggest that its cipher system may makeuse of a ""verbose cipher"", where single letters in a plaintext get enciphered into groups of fake letters. Fo
example, the first two lines of page f15v (seen above) contain "or or or" and "or or oro r", which strongly
resemble how Roman numbers such as "CCC" or "XXXX" would look if verbosely enciphered. Yet, even
though verbose encipherment is arguably the best match, it still falls well short of being able to explain all
of the Voynich manuscript's odd textual properties.
It is also entirely possible that the encryption system started from a fundamentally simple cipher and then
augmented it by adding nulls (meaningless symbols), homophones (duplicate symbols), transposition ciphe
(letter rearrangement), false word breaks, and so on.

Codes
According to the "codebook cipher" theory, the Voynich manuscript "words" would actually be codes to b
looked up in a "dictionary" or codebook. The main evidence for this theory is that the internal structure and
length distribution of many words are similar to those of Roman numerals—which, at the time, would be a
natural choice for the codes. However, book-based ciphers are viable only for short messages, because the
are very cumbersome to write and to read.
Steganography
This theory holds that the text of the Voynich manuscript is mostly meaningless, but contains meaningful
information hidden in inconspicuous details—e.g. the second letter of every word, or the number of letters
in each line. This technique, called steganography, is very old, and was described by Johannes Trithemius
in 1499. Though it has been speculated that the plain text was to be extracted by a Cardan grille of some
sort, this seems somewhat unlikely because the words and letters are not arranged on anything like a regula
grid. Still, steganographic claims are hard to prove or disprove, since stegotexts can be arbitrarily hard to
find. An argument against steganography is that having a cipher-like cover text highlights the very
existence of the secret message, which would be self-defeating: yet because the cover text no less resemblean unknown natural language, this argument is not hugely persuasive.
It has been suggested that the meaningful text could be encoded in the length or shape of certain pen
strokes.[29] There are indeed examples of steganography from about that time that use letter shape (italic v
upright) to hide information. However, when examined at high magnification, the Voynich manuscript pen
strokes seem quite natural, and substantially affected by the uneven surface of the vellum.
Natural language
Statistical analysis of the text reveals patterns similar to those of natural languages. For instance, the wordentropy (about 10 bits per word) is similar to that of English or Latin texts.[30] In 2013, Diego Amancio et
al argued that the Voynich manuscript "is mostly compatible with natural languages and incompatible with
random texts".[31]
The linguist Jacques Guy once suggested that the Voynich manuscript text could be some little-known
natural language, written in the plain with an invented alphabet. The word structure is similar to that of
many language families of East and Central Asia, mainly Sino-Tibetan (Chinese, Tibetan, and Burmese),
Austroasiatic (Vietnamese, Khmer, etc.) and possibly Tai (Thai, Lao, etc.). In many of these languages, the
words have only one syllable; and syllables have a rather rich structure, including tonal patterns.
This theory has some historical plausibility. While those languages generally had native scripts, these were
notoriously difficult for Western visitors. This difficulty motivated the invention of several phonetic script
mostly with Latin letters but sometimes with invented alphabets. Although the known examples are much
later than the Voynich manuscript, history records hundreds of explorers and missionaries who could have
done it—even before Marco Polo's thirteenth century journey, but especially after Vasco da Gama sailed
the sea route to the Orient in 1499.

The first page includes two large red
symbols, which have been compared
to a Chinese-style book title.
The main argument for this theory is that it is consistent with all
statistical properties of the Voynich manuscript text which have
been tested so far, including doubled and tripled words (which have
been found to occur in Chinese and Vietnamese texts at roughly the
same frequency as in the Voynich manuscript). It also explains the
apparent lack of numerals and Western syntactic features (such as
articles and copulas), and the general inscrutability of the
illustrations. Another possible hint is two large red symbols on the
first page, which have been compared to a Chinese-style book title,
inverted and badly copied. Also, the apparent division of the year
into 360 days (rather than 365 days), in groups of 15 and starting
with Pisces, are features of the Chinese agricultural calendar ( jie qi,
節氣). The main argument against the theory is the fact that no one
(including scholars at the Chinese Academy of Sciences in Beijing)
has been able to find any clear examples of Asian symbolism or
Asian science in the illustrations.
In 1976, James R Child of the National Security Agency, a linguist
of Indo-European languages, proposed that the manuscript was
written in a "hitherto unknown North Germanic dialect".[32] He
identified in the manuscript a "skeletal syntax several elements of
which are reminiscent of certain Germanic languages", while the content itself is expressed using "a great
deal of obscurity".[33]
In late 2003, Zbigniew Banasik of Poland proposed that the manuscript is plaintext written in the Manchu
language and gave a proposed piecemeal translation of the first page of the manuscript.[34]
In February 2014, Professor Stephen Bax of the University of Bedfordshire made public his research into
using "bottom up" methodology to understand the manuscript. His method involves looking for and
translating proper nouns, in association with relevant illustrations, in the context of other languages of the
same time period. A paper he posted online offers tentative translation of 14 characters and 10
words.[35][36][37][38] He suggests the text is a treatise on nature written in a natural language, rather than a
code.
In 2014, Arthur O. Tucker and Rexford H. Talbert published a paper claiming a positive identification of 3
plants, 6 animals, and 1 mineral referenced in the manuscript to plant drawings in the Libellus de
Medicinalibus Indorum Herbis or Badianus manuscript, a fifteenth century Aztec herbal.[39] They argue th
these were from Colonial New Spain and represented the Nahuatl language, and date the manuscript to between 1521 (the date of the Conquest) to ca. 1576, in contradiction of radiocarbon dating evidence of th
vellum and many other elements of the manuscript. The analysis has been criticized by other Voynich
Manuscript researchers,[40] pointing out that—among other things—a skilled forger could construct plants
that have a passing resemblance to existing plants that were heretofore undiscovered.[41]

A floral illustration on page 32. The
colors are still vibrant.
The peculiar internal structure of Voynich manuscript words led William F. Friedman to conjecture that th
text could be a constructed language. In 1950, Friedman asked the British army officer John Tiltman to
analyze a few pages of the text, but Tiltman did not share this conclusion. In a paper in 1967, Brigadier
Tiltman said,
"After reading my report, Mr. Friedman disclosed to me his belief that the basis of the script
was a very primitive form of synthetic universal language such as was developed in the form of
a philosophical classification of ideas by Bishop Wilkins in 1667 and Dalgarno a little later. Itwas clear that the productions of these two men were much too systematic, and anything of the
kind would have been almost instantly recognisable. My analysis seemed to me to reveal a
cumbersome mixture of different kinds of substitution."[11]
The concept of an artificial language is quite old, as attested by John Wilkins's Philosophical Language
(1668), but still postdates the generally accepted origin of the Voynich manuscript by two centuries. In
most known examples, categories are subdivided by adding suffixes; as a consequence, a text in a particula
subject would have many words with similar prefixes—for example, all plant names would begin with
similar letters, and likewise for all diseases, etc. This feature could then explain the repetitious nature of thVoynich text. However, no one has been able yet to assign a plausible meaning to any prefix or suffix in th
Voynich manuscript.[42]
Hoax
The bizarre features of the Voynich manuscript text (such as the
doubled and tripled words), and the suspicious contents of its
illustrations support the idea that the manuscript is a hoax. In other
words, if no one is able to extract meaning from the book, then
perhaps this is because the document contains no meaningfulcontent in the first place. Various hoax theories have been proposed
over time.
In 2003, computer scientist Gordon Rugg showed that text with
characteristics similar to the Voynich manuscript could have been
produced using a table of word prefixes, stems, and suffixes, which
would have been selected and combined by means of a perforated
paper overlay.[43][44] The latter device, known as a Cardan grille,
was invented around 1550 as an encryption tool, more than 100
ears after the estimated creation date of the Voynich manuscript.Some maintain that the similarity between the pseudo-texts
generated in Gordon Rugg's experiments and the Voynich
manuscript is superficial, and the grille method could be used to
emulate any language to a certain degree.[45]
In April 2007, a study by Austrian researcher Andreas Schinner published in Cryptologia supported the
hoax hypothesis.[46] Schinner showed that the statistical properties of the manuscript's text were more
consistent with meaningless gibberish produced using a quasi-stochastic method such as the one described

The argument for authenticity is that the manuscript appears too sophisticated to be a hoax. While hoaxes o
the period tended to be quite crude, the Voynich manuscript exhibits many subtle characteristics which
show up only after careful statistical analysis. The question then arises as to why the author would employ
such a complex and laborious forging algorithm in the creation of a simple hoax, if no one in the expected
audience (that is, the creator's contemporaries) could tell the difference. Marcelo Montemurro, a theoretica
physicist from the University of Manchester who spent years analysing the linguistic patterns in the
Voynich manuscript, found semantic networks such as content-bearing words occurring in a clustered
pattern, and new words being used when there was a shift in topic.[47] With this evidence, he believes it
unlikely that these features were simply "incorporated" into the text to make a hoax more realistic, as most
of the required academic knowledge of these structures did not exist at the time the Voynich manuscript
was created. These fine touches require much more work than would have been necessary for a simple
forgery, and some of the complexities are only visible with modern tools.[48]
Glossolalia
In their 2004 book, Gerry Kennedy and Rob Churchill hint at the possibility that the Voynich manuscript may be a case of glossolalia,
channeling, or outsider art.[49]
If this is true, then the author felt compelled to write large amounts
of text in a manner which somehow resembles stream of
consciousness, either because of voices heard, or because of an urge.
While in glossolalia this often takes place in an invented language
(usually made up of fragments of the author's own language),
invented scripts for this purpose are rare. Kennedy and Churchill use
Hildegard von Bingen's works to point out similarities between theillustrations she drew when she was suffering from severe bouts of
migraine—which can induce a trance-like state prone to glossolalia
—and the Voynich manuscript. Prominent features found in both are
abundant "streams of stars", and the repetitive nature of the
"nymphs" in the biological section.
The theory is virtually impossible to prove or disprove, short of
deciphering the text; Kennedy and Churchill are themselves not
convinced of the hypothesis, but consider it plausible. In the
culminating chapter of their work, Kennedy states his belief that it is a hoax or forgery. Churchillacknowledges the possibility that the manuscript is a synthetic forgotten language (as advanced by
Friedman), or a forgery, to be preeminent theories. However he concludes that if the manuscript is genuine
mental illness or delusion seems to have affected the author.[49]
Historical decipherment claims
Since the manuscript's modern rediscovery in 1912 there have been a number of claims of successful
decipherment.

William Romaine Newbold
One of the earliest efforts to unlock the book's secrets (and the first of many premature claims of
decipherment) was made in 1921 by William Romaine Newbold of the University of Pennsylvania. His
singular hypothesis held that the visible text is meaningless itself, but that each apparent "letter" is in fact
constructed of a series of tiny markings only discernible under magnification. These markings were
supposed to be based on ancient Greek shorthand, forming a second level of script that held the real conten
of the writing. Newbold claimed to have used this knowledge to work out entire paragraphs proving theauthorship of Bacon and recording his use of a compound microscope four hundred years before van
Leeuwenhoek. A circular drawing in the "astronomical" section depicts an irregularly shaped object with
four curved arms, which Newbold interpreted as a picture of a galaxy, which could only be obtained with a
telescope.[11] Similarly, he interpreted other drawings as cells seen through a microscope.
However, Newbold's analysis has since been dismissed as overly speculative[50] after John Matthews Man
of the University of Chicago pointed out serious flaws in his theory. Each shorthand character was assume
to have multiple interpretations, with no reliable way to determine which was intended for any given case.
Newbold's method also required rearranging letters at will until intelligible Latin was produced. These
factors alone ensure the system enough flexibility that nearly anything at all could be discerned from themicroscopic markings. Although evidence of micrography using the Hebrew language can be traced as far
back as the ninth century,[51] it is nowhere near as compact or complex as the shapes Newbold made out.
Close study of the manuscript revealed the markings to be artifacts caused by the way ink cracks as it dries
on rough vellum. Perceiving significance in these artifacts can be attributed to pareidolia. Thanks to
Manly's thorough refutation, the micrography theory is now generally disregarded. [52]
Joseph Martin Feely
In 1943, Joseph Martin Feely published Roger Bacon's Cipher: The Right Key Found , in which he claimed
that the book was a scientific diary. Feely's method posited that the text was a highly abbreviated medievalLatin written with a simple substitution cipher. He also claimed that the writer of the manuscript was Roge
Bacon.[16]
Leonell C Strong
Leonell C. Strong, a cancer research scientist and amateur cryptographer, believed that the solution to the
Voynich manuscript was a "peculiar double system of arithmetical progressions of a multiple alphabet".
Strong claimed that the plaintext revealed the Voynich manuscript to be written by the 16th-century Englis
author Anthony Ascham, whose works include A Little Herbal , published in 1550. The main argumentagainst this theory is that its claimed offsetting cryptography runs counter to all the complex internal
structures presented by the text.
Robert S Brumbaugh
Robert Brumbaugh, a professor of medieval philosophy at Yale University, claimed that the manuscript wa
a forgery intended to fool Emperor Rudolf II into purchasing it. The text is Latin, but enciphered with a
complex, two–step method.[16]

John Stojko
In 1978, John Stojko published Letters to God's Eye[53] in which he claimed that the Voynich Manuscript
was a series of letters written in vowelless Ukrainian.[54] However, the date Stojko gives for the letters, the
lack of relation between the text and the images, and the general looseness in the method of decryption all
speak against his theory.[54]
Leo Levitov
Leo Levitov proposed in his 1987 book, Solution of the Voynich Manuscript: A Liturgical Manual for the
Endura Rite of the Cathari Heresy, the Cult of Isis,[55] that the manuscript is a handbook for the Cathar rite
of Endura written in a Flemish based creole. He further claimed that Catharism was a survival of the cult o
Isis.[56]
However, Levitov's decipherment has been refuted on several grounds, not least of being unhistorical.
Levitov had a poor grasp on the history of the Cathar, and his depiction of Endura as an elaborate suicide
ritual is at odds with surviving documents describing it as a fast.[56]
Likewise, there is no known link between Catharism and Isis.
Cultural impact
Many books and articles have been written about the manuscript. The first facsimile edition was published
in 2005, Le Code Voynich: the whole manuscript published with a short presentation in French.[57]
The manuscript has also inspired several works of fiction, including The Book of Blood and Shadow by
Robin Wasserman, Time Riders: The Doomsday Code by Alex Scarrow, Codex by Lev Grossman, PopCo
by Scarlett Thomas, Prime by Jeremy Robinson with Sean Ellis, The Sword of Moses (2013) by Dominic
Selwood, The Return of the Lloigor by Colin Wilson, Datura, or a delusion we all see (Finnish version
2001) by Leena Krohn, "Assassin's Code" by Jonathan Maberry and "The Source" by Michael Cordy.
Between 1976 and 1978,[58] Italian artist Luigi Serafini created the Codex Seraphinianus containing false
writing and pictures of imaginary plants, in a style reminiscent of the Voynich manuscript.[59][60][61]
Contemporary classical composer Hanspeter Kyburz's 1995 Chamber work The Voynich Cipher
anuscript, for chorus & ensemble is inspired by the manuscript.[62]
