Zlatko (Serbian mathematician) informed me through Skype enthusiastically: " Eureka! I have finally decrypted Voynich". Later, in email he enclosed a sheet with description of the process– from algorithms to formulas and codes he employed…It is third Zlatko's 'finally' decryption, time-consuming on details to scrutinize and, well, a nice job if you foresee whatever it is, it will eventually be a failure. Why? The matter is that Voynich code is a mystificated nonsense.
So none algorithms and semantic matrix may be applied to decrypting it. I know many zealots amongst mathematicians and cryptolinguists would eat me alive for these words as they have not yet lost the hope of being awarded to Nobel for this. Nevertheless, I am sure it is actually impossible to do.

First, to all who reading it, what Voynich manuscript is.
" The year is 1912. The successful dealer in old books Wilfrid M. Voynich acquires a number of priceless mediaeval manuscripts from an undisclosed location in Europe. Among these is a parchment codex of 234 pages, written in an unknown script. The manuscript is profusely illustrated, with drawings, among others, of plants and astronomical patterns. It appears to be a scientific work from the middle ages, but due to its unknown script, the contents are a complete mystery.











Voynich took the MS to the United States and started a campaign to have its text deciphered. Now, almost 100 years later, the Voynich manuscript still stands as the most elusive enigma in the world of cryptography. Not a single word of this 'Most Mysterious Manuscript', written probably in the first half of the 15th Century, can be understood.
Attached to the manuscript was a letter in Latin dated 1666 from Johannes Marcus Marci of Kronland, once rector of the Charles University of Prague, to the learned Jesuit Athanasius Kircher in Rome, offering the manuscript for translation and mentioning that it had once been bought by Emperor Rudolf II of Bohemia (1552-1612) for 600 gold ducats. The letter further mentioned that it was believed that the author of the MS was Roger Bacon (the Franciscan friar who lived from 1214 to 1294).
Another early owner of the MS was identified by Voynich when, on the lower margin of the first folio, under special illumination, the erased signature of Jacobus de Tepenec was found. Tepenec was one of Emperor Rudolf's courtiers and the director of his botanical gardens and he must have owned the manuscript between 1608, when he received his title "de Tepenec", and 1622, when he died. The MS has changed hands sevetal times, and apart from some minor gaps in our knowledge its path from the court of Rudolf II to its final resting place, the Beinecke Rare Book and Manuscript Library of Yale University, can be traced fairly accurately.



The MS became famous when, in the 1920's, William Romaine Newbold proposed a spectacular decipherment with which he meant to prove that it was indeed written by Roger Bacon, and that Bacon had not only dreamt of, but actually built microscopes and telescopes.



When this 'solution' of the MS was disproven by John M. Manly in 1931, the MS gradually became a pariah in world of mediaeval studies. In the 1940's and 1960's the eminent cryptanalyst William F. Friedman made several valiant attempts at deciphering the MS, aided by groups of experts, but also he did not find any solution. (с) http://www.voynich.nu/s_intro.html#intro

Take a detailed look now on a attempts that had been tried to decrypt it. Read:
“When Newbold first attacked the MS for decipherment, he realized that he needed to find a key which would allow him to understand how the MS was enciphered. On the last page of the MS was written a single sentence:
“michiton oladabas multos te tccr cerc portas”
Disregarding the obvious nulls used in the sentence (ton ola tetccr cerc) and exchanging the “o” in “multos” for “a”, the intelligible Latin sentence emerges:
“michi dabas multas portas”
translating into English, “To me thou gavest many gates.”
Counting the number of letters in the sentence reveals it to be 22. Newbold then adapted the Latin alphabet to it omitting the letter “k”, replacing “x” with “v” and produced the first form of the cipher alphabet used by Bacon:
m i c h i d a b a s m u l t a s p o r t a s
a b c d e f g h i l m n o p q r s t u v y z
Here is what makes Newbold’s qualifications for decipherment of the MS so felicitous. Newbold understood that a major clue was to be found in the word “portas”, in that its interpreted cabalistic meaning of “gates” would be the secret to the clarification of the Key. Newbold knew that Bacon was well acquainted with the Cabala and would have used such a plan in his Key, for in Bacon’s Epistle on the Nullity of Magic, where he details several ciphering systems, the sixth such system is called, “The Kabbalah of the Nine Chambers”. From Newbold’s footnotes we find the following:
“In Cabalistic philosophy the universe consists of God’s
thought; thought is expressed in speech; speech is composed of
letters; hence the Letters are the ultimate constituents of Things.
The ”gates” are the 231 biliteral combinations of the Hebrew
Ietters (doubles omitted; 231 permutated pairs added by later
writers); they represent the primary combinations of the highest
manifestations of the divine Being which are at once the forces
which make other things, the material of which they are made, and
the channels through which the divine energy streams forth into
the lower world. A single quotation from the Sepher Yezirah, will
suffice:
He combined (the Letters), weighed them, exchanged them,
Aleph with all and all with Aleph, Beth with all and all with Beth,
and they go (each) all the way around (the Alphabet). And they are
found (comprised) in 231 gates, and everything formed and
everything uttered is found to proceed from one Name.”
off-top : this text unwillingly reminded me a scene from Aronofsky's “Pi” with a cliché conception of a physical world digitally administered, with an only difference in key number 215 vs 231
Thus, “gates” not only implies a cipher of many steps, but it reveals that the gates are the channels through which alphabetic values are conveyed from Key Sentence to the 484(admitting doubled letters) biliteral symbols.
With the Key now in hand, Newbold began to approach the actual text of the MS. With more cabalistic associations appearing, Newbold discovered 22 distinct symbols, among these 22 were recognized the 15 signs that composed the Greek system of shorthand. Bacon was quite familiar with this Greek system, having written a grammar including such information, and reading from the eighth chapter of Bacon’s Epistle on the Nullity of Magic, we will find the great significance he placed on secret writing, and particular reference to the shorthand system:
“The man is insane who writes a secret in any other way than one
which will conceal it from the vulgar and make it intelligible only
with difficulty even to scientific men and earnest students. On this
point the entire body of scientific men have been agreed from the
outset, and by many methods have concealed from the vulgar all
secrets of science. For some have concealed many things by
magic figures and spells, others by mysterious and symbolic
words. For example, Aristotle in the Book of Secrets says to
Alexander, ‘O Alexander, I wish to show you the greatest secret of
secrets; may the Divine Power help you to conceal the mystery
and to accomplish your aim. Take therefore the stone which is not
a stone and is in every human being and in every place and at
every time, and it is called the Egg of the Philosophers, and
Terminus of the Egg.’ Innumerable examples of the kind are to be
found in many books and divers sciences, veiled in such
terminology that they cannot be understood at all without a
teacher. The third method of concealment which they have
employed is that of writing in different ways, for example, by
consonants alone, so that no one can read it unless he knows the
words and their meanings. In this way the Hebrews and the
Chaldaeans and Syrians and Arabs write their secrets. Indeed, as
a general thing, they write almost everything in this way, and
therefore among them, and especially among the Hebrews.
Important scientific knowledge lies hidden. For Aristotle in the
book above mentioned says that God gave them all scientific
knowledge before there were any philosophers, and that from the
Hebrews all nations received the first elements of philosophy. .. .
In the fourth place, concealment is effected by commingling letters
of various kinds; it is in this way that Ethicus the astronomer
concealed his scientific knowledge by writing it in Hebrew, Greek,
and Latin letters in the same written line. In the fifth place, certain
persons have achieved concealment by means of letters not then
used by their own race or others but arbitrarily invented by
themselves; this is the greatest obstacle of all, and Artephiushas
employed it in his book On the Secrets of Nature. In the sixth
place, people invent not characters like letters, but geometrical
figures which acquire the significance of letters by means of
points and marks differently arranged; these likewise Artephius
has used in his science. In the seventh place, the greatestdevice
for concealment is that of shorthand, which is a method of noting
and writing down as briefly as we please and as rapidly as we
desire; by this method many secrets are written in the books of the
Latin-using peoples. I have thought fit to touch upon these
methods of concealment because I may perhaps, by reason of the
importance of my secrets, employ some of these methods, and it
is my desire to aid in this way, at least you, to the extent of my
ability.”
The other 7 shorthand signs of Newbold’s discovery all fit the same general character of the first 15, and were used by Bacon to fill out the Greek shorthand, which was lacking expression.
Newbold continued by employing the biliteral method to the converted shorthand, and found that frequency analysis of the resultant alphabet revealed it to be characteristic of Latin. The final stage in the process of decipherment was the anagramming process. The process of anagramming texts was probably the most popular method of the day used for concealing messages, and the necessity of concealment was due to political or ecclesiastical reasons of the time, making the information unpropitious for pronouncement. It is known that the Cabalists were professed anagrammatists, and the third part of their art ? themuru (changing) dealt with transposition and recombination of the letters of words for mystical interpretation. The fact that it was also a tradition among the “orders” can be witnessed in the works of von Bingen, and certainly in the Abbe N. De Montfaucon De Villars’ “Comte De Gabalis” (Quodtanto impendio absconditur etiam solummodo demonstrare destruereest – Tertullian). It was even continued with the likes of Galileo (Haec immatura a me jam frustra leguntur – oy), Tycho Brahe (who also was at the court of Rudolph), Johannes Kepler, and many others.
At last, the plain text began to emerge, and without going too far afield for the letters of anagrammed text. The letters to be rearranged occurred in pairs next to one another, either indirect or reverse order, and only relatively infrequently did Newbold have to go as far as three or four words ahead in order to fill in the plaintext.
What Newbold discovered in the text was absolutely astonishing? enough to gather a lot of attention from the scientific community. The biological drawings in the text were described asseminiferous tubes, the microscopic cells with nuclei, and even spermatozoa. Among the astronomical drawings were the descriptions of spiral nebulae, a coronary eclipse, and the comet of 1273. One of the more baffling things about this was that many of the drawings of plants, and of the galaxies appeared to have been invented. There was no doubt that if Bacon were the author of such a text, he must have had some way of obtaining the information. For instance, Newbold’s translation of the caption near the drawing of the nebula of Andromeda (which clearly shows its spiral characteristics), gave its location by the following:
“In a concave mirror I saw a star in the form of a snail….between the
navel of Pegasus, the girdle of Andromeda, and the head of Cassiopea”.
Now, Bacon is credited with the invention of the magnifying glass, but it should be certain that he did not invent the telescope or the microscope as many at the time of this discovery conjectured. The “concave mirror” is probably the single most important clue here. Many of the later prominent Renaissance figures would not only describe similar visions of travel to distant places, several also included such “shewstones” as their viewing apparatus. In the works of Dee, Kircher, and even the more famous Nostradamus, one will find reference to such a device, and in each case these individuals recorded the experience of visions associated with it. Some of their descriptions were later proven to be precise. The actual knowledge pertaining to the use of a device such as this is probably now lost, but in any case it is most worthy of mention considering the circumstances. Let us now turn to some of the objections to Newbold’s decipherment of the MS.

NEWBOLD’S DETRACTORS – AND HIS VALIDATION

Initially, upon the announcement of his findings in1921, Newbold received some praise for his work. Even John M. Manly, a military intelligence cryptanalyst, wrote a favourable review in Harper’s Magazine. But, this was not to last very long, and soon the attacks proceeded. The first of such attacks came from research chemists who stated that the rough vellum surface upon which the MS was written had caused the ink to break up into spots and shadings with age. This break up of characters, they stated, was what Newbold had actually seen when deciphering the shorthand characters.
This criticism that the ink had merely broken up into spots and shadings due to age was unfounded due to the fact that many documents nearly as aged as the Voynich MS, with comparable ink, do not display cracking similar to the individual characters in the MS. Also, if the arrangement of characters was due to this breaking up of the ink, certainly more than 22 individual shorthand symbols would have been discovered by Newbold.
The next attack was concerned with the biliteral method of Newbold’s decipherment. Cryptographers stated that by Newbold’s methods, Bacon could not have enciphered the text to begin with. But, Newbold clearly detailed the enciphering process, and revealed that Bacon did not use “orthodox” methods of enciphering to which the cryptographers were accustomed.
Attacked most heavily of all was the anagramming process Newbold used. These detractors maintained that one could anagram any text into anything one chose, and that this method would not have followed the qualifications of a “good” cipher, in that the first quality of any “good” cipher is that it must convey its message with absolute certainty. Newbold’s anagramming process did NOT use “blocks of 55 to 110 characters”, as had been put forth by these detractors, on the contrary, it can be shown from his own notes that he was very careful in his observations:
“The only indication that the recomposition is correct is the regular
appearance, at intervals of NOT more than three or four words, of
letter groups suggesting words appropriate, in syntax and logic, to
the preceding text. If they fail to appear, if one is driven to
arbitrary choice in order to make sense, the recomposition is
probably wrong.”
I have observed this misrepresentation of facts of Newbold’s decipherment in a number of works (David Kahn’s gigantic work titled The Codebreakers immediately comes to mind) and find it quite an admonition to any other statements made by such authors. The fact that his detractors used such methods to anagram texts into any messages they seemed fit ? designed to expose flaws in Newbold’s decipherment ? is clearly disinformation. Newbold, by HIS method, equally tried other texts of the period including works of Bacon which were not meant to be in cipher, and while he could form Latin words for a time, he was soon left with unmanageable groups of consonants, and discontinued the experiment, as Latin requires between 40 and 50 percent vowels.
It wasn’t until after Newbold’s death in 1926 that more serious assaults would come. In 1931 John Manly (who earlier gave praise) published a 47 page article in Speculum Magazine of what he called “a detailed analysis” that attempted to make Newbold’s work seem entirely worthless. But many more would hinge their deprecations on Newbold’s interpretation of the drawings contained in the MS. Most said that the biological pictures were cabalistic (they certainly were!), symbolical, vague, and capable of various interpretations. I must note that I personally have given these biological drawings to persons well credentialed in the field of Biology, and asked them to give me an explanation of what they see in them. In every instance, and without any prior knowledge of the MS, they have given descriptions that very closely resemble the deciphered interpretations of Newbold.
Other assailants made particular note of the drawing that represented the nebula Andromeda. Based on the fact that the spiral nebula in Andromeda lies edge on to earthly observers, Bacon would have had to have an incredibly powerful telescope to view such a thing. But, as we have noted, no one was really claiming that he did.
It may be deduced from these painstaking onslaughts that maybe these assailants felt it was necessary to hide the true nature of the work. In Manly’s 1931 article, he blatantly reveals his real concerns with the warning to all that, “these results (of Newbold’s) threaten to falsify to no unimportant degree, the history of human thought.” Kahn, in The Codebreakers, devotes several pages to the MS decipherment, and groups Newbold into a category he later describes as oddballs and lunatics who believe in such things as water witching.
Of course, the depreciated Newbold decipherment did not discourage others from attempting to figure out the MS, and a few of the arguments put forward may have been somewhat conceivable. In 1944, Professor Hugh O’Neil, a botanist at the Catholic University of America, offered evidence that the MS could not have been written before 1493. He observed that the drawings in the MS include the likes of the common sunflower, and Capsicum, both plants native to the Americas which according to him, were unknown to Europeans before the return of Columbus from his second voyage. We needn’t go into the Columbus discovery here, as historically it is well known that he was hardly the first to venture to the Americas.
Not long after O’Neil’s observations, Dr. Leonell Strong, a cancer research scientist and amateur cryptographer, took on the project of deciphering the MS. Fancifully boasting that he could “unravel” the secret of any cipher, Strong said that the solution to the MS cipher was a “peculiar double system of arithmetical progressions of a multiple alphabet”. Even here, there was a great similarity to Newbold’s system, but Strong altogether bombastically stated that the plaintext revealed the MS to be written by the 16th century English author Anthony Ascham, whose works include A Little Herbal, published in 1550. Although the MS does contain one section resembling an herbal, it is unknown where the author of A Little Herbal would have obtained such literary and cryptographic knowledge.
The speculation of William F. Friedmann, another military cryptographer, was that the MS was actually a text in an artificial language, and may have held some merit if it were not for the fact that he was also responsible, and instrumental in the demolition of Newbold’s theory (again, after Newbold’s death). But, he, too never went any further than this simple hypothesis. Many others have invented their own versions of decipherment of the MS, but all of them fall short of making anything intelligible out of the mysterious characters. To the cryptographic orthodoxy, the MS is still “undeciphered”. I believe many have merely taken the disparaging words of others as proof that the Newbold solution is bogus, without actually examining the specifics. Had Newbold been an amateur with nothing but this decipherment for credentials, it would certainly raise some doubt. But, Newbold indeed practised his techniques on similar manuscripts such as the Tironian signs of the so-called Vatican Document (which I won’t detail here as it would necessitate the space of an entire article in itself) and many others.

It is most probable though, that the Voynich MS actually cost Newbold his health, both physically and mentally .In the latter days of his work on the MS he began to grow weary and would often restructure his entire method without any sense of reason. Still, the heart of Newbold’s inspiration lies in his initial work on the MS, and there has not been anyone since who has even come close to the original genius of his solution to “the most mysterious manuscript in the world”.

In 2004 an English professor Gordon Rugg by usung Grill method is supposed to cracked a Voynich code, then announced it to be a pseudo-meaningful, showing a persuasive proof of how it may be traced.


But I don't think that numerous next more persuasive proofs may stop such enthusiastic guys like you Zlatko.
