What Exactly Is The Voynich Manuscript?

This singular artifact is a handwritten book, or codex. It is composed of vellum (animal skin) pages, totaling around 240, though some appear to be missing.

It is currently housed at Yale University, specifically in the Beinecke Rare Book & Manuscript Library. It is cataloged under the item name MS 408.

The book’s true mystery lies in its content. It is filled with elaborate, colorful illustrations of subjects that are often unidentifiable. Strange plants, astrological diagrams, and small, naked figures dominate its pages.

Alongside these drawings is a script that has never been identified. This unique alphabet, dubbed “Voynichese,” appears nowhere else in the historical record.

Its name comes from Wilfrid Voynich, a rare-book dealer who acquired the codex in 1912 from a Jesuit college in Italy. Its history before that point is murky, though it is associated with figures like the 17th-century alchemist Georg Baresch.

Baresch himself seemed stumped, describing it in a letter as a “Sphinx” that was taking up space uselessly in his library.

The text flows from left to right, with distinct words and characters. However, no one knows what language it represents or what code it uses. It is a true linguistic anomaly.

What Does Carbon Dating Tell Us About Its Age?

For decades, many believed The Voynich Manuscript was an elaborate forgery, perhaps created by Wilfrid Voynich himself to secure a high price.

This theory was put to the test scientifically. In 2009, the University of Arizona was given permission to perform Accelerator Mass Spectrometry (AMS) radiocarbon dating on tiny samples from four different pages.

The results were definitive and surprising. The tests concluded with 95% certainty that the vellum parchment was made between 1404 and 1438.

This proved the materials of the book were from the early 15th century. It was not a modern hoax by Voynich.

Further analysis by the McCrone Research Institute in Chicago examined the inks and paints. They found the pigments were consistent with materials and techniques common in the Renaissance period.

Therefore, scientific evidence firmly places the book’s creation in the early 1400s. This artifact is a genuine medieval product, which only deepens the mystery of its unreadable text.

What Bizarre Content Lies Within Its Pages?

The manuscript is generally divided by scholars into six distinct sections based on the nature of its illustrations. Each section presents its own unique set of puzzles.

1. The Herbal Section: This is the largest part of the book. Each page features a large drawing of a plant. The problem is that almost none of these plants can be matched to any known species on Earth.

They appear to be composite plants, combining roots, leaves, and flowers from different species, or perhaps they are complete fantasies.

2. The Astronomical Section: This part contains circular diagrams and charts. Many resemble astrological charts, complete with illustrations of suns, moons, and constellations.

Some of these charts appear to be variations of the traditional zodiac. Yet, their exact meaning or system remains completely opaque to modern astrologers and astronomers.

3. The Balneological Section: This is perhaps the most famous and strangest section. It features intricate illustrations of small, naked figures, mostly female, bathing in pools or tubs.

These pools are connected by a complex network of “plumbing” or tubes. The scenes have no known parallel in medieval art and their purpose—whether anatomical, ritualistic, or allegorical—is unknown.

4. The Cosmological Section: These are more circular diagrams, but their meaning is even less clear. They feature abstract patterns, “rosettes,” and possible maps that defy geographical identification.

5. The Pharmaceutical Section: This section shows arrays of objects that look like medicine jars or containers. They are drawn in margins alongside small illustrations of plant parts, suchs as roots or leaves.

It is speculated this could be a list of ingredients or recipes for herbal remedies.

6. The Recipes Section: This is the final and only unillustrated section. It consists of solid blocks of text, written in Voynichese. Stars in the margins seem to break the text into small paragraphs.

Many believe these are instructions or “recipes” that correspond to the other sections, but without a translation key, this remains pure conjecture.

Why Has The Voynich Manuscript Resisted All Deciphering?

The greatest military and academic minds have tried and failed to unlock The Voynich Manuscript.

During World War II, top American and British codebreakers, including men who successfully cracked Japanese and German codes, studied the manuscript. They all came away empty-handed.

The difficulty is twofold: we do not know the underlying language, and we do not know the “cipher” or method used to encode it (if any).

It is not a simple substitution cipher, where one symbol equals one letter. Statistical analysis shows that the text has features of a real language.

For example, the word frequency in Voynichese follows “Zipf’s Law.” This is a linguistic principle stating that the most frequent word in any language will appear about twice as often as the second most frequent, three times as often as the third, and so on.

The Voynich Manuscript obeys this law perfectly. Random gibberish does not. This strongly suggests the text is not meaningless scribbling; it has structure.

It also displays entropy—a measure of information density—that is similar to natural languages like English or Latin.

Yet, it has its own strange rules. Some words are repeated two or three times in a row, which is highly unusual. Certain characters seem to appear only at the beginning of words, while others appear only at the end.

Which Theories Dominate the Discussion in 2025?

The lack of answers has created a vacuum filled by fascinating, and sometimes wild, theories. These are the four most prominent explanations circulating today.

Theory 1: An Enciphered Text

This is the most popular theory. It posits that the text is a known language (like Latin, German, or Hebrew) that has been obscured by a complex cipher.

The cipher would have to be incredibly robust. Perhaps it was a “polyalphabetic cipher” (invented in the 15th century) or a unique system using a special “grille” or codebook.

The problem is that no one has found the key. Every attempt to apply a known cipher has resulted in gibberish.

Theory 2: A Lost Natural Language

A compelling argument suggests Voynichese is not a code at all. It may simply be a lost or unknown language written in its own unique alphabet.

If a language family died out or was isolated, its written form could be lost to history. The Voynich Manuscript might be the last surviving example.

This would explain why it follows linguistic rules (like Zipf’s Law) but cannot be translated. We have no “Rosetta Stone” to link it to a known language.

Theory 3: An Elaborate Medieval Hoax

This theory argues the book is a masterpiece of deception. The carbon dating proves the book is old, but it does not prove the content is meaningful.

A clever 15th-century trickster could have created the text and illustrations to sell to a wealthy, gullible patron (like Emperor Rudolf II, a known owner).

The creator could have generated the “language” using a simple algorithm or set of rules that mimics real language but contains no actual message.

Theory 4: An Artificial or Constructed Language

A fourth idea bridges the gap between a cipher and a hoax. The manuscript could be an “artificial language,” like Esperanto or Klingon, but created 600 years earlier.

Perhaps a philosopher or mystic tried to create a universal language to express complex ideas. This would explain its unique structure and vocabulary.

This doesn’t mean it’s meaningless, but it means it was invented, making translation impossible without the creator’s grammar and dictionary.

Can Artificial Intelligence Finally Crack the Code?

With the rise of machine learning and neural networks, researchers turned AI loose on The Voynich Manuscript. The results, as of 2025, have been promising but ultimately inconclusive.

In 2018, researchers at the University of Alberta used AI to analyze the text. Their algorithm suggested the underlying language was Hebrew, obscured by a specific type of substitution cipher.

This generated huge excitement. However, other computational linguists and Hebrew scholars quickly challenged the findings.

They argued the AI’s “translations” were nonsensical and were likely the result of the AI finding patterns where none existed.

The problem is that AI is a powerful tool for pattern recognition. It can find subtle linguistic structures that humans miss.

But AI lacks historical and cultural context. It cannot understand why a 15th-century author would draw bizarre plants or bathe small people in green tubes.

Without this context, the AI is just guessing. While it confirms the text is non-random, it has not yet provided a translatable solution. The mystery persists, even in the age of algorithms.

A Quick Guide to the Dominant Voynich Theories

To clarify the debate, here is a simple breakdown of the leading hypotheses.

Theory	Basic Premise	Supporting Evidence	Major Weakness
Cipher	A known language (e.g., Latin) hidden by a code.	Text has statistical structure; ciphers were common.	All decryption attempts have failed.
Lost Language	A real, but extinct, language in its own script.	Obeys Zipf’s Law; feels like a natural language.	No other trace of this language exists.
Hoax	Meaningless text designed to look real and valuable.	Bizarre, unidentifiable content; financial motive.	Text is too complex and structured for a simple hoax.
Artificial Language	An invented language (like Esperanto) for a specific purpose.	Explains the unique structure and “unnatural” rules.	Impossible to translate without the inventor’s key.

Conclusion: The Enduring Allure of the Unsolvable

The Voynich Manuscript is more than just an old book. It is a mirror reflecting our own desire to know, to solve, and to understand.

Science has told us when it was made, but it has not told us why. Linguistics has told us it has structure, but not what that structure means.

Every page taunts the observer with information that is clearly visible but completely inaccessible. It is a message in a bottle from 500 years ago, and we cannot find the corkscrew.

Perhaps one day, a breakthrough in AI, a lucky historical find, or a new linguistic insight will provide the key.

Until that day, The Voynich Manuscript remains the undisputed champion of cryptography. It is a beautiful, baffling, and ultimately human mystery.

Frequently Asked Questions

Q: Where can I see The Voynich Manuscript in person?

A: The manuscript is held in the Beinecke Rare Book & Manuscript Library at Yale University. It is a delicate artifact and is not on permanent public display, but it is available to qualified researchers by appointment. The entire book is digitized in high resolution for public viewing online.

Q: Who was Wilfrid Voynich?

A: He was a Polish-Samogitian revolutionary who fled his homeland and became a prominent rare-book dealer in London and New York.

He acquired the manuscript in 1912. He was fascinated by it and promoted its study, but he was never able to sell it.

Q: Has any part of the manuscript been translated?

A: No. Despite countless claims over the decades, no proposed translation has ever been verified or gained acceptance in the academic community. Many “solutions” turn out to be the result of pareidolia (seeing patterns in randomness) or flawed methodology.

Q: Could it be an alien artifact?

A: While a popular theory in speculative fiction, there is zero evidence for this.

The carbon dating proves the vellum (animal skin) and the chemical analysis of the ink prove the physical components of the book are entirely earthly and consistent with 15th-century European technology.

Q: What is the most likely solution?

A: Most serious researchers are divided between the “cipher” and “lost language” theories.

The fact that the text follows linguistic laws (like Zipf’s Law) strongly suggests it is not a random hoax. It almost certainly contains meaning, but the system for that meaning is lost to us.
