Abstract

The Voynich Manuscript remains one of the most enigmatic artifacts in the history of writing. Despite over a century of decipherment attempts, no hypothesis has conclusively demonstrated that the text represents a natural language, a classical cipher, or a purely random hoax. This paper analyzes a recent proposal by Michael Greshko (2025), who introduces the experimental cipher system “Naibbe” as a proof of possibility that a manual algorithmic procedure could generate text with statistical properties similar to those of the Voynich Manuscript. It is argued that this result shifts the ontology of the manuscript: from a “hidden language” toward a “symbolic machine,” that is, an artifact whose meaning resides primarily in the generative procedure rather than in the text itself. This reinterpretation situates the Voynich Manuscript as a liminal object between language, cipher, and pre-modern symbolic computation.

1. Introduction

The Voynich Manuscript, radiocarbon-dated to the 15th century and currently preserved at Yale University, contains approximately 38,000 words written in an unknown script, accompanied by botanical, astrological, and alchemical illustrations. Since its rediscovery in the early 20th century, it has been the subject of intense study by cryptographers, linguists, historians, and, more recently, machine learning systems.

Prevailing hypotheses fall into three main categories: (i) the manuscript encodes an unknown natural language; (ii) it is a cipher based on a known language; or (iii) it is a meaningless construction, possibly an elaborate hoax. None of these positions, however, has achieved decisive empirical validation.

This paper argues that Greshko’s recent work shifts the problem space: the Voynich Manuscript should not primarily be understood as a text, but as the output of a procedure. In this sense, it is more productively analyzed as a symbolic machine.

2. The Naibbe cipher as a proof of possibility

Greshko introduces “Naibbe,” an experimental system that uses historically plausible sources of randomness (dice and playing cards) to transform an input text (Latin or medieval Italian) into sequences of artificial glyphs. The system operates through probabilistic segmentation of the input, followed by substitution via weighted tables designed to mimic the statistical distributions observed in the Voynich Manuscript.

Naibbe does not reproduce the manuscript nor does it decipher it. Its significance lies in demonstrating that:

  1. It is possible to generate text with Voynich-like statistics without pure randomness.

  2. Such a process is feasible using only medieval-level technology.

  3. The resulting output exhibits linguistic-like structure without necessarily containing internally readable semantics.

This establishes a historical and computational proof of possibility for a procedural hypothesis.

3. The Voynich Manuscript as a liminal object

On this basis, the manuscript can be situated outside traditional categories:

CategoryApplicability
Natural languageunlikely
Classical cipherinsufficient
Random noiseruled out
Trivial hoaximplausible
Procedural symbolic systemplausible

The manuscript is not merely a text but a static trace of a dynamic generative process. Its semantic content, if any, is displaced from the manuscript itself into the procedure that produced it.

This places the Voynich Manuscript closer to formal automata, generative systems, or symbolic machines than to ordinary human languages.

4. Theoretical implications

This reinterpretation has several implications:

  • For linguistics: it challenges the assumption that linguistic structure necessarily implies natural language.

  • For cryptography: it shows that not all regularity is decodable as a classical cipher.

  • For the history of computation: it suggests the existence of proto-computational symbolic practices prior to modern formalization.

The Voynich Manuscript thus appears as an artifact embodying a form of manual symbolic computation — procedural, formal, and generative, though not algorithmic in the modern sense.

5. Conclusion

Greshko’s study does not solve the Voynich Manuscript, but it fundamentally alters its epistemological status. The manuscript becomes not merely an undeciphered text, but a generated object whose intelligibility depends less on translation than on procedural reconstruction.

The Voynich Manuscript is therefore not only a problem of decipherment, but evidence that late medieval culture may have developed symbolic practices capable of producing language-like systems without relying on an underlying language.
