No text, but a visual code

[Urtx13]

Hi Antonio and all,


Thank you for opening this thread. I agree that looking at the Voynich manuscript as a symbolic, possibly astronomical or agronomic code makes a lot of sense, especially if we move beyond assuming it must represent a phonetic language.

To contribute to this direction, I’ve recently completed a fully reproducible computational analysis of the botanical folios using entropy, topic modeling, and synthetic lunar phases. Unlike intuitive symbol reading, this approach statistically tests for hidden structure. The results were compelling:

• A supervised classifier predicted four internal “phases” across folios with 96.5% accuracy.
  
• A 1,000-run permutation test confirmed the structure is not random (p < 0.001). Not a bias.
  
• The pattern was validated against real flowering data from plants, showing ~65% alignment using a ±1 phase margin.
  
• Topic autocorrelation and FFT revealed regular harmonic peaks, suggesting a latent cyclic rhythm.
  
• These cycles appear both globally across the manuscript and within individual pages, indicating a multi-layered structure.
  

My working hypothesis is that the manuscript encodes a symbolic lunisolar calendar tied to Mediterranean agricultural cycles, particularly the phases of planting, growth, bloom, and harvest. The evidence suggests that the “text” may represent a calendrical and agronomic code rather than conventional language.

It doesn’t decode the script, but shows that, statistically, the content behaves like a ritual calendar system rather than random prose.

The entire project is fully open and reproducible, with fixed seed 1405. The code and data are available here:
