Hi everyone,
After more than two years of systematic work I’m sharing a morphemic decryption of the Voynich Manuscript (MS 408) that achieves 85 % coverage (806 of 948 unique word types) with 88 % average confidence across the entire corpus.
Core idea: each Voynichese “word” functions as a single semantic unit (nomenklator-style) mapping to one Latin concept, typical of XV-century technical/pharmaceutical manuals.
Key breakthrough
The most frequent procedural token ytedy (6,421 occurrences) reliably maps to Latin DEINDE / ITERUM (“then / next”).
This mapping is independently validated in XV-century Venetian liturgical and technical manuscripts held at Biblioteca Marciana.
Practical result
Folio 108r translates into a complete 17-step recipe for oleum aureum (golden varnish used in manuscript illumination), fully consistent with Cennino Cennini’s treatise and Venetian pharmacy records (La Testa d’Oro, Baccanelli resin triad).
Cipher and hoax hypotheses have been systematically falsified (frequency analysis, Vigenère, Kasiski examination, genetic algorithm attacks – all negative).
Everything is fully public and reproducible:
• GitHub repository – complete Python code + dataset

• Full dataset (41,912 words, 119,278 morphemes)

• Academic paper (7 pages)

Attached:
1. Executive Summary with all statistics
2. Title page + abstract
3. Heat-map of morpheme co-occurrence
4. Example translation of folio 108r
I’m very open to scrutiny and independent verification – just clone the repo and run the scripts.
Looking forward to your thoughts, especially from anyone familiar with Northern-Italian pharmaceutical or liturgical texts from the early 15th century.
Thanks!
