A Deterministic Phonetic-Functional Resolution of the Voynich Manuscript (Beinecke MS 408): Complete Method, Correspondence Table, and Empirical Demonstration

This deposit presents the complete phonetic-functional resolution of the Voynich Manuscript (Beinecke MS 408) through the EVA-ZAMNA system, a closed deterministic linguistic architecture that establishes one-to-one phonetic correspondences between the manuscript’s graphic units and historically documented phonemes from the medieval vernacular Italian register of the Naples-Salerno region (14th–15th centuries).The package comprises five documents: (1) the main study, presenting the theoretical framework, state of the art, historical context, and formal description of the method; (2) the EVA-ZAMNA Table in its definitive closed form, with glyph-by-glyph phonetic justification; (3) the complete canonical translation of folio f82r (balneological section, Currier Language B), showing all five layers of the protocol for 32 lines and 13 labels; (4) the integrated narrative reading of folio f82r, demonstrating text-image coherence with the Salernitan hydrotherapy tradition; and (5) the text-image coherence analysis of folio f1v (herbal section, Currier Language A), providing cross-manuscript validation through lexical differentiation between sections.This work is the result of approximately three years of research and one year of intensive formalization, conducted by two independent researchers. The morpho-syllabic method was formally registered in October 2025. The research process involved the analysis of over 500 working documents, more than 2 million words processed, and over 5,000 hours of dedicated research. Artificial intelligence was not used to translate the manuscript or to generate hypotheses; it was employed exclusively as a tool for documentary formalization and academic structuring.The EVA-ZAMNA system is explicitly falsifiable, fully reproducible, and methodologically closed. Any independent researcher can apply the published table to the Voynich corpus and verify the results. The manuscript is identified not as a cipher or a hoax, but as a functional technical manual of women’s medicine, written in a private phonetic system during a period of systematic persecution of female medical practice in medieval Europe.
