Deciphering the Voynich Manuscript (Beinecke MS 408): A Three-Tier Anagrammatic Italian Cipher and the Medical Legacy of Pietro da Eboli

Deciphering the Voynich Manuscript (Beinecke MS 408): An Anagrammatic Italian Cipher and the Medical Legacy of Pietro da Eboli Summary:This paper presents a verified solution to the Voynich Manuscript (MS 408), demonstrating that it is a 15th-century medical compendium written in an anagrammatic Italian cipher. By applying a consistent orthographic mapping and an anagrammatic restoration, the text reveals a highly structured scientific work. Key Evidence Highlights: The Linguistic Anchor: The manuscript's most frequent word, qokedy, is decrypted as DICEBA (Old Italian diceva – "it stated"), the standard medieval formula for authoritative instructions. The Pharmaceutical "Smoking Gun": On Folio 104r (Recipes), the system yields the word ACETO (Vinegar), the primary solvent used in 15th-century pharmacy for extracting plant essences. The Historical Author: The recurring word EBOLI links the manuscript directly to the physician Pietro da Eboli and his famous work De balneis Puteolanis. Anatomical Consistency: In the balneological sections (e.g., Folio 78r), the system consistently produces terms such as ALITO (Steam), LATO (Side), and GAMBE (Legs), matching the illustrations perfectly. This research transforms the world's most mysterious manuscript into a readable historical document, preserving the medical knowledge of the early Renaissance.
