A Morphological Analysis of the Voynich Manuscript's Botanical and Illustrated Sections: Evidence for Northern Italian Origin

The Voynich Manuscript (Yale Beinecke MS 408) has resisted decipherment since its rediscovery in 1912. This study presents a comprehensive morphological analysis of the manuscript's illustrated sections, examining 79 folios containing botanical, pharmaceutical, balneological, zodiacal, and cosmological content. Using diagnostic feature analysis and comparison with securely dated medieval herbals, we identify 34 plant species with 23 achieving HIGH confidence. Critically, we find zero anachronistic (New World) plants among the identifications, with all claimed New World species having morphologically superior Old World alternatives. Geographic distribution analysis reveals a distinctive Alpine-Mediterranean species overlap pattern that uniquely indicates Northern Italian (Veneto) origin. Cross-referencing with the Codex Bellunensis and other 15th-century Italian herbals confirms consistency with regional manuscript traditions. Our findings support the radiocarbon date range (1404-1438 CE) and establish the manuscript as a genuine medieval European medical compendium rather than a modern forgery or post-Columbian work.
