Dissolving the Mystery: The Anatomy of a Codicological Fraud and Cryptographic Fabrication Target-Oriented at Emperor Rudolf II

This paper demonstrates that the “Voynich Manuscript” (Yale University, Beinecke MS 408), long considered anindecipherable medieval mystery, is an organized, extemporaneous pseudo-scientific ledger created in the late 16th toearly 17th century Prague. Its primary purpose was to defraud the Holy Roman Emperor, Rudolf II, of 600 gold coins. Acabal of six court scholars, including the prominent Johannes Marcus Marci, colluded under a clear economic incentive tosplit the 600 gold coins equally (100 gold coins per person). Exploiting Rudolf II’s profound obsession with astrology,alchemy, and the elixir of life, they fabricated a theatrical manuscript based on contemporary scientific rumors andcloaked it via an unrefined “position-based alphanumeric deletion/substitution cipher.” By profiling the perpetrators’psychological tendency to shirk labor, alongside anomalies in penmanship consistency, this study systematicallydismantles the manuscript’s architectural camouflage and restores the underlying plaintext.
