The Voynich Manuscript
A 15th-century illustrated codex written in an unknown script that has resisted every cryptanalytic attempt for over 600 years.
Overview
The Voynich manuscript is a 240-page illustrated codex hand-written in an unknown script referred to as Voynichese. The vellum has been carbon-dated to the early 15th century (1404–1438). The text uses approximately 25–30 distinct characters; it features botanical, astronomical, biological, cosmological, and pharmaceutical illustrations. Every serious cryptanalytic attempt — including by U.S. and British WWII codebreakers — has failed to produce a verified translation.

Theories & Disputes
Cipher of a natural language (Latin, Hebrew, Turkic) — proposed by Stephen Bax, Greg Kondrak.
Constructed language (a priori) — proposed by William Friedman, NSA's Mary D'Imperio.
Elaborate 15th-century hoax — proposed by Gordon Rugg (2004).
Glossolalia / nonsense — argued statistically improbable due to consistent character distributions.
