The Voynich Manuscript
An early-15th-century illustrated codex written in an unknown script that no one has convincingly deciphered — what it contains, what has been ruled out, and why it resists.

The Voynich Manuscript is a 240-page illustrated book, carbon-dated to the early 15th century (1404–1438, vellum), written in an unknown script that has resisted every decipherment attempt for over a century. It is named for Wilfrid Voynich, the book dealer who acquired it in 1912; its author, purpose, and meaning remain unknown. It is the most famous unsolved text problem in linguistics.
What is known
The text flows left to right in an unknown script of 20–30 distinct glyphs, organized into "words" with statistical properties that resemble natural language: letter frequencies follow Zipf-like curves, words repeat with predictable structure, and entropy measures are lower than random text. The illustrations divide the manuscript into sections — botanical drawings of unidentifiable plants, astronomical and zodiacal diagrams, balneological (bathing) figures, pharmaceutical jars, and pages of dense short text.
What has been tried
Proposed solutions have included known languages (Latin, Hebrew, Nahuatl, various Romance languages), constructed encodings, glossolalia, and elaborate hoaxes. Statistical work shows the text obeys Zipf's law and other natural-language regularities, which argues against pure gibberish, but no proposed decipherment has survived expert scrutiny: the "solutions" announced periodically do not generalize beyond their authors' selected pages. The one solid result came from radiocarbon dating (2011) and multivariate analysis of the pigments and ink, which established the vellum's origin in early 15th-century Europe.
Current assessment
The honest state of knowledge is: a genuine medieval or early-Renaissance artifact, written in a script that encodes something — a language, a cipher, a constructed system, or elaborate glossolalia — that satisfies the statistics of real text. Claims of decryption appear regularly and fail review.
