A 240-page medieval codex filled with impossible plants, bathing women in green pools, and swirling astronomical charts — all written in an alphabet no one on Earth can read. Alan Turing failed. The FBI failed. Six hundred years of the world's best codebreakers have all walked away empty-handed.
A quick, vivid tour through the strangest object in Yale's rare-book vault: the plants that match nothing in botany and the script that matches no known tongue.
The definitive rabbit-hole hub: carbon-dated to 1404–1438, sold by an emperor, gifted to a Jesuit, and still unread. Start here for the full provenance and every failed theory.
A feature-length documentary tracing the book from Rudolf II's court to the modern cryptographers who've lost years of their lives trying to crack it.

One of a long parade of 'I solved it' claims — this one arguing the language is based on Hebrew. Read why the experts keep saying: not so fast.
