The VOYNICH Manuscript Explained in 70 Minutes | History for Sleep

Inside a secure vault at Yale University sits a handwritten book that no living person can read: the Voynich manuscript. Its vellum dates to between 1404 and 1438, yet who wrote it, where it was made, and whether its pages hold a language, a cipher or a hoax remains unsettled. Across eleven chapters it covers the physical evidence for the manuscript's age, including the 2009 sampling and the radiocarbon range of 1404 to 1438, and the trail of owners from Prague and Rome to Wilfrid Voynich and Yale. It follows the claims that Roger Bacon wrote it, the codebreakers from William Friedman to John Tiltman who studied it, and the statistical debate, in which Marcelo Montemurro and Damian Zanette argue the text behaves like a real language while Gordon Rugg and others argue a hoax could produce the same patterns. It then sets the claimed decipherments of Stephen Bax and Gerard Cheshire against what specialists say a solution would need, and ends on what is known and what is not.
