The Voynich manuscript is a handwritten book thought to have been written in the early 15th century and comprising about 240 vellum pages, most with illustrations. The author, script, and language remain unknown: for these reasons it has been described as “the world’s most mysterious manuscript”.
Generally presumed to be some kind of ciphertext, the Voynich manuscript has been studied by many professional and amateur cryptographers, including American andBritish codebreakers from both World War I and World War II. Yet it has defied all decipherment attempts, becoming a historical cryptology cause célèbre. The mystery surrounding it has excited the popular imagination, making the manuscript a subject of both fanciful theories and novels: numerous possible authors have been suggested for it.
The “age” of this book is now known: between 1404 to 1438: more.
