The Voynich manuscript is a mysterious, undeciphered illustrated book. It is thought to have been written between 1450 and 1520. The Voynich manuscript has been the object of intense study by many professional and amateur cryptographers, including some top American and British codebreakers of World War II fame (all of whom failed to decrypt a single word).
