The Voynich manuscript is an illustrated codex hand-written in an unknown writing system. The vellum in the book pages has been carbon-dated to the early 15th century (1404–1438), and may have been composed in Northern Italy during the Italian Renaissance.The manuscript is named after Wilfrid Voynich, a Polish book dealer who purchased it in 1912.
The pages of the codex are vellum. Some of the pages are missing, but about 240 remain. The text is written from left to right, and most of the pages have illustrations or diagrams.
The Voynich manuscript has been studied by many professional and amateur cryptographers, including American and British code breakers from both World War I and World War II.No one has yet succeeded in deciphering the text, and it has become a famous case in the history of cryptography.
The Voynich manuscript was donated by Hans P. Kraus to Yale University’s Beinecke Rare Book and Manuscript Library in 1969, where it is cataloged under call number MS 408.
