title_body: Is the Voynich manuscript written in a natural or constructed language? The Voynich manuscript is dated to the early 15th century.
  
  
  
  
    It is a medieval handwritten book of almost 250 pages, and even today the text cannot be understood. It has become quite famous, and it is recognised as one of the main unsolved problems in the history of cryptography.
  
  
  Can we tell whether it is written in a natural or constructed language?
upvoted_answer: We don’t know. It is written in an unknown script, by an unknown author. We don’t even know whether it is even in any language at all, or just random scribbles. Any attempts to connect it to a known language (such as Latin) have failed thus far.
