The VMS is an illustrated manuscript handwritten in an unknown writing system

[Anton]

From the beginning, the VMBOK initiative at once went into some quite specific statements about imagery, text et cetera. I would like to pay attention to some generic introductory statements which are also needed. So one of these is (partly adopted from Wikipedia):

Statement [UPD Nov 2, 2016]

• The Voynich Manuscript is a manuscript handwritten in an unknown writing system and containing numerous images.
  

Explanation

As opposed to Wikipedia, I chose "manuscript" vs "codex", because IMO there's not enough evidence that it was really meant to be a codex.

"Handwritten" may seem excessive, since the word "manuscript" implies this, but nowadays the word "manuscript" often designates something not literally handwritten (e.g. "to submit a manuscript to a journal"). So "handwritten" would not harm.
