World Mysteries: The Voynich Manuscript
Theories abound about the origin and nature of the manuscript. Some believe it was meant to be a pharmacopoeia, to address topics in medieval or early modern medicine. Many of the pictures of herbs and plants hint that it many have been some kind of textbook for an alchemist. The fact that many diagrams appear to be of astronomical origin, combined with the unidentifiable biological drawings, has even led some fanciful theorists to propose that the book may have an alien origin.
One thing most theorists agree on is that the book is unlikely to be a hoax, given the amount of time, money and detail that would have been required to make it.
While I may not agree with Prof. Gordon Rugg and his theory, the video below has alot of info:
