I have read about this manuscript in William Poundstone's The Labyrinths of Reason. Researchers showed that the script was not meaningless scribblings; i.e. it had an entropy content similar to Polynesian languages (weird, huh?). His best guess was that it was an enciphered version of an artificial language (a la Esperanto) made up by the unknown author, and for that reason we will probably never crack it. I bet if we did we would be disappointed at its content.

Also, languages were still being spoken in the 15th century that have since died out. While this could well be an artificial language, it could also, at least theoretically, be from a small group of people that were later assimilated into another, neighboring culture.

Every century has its "medved".

Allow me to translate:

Once we finally figure this out we will probably see it is nothing more than chemistry or music theory.
