Why and how the text could be Bavarian

[Stefan Wirtz_2]

Well, and what if the tar pit is exactly what nobody wants to see?

You should really care for the tar pit, as you reached it‘s rim already: until now, all theories got stuck in it. There is a whole list of them in a section of this forum, and all other tries failed also.

Most people here do not cross an imaginery line from Vienna to Stockholm and stay with their ideas within the area west of that line;  
but here are no „unknown“ languages which may fit to VMS texts, all known languages do not work out with it, and the basic Latin alphabet was completely developed and dominant in Western Europe since ancient times — as well as grammar and structure of Latin influenced all Romance and western languages.
For Greek and it‘s area: same. 
VMS will not work with anything out of the Greek-Latin complex or even with any (West)Germanic/Scandinavian languages.

The trick is to find a european language that complies with the strange structure of VMS text, not to force some favourite language (and theory) with twists and tricks and wildcard-interpretations into an „understanding and solution“ of Voynichese.
Yet, I just saw much things that may be called „barking up the wrong tree“ (very German proverb, imperfectly translated to english. Might show im a nutshell where the problems are).
