What if the images are entirely like the text, various scenarios.

1. The text could be an illiterate culture/language's first attempt at writing in its own writing system. In this case, and remember that for this exercise we imagine that the images belong to the same sphere as the text, what would we expect? Every culture has an artistic component, this was already true in the Stone Age. So we would expect part of that artistic tradition to shine through in the imagery. If we take into account the stylistic properties of Voynichese, chances are this culture is not European - probably Asian? So given the premise of this thread, the imagery should have Asian influences. But it doesn't, at least not in an in-your-face way. So if we have Asian text, with non-Asian images, what happened?
   I probably missed a few?

Hi, Koen:
I'd like to propose a variation on 1  -- let's say 1(a) -- that I personally find more likely.  

It wouldn't shock me if the Voynich is an expression of a culture (both text and imagery) not of an illiterate group but of a group holding a particular belief system.  This belief system is such that it necessitates the encoding of the text, either because of fear of prosecution or a general desire to keep out those "not deserving" of the knowledge (like Latin knowledge had been doing at the time).  

I know this has been suggested many times, but it seems that there were many "splinter" groups at the time of the carbon dating and I would not be surprised if the VM could be the outward expression of more mainline European scientific beliefs (such as they were) but seen "fractured" through their group's particular belief system.  Thus, this would suggest that if the tilting of the manuscript's imagery away from things more commonly seen at the time can be described concretely, this collection of "shifts" could be used to describe a belief system held by the authors and in that way it just might be possible to find a group holding with these beliefs.

I realize this is highly subjective and abstract and certainly not original -- but it was the first slightly different approach to your thought experiment that came to mind.  Thanks for sharing it!
