Do Herbal A and Herbal B correspond to differences in imagery?

[RenegadeHealer]

A very interesting project. Though my experience with trying to rearrange Q13 is that the number of possibilities will soon make your head spin. Making your own toy bifolios does help a lot, but then still...

Do you have any idea to get you started? Like what might/should be the first page?

Coming from one of the first people I've seen actually make some coherent sense of Q13 (Linda S and Wladimir D being the only other two that come to mind), your humility is commendable, Koen. 

What got me started was the observation that the highly interesting You are not allowed to view links. Register or Login to view. and You are not allowed to view links. Register or Login to view. occupy the left and right halves, respectively, of one bifolio. And on the reverse of this sheet of parchment is two ordinary Herbal B images. This got me thinking of one of two possibilities:

1. f57v and You are not allowed to view links. Register or Login to view. comprised the centerfold of a quire, and were meant to be viewed together. A diagram and a table, respectively, with related information.
   
2. This sheet was originally turned over, with You are not allowed to view links. Register or Login to view. comprising the front cover to a quire, and You are not allowed to view links. Register or Login to view. the back cover, with a sequence of (probably 3) entirely Herbal B bifolios in between. This would give a total of 14 plant images in this little book (or 12 if one of the bifolios was the f58~f65 one, which is tantalizing but problematic), with You are not allowed to view links. Register or Login to view. as the first and You are not allowed to view links. Register or Login to view. as the last. My question to myself is, is there a way that three Herbal B bifolios could be turned and stacked inside f57~f66, such that a logical succession of plant images would reveal itself to someone turning the pages?
   

I intuitively feel like my second option, above, makes more sense. With a cover on this book, this would make You are not allowed to view links. Register or Login to view. (our famous "der muss del" page) likely a table of contents, and the noctrolabe-like rotunda of You are not allowed to view links. Register or Login to view. a diagram on the last page, opposite the back cover.

Let's see how far this takes me. I'm fully expecting to come out of it only more mystified than ever, but it sure is fun!
