Resolving whether 86v is a map or not

[Mark Knowles]

So I would think we need to come up with some names of experts on the following:

Medieval cosmological drawings

Medieval drawings relating to the 4 elements

Medieval architectural plans

I don't know of names, off the top of my head, for experts in these areas, but maybe others do. I find that if an expert isn't quite the right person they will have happy to refer you to someone else who they think may be better suited to answer that question.
