'P' is the key

[Loose_Spell_9313]

At some point in this thread, I have missed what the merits are of having a dispute on what precisely 'vellum' refers to, and I'm not putting myself through reading it again.  Surely the key point is that there is a sheet - let's not mention the v word for argument's sake - that measures 29 x 41 cm, and on that sheet there is a drawing of a map that measures 22 x 19 cm?   We can all agree on that, right?

That is my opinion, yes. They are stating that the whole thing (the material) is 22x19cm, which doesn't make sense. 

It only matters in that we are matching the specific stains on one document and another, so the true scale would matter.

It doesn't actually matter because it doesn't closely match either way (i tried every way possible).

No, I see where the difference in interpretation is now. 

My interpretation

Sheet=29cm/41cm black background its on
Vellum= the entirety of the vellum represented is 22cm/19cm

Your interpretation

Sheet=29cm/41cm entire vellum piece
Map= 22cm/19 cm

If you can point to a point of reference where this is clarified, even a series of historical precedent, that would be great. I don't know how one would classify what makes part of the map vs what doesn't in your version though- because without knowing the contents, how could anyone? If you don't have an answer, that's fine- I don't either. I think the only person I would trust to clarify at that point is someone who has handled or has access to the document. 

and to be unbiased, I acknowledge the the 22x19 on just the velum has some proportion issues as far as height-width by that logic- hence my confusion. To me it doesn't make sense why they would differentiate between vellum and sheet. It kinda makes it seem like a materials separation- instead of something like Vellum 29cm/41cm; map 22cm/19cm).
