Erased lines? - VViews - 29-07-2018

Hi everyone,
looking through the astronomy section lately I was struck by what appear to be traces of erased lines under the main drawing on f68v1:

You can see them peeking through between the stars in the two sections at roughly 12:00 and most prominently at about 4:00.
The lines don't seem to be bleedthrough from the other side, nor could they be explained by transfer from the other foldout pages.
I wonder if they are remnants from a former design idea for the page, or if we might, after all, have to reconsider the palimpsest possibility.

This is quite interesting!

The palimpsest idea is perhaps a little bit too adventurous. With the hundreds of people who have inspected the manuscript, among whom there were certainly several dozens of highly qualified manuscript experts, the chances that the MS is a palimpsest, which somehow escaped attention are vanishingly small.


Ink or paint transfer from other pages is our best bet, and one thing that stands out is that the dark blue paint has been particularly sticky onto other pages.

Now the bifolio comprising folios 67 and 68 has received a lot of attention, since it seems to have been bound incorrectly into the manuscript. This was discussed already more than a decade ago, by one of the Groves (I believe it was John, not Jon), Nick Pelling and others.

This is how it has been bound into the book:

   

However, possibly, it should have been bound through the fold between f67r2 and f67r1.

In the first case (the present one), if one folds the folio in completely, the opposing page would be f69r.
In the second case, it would be f67v2.
(This takes a bit of mental origami and I hope I got it right).

Now let's take a closer look at the smudges between 11 and 12 o'clock:

There's a row of circles, and some vertical lines. I think that these match up quite well with blue paint that may be found on f69r:

This tells us that, when the blue paint was still wet, the bifolio was bound into the MS in the way we see it now.

Second: actually, I have already been reminded before by Alain Touwaide that the bifolios may have simply been stacked after having been written and painted, well before they were actually bound into a codex. We don't know if that was the case, but if it were, the 'mistake' was already made at the earliest stages of the MS creation. This would fit with the observation made by Paula Zyats that the pinholes seen in the fold between f67r1 and f67r2 are simply knife cuts, and have never actually had any thread go through them.

Thank you ReneZ!
I hadn't considered 69r as the source, but they do match up.
There is also one more blue "spoke" from the 69r diagram that transferred around 7:00:

However, I'm not sure I agree with your conclusion that this necessarily means the MS was bound when the blue paint was still wet, or that the transfer occurred during pre-binding stacking.
Wouldn't it be at least equally probable that this means the paint transferred because it was added after the MS was bound into its current binding?

I should have done a bit more research before posting this.
It turns out these lines were already flagged by Nick Pelling waaay back in 2009...
Here's a link to his blogpost on the subject:

Oh well! :-)
