Bifolia created using previous as reference

[npcompl33t]

Hello

Using the spatial analysis toolkit i shared recently, I believe I have found very convincing proof that previous bifolio were used in the creation of a new bifolio. You are not allowed to view links. Register or Login to view.

Using my recovered spatial coordinates, i can gather two measurements: margin offset, and text angle. Viewing the bifolia in the correct sequences shows that these values carry over between most bifolia, while slowly drifting over time, and serve as a completely text-independent marker of production sequence. 


Below we will see how:

• Layfield and Davis singulion hypothesis is correct
  
• Previous bifolio were use to set the margins and text angle of the current bifolio.
  
• Broad Golf Sequencing Holds
  
• This can help to resolve uncertain orderings.

Margin offset can be measured in the following way:

   

Plotting these values by page-within-bifolia immediately reveals trends that are related to bifolio face:

   


This can then be combined with the angle of the text. This is essentially how slanted the text is on a page.  For example, You are not allowed to view links.

To create a singulion, it would be justified in the opposite direction from the other 3 pages. 

   

Bifolio were written in the same singulion order proposed by davis. The first page of this singulion is typically preserves the least offset. The final page frequently accumulates an offset and slant completely independent of the other 3 pages, that will also carry over between pages.


But it can be hard to picture how these graphs may relate to the actual pages.

When arranged in my proposed golf ordeering, these horizontal offsets and offset angles form clear sequences. I am not claiming this is the perfect order. But it is clear that it is close, and many pairs likely do capture true production sequence. We can see that the angles and offsets from previous bifolio are frequently copied to the next.

Here is the beginning of the manuscript. This shows the pages in singulion order. Note the extreme angle of the right-most page, which carries over between the bifolia seperately from the offsets of the other 3 pages.

   

Here is a slightly different ordering

   


The stars section appears to have had the sheets at least partially obscured by the new one. You can see the margins mostly align if you arrange them at covering around 50% of the previous. After about 50%, the margins diverge, sometimes sharply.

   

Again, I am not claiming the exact sequence is correct, and encourage others to try swapping the ordering. It is clear that in many cases, previous bifolia were used as a layout reference for the one being produced, as margin offset, and text angle get reproduced on the newer bifolio.

The next step will be to analyze this data more thoroughly to determine the most likely possible parings.
