Bifolio as a functional unit?

[dashstofsk]

I would like to present the results of my own investigation which gives further evidence for the hypothesis that the manuscript was written sheet-by-sheet at not in book page order.

By sheet-by-sheet I mean that the writer wrote one sheet at a time, first both halves of one side then turned the sheet over and wrote both halves of the other side.

I found this to be the case for both quire 13 and quire 20. The evidence for this is given in the attached PDF output. For each of these quires it shows values of page-by-page correlations, with the highest page pair correlations listed first. You will see that page pairs that are on opposite sides of a sheet ( SIDE ) and page pairs back-to-back on the same leaf ( LEAF ) tend to appear towards the front.

In particular note the pair You are not allowed to view links. Register or Login to view. / f81r, first in the list for quire 13. Not only do their text have the best correlation but it feels significant also that the drawings on those pages look similar ( green water in a bath tub that has raised sides ). It suggests that these pages were done in one sitting.

Pair 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. ( LEAF ) are also well correlated, and You are not allowed to view links. Register or Login to view. continues with the balloon shaped blue pools started on f84r. Also on that same sheet, 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. ( SIDE, and in the first quarter ) both have some fancy decoration above the bathing pools, and You are not allowed to view links. Register or Login to view. also has a blue balloon pool. Possibly all done in the same sitting also.

If you want to know how the correlations were generated then it was like this:

For each page within a quire I calculated the frequencies for a range of parameters ( top words, top prefixes, top suffices, top character pairs, frequencies of gallow words, frequencies of words that appear once in the quire, frequencies of long words, frequencies of words of two characters, frequencies of words that contain  s,d,e,a,n,r  ). Then for each page pair I summed the absolute values of the differences between all their frequencies to get a score. Better correlated pages would get a lower score.

To illustrate with an example here are the frequencies of word  ol in quire 13. 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. are both high in this word.
