Proposed Manuscript Chronology

[MarcoP]

• Proposed: Bio represents a comparatively stable production phase, with its internal differences mostly unrelated to progression.
  
• Alternative: Bio contains a stronger internal progression that the sequence follows.
  

Thank you for the detailed reply and for visually comparing the two different models!

Of course, the fact that the Proposed seriation places f116 very near to the end of the sequence is consistent with both the binding of the MS and the almost-blank page at f116v.

On the other hand, people have suggested a progression in the Bio section, in particular based on illustration subject and layout: Marginal-Pipes (Q13A) vs Central-Pools (Q13B). See for instance:

It would be interesting to see if the Alternative seriation matches the image split between Q13 pages:

Q13a – medical – biological – Galenic

76r/76v – bifolio 2 > medical
80r/80v – bifolio 5 – flipped > medical
77r/77v – bifolio 3 > biological
82r/82v – bifolio 3 > Galenic
79r/79v – bifolio 5 – flipped > Galenic
83r/83v -bifolio 2 > Galenic

Q13b – Balneological

84r/84v – bifolio 1 – flipped > balneological
78r/78v – bifolio 4 > balneological
81r/81v – bifolio 4 > balneological
75r/75v – bifolio 1 – flipped > balneological

There are a couple clues that say Q13b was written after Q13a
