Automated Topic Analysis of the Voynich Manuscript

[quimqu]

What got me confused is that the plots show gradual transition (slanted lines) between topics.  But those slanted lines are an artifact of the plotting routine.  For instance, from You are not allowed to view links. Register or Login to view. to f17v the plot suggests a gradual transition, but the transition is actually abrupt: You are not allowed to view links. Register or Login to view. is 100% "brown",  You are not allowed to view links. Register or Login to view. is 100% "green", then You are not allowed to view links. Register or Login to view. is again 100% "brown".  Right?

That's it.
You are not allowed to view links. Register or Login to view. has topic 2. It skews to the -ol/-or family and -eol/-eey clusters: ol, chol, or, cheol, cheor, sheol, qokol, qokeol, okeol, cheey, sheey. It also shows longer ""vowel""-heavy strings like saiin, qokeey, and compounds like cthey. Overall: lots of -ol/-or endings and ee sequences.
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. have topic 5. It leans hard into the -chy/-ty/-y morphology with "sh/ch/cth" frames: chol, chor, shol, sho, dy, chy, cthy, dain, shor, shy, chey, qotchy, qokchy, otchy, cthol, cthor, qoty, oky. Overall: shorter tokens, many -chy/-ty/-y endings and cth/ch/sh stems.

[*]By the way, I attach a plot of the topics with the current order of folia (so, folia as they are bound):
