Hello to you!
I'm truly delighted that you've posed this question. I've recently dedicated time to studying this particularly intriguing manuscript and would love to share some of my observations and theories.
Upon examining the manuscript, I noticed that many of the letters have this rounded shape and clarity that are typical of humanistic writing. Moreover, the spacing between letters and words is consistent, which is also a characteristic of humanistic script.
It's challenging to pinpoint a specific humanistic script as there have been several variants. However, the overall fluidity and shape of the letters are reminiscent of certain humanistic writings from the 15th century in Italy.
Gothic writing, for instance, is usually more angular and tight, which contrasts strongly with the open and rounded letters of humanistic. Carolingian script, although it also has rounded letters, is older and its letter forms differ from those of humanistic. The main reason I've leaned towards humanistic is the combination of clarity, rounded shapes, and consistent spacing, all of which are typical characteristics of this script.
Where it gets truly interesting is that some letters seem to be linked, suggesting a cursive influence. This blend of humanistic traits with cursive elements makes the writing genuinely unique.
I'd love to hear your thoughts on this and if you have similar examples or ideas to share!
