15thc perception on swallowtail merlons?

[MarcoP]

Unfortunately, he did not translate the labels. Maybe someone here can help?

Those two pages are amazing, thank you very much for sharing them, Pierre!

I think I can help, but I am not sure what you are asking. Finding the modern names of the listed places, or transcribing parts of the text (labels) that are missing?

EDIT: the labels in f.75v:
Monsferratus
Rocha Gasseni 
Pars superior Montis ferrati

I am not sure about the town at the center, it looks like "Capsa ville", but I don't know what that might be.

Left margin: Planicies Pedemontium

EDIT2: I see that "Casale Monferrato" is "Casà" in the local dialect. So Capsa could be that.
