I’ve chosen these 3 spreads, which have handwritten annotations on page margin.
I found really interesting that the reader and writer, who is probably not Martino Bassi, does not share everything what the author had written, but interrogates himself and what is written. He does not absorb the author opinion but tries to understand and develop it. On page 20 his interrogation is evident, given that his annotation on the right margin of the page is an explicit question. He also underlines what he notices, and probably share; see “notisi ciò” also on page 20. On page 46 he writes “legitima scusa”, as if he really does not share the author point of view.
