It is remarkable how long books survive, but still manage to be forgotten and not cared about. Well actually some books never really mattered, written only for personal gains, like selling a geometrical tool. It should not be a surprise that this book was forgotten, because it is just such a book. But yet it still survives for it was published centuries ago and once things are out there they don’t just vanish.
Maybe if I could read Italian I would appreciate it more, but just by reading summaries I doubt I actualy would. This also made it difficult to do the conversations.
