Throughout the book Guarini cites a lot of numbers and single letters, since i don’t understand Italian I couldn’t decrypt the numbers or the letters. There are no pictures in this book except these symbols appear three times in the book. It looks like there’s a crown in the middle surrounded by natural looking structures. It might be a royal emblem because of the crown. The pictures can always be found at the end of a chapter.The first letter of every chapter or sometimes a new segment is big inside a quadratic picture, in the background of the letter seems to be a nature scenery or some kind of building outside.
