On these 3 pages of the book, we see drawings of the old St. Peter Church in Rome. There are a big floor plan and two cut perspectives. Interesting is that the floor plan pages is very big, that you must fold it.
On the next 3 following pages shown, we see different examples of possibly altars and statues of a church. This detailed drawing stands out of the others because the most drawing are buildings plans or facades.
The next pair of pages is interesting because we have a detail drawing of several little paintings. On the first ones, we see several pictures which tells a story of the bible. On the other two drawing, we see Jesus in his childhood on the left side and on the right side as an adult. These two pages are interesting, that the author also made so big importance to that little paintings in the church.
