This spread occurred outsanding to me because of its atypical layout that sets it apart from the rest of the book. On most sheets you can see different illustrations of external facades, entrances or windows, that where built in Florence around that time. The exact drawings always show the facades as one, but this spread divides the different elements very beautifully into multiple pieces to explain what elements are needed to build the exterior of a building.
These two pages are very interesting because they are filled with words. In comparison, most pages contain mainly precise illustrations, but this one is an exception and must be at a part of a book which focuses more on text than on drawings.
The last spread shows nicely how most parts of the book look like. On the left, an empty page that’s very thin, because of which you can guess what’s on the page behind it. And on the right, a very precise drawing of the exterior structures of the building.
