Enea Arnaldi – “Delle Basiliche Antiche”
I found this plan of some sort of basilica very interesting, in particular how orderly and proportional all the architectural elements line up.
Furthermore, this page also caught my attention as different proportions are listed for various elements.
The book overall was about the size of an A4 sheet, wasn’t all to heavy, but the pages were very stiff. The pop-up pages for the various plans really intrigued me.
