The book I was in charge of is named «Inventioni» and consisted of hand drawings of mainly cornices, columns and entrances. Therefore I typed in “cornice”, “column”, “entrance” and “drawing” as search elements into Alice. What I got where extracts of texts of various books around those themes.
Tronzo, St Peters in the Vatican
Information gotten over this book consists of descriptions of pictures/ figures shown in the book. The first description is about a picture drawn of a nave, which had to be made before a particular “muro divisorio”, that was built in 1538, blocked the sight towards it. The next descriptions goes about a crossing and its surroundings (columns, altar, etc.). I suspect this crossing to be inside of some kind of spiritual building. In the following descriptions it becomes clearer what the text is all about. It gathers information about the original Basilica that was built on the cemetery where the tomb of St. Peters is thought to be.
I think the pictures, which the text describes, especially the ones of the excavations in 1939 underneath the present basilica could have similarities with drawings found in “Inventioni”. I think however that the figures showing the nave or this particular crossing would have more of a perspective element to it, which is not what is shown in “Inventioni”.
Serlio, Sebastiano Serlio on Architecture Volume 1
The text is about the representational function of arches. It describes what materials they were once built, how they are built at this particular time and for what events they are built. Then it dives deeper into Arches of the Corinthian order and how they are should be proportioned correctly.
I don’t remember having seen arches in “Inventioni”, but there were a lot drawings of entrances for example in the Corinthian order. As well the aspect of materialization and proportion could explain the forms and structures shown in “Inventioni”.
