For the last task, I wanted to look for books that are related to my book in terms of topic, but also in terms of scope and physics. I tried it with different search terms, until I became aware of the following two books:
Comment on _25
The first book I found is Architectura civilis by Joseph Furttenbach. I found it through the search civilis and see very many similarities. Even just the title is very similar and it is immediately clear that it is about civil architecture as well. In addition, the book is also written in German and has, among other things, many drawings. One difference is that Joseph Fruttenbach lived in the 16th and 17th centuries and Johann Jacob Schübler in the 17th and 18th centuries. They missed each other by 20 years. So what is quite possible and I actually assume that Johann Jacob Schübler knew the work of Joseph Fruttenbach and also used it as inspiration.
The second book, which I can also link well to my book is, “Instituzione pratica dell’ architettura civile per la decorazione de’ pubblici, e privati edifice” by Paolo Federico Bianchi. As can be seen from the title, this book is also about civil architecture. Paola Federico was a Milanese architect who designed, among other things, the “Klosterplatz” in Einsiedeln. The book also seems physically similar to my book, “Synopsis architecturae civilis eclecticae” by Johann Jacob Schübler. It has about the same thickness and number of pages and also contains a great many drawings. It was exciting to see that in another language area similar things were written and drawn about architecture. Also this book was certainly used to teach and spread the knowledge about architecture and also written with this aim by the author.
