There is a clear distinction between text and illustration in the book. 
Each chapter begins with two pages of text, the first is intended to thank the patron funding the author's work, the other is addressed to the reader. This page is the only exhaustive explanation of the contents of the 23 drawing plates following the introduction. 
The following sections, ground plan and frontal views are therefore only accompanied by a sort of legend, which is strictly necessary to ensure that the illustrations are clearly understood. 
The clear distinction between text and image echoes the one found in Diderot and D'Alembert's Encyclopedia published in 1756, which was to serve as a reference on the subject at that time. 
As the Enlightenment aimed to make knowledge accessible to a larger part of the population, the author wrote for an educated public but not necessarily for an elite. 
It is interesting to note that the typography used by Faesch is not recognized by the OCR. The Deepl Translation software, on the other hand, seems to have no trouble rendering a coherent whole to a 17th century German text despite some inconsistencies.
