For a number of years, I've tried very hard to figure out where Kircher's engraver found the sources for these drawings. Engravers usually work from previous references (or a synthesis of previous references together with notes and instructions from the author).
Unfortunately, it has been difficult to trace these sources backwards, so after devoting countless hours to it, I don't have much info.
