I hypothesize that these illustrations and the accompanying text serve as a model—a representation of something else. I say this because the illustrations contain many elements that appear to be "simulations" or "models" of other things—such as processes, procedures, methodologies, or structures.

Well, nobody has drawn anything remotely conclusive from interpreting the illustrations literally, so you've got nothing to lose
