I think there's a lot we can say about figurative language n scripture,
but I'm less certain there's much to say about it within a study of hermeneutics.
I guess we can say figurative language EXISTS, and it exists in SEVERAL DIFFERENT FORMS, and we can discuss HOW TO RECOGNIZE IT.
Beyond those few issues I think we're moving beyond principles of interpretation, and moving into the practice of interpretation... so not hermeneutics.

Oxford dictionary definition of hermenutics:
- the branch of knowledge that deals with interpretation, especially of the Bible or literary texts.
