Do you know the structural patterns one might find in ancient writing?

Question

I am studying for a test in religion, but I am having trouble to understand these structural patterns.

Kiastic

Concentric

Conclusion
I know this consitst of letters like
A-
B-
C -

Answer 1

Kiastic? do you mean with an L, klastic=broken like A? I am not sure either but I was curious about the word and I could not find it.
Conclusion means closing together so that should be like B, Concentric means with the same center so I would expect it to be like O or C.
I am just guessing though.
Does this make sense in your textbook?

Edit:" The answer above makes much more sense;

Conclusion then would be summing or restating the main points at the end of the piece and concentric would be drawing different points of view to a central point or theme. I think.

You are not asking about the letter forms, but about the composing of the passages.

Answer 2

I don't know, but I'm going to watch your question because I'd love to see the answer! I love linguistics.

Since this question is oriented more on writing patterns than religion, I think you're more likely to get informed responses from Society and Culture ----> Languages.

Answer 3

I know of Chiasmus which as a form of religious writing that goes

a
b
c
b
a

Where c, being in the middle, is the most important concept. It's commonly used in scriptural versus, chapters, and even whole books.
