Convoluted secret writing
It appears so from the ancient Greek, looking it up in the dictionary.
If that is what it is, and not a mistaken interpretation. Say something is convoluted or "twisted" as with great strength, by a man who could squeeze a drop of water out of a dry rag. The Gordian Knot comes to mind, also ancient Greek.
