Since we're on the topic of esoteric occult stuff. Some cycle work Gann students might be interested in.
If you are talking about the squares (levels) - one within another, and the diagonals when looking from the top, that is NOT a spiral to me. In fact, I have only been able to find two more modern examples of number spiral (e.g. Ulam Spiral) which do not seem to have any historical link to Gann Square of Nine.
