In the Rider-Waite deck, this is one of the busiest cards. In addition to the Wheel, it includes Hebrew and alchemical characters, clouds, four angelic figures, a sphinx, and a devil. Since one of my goals has been to remove all recognizable symbols, I originally chose only to use the Wheel -- represented as a very simple wind rose -- and the sphinx and angel. For this version, I have retained only the wind rose, although I have added some ornamentation to it. You can see the original version here.
