The Sabian Symbols were images visualized by a psychic in 1925, randomly (or supernaturally) assigned to the 360 degrees of the Zodiac. They are peculiarly evocative, and the insightful astrologer Dane Rudhyar does a masterful job of analyzing the 360 symbols as a coherent sequence. I've found the symbols to add a new, more individual layer of meaning to an astrological chart. People who are drawn to Tarot would probably relate strongly. It would be interesting for someone to design a Tarot-like deck of cards based on the Sabian Symbols--though it might be hard to shuffle 360 cards!
