The document discusses how ancient astrologers could have learned about the precession of the equinoxes through observation and symbolic/iconographic thinking rather than just literal observation. It introduces the concept of the "Matrix of Wisdom," a symbolic representation of the soul and psyche that is said to be the foundation for many religious and esoteric traditions. Calculations based on coloring and numbering cells in the Matrix of Wisdom produce values close to half and the full precession of the equinoxes cycle, suggesting this was how ancient astrologers envisioned and calculated the precession.
