Jim Lewis, born James Lewis Slayden, was an influential figure in the world of astrology, particularly known for his pioneering work in astrocartography. Born on June 5, 1941, in Yonkers, New York, Lewis spent
his early years in a commune in Big Sur, California, where he engaged in activities like deer hunting. His journey into astrology led him to develop techniques that would revolutionize the field, leaving a lasting legacy.
Early Life and Career Beginnings
Jim Lewis's early life was marked by a unique blend of experiences that shaped his future endeavors. Growing up in Yonkers, New York, he later moved to Big Sur, California, where he lived in a commune. This period of his life was characterized by a connection to nature and a sense of community, which may have influenced his later work in astrology.
Lewis's career in astrology began in earnest in the 1970s. He was instrumental in expanding the field of locational astrology, an ancient concept dating back to late antiquity. His innovative approach involved creating detailed hand-drawn maps with transparent overlays that showed angularity lines. These maps were accompanied by interpretations in a "cookbook" style, making astrology more accessible to a wider audience.
Contributions to Astrocartography
Jim Lewis's most significant contribution to astrology was the development of Astro*Carto*Graphy, a technique that mapped celestial positions to geographical locations. This method allowed individuals to understand how different locations could influence their lives based on astrological factors. Lewis began sending out hand-drawn mail-order maps to clients in 1976, branding his techniques under the trademark Astro*Carto*Graphy.
The foundation of Astro*Carto*Graphy was built on the work of previous locational astrologers, including British astrologer Sepharial and Canadian astrologer Edward Johndro. Lewis's techniques were further refined by contemporary astrologers, leading to the creation of more sophisticated tools. By 1966, the first computer-generated Astro Locality Map was published, setting the stage for future innovations.
Legacy and Impact
Jim Lewis's impact on astrology was profound, earning him recognition and awards for his contributions. In 1978, he received the Marc Edmund Jones Award, and in 1992, he was honored with the Regulus Award for Discovery, Innovation, and Research at the United Astrology Congress in Washington, D.C.
Lewis's legacy continues through the Astro*Carto*Graphy Trust, which he established in his will. The Trust offers certification for astrologers and provides access to transcripts of Lewis's lectures. His work has influenced countless astrologers and continues to be a vital part of the field today.
Jim Lewis passed away on February 21, 1995, in San Francisco, leaving behind a rich legacy that continues to inspire and guide astrologers worldwide.
