Jim Lewis (born James Lewis Slayden; June 5, 1941 in Yonkers, New York) was an American astrologer, writer and entrepreneur. He is best known for pioneering the technique of astrocartography, a form of locational astrology.


Locational astrology[1] is an old concept, but Lewis expanded a little-known field, using detailed maps and modern software. In 1979, Lewis published his first edition of his annual Sourcebook of Mundane Maps.[2] His theories were subsequently developed by other authors.[3]

Lewis eventually patented his system[4] and trademarked the term 'Astro*Carto*Graphy® (A*C*G)'. This registration is still maintained by the Astro*Carto*Graphy Living Trust.[5] A non-profit division of the Astro*Carto*Graphy Trust—Continuum: the Jim Slayden Lewis Foundation—lists over 20 book titles including those by Lewis that are either devoted to Astro*Carto*Graphy or where the technique features extensively.[6]

For his original work in developing and promoting the technique of Astrocartography, Lewis received the Marc Edmund Jones award in 1978[7] and the "Regulus Award for Discovery, Innovation, and Research" at the United Astrology Congress in Washington, DC 1992.[8]

Lecturer and teacher[edit]

Lewis regularly conducted seminars in which he trained students in Astro*Carto*Graphy techniques. He later went on to administer a certification exam. Candidates who passed his stringent qualifications were given a certificate as a professional Astro*Carto*Grapher. As of February 2008, Continuum listed 88 certified practitioners around the world.[9]

Lewis lectured throughout the world. However, in his travels he was not immune to the negative potential of A*C*G's ‘planetary power lines’. In the mid 1980s he was struck by a vehicle while crossing Military Road in Sydney, Australia, which is on his Mars Ascending line.[10]


Lewis lived in San Francisco for most of his life. At age 53, he died from an aggressive brain cancer; his ashes were spread at Big Sur.[11]
