In this book, Charles Carter (1887-1968) shows how the Zodiac of twelve constellations describes an ideal world. In other words, how the soul - the ideal - reveals itself in astrological terms. In the process, Carter invents a new form of rulerships, based on the traditional exaltations, which includes the outer planets. Carter also teases us with his unpublished system of numerology, which was based on 12, rather than the usual 10. As astrology is based around the numbers 2, 3, 4 and 12 (not 5 or 10), a base-12 number system is of immediate interest. Realizing his subject was abstract and unlikely to appeal to all, Carter also includes innovative ideas on directing, and on transits. The result is a book that fascinates on many levels. Charles E.O. Carter, one of the leading astrologers of the 20th century, was President of the Astrological Lodge at the Theosophical Society from 1920 to 1952. He was first Principal of the Faculty of Astrological Studies, which he helped found in 1948. He edited The Astrologer's Quarterly from 1926 until 1959. The Zodiac and the Soul was first published in 1928, with revisions in 1947, 1960, and 1968, the year of his death.
