Alphabetically arranged entries cover the history of astrology from ancient Mesopotamia to the 21st century. In addition to surveying the Western tradition, the book explores Islamic, Indian, East Asian, and Mesoamerican astrology. The field of astrology is growing rapidly, as historians recognize its centrality to the intellectual life of the past and sociologists and anthropologists treat its importance in a number of modern cultures. Despite the historical and cultural significance of the subject, most reference works on astrology focus on instructional techniques and are written by astrologers with little or no interest in the history of the topic. This book instead offers an objective treatment of astrology across world history from ancient Mesopotamia to the present. The book provides alphabetically arranged entries by expert contributors writing on such topics as horoscopes, court astrologers, Renaissance astrology, and comets. While it considers the Western tradition, it also treats Islamic, Indian, East Asian, and Mesoamerican astrology. In doing so, it explores the role of astrology in shaping science, literature, religion, art, and other defining cultural traditions. Sidebars offer excerpts from various historical texts, while entries provide suggestions for further reading.

In 1919, a Canadian teenager with a sixth-grade education arrived by train to the wilds of Los Angeles. Within a decade he had transformed himself into a world-renowned luminary and occult scholar. His name was Manly Palmer Hall, author of the landmark encyclopedia The Secret Teachings of All Ages and the 20th century's most prolific writer and speaker on ancient philosophies, mysticism, and magic. Hall revealed to thousands how universal wisdom could be found in the myths and symbols of the ancient Western mystery teachings. He amassed the largest occult library west of the Mississippi and founded The Philosophical Research Society in 1934 for the purpose of providing seekers rare access to the world's wisdom literature. He became a confidante and friend to celebrities and politicians. In 1990, he died - some say he was killed - in what remains an open-ended Hollywood murder mystery. This dramatic story of Hall's life and death provides a panorama of twentieth century mysticism and an insider's view into a subculture that continues to have a profound influence on movies, television, music, books, art, and thought.
