Horary Astrology Re-examined is a detailed and highly informative book, demonstrating clearly and unambiguously that traditional methods are applicable to all astrology. There is no division between different 'branches'. Barbara Dunn examines the methods by which astrologers of the past evaluated planetary strengths in order to make a judgement on a Question, Nativity, Election or any other type of chart. These evaluations provide a platform for judgement today, in just the same way as they did over a thousand years ago. For all charts, the process of evaluation is broadly the same, what Coley calls the "short comprehensive and approved rules of Art". The focus of this work is Questions and the aim practical rather than philosophical. Horary Astrology Re-examined is a comprehensive reference work, as well as a casebook, giving judgement on over fifty Questions. Ptolemy, Al Biruni, Masha'allah, Abu Ma'shar, Abu 'Ali Al Khayyat, Bonatti, Dariot and William Lilly are just some of the authors referred to. Where there are doubts arising through a poor translation, an unsympathetic translator or other factors, Ms Dunn provides clarification. Instead of seeking to change or modify the tools and techniques handed down by our ancestors, or denying that astrology is about prediction, Horary Astrology Re-examined offers confirmation that astrologers need to "come to grips with their history, complex as it is.. like an isolated ethnic group, they need the courage of their identity in a hostile world."[Kitson]
