On 16.07.2022 at 21:00 BG time will be held a seminar on "Comparison between the texts of Hermes, Anonymous and Ptolemy on the stars, Part I". In this seminar a comparison of the texts on the stars by the key authors of antiquity - Hermes, Anonymous and Ptolemy will be made. This is crucial for recovering the ancients' overall conception of their vision of the stars and their influences. In this first part of the sub-cycle, the first three planetary models - Venus-Mercury, Jupiter-Mars and Jupiter-Saturn - will be examined. From the comparison, it is clear that key ideas are recovered and filled in, and stars missing in previous readings are given their planetary patterns. This seminar is highly practical, and without it serious study of Astrology is not possible.
