It was during this final 20th century pop revival of Western astrology that Sun Sign Astrology, ideas on karma and reincarnation, and the reading of daily horoscopes first began coming back into vogue.According to esteemed astrologer, Dane Rudhyar, at the beginning of the 1930's, astrologer Paul Clancy decided that popularizing astrology was to be his life mission. When Clancy's magazine "American Astrology" became a huge success in 1934, it started a new "epoch" in astrology. It was primarily Clancy's venture in "American Astrology" that brought about the popularity of daily and/or weekly astrological horoscope columns, with readings of the twelve signs, to appear in the newspapers and periodicals throughout the United States and Europe. (from the preface of Astrology, The Divine Science by written by Marcia Moore and Mark Douglas)
What the esteemed and quite respected astrologer, Dane Rudhyar, failed to mention in his preface is that it was none other than he, Dane Rudhyar, who was the original writer of these popular "American Astrology" horoscopes.
