For an astrologer of late antiquity, the most important question when interpreting a horoscope was: Was the horoscope owner born during the day or at night? Robert Hand explores this question and demonstrates through his extensive study of sources the variety of interpretations that arise from this approach. In the second part, he addresses the oldest house system, the whole sign houses. Here too, he shows, using sources that are otherwise difficult to access, how the astrological houses have developed. Both methods are supported by horoscope examples, allowing you to immediately recognize the practical benefits for your own interpretations. Through a successful synthesis of classic and modern elements, Robert Hand has written a groundbreaking book for the astrology of the future.
