Synastry is the branch of astrology that tells us how we relate to other people. How Joe relates to Mary & what Mary may think of that. In this complete, classic guide to astrology & relationships, Robson goes far beyond the usual his planets vs: her planets. He studies the overall weight of the two charts, the fertility of the inner planets, the condition of the 7th house. He compares her-planets-to- his-planets as well as his-houses-to-her-houses. Robson considers how strongly the individual wants relationships - and how many, whether he/she will marry early or late - or t at all, the likelihood of children, the possibility of divorce. He gives rules for wedding dates. In an extraordinary appendix, he lists some 266 classified rules & aphorisms, culled from many ancient sources. This is perhaps the finest book ever written on astrology & relationships. About the author: Vivian Erwood Robson lived from 1890 to 1942. By trade he was a librarian. Like many librarians he had a natural bent for research, and, in his particular case, astrology. He studied ancient astrologers closely, including Ptolemy & William Lilly. His books on electional astrology, fixed stars, and relationships, are 20th century classics.
