Synastry

Synastry

Synastry refers to the branch of astrology that compares two natal charts to evaluate romantic, social, or professional compatibility and interpersonal dynamics. By overlaying one individual’s planetary placements, angles, and house positions onto another person’s chart, this method identifies areas of attraction, emotional resonance, shared strengths, potential conflict, and mutual psychological impact within a relationship.

DIE SYNASTRIE – HOROSKOPVERGLEICH & SCHNITTENPUNKTHOROSKOPE

aka Synastry (Chart Comparison) & Midpoint Charts

Synastry, Composite Charts, and Relationship Astrology. This German-language archival document is a instructional manuscript titled “DIE SYNASTRIE (HOROSKOPSVERGLEICH) & SCHNITTPUNKTHOROSKOPE” by Marion D. March. March provides a practical methodology for evaluating inter-personal dynamics and compatibility through direct chart comparisons (synastry) and midpoint composite charts (Schnittpunkthoroskope). The lecture covers house overlays, new geometric aspect patterns formed between charts (T-squares, Grand Crosses, Yods, and Grand Trines), Lunar Node connections, and primary planet-to-planet interactions. Case studies feature notable historical and celebrity couples, including Prince Rainier and Grace Kelly, Sir Laurence Olivier and Vivien Leigh, Marlene Dietrich and Erich Maria Remarque, Marilyn Monroe and Arthur Miller, Eleonora Duse and Gabriele d’Annunzio, Ingrid Bergman and Roberto Rossellini, Robert and Clara Schumann, and Benito Mussolini with Rachele Mussolini and Clara Petacci. The document also includes reference handouts detailing synastry house interpretations, composite house/planet meanings, and illustrative chart overlays.
