The author takes you on a journey through the stars and constellations that have been present in the sky for thousands of years and that have been a subject of fascination for astrologers for centuries. In order to learn about the influences of the individual stars on a human in a calculated horoscope, a knowledge of the constellations to which they belong, is required. With many examples of birth charts of well-known people, it is shown how the constellations act when one or more planets from the birth chart are in conjunction with the individual stars of that constellation. How the individual fixed stars work in a horoscope is described in great detail by means of many examples, accompanied by numerous pictures. A "revelation" of the well-known "Via Combusta" from horary astrology is presented in one of the chapters. Also some room has been created for the significance of individual stars and constellations in mundane astrology, which tries to explain events in cities and countries.
