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.
