Die Harmonie der Welt
Johannes Kepler serves Emperor Rudolf II, supports himself by casting horoscopes, and pursues a theory of universal harmony. He marries Susanne, faces religious conflict, and fights for six years to save his mother Katharina from a witchcraft accusation. Wallenstein later hires Kepler as his astrologer. As political turmoil grows under Ferdinand II and Swedish forces invade, the ailing Kepler warns the emperor’s electors in vain and dies. The characters’ roles as celestial bodies are reflected in the opera’s final vision of their ordered orbits.
