A reinterpretation of the Habsburgian ruler's reign as exemplary rather than reclusive. Rudolf II offers a fresh perspective on the Habsburg ruler, shedding new light on a reign often colored by myths of madness. Thomas DaCosta Kaufmann argues that, contrary to popular belief, Rudolf was not a passive recluse but an engaged monarch, navigating the complexities of state affairs with a moderate hand amid turbulent times. By contextualizing Rudolf's interests in astrology, alchemy, and magic, this book offers new insights into the emperor's support for scientific endeavors and his quest for power. Kaufmann also demonstrates that Rudolf's assembling of the greatest Kunstkammer and painting collection of his time and his patronage of artists were essential elements of Renaissance rulership.
