Rudolf II: The Life and Legend of the Mad Emperor offers a fresh perspective on the Habsburg ruler, shedding new light on a reign often coloured by myths of madness. 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 his interests in astrology, alchemy and magic, Thomas DaCosta Kaufmann offers new insights into Rudolf's support for scientific endeavours and his quest for power. It 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. This book will appeal to a diverse audience, including enthusiasts of the occult, as well as those fascinated by Renaissance history, the Habsburg dynasty and art history.
