This book talks about the most important category, especially in the medieval era - about the End of the World, about the expectation of the End of the World. The main character of this book, as well as its main image, is Apocalypse. However, what is the Apocalypse? How did it come about? What are its origins? Why has the image of total collapse become so ubiquitous and even attractive? What do the Revelation of John the Evangelist, the paintings of Hieronymus Bosch and the sinister activities of Ivan the Terrible have in common? Turning to three characters who remain iconic today allows us to see the evolution of the medieval idea fix, the obsession with the idea of the End of the World. The reader will learn about how the Apocalypse manifested itself in fine art, architecture and direct political action.
