A classic of Austrian prose, Leo Perutz (1882–1957) is a recognized master of expressionism and “magical” literature.” His works are distinguished by an exciting plot, a detective plot with an irrational denouement and an increased interest in mental pathologies. The novel “Judas of the Last Supper,” which received rave reviews from H. L. Borges, is dedicated to the mystical history of the creation of Leonardo’s famous masterpiece. Are there boundaries between the real and the incomprehensible? Where do the limits of reason end and the realm of the supernatural begin? These and other questions that have always excited people's minds are clearly reflected in Perutz's novel.
