Vienna cultural context
Three famous names who belonged to different Viennas
Mozart, Beethoven and Freud lived and worked in Vienna in different periods and fields: Classical music, Romantic-era composition and the development of psychoanalysis. They did not form one historical circle. This quest brings their legacies together through fictional letters and clues, using real city associations without inventing a meeting among all three men. Playable languages: German, English.
