As a novelist, Hermann Broch (1886-1951) was a poeta doctus who also made a name for himself as a philosophical essayist, human rights theoretist, mass psychologist and literary critic. At the same time, he occupied himself with art, architecture, music and film. The present volume is the first study to profile Broch’s interest in the arts and to examine their complex influence on his work. The papers demonstrate how particularly strongly the arts affected each other in works of 20th century classical modern literature in the way of intertextuality, ecphrasis and interpenetration.
