The tragedy of the Holocaust was an extremely sensitive topic for Poland after World War II. Despite the well-known facts of Poles helping Jews, the majority of the Polish population, according to the author of this book, occupied the position of "outside observers" of the Holocaust. Such a shameful experience was difficult to comprehend for contemporaries of the war and their descendants, who were more willing to think of themselves in terms of victims and heroes. The problem was aggravated by censorship restrictions imposed by the authorities of communist Poland. Grzegorz Niziołek's book is dedicated to the history of the tense relations that linked the topic of the Holocaust and Polish theater. It critically analyzes the play that takes place both on and off stage - the play of memory and amnesia, knowledge and its absence. The author carefully examines the problem of the "blindness" of the theater in relation to the Holocaust, but pays even more attention to examples when playwrights and directors at least latently touched on this topic. According to the researcher, it is precisely the forms of allegorical conversation about the Holocaust that form the basis of the most outstanding phenomena of Polish post-war theatre, including the performances of Leon Schiller, Jerzy Grotowski, Józef Szajna, Erwin Axer, Tadeusz Kantor, Andrzej Wajda and others. Grzegorz Niziołek is the head of the theatre and drama department at the Faculty of Polish Studies at the Jagiellonian University in Krakow.
