The Wall is a 1939 collection of five short stories by Jean-Paul Sartre exploring characters facing death, madness, violence, and questions of authenticity. The title story follows Pablo Ibbieta, a prisoner sentenced to death during the Spanish Civil War.
The Wall was published in 1939. Four of its five stories had already appeared in French journals before this book brought them together.
Sartre dedicated The Wall to his companion Olga Kosakiewicz. She was a former student of Simone de Beauvoir.
Pablo Ibbieta is sentenced to death alongside two other men during the Spanish Civil War and is offered freedom if he reveals the whereabouts of his comrade Ramón Gris. Pablo gives false information about Gris's location, but Gris has since moved to that very spot, so Gris is shot there and Pablo's life is spared instead.
A 1967 film titled The Wall was based on the title story, and a 2016 film titled The Childhood of a Leader was based on the story of the same name.
The Wall contains five short stories: 'The Wall', 'The Room', 'Erostratus', 'Intimacy', and 'The Childhood of a Leader'.
