The Posthumous Memoirs of Bras Cubas (Portuguese: Memorias Posthumas de Braz Cubas modern spelling Memórias Póstumas de Brás Cubas), often subtitled as the Epitaph of a Small Winner, is a novel by the Brazilian writer Joaquim Maria Machado de Assis.
Published in 1881, the novel has a unique style of short, erratic chapters shifting in tone and style. Instead of the clear and logical construction of a normal nineteenth-century realist novel, the novel makes use of surreal devices of metaphor and playful narrative construction.
