The Posthumous Memoirs of Brás Cubas (Portuguese: Memorias Posthumas de Braz Cubas, modern spelling Memórias Póstumas de Brás Cubas), also translated as Epitaph of a Small Winner, is a novel by the Brazilian writer Joaquim Maria Machado de Assis (born in Rio de Janeiro City, then Imperial Capital of Brazil).
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. It is considered the first novel of the realist movement in Brazil.
