An Italian form of naturalism, best exemplified by the novels and stories written in the 1880s by the Sicilian writer Giovanni Verga; these document the harsh lives of the Sicilian poor. Another notable verist of this period is the short-story writer Federico de Roberto. Verismo, through Verga's story Cavalleria rusticana, had a significant influence on Italian opera (notably on Puccini), and later upon the emergence of neo-realism. In English, the term verism is sometimes applied to realism as a critical doctrine. Adjective: veristic.
