In the late 19th century, a realistic literary movement called ''Verismo'' played a major role in Italian literature; Giovanni Verga and Luigi Capuana were its main exponents. In the same period, Emilio Salgari, writer of action-adventure swashbucklers and a pioneer of science fiction, published his ''Sandokan'' series. In 1883, Carlo Collodi also published the novel ''The Adventures of Pinocchio'', the most celebrated children's classic by an Italian author and one the most translated non-religious books in the world. A movement called Futurism influenced Italian literature in the early 20th century. Filippo Tommaso Marinetti wrote ''Manifesto of Futurism'', called for the use of language and metaphors that glorified the speed, dynamism, and violence of the machine age.
