Task: Question Answering
Input (English): Interest in Monteverdi revived in the late 18th and early 19th centuries among music scholars in Germany and Italy, although he was still regarded as essentially a historical curiosity. Wider interest in the music itself began in 1881, when Robert Eitner published a shortened version of the Orfeo score. Around this time Kurt Vogel scored the madrigals from the original manuscripts, but more critical interest was shown in the operas, following the discovery of the L'incoronazione manuscript in 1888 and that of Il ritorno in 1904. Largely through the efforts of Vincent d'Indy, all three operas were staged in one form or other, during the first quarter of the 20th century: L'Orfeo in May 1911, L'incoronazione in February 1913 and Il ritorno in May 1925.The Italian nationalist poet Gabriele D'Annunzio lauded Monteverdi and in his novel Il fuoco (1900) wrote of "il divino Claudio ... what a heroic soul, purely Italian in its essence!" His vision of Monteverdi as the true founder of Italian musical lyricism was adopted by musicians who worked with the regime of Benito Mussolini (1922–1945), including Francesco Malipiero, Luigi Dallapiccola, and Mario Labroca, who contrasted Monteverdi with the decadence of the music of Richard Strauss, Claude Debussy and Igor Stravinsky.In the years after the Second World War the operas began to be performed in the major opera houses, and eventually were established in the general repertory. The resuscitation of Monteverdi's sacred music took longer; he did not benefit from the Catholic Church's 19th-century revival of Renaissance music in the way that Palestrina did, perhaps, as Carter suggests, because Monteverdi was viewed chiefly as a secular composer. It was not until 1932 that the 1610 Vespers were published in a modern edition, followed by Redlich's revision two years later. Modern editions of the Selva morales and Missa e Salmi volumes were published respectively in 1940 and 1942.
