March 1868, and prestige productions in most other Italian opera houses followed, but it did not become a popular success. The length was a particular problem, and subsequent performances were generally heavily cut. The first production in Naples in 1871 was indisputably a failure. 1872 revisions for Naples Following the unsuccessful performance in Naples in 1871, Verdi was persuaded to visit the city for further performances in November / December 1872, and he made two more modifications to the score: (a) a revision of the closing two-thirds of the Philippe-Rodrique duet in Act 2, Scene 2 (to Italian verses, almost certainly by Antonio Ghislanzoni), which replaced some of the previously cut material, and (b) the removal of the allegro marziale section of the final Elisabeth-Carlos duet (replaced with an 8-bar patch). These are the only portions of the opera that were composed to an Italian rather than a French text. According to Julian Budden, Verdi "was to regret both modifications". Ricordi incorporated the revisions into later prints of the opera without changing the plate numbers. This subsequently confused some authors, e.g. Francis Toye and Ernest Newman, who dated them to 1883. 1882/83 and 1886 revisions: "Milan version" and "Modena version" The idea of reducing the scope and scale of Don Carlos had originally come to Verdi in 1875, partly as a result of his having heard reports of productions, such as Costa's, which had removed Act 1 and the ballet and introduced cuts to other parts of the opera. By April 1882, he was in Paris where he was ready to make changes. He was already familiar with the work of Charles-Louis-Étienne Nuitter, who had worked on French translations of Macbeth, La forza del destino and Aida with du Locle, and the three proceeded to spend nine months on major revisions of the French text and the music to create a four-act version. This omitted Act 1 and the ballet, and was completed by March 1883. An Italian translation of this revised French text, re-using much of the original 1866 translation by de Lauzières, was made by . The La Scala première of the 1883 revised version took place on 10 January 1884 in Italian. Although Verdi had accepted the need to remove the first act, it seems that he changed his mind and allowed a performance which presented the "Fontainebleau" first act along with the revised four-act version.
