Italian opera revisited, history was retold and imagination was stimulated. The strength of it fell into a more violent era for opera: verismo, with "Cavalleria rusticana" by Pietro Mascagni and "Pagliacci" by Ruggero Leoncavallo. Some of the greatest Italian operas of the 20th century were written by Giacomo Puccini (1858–1924). These include "Manon Lescaut", "La bohème", "Tosca", "Madama Butterfly", "La fanciulla del West", "La rondine" and "Turandot", the last two being left unfinished. In 1926 and in 2002 Franco Alfano and Luciano Berio respectively attempted a completion of "Turandot", and in 1994 Lorenzo Ferrero completed the orchestration of the third version of
Messa (Puccini) in 1878 and was initially conceived by Puccini as a self-contained work. Puccini never published the full manuscript of the "Messa", and although well received at the time, it was not performed again until 1952 (first in Chicago and then in Naples). However, he re-used some of its themes in other works, such as the Agnus Dei in his opera "Manon Lescaut" and the Kyrie in "Edgar". At the end of World War II, Fr. Dante Del Fiorentino purchased an old copy of the manuscript of the Messa from the Vandini family in Lucca, imagining it was the original score.
