Turandot premiered at La Scala in Milan on 25 April 1926, almost a year and a half after Puccini’s death. Puccini’s friend Arturo Toscanini, who had worked on the score with the composer during the last months of Puccini’s life, conducted the premiere. As is widely recorded, when the opera reached the last note written by Puccini, Toscanini ended the performance. What he said at the time has been variously reported, from the poetic “Here death triumphed over art” to the poigniant “For me, the work ends here.” An eyewitness quoted in a recent biography puts it somewhere between the two: “Here ends the opera, because at this point the maestro was dead.”

“Yes, as we said to begin with, “The Mikado” is a frank success. It is great nonsense, no doubt; but then it is the very funniest fooling to be seen. And so pretty, too!”  ~unsigned review from “The Academy”, March 28 1885  http://www.savoyoperas.org.uk/mikado/mik3.html

“Mr. Gilbert has once more exhibited his facility for seizing upon a subject occupying a considerable share of public attention, and turning it to humorous account. Japanese art is extremely fashionable just at present, and the manners and customs of this strange race may be studied with advantage at Knightsbridge. But it is our home political and social life that is principally caricatured in ‘The Mikado,’ and amid much that is incisive and telling we find obvious reminiscences of earlier productions by the same hand.”
