“Grand Italian Theater: for me, a true event. During these four hours, I understood more than I usually do in four weeks. Honor to Mr. Sonzogno!” (Friedrich Nietzsche, in a letter from Nice to his friend Peter Gast, 1887)
“Sonzogno, the great music publisher whose competition revealed Mascagni’s talent, has brought new works to the Universal Exposition: remarkable signs of the times!” (Eduard Hanslick, Fünf Jahre Musik, Berlin, Verein für Deutsche Literatur, 1895)
