these stories, believed to be inspired by Nizami, features a cold princess named Turandokht. However, it has been speculated that many of de la Croix's 'translated' stories were his own original creations, with no actual basis in Middle Eastern cultures. De la Croix's story was adapted into a play,Turandot, by the Italian playwright Carlo Gozzi in 1762, which was then adapted by Friedrich Schiller into another play in 1801. It was Schiller's version that inspired Puccini to write the opera. Puccini began working on Turandot in March 1920 after meeting with librettists Giuseppe Adami and Renato Simoni. In his impatience, he began composition in January 1921, before Adami and Simoni had produced the text for the libretto. As with Madama Butterfly, Puccini strove for a semblance of authenticity by using music from the region, even commissioning a set of thirteen custom-made gongs. Baron Edoardo Fassini-Camossi, the former Italian diplomat to China, gave Puccini a music box that played 4 Chinese melodies. Puccini incorporated three of these melodies into his opera, the most memorable of which is the folk melody "Mò Li Hūa (茉莉花)" ('Jasmine Flower'). Mò Li Hūa serves as a leitmotif for Princess Turandot. In total, eight of the themes from Turandot appear to be based on traditional Chinese music and anthems. By March 1924, Puccini had completed the opera up to the final duet. However, he was dissatisfied with the text of the final duet, and did not continue until 8 October, when he chose Adami's fourth version of the duet text. Two days later, he was diagnosed with throat cancer. Puccini seems to have had some inkling of the seriousness of his condition: before leaving for Brussels for treatment, he visited Arturo Toscanini and begged him, "Don't let my Turandot die." He died of a heart attack on 29 November 1924. Completion of the score after Puccini's death When Puccini died, the first two of the three acts were fully composed, including the orchestration. Puccini had composed and fully orchestrated Act Three up until Liù's death and funeral cortege. In the sense of finished music, this was the last music composed by Puccini. He left behind 36 pages of sketches on 23 sheets for the end of Turandot. Some sketches were in the form of "piano-vocal" or "short score", including vocal lines with "two to four staves of accompaniment with occasional notes on orchestration." These sketches provided
