"Tu che di gel sei cinta" ("You who are girdled with ice") is a soprano aria from act 3, scene 1, of Puccini's 1926 opera Turandot.
The words were written by Puccini himself while waiting for librettists Giuseppe Adami and Renato Simoni to deliver the next part of the libretto.
[1] In their work on Turandot, Ashbrook and Powers suggest that Puccini's failure to complete the opera much beyond this point resulted mainly from inadequate dramatic build-up for Turandot's last-minute change of heart combined with an overly successful treatment of the secondary character (i.e. Liù).
Liù counters Turandot with this aria, and later seized a dagger from a soldier's belt and stabs herself.
When told she is dead, he cries out in anguish that her offended spirit will take revenge, and Liù's cortège moves off, with Timur vowing to accompany her into "the night which knows no dawn".
