Turandot is the beautiful, yet cruel, daughter of the Emperor Altoum.
It is dusk in Peking. From the top of a wall of the Imperial Palace a mandarin announces Turandot’s edict to the people. She says she will marry whichever suitor of blue blood manages to solve the three riddles she devises. Those who fail will be decapitated. Like the others who have preceded him, the Prince of Persia has also failed the test and will be executed when the moon rises.
Among the crowd outside the palace, there is an old man who is accompanied by his loyal slave, Liù. He is Timur, ex- king of the Tartars, now in exile and practically blind. In the turmoil he falls to the ground. Liù pleads for help and a young man rushes over to them, pushing his way through the crowd. Lo and behold, it is Prince Calaf, Timur’s son. He, too, has escaped from their homeland and is travelling incognito so as not to arouse suspicion. The two men are overcome at meeting up again after so long. Timur recounts how Liù has helped him during his exile. The prince acknowledges his gratitude and asks her why she has been so dedicated to his father. She replies with disarming sweetness that one day a long time ago, his father had smiled at her and ever since then, she has secretly loved him.
