his name, Don Juan calls himself "Juanna". The narrator tells that Dudù is a "kind of sleepy Venus ... very fit to murder sleep.... Her talents were of the more silent class ... pensive...." Dudù gives Juanna a chaste kiss and undresses. At three o'clock in the morning, whilst the harem sleep, Dudù screams and awakens agitated, whilst the snoring Juanna continues asleep. The odalisques ask the reason for her screams, and Dudù relates a sexually suggestive dream, of being in a wood, like Dante, of dislodging a golden apple that tenaciously clings to the bough, of almost biting that forbidden fruit, when a bee flies out from the apple and stings her to the heart. The matron of the seraglio decides to place Juanna with another odalisque, but Dudù begs to keep her as companion in her couch. The narrator Byron does not know why Dudù screamed whilst asleep. In the morning, the sultana Gulbeyaz asks Baba to tell her how Don Juan, as "Juanna", passed the night at the harem. Baba tells of Juana's night, but omits details about Dudù and her dream.

In the event, John Johnson presents himself to Suvorov (with whom he fought in battle at Widdin, in Bulgaria) and introduces his friend Don Juan, saying that both men are ready to join the Christian fight against the pagan Turks. Marshal Suvorov is very unhappy that John and Juan
