A tall, yellow-haired young European traveller calling himself “Mogor dell’Amore,” the Mughal of Love, arrives at the court of the real Grand Mughal, the Emperor Akbar, with a tale to tell that begins to obsess the whole imperial capital. The stranger claims to be the child of a lost Mughal princess, the youngest sister of Akbar’s grandfather Babar: Qara KÞoz, ‘Lady Black Eyes’, a great beauty believed to possess powers of enchantment and sorcery, who is taken captive first by an Uzbeg warlord, then by the Shah of Persia, and finally becomes the lover of a certain Argalia, a Florentine soldier of fortune, commander of the armies of the Ottoman Sultan. When Argalia returns home with his Mughal mistress the city is mesmerised by her presence, and much trouble ensues.
