Lalla-Rookh, the title of a poem by Moore, from the name of the heroine, the daughter of the Mogul Emperor, Aurungzebe; betrothed to the young king of Bacharia, she goes forth to meet him, but her heart having been smitten by a poet she meets on the way, as she enters the palace of her bridegroom she swoons away, but reviving at the sound of a familiar voice she wakes up with rapture to find that the poet of her affection was none other than the prince to whom she was betrothed.
