Zaire's love increases with the indulgent tenderness of her lover. She casts herself in tears at his feet and beseeches him to defer the marriage till the morrow. She calculates that her brother will then be gone—that she will have received baptism—that she will have acquired the strength to resist; she even flatters herself that the Christian religion will permit her to love a man so generous, so virtuous, to whom nothing is wanting but to be a Christian. Struck with these ideas she speaks to Orosman with a tenderness so natural, a grief so genuine, that he yields again, and agrees to live this one day without her.

The letter is delivered to Zaire: she reads it trembling, and after long hesitating, tells the slave that she will expect Nerestan, and orders that he shall be admitted. Of all this the slave informs Orosman.
The unhappy Soldan goes wild with grief. Weeping,
