In this unhappy frame of mind he attacks everybody he meets, and after many victories is defeated in a battle with the Christians.

During this last encounter Rogero is too grievously wounded to be able to join Bradamant, who, hearing a fair lady is nursing her lover, is consumed by jealousy.

She therefore--notwithstanding her mother's decree--sets out in the garb of a knight to challenge her recreant lover and defeat him by means of her magic lance.
After unhorsing on the way all those who venture to tilt with her, Bradamant meets Rogero, who, recognizing her in the midst of their duel, flatly refuses to continue the fight, and implores her to accompany him into a neighboring forest, where he promises to explain all to her satisfaction.

They are, however, followed thither by the maiden who has nursed Rogero, who, jealous in her turn, now attacks Bradamant.

Rogero, infuriated by Bradamant's imminent peril, is about to slay his nurse remorselessly, when an enchanter's voice proclaims she is his sister, stolen in infancy! All excuse for mutual jealousy being thus removed, the two women agree to join forces and fight in behalf of Charlemagne until Rogero can discharge his obligations to the Saracens, receive baptism, and join the Christian ranks.
Meantime Astolfo has ridden off on the hippogriff to the earthly paradise, where he has interviews with sundry saints and apostles, and whence St.John conveys him up to the moon.
