Instead of becoming one of her permanent victims, Rogero, warned by the myrtle to which he ties his steed, prevails upon her to release her captives, and after many adventures is borne by the same hippogriff to the island of Ebuda, where a maiden is daily sacrificed to a cannibal Orc.

When Rogero discovers that the present victim is Angelica, he promptly delivers her and conveys her to Brittany.
Meantime Orlando, mad with love, is vainly seeking Angelica.

He too visits Ebuda--but too late to meet her there--and delivers another maiden.

Then he returns to France to find Charlemagne so sorely pressed by foes, that he has implored St.Michael to interfere in his behalf.

This archangel, cleverly enlisting the services of Silence and Discord, brings back Rinaldo and other knights, who drive away the disintegrating pagan force after sundry bloody encounters.
