Argalia consents, and dies; while Ferrau, who is a Saracen, hearing of the misfortunes of his sovereign Marsiglio, who is attacked by Gradasso, king of Sericana, gives up the pursuit of Angelica, and sets out for Spain. Angelica returns to India, and Orlando departs in quest of her. Charlemagne goes to the assistance of Marsiglio against Gradasso, who himself is a wonder of martial prowess, and is attended by an innumerable army, and several vast and fierce giants. Rinaldo has returned to court, and accompanies his imperial master: during the battle that ensues, he encounters Gradasso; but their single combat is interrupted by the hurry of the fight, and they agree to meet in duel the next day on foot, in a solitary place by the sea-side. Gradasso's great object is to win Orlando's sword Durindana, and Rinaldo's horse Bajardo: the latter is to be his prize, if he overcomes Rinaldo on the following day. Angelica meanwhile, burning with love for Rinaldo, revolves many schemes for bringing him to her side. She has in her power his cousin Malagigi (Maugis), who is a great enchanter. She set him at liberty, on condition that he shall bring Rinaldo to her. Malagigi first tries to persuade his cousin; but the chilly waters have wrought too powerfully, and the very name of Angelica is odious to him. Malagigi has recourse to stratagem. When Rinaldo keeps his appointment the next morning with Gradasso, he finds the sea-shore solitary: a little boat, tenantless, is anchored near the beach. Malagigi sends a fiend, in the shape of Gradasso, who, after a mock combat, take refuge in the pinnace, followed by Rinaldo. The boat drifts out to sea, the fiend vanishes, and Rinaldo is hurried away across the ocean, till he arrives near a palace and garden, where the vessel lightly drifts on shore. Orlando wanders about to find Angelica, and hears that she is at Albracca, a castle of Catay. But he is unable to reach her, detained by a variety of adventures and enchantments, through which he is at last deprived of all memory or knowledge, and brought to a magnificent palace, where he is left. Charlemagne meanwhile is freed from Gradasso by means of Argalia's enchanted lance, which, falling into Astolfo's possession, he works miracles, unhorses the mighty king, and a peace being agreed upon, he sets out in search of Orlando and Rinaldo. Poor Rinaldo is tempted meanwhile to soften towards Angelica, but in vain. The luxuries of an enchanted palace are wasted on him, and he is exposed to the most frightful dangers, from which Angelica delivers him; but still he scorns and leaves her, while she returns disconsolate to Albracca.
