This done, Orlando rides on; when, arriving at a place where many roads cross, he meets a courier, and asking him news, learns that he is dispatched by Angelica, to solicit the aid of Sacripant, king of Circassia, in favour of her father, Galaphron, besieged by Agrican, emperor of Tartary, in Albracca. This Agrican had been an unsuccessful suitor to the damsel, whom he now pursues with arms. Orlando, who learns that he is within a day's journey of Albracca, now thinks that he is secure of Angelica, and proceeds with rapture towards her seat.

Thus journeying, he arrives at a bridge which united two mountains, and under which ran a foaming river. Here a damsel meets him with a goblet, and informs him, with much grace of demeanor, that it is the usage of the bridge to present the traveller with a cup, which she offers to Orlando, and which the paladin, in courtesy, drains. He has, however, no sooner swallowed the julep which sparkles in it, than his brain dances, and he is no longer conscious of the object of his journey, or even of his own existence. Under the influence of this fascination, he follows the damsel into a magnificent and marvellous palace.

Here the author leaves the count to return to Gradasso, who, deceived by the false herald that appointed him to meet Rinaldo upon the sea-shore at noon, in vain expects his arrival. He waits there till night, when he retires full of indignation at the supposed cowardice of his opponent. In the meantime, Ricciardetto (who had been left by his brother, Rinaldo, in charge of Charlemagne's army), on the paladin's departure for the false appointment according to the instructions he had received, in case of his not returning in a given time, withdraws Charles's forces from Marsilius's camp, and returns to France.

Gano immediately cries out upon Rinaldo's treason, and all is dismay. On the other part, Marsilius, thus deserted, has no means of safety, but in making peace with Gradasso, and consenting to hold Spain as his liegeman. In consequence of his so doing, Gradasso, strengthened by the accession of Marsilius, with Grandonio and his other vassal kings, marches upon Paris. Charlemagne, with all his peerage, sallies to encounter him; but his army experiences a disastrous rout, and he, with almost all his paladins, is captured; while Paris is immediately invested by the invaders.

Gradasso, however, does not abuse his victory: he takes Charles by the hand, seats him by his side, and tells him he wars only for honour. Hence he renounces all conquests, but insists on the monarch promising him Bayardo and Durindana, both the property of his vassals, the first of which, as he maintained, was already forfeited by the treason of Rinaldo. To this; Charlemagne and his peers in acknowledgment of their defeat, were to remain his prisoners for a day: Bayardo, who had been brought back by Ricciardetto, was to be forthwith delivered up, and Durindana consigned to Gradasso in Sericana, upon the return of Orlando to France. To these terms Charlemagne readily accedes, and sends for the horse to Paris.

Here, Astolpho had assumed the command, having obtained his freedom during the confusion, which followed upon the rout of Charlemagne's army, and asserted an authority which, in the absence of the other peers, there was no one to dispute.

He receives with great indignation the messenger dispatched for Bayardo, and throws him into prison; answering the embassy by a herald, who says, on the part of Astolpho, "that Charles has no right in the steed; but that Gradasso may come and fight for him; in which case he will meet him in the field."

The next day the two knights encounter, having previously established the conditions of their combat. The enchanted lance performs a new wonder; and Gradasso, the terrible Gradasso, is unhorsed.

According to their previous agreement, Gradasso is to give up his prisoners, and return to his kingdom of Sericana. Astolpho, however, begs him not to spoil a jest which he wishes to put upon Charlemagne and his paladins, by making them believe that the issue of the duel had been different from what it was, and that they, therefore, (in consequence of the first proffer of Gradasso not having been acceded to,) were still the prisoners of that sovereign. When Astolpho has sufficiently bantered both king, count, and bishop (for Turpin was amongst the captives, and one of the objects of his raillery), he falls upon his knees, begs pardon of Charles for his irreverence, and observes, that as he is ill looked upon in his court, he will leave the field to Gano, and set out on the morrow in search of his cousins Orlando and Rinaldo. Having said this, Charles and his peers are freed, and Gano is getting into his saddle; when he is brought back by Astolpho, who observes, that he only gives him his liberty, (since the disposal of all is at his option,) on condition of his swearing before Charles, to constitute himself his prisoner for four days, whenever he should enjoin it. Charles undertakes for his compliance with such a requisition, and seeks to detain Astolpho with the bribe of Ireland; but the duke is inflexible, and departs. Gradasso also returns into Sericana.

The author now returns to Rinaldo, who was landed by the self-piloted boat in what was, it seems, denominated The Joyous Garden. He is scarcely disembarked, before a lady appears, who takes him by the hand, and conducts him into a palace, where he is served by attendant damsels, with every sort of luxury and magnificence. At last, the chief of the servants tells him, that all this is his which he surveys, being the present of a lady, who, to have his love, has brought him out of Spain. While Rinaldo stands lost in astonishment, the name of Angelica, who is proclaimed by this man to be the mistress of the palace, breaks the charm, and he flies in fury through the garden, till, arriving at the landing-place, he leaps again into his pinnace. The bark, however, remains immoveable, and he is about to cast himself into the sea in despair, when it darts from the shore and traverses the waves.
