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.
