The central narrative in Bojardo's epic, the Orlando Innamorato, relates how the appearance of the beautiful Angelica at the court of Charlemagne completely turned the heads of all the noble paladins present, notably Orlando and Rinaldo. These two cousins and brothers-in-arms now become hated rivals, and set out in pursuit of the fair maiden when she returns to her native country. Much time passes before the two knights meet, and when this finally does occur, it is before Albracca, Angelica's castle, where she is besieged by another lover, Agricane, King of Tartary. The meeting is stormy, as was to be foreseen, and a duel is begun which lasts for two days, and which would have ended badly for Rinaldo had not Angelica, who just then is in love with him, held back the blow that would have wounded him mortally. She knows that Rinaldo is safe only if Orlando can be gotten out of the way, and to do this successfully she sends the latter on a perilous and distant expedition. Among the many adventures which he encounters on this journey is the destruction of an enchanted garden which had been fabricated by an enchantress named Falerina. Orlando's impulse is to slay her as well, but his mind is changed when he learns that her death would have as consequence the death of many knights and ladies who are kept prisoners in a tower. In exchange for her life she promises to lead him to that prison (ii–v, 1–24). When they arrive there Orlando sees hanging on a tree beyond the moat the armor of his cousin Rinaldo, and, believing him dead, remorse for his former quarrels with him seizes him, and he rushes over the bridge to engage battle with Aridano, the guardian of the tower. The two antagoniste clutch, and soon roll down the shore into the enchanted lake which surrounds the prison (ii–vii, 32–63). They descend through the water until they arrive on dry ground, a meadow, lighted up by the rays of the sun, that break through the water above them. Here the battle continues, until Orlando succeeds in slaying his enemy. Then he looks about him for a way of escape. He is surrounded on every side by mountainshore and rocks; but on one side he notices a door cut into the rock, and near that entrance he sees chiselled a picture of the labyrinth and its history with the minotaur, and not far from this another picture, showing a maiden wounded in the breast by a dart of love thrown by a youth. This should have taught him the manner of escape, but he passes on without heeding its meaning. Soon he arrives at a river and a narrow bridge, on either side of which stand two iron figures, armed. Beyond it in the plain is placed the treasure of the Fata Morgana. He attempts to cross this bridge, but at every trial the two iron figures demolish it, and a new bridge at once rises in the place of the old one. Finally, with a tremendous leap he clears the river, and now he finds himself near the coveted treasure. After many wonderful incidents, which it is not to the purpose to relate he arrives near the prison where Rinaldo is held with other knights. This latter, it should be stated, had also left Angelica after his duel with Orlando, and arrived here by a shorter way. As Orlando approaches this prison, he comes to a fissure in the rock, into which he enters, and which leads him to a door.
