The caves east of Otranto are a labyrinth of rocky passages and former hermit retreats, extending behind a forest toward the sea coast. Matilda identifies them as a place where Theodore might hide from the search for him; when he enters them later, the same concealed landscape brings him face to face with Isabella, fleeing from Manfred. The caves therefore serve both as a practical refuge and as the setting for a consequential encounter between escape and pursuit.

Setting and Access

Matilda describes the caves as a chain of rocks east of the castle, behind a forest, hollowed into a labyrinth of caverns that reaches the coast. Her directions distinguish this eastern route from the town and the castle’s western side, where Manfred and his companions are expected to search. The landscape offers more than hiding places: Theodore might remain concealed there until he could signal a vessel to come ashore and carry him away.

The geography is described through movement and concealment. A forest screens the approach; the rocky passages divide into a labyrinth; and the route ultimately reaches the sea. Matilda’s instructions make the caves legible as an escape corridor, linking the castle’s immediate dangers to the possibility of departure by ship. She sends Theodore toward the opposite quarter from the anticipated search, turning knowledge of the surrounding terrain into a means of evading capture.

Refuge and Reported Haunting

The caves had formerly served as a retreat for hermits. By the time Theodore explores them, however, people in the surrounding country report that evil spirits haunt them. That reputation gives the old religious refuge a disturbing double character: its history suggests solitude and sanctuary, while local rumor casts its secluded passages as a place of supernatural danger.

Theodore enters without treating the haunting as established fact. Although grounded in his religious faith, he sees no reason to suppose that good people are abandoned without cause to malign supernatural powers. Robbers seem to him a more likely danger than infernal agents said to mislead travelers. The distinction matters: he is not indifferent to danger, but he approaches the caves with practical suspicion rather than surrendering to the local story about them.

Theodore’s Exploration

After Matilda releases him from the castle, Theodore goes to the convent to tell his father of his deliverance. He learns that his father, Jerome, is absent, and hears that Isabella is being pursued, but the monks cannot tell him which way she has gone. Though he wishes to help her, his attachment to Matilda keeps him from searching far from the castle and monastery; he even persuades himself that filial feeling is the chief reason he remains nearby.

Until Jerome returns at night, Theodore eventually follows Matilda’s directions and heads into the forest. He seeks its gloomiest shade, in keeping with the melancholy of his thoughts, and wanders into the caves. Curiosity about the rumored haunting draws him farther into the labyrinth. There he thinks he hears someone retreating ahead of him, and follows the faint rustling sound, using his drawn sabre and armored presence as he advances. He believes the person fleeing has noticed him as well.

The pursuit ends when a woman falls breathless before him. Theodore hastens to raise her and tries to calm her fear, promising to defend her rather than harm her. The voice and appearance of the stranger lead to recognition: she is Isabella, whom he has previously helped. When she identifies him as the unknown man she met in the castle vault, he refuses to let her return to Manfred’s power and urges her deeper into the caves, away from their entrance and immediate danger.

Concealment, Pursuit, and Significance

The caves do not offer safety without complications. Isabella worries that being found alone with Theodore in the secluded passages would expose her to a censorious judgment of her conduct. Theodore answers by explaining that he intends to place her in a private cavity and guard the entrance at risk to his own life. He also admits that, despite his admiration for her, his affections belong to someone else: Matilda. Before he can say more, voices searching for Isabella approach, and he leaves her concealed to intercept them.

At the mouth of the cavern, Theodore encounters an armed knight speaking with a peasant who has seen a lady enter the rocky passes. As the knight prepares to pursue her, Theodore blocks the way with his sword drawn and warns him not to advance at his peril. The encounter makes the caves’ double function plain: they conceal a fugitive, but their entrance is also a point where pursuit can be challenged. Their dark, divided passages intensify uncertainty, while the approach from the castle and the prospect of the coast give concealment a clear practical purpose.

The same caves thus connect several pressures in Theodore’s story: his escape from the castle, his enduring closeness to Matilda, his wish to protect Isabella, and the threat of Manfred’s authority. Their former use by hermits and their reported haunting give the refuge a charged history, but the decisive dangers in this episode come from human pursuit and the possibility of being discovered. From the forest’s gloomy shade to the armed confrontation at the entrance, the labyrinth becomes the setting where a hidden route of flight leads directly into conflict.
