Peredur's trials at the Castle of Wonders

Peredur's trials at the Castle of Wonders transform a search for information into a sequence of contests whose apparent randomness conceals a personal purpose. He enters the lakeside castle to find a chessboard playing by itself; his impulsive destruction of it brings a demand for restitution, then a succession of dangerous tasks. The final encounter links these marvels to the bloody head and bleeding lance that had appeared earlier, and to a prediction that Peredur would avenge his family.

The Quest and the Chessboard

After Peredur refuses an offer of marriage and reward, he explains that he is seeking the Castle of Wonders. The maiden who has helped him gives him directions and provisions, and describes the destination as a castle in the middle of a lake. Its wonders are unknown, she says, though the name is widely used. This lack of explanation makes the castle less a clearly defined destination than an invitation to enter what cannot yet be understood. The gate and hall stand open. Inside, Peredur sees chessmen moving against one another without players. When the side he favors loses, the opposing pieces cry out as if they were living people. Angered by the result, he gathers the chessmen in his lap and throws the board into the lake. The act is decisive but not considered a victory: the black maiden who appears afterward tells him that he has caused the Empress of Cristinobyl the Great to lose a board she would not have surrendered for her entire empire. Peredur's response to the uncanny game creates the next stage of his quest.

Restitution and the Black Man

The maiden says the chessboard can be recovered at the Castle of Ysbidinongyl, where a black man is laying waste to the Empress's lands. She warns Peredur that he may not return alive, but agrees to show him the way. At the castle, Peredur defeats the black man, who asks for mercy. Peredur grants it on the condition that the chessboard be restored to its former place. The maiden rejects this compromise: the board has not returned, and the black man continues to devastate the Empress's possessions. Peredur goes back and kills him. The episode gives the quest a repeated pattern: Peredur initially makes a choice that seems to resolve a danger, only to learn that the condition he imposed has not repaired the original harm. His first mercy depends on the black man restoring the board; when that fails, he returns to the task and uses force. The changing demand also makes the maiden's guidance unsettling. She leads Peredur onward, but her instructions do not simply bring each encounter to a clean conclusion.

The Stag and the Challenge at the Grove

Back at the palace, Peredur is told that he cannot see the Empress unless he kills a stag in the forest. The animal is described as swift as a bird, with a spear-length horn sharp enough to threaten whatever it meets. It damages the best trees, kills other animals, and leaves those that survive without food. Each night it also drinks the fishpond dry, leaving the fish exposed until the water returns. The danger is therefore not confined to a single opponent: the stag's presence disrupts the forest and the pond alike. Because no mortal has entered the forest for more than a year, the maiden provides the Empress's little dog to rouse the stag and drive it toward Peredur. The animal attacks, but Peredur lets it pass and cuts off its head with his sword. A woman on horseback arrives while he is examining the head. She gathers the dog into the fold of her cap and reproaches Peredur for killing what she considers the finest jewel in her domain. Although he explains that he was asked to do it, she offers a way to gain her friendship: he must go to a grove, find a cromlech, and challenge a man there three times. A black man rises from beneath the cromlech on a bony horse, both rider and horse clad in heavy rusty armour. Peredur repeatedly throws the fighter to the ground, but each time the man returns to his saddle. When Peredur dismounts and draws his sword, the black man vanishes, taking both horses with him. The encounter resists the ordinary terms of a contest: physical advantage does not settle it, and the disappearance leaves Peredur without either his own mount or an explanation.

The Castle and the Hidden Purpose

Continuing over the mountain, Peredur reaches a castle in a valley beside a river. In its hall he finds a lame, grey-headed man and Gwalchmai. His stolen horse stands in the same stall as Gwalchmai's, and both men welcome him. A yellow-haired youth then kneels before Peredur and asks for his friendship. He reveals that he had taken the forms of the black maiden and the other figures who directed or confronted Peredur, including the one associated with the bloody head and lance. The head belonged to Peredur's cousin, killed by the Sorceresses of Gloucester; those same sorceresses had lamed his uncle. The youth identifies himself as that cousin and says a prediction requires Peredur to avenge these wrongs. This revelation changes the meaning of the trials without explaining every marvel as a straightforward test. The chessboard, the black man, the stag, and the elusive fighter have all carried Peredur closer to the family history concealed behind the earlier signs. The episode's ending turns discovery into action: Peredur and Gwalchmai take counsel and send for Arthur and his household to confront the sorceresses. The Castle of Wonders is thus not merely a place of strange spectacles; it is the point where Peredur's wandering encounters acquire a stated connection to kinship, prophecy, and revenge.
