Addanc
MabinogionAddanc is a cave-dwelling monster whose hidden position and poisonous darts sustain a daily cycle of death and restoration among the sons of the King of the Tortures. Its defeat by Peredur depends not on strength alone but on a special stone that reverses the creature’s advantage: Peredur can see it while it cannot see him. The encounter ends the attacks and becomes the basis of a pledge the Empress later recalls.
Identity and Threat
Addanc is identified as the creature that kills the sons of the King of the Tortures once every day. The Black Oppressor describes the monster’s location as a cave and gives Peredur a route through a sequence of destinations that leads to it. The account makes Addanc’s threat more than a single encounter: the victims are killed repeatedly, and the danger remains in place for anyone who approaches the cave without understanding how the creature attacks.
The Black Oppressor also explains that Addanc’s position makes it difficult to confront. A stone pillar stands at the cave entrance; Addanc can see those who enter, while they cannot see it. From behind the pillar, it strikes with a poisonous dart. The cave is therefore not merely the monster’s lair but part of its method: its hidden vantage turns entry into exposure and conceals the attacker from its intended victims.
The Repeating Deaths
At the palace of the King of the Tortures, Peredur sees the consequences of Addanc’s attacks before encountering the creature. A charger arrives carrying a corpse, which one of the women removes and treats with warm water and precious balsam. The dead man rises alive and greets Peredur; two more men arrive in the same manner and are restored as well. The women’s repeated care makes visible the strange pattern behind the household’s apparent survival: Addanc kills its victims daily, but they are brought back to life.
The youths ride out the next morning, intending to face the danger again. They refuse Peredur’s request to accompany them, warning that if he is killed there will be no one to restore him. He follows after them nonetheless. This exchange establishes an important difference between the youths and their visitor: their repeated deaths belong to a cycle with a means of return, whereas Peredur would face the same danger without that protection.
The Stone and the Cave
Before reaching the cave, Peredur meets a maiden who knows his quest and warns him that Addanc will kill him by craft rather than courage. She explains the pillar’s role and offers a stone that will let him see the hidden monster without being seen. In return, she asks Peredur to pledge that he will love her above all women; he gives his pledge, and she places the stone in his hand before vanishing. Her warning supplies the knowledge Peredur needs, while the stone directly counters the creature’s advantage.
Peredur reaches a valley marked by contrasting sights: white sheep cross the river and become black when black sheep bleat, while a tree is green on one half and aflame on the other. A youth there offers him the choice of visiting a palace, watching a hunt, or taking the narrower road toward Addanc’s cave. Peredur chooses the cave. He carries the stone in his left hand and his lance in his right, sees Addanc as he enters, pierces it, and cuts off its head. The attack succeeds because the stone has changed the terms of the encounter: Addanc’s concealment no longer protects it from Peredur.
Defeat and Aftermath
After Peredur emerges, the three companions are waiting at the cave entrance. They tell him that a prediction had foretold his slaying of the monster, and he gives them Addanc’s head. They offer him a choice among their three sisters in marriage and half their kingdom. Peredur does not present the killing as a search for wealth or marriage, though he says that, if he were to take a wife, he would prefer their sister above others. The cave’s threat has been overcome, and the victory brings an offer of reward, but Peredur’s stated purpose is not simply possession of that reward.
The stone’s significance continues beyond the killing. In a later episode, the Empress reminds Peredur of the pledge he made when she gave him the stone and he killed Addanc; she then entertains him for fourteen years. The tale thus makes the monster’s defeat consequential in two connected ways: it ends the daily danger to the King of the Tortures’ sons, and it binds Peredur’s adventure to an obligation that outlasts the cave encounter.
Narrative Role
Addanc functions as a hidden adversary whose apparent invulnerability rests on unequal knowledge. The Black Oppressor provides a route and a description of the cave’s danger; the maiden supplies the means to overcome it; Peredur applies that knowledge at the decisive moment. The sequence gives the monster a concrete tactical advantage rather than making the victory a contest of strength alone.
The repeated restorations of the victims also set this episode apart from an ordinary rescue. The youths face death again each day, and the household’s restoration rituals keep that pattern in view until Peredur breaks it by killing Addanc. The monster’s defeat therefore resolves a recurring threat while advancing Peredur’s larger journey: a promised stone makes the victory possible, and the pledge attached to that gift remains active after the danger is gone.
