The Mabinogion summary

The story in one page

Across eleven fragmented tales, the landscape of medieval Wales transforms into a stage for the supernatural and the chivalric. Heroes like Pwyll swap identities with lords of the underworld, while the giant Bendigeid Vran leads a disastrous invasion of Ireland to avenge his sister Branwen. The stories transition from raw Celtic myth — where men are turned into animals as punishment — to the courtly knightly adventures of Arthur’s companions. Whether Peredur is hunting invisible monsters or a magical cauldron is bringing dead warriors back to life, the narrative remains grounded in the specific geography of Britain and the complex social debts of its kings.
