A public conflict for a private purpose
Math rules Gwynedd under a peculiar condition: except during war, his feet must rest in a maiden's lap. Goewin performs that role. His nephew Gilfaethwy desires her, and Gwydion devises a way to remove Math from court. He will obtain the extraordinary pigs that Pryderi has received from Arawn, knowing that their loss can produce war.
Disguised as a bard, Gwydion wins Pryderi's confidence through storytelling. Pryderi cannot give away the animals before they multiply, but Gwydion proposes an exchange. He conjures splendid horses, hounds, and equipment, receives the pigs, and hurries away because his fabricated payment will last only a day. Courtesy and entertainment have become instruments of fraud.

The cost falls on others
Pryderi pursues the stolen animals with an army. While Math is away on campaign, the brothers return to his chamber, drive away the attendants, and force Goewin to remain. Her later account explicitly identifies their attack and refusal to respect her will. The tale does not present this as an ordinary courtship.
The conflict kills many people before Pryderi proposes that he and Gwydion settle it themselves. Gwydion defeats and kills him through both fighting and magic. The southern army withdraws in mourning. When Math returns, Goewin tells him what happened. He offers marriage and authority as compensation and summons the brothers to face the injuries they have caused.

Punishment in successive animal forms
Math transforms the brothers into deer, then wild swine, then wolves over three successive years. They live as the animals they resemble and return each year with offspring. Math takes the young, gives them human form where narrated, and has them baptized. At the end he restores the brothers and declares their punishment sufficient.
Animal transformation here is neither a decorative talent nor an invitation to freedom. It makes privileged men subject to embodied conditions they did not choose. The narrative then reintegrates them, without reviving Pryderi or undoing Goewin's suffering. Its mixture of enchantment, dynastic power, and baptism belongs to the medieval literary witness and resists being reduced to a surviving fragment of an exclusively pagan system.
