Pair Dadeni- Celtic ArtifactArtifact"Cauldron of Rebirth"

Origins and the Gift to Ireland

The Pair Dadeni first appears in the Second Branch of the Mabinogi as a possession of Brân the Blessed, king of the Island of the Mighty (Britain). Its origin is given in a tale within a tale: Brân explains that the cauldron came from Ireland, where a giant man and woman had emerged from a lake carrying it. The Irish king Matholwch found them troublesome and tried to destroy them by locking them in an iron house and heating it white-hot, but they burst through the walls and escaped to Britain, bringing the cauldron with them to Brân.

When Matholwch came to Britain to marry Brân's sister Branwen, Efnysien — Brân's malicious half-brother — mutilated the Irish king's horses as an insult. To compensate for the outrage, Brân gave Matholwch several gifts, chief among them the Pair Dadeni: a cauldron that could restore dead warriors to life. The restored men were whole in body but returned without the power of speech. The gift was meant to heal a breach, but it armed the Irish with a weapon that would be turned against the British in the war to come (Branwen ferch Llŷr, Second Branch of the Mabinogi).

The War and the Sacrifice

When Brân crossed the sea to rescue Branwen from mistreatment in Ireland, the resulting battle became a slaughter that the cauldron prolonged beyond all natural limits. Each time the British cut down an Irish warrior, the body was thrown into the Pair Dadeni and emerged alive, mute but able to fight again. The British were being ground down against an enemy that could not stay dead.

Efnysien, whose insult had started the entire chain of events, performed the act that ended both the cauldron and himself. He lay down among the Irish corpses and was thrown into the cauldron with them. Once inside, he stretched himself out with all his strength until the cauldron burst into four pieces, and his own heart burst with it. The destruction of the Pair Dadeni was Efnysien's single redemptive act — the man whose malice had caused the war destroyed the weapon that was winning it, at the cost of his life (Branwen ferch Llŷr, Second Branch of the Mabinogi).

The cauldron's destruction did not save the British. Of the entire host that crossed to Ireland, only seven men survived to return. Brân himself was mortally wounded and ordered his head severed and carried back to Britain. The Pair Dadeni's legacy was total loss on both sides: Ireland was depopulated, Britain was emptied of its warriors, and the gift meant to restore peace had instead fueled the most devastating war in the cycle.
