Twrch Trwyth- Celtic CreatureCreature · Monster

The Enchanted King

Twrch Trwyth was once a king whom God transformed into a boar for his wickedness. The tale in Culhwch ac Olwen does not elaborate on the nature of his sins, but the punishment left him monstrous: a great boar of supernatural size and ferocity, accompanied by seven young pigs that were themselves transformed warriors. Between his ears he carried three treasures — a comb, shears, and a razor — that were needed to groom the beard of the giant Ysbaddaden, father of Olwen, as one of the impossible tasks set for the hero Culhwch before he could win the giant's daughter in marriage.

Arthur himself had attempted to negotiate with the boar. He sent Gwrhyr, his interpreter of languages, to speak with Twrch Trwyth, but the beast refused to yield the treasures, saying he had been shamed enough by his transformation and would give nothing willingly. The boar's ability to speak, and his awareness of his former kingship, makes the subsequent hunt not merely a chase but a war against a conscious, defiant intelligence (Culhwch ac Olwen).

The Great Hunt

The hunt is the longest sustained episode in Culhwch ac Olwen and reads as an itinerary of destruction across three countries. Arthur first pursued Twrch Trwyth through Ireland, where the boar and his companions devastated a fifth of the island, killing warriors and hounds alike. Arthur's forces drove the boar into the sea, and he made landfall in Wales at Porth Clais in Dyfed.

Across south Wales the hunt raged, from Preseli to the valleys of the Tywi and the Llwchwr. At each engagement Arthur lost men of renown. Individual combats between named warriors and the boar's piglet-companions are recorded with the specificity of a battle chronicle: this warrior killed that pig at this ford; that warrior was slain in return. The comb was seized at one encounter, the shears at another, each retrieval costing lives.

The final confrontation took place in Cornwall. Arthur's remaining forces cornered Twrch Trwyth and seized the razor from between his ears. The boar, stripped of his last treasure, was driven into the sea and never seen again. The text does not say he was killed — only that he disappeared into the water, leaving the hunt's survivors to carry the three grooming implements back to Ysbaddaden (Culhwch ac Olwen).

The earlier reference in the Historia Brittonum names the boar as Porcus Troit and mentions Arthur's hunt in passing, confirming that the tradition predates the full narrative in Culhwch ac Olwen (Historia Brittonum, ch. 73).
