Overview
Twrch Trwyth is pursued for the comb, razor and scissors carried between his ears, necessary to prepare Ysbaddaden for Culhwch's marriage to Olwen. Before the main hunt, Menw takes bird form and approaches the Irish lair to check the implements. He obtains only a bristle, while venom shaken from the angry boar leaves him permanently unwell. Arthur later arrives with a vast host and finds Twrch with seven young pigs. Irish attacks and Arthur's household both fail; Arthur himself fights for nine days and nights without killing even one pig. Asked about their leader, he says a former king was transformed by God for his sins. That explanation is Arthur's statement within the narrative. Another bird-shaped envoy, Gwrhyr, requests negotiation, but the young boar Grugyn refuses and announces an attack on Arthur's country. Grugyn's glittering silver-wire bristles belong to him, not automatically to his father.
The company crosses to Wales, where the pursuit moves through named places and accumulates named deaths. At Cwm Kerwyn, Twrch kills several champions and Arthur's son Gwydre, and is himself wounded. Later losses include men, dogs and royal relatives; his young pigs gradually fall or separate from him. At the Severn, the hunters force Twrch into the water. Mabon son of Modron snatches the razor from horseback, and Kyledyr Wyllt takes the scissors from the opposite side. Recovering the comb requires further pursuit into Cornwall, where earlier hardships are described as slight by comparison. The last implement is finally obtained, but the boar is driven into the deep sea and his destination remains unknown. Arthur then returns to rest and anoint himself. The sequence ends with successful retrieval and an unresolved surviving monster, rather than a simple slaying. Its geographical route, specialised helpers and human costs are essential to the episode's scale.
Origins & earliest records
The selected witness is Culhwch and Olwen within the medieval Welsh Mabinogion manuscript tradition, read through Charlotte Guest's translation originally published during 1838–1849. The National Library of Wales identifies the tale among the early surviving copies in the White Book of Rhydderch. Surviving transcription and later translation dates do not determine the narrative's first oral composition.
Records & interpretation
The sustained hunt, named participants, carried implements and explanation of transformation are literary evidence for an exceptional individual boar. The silver-wire bristles belong specifically to Grugyn, one of his young, and are not transferred to their father here. The account is neither a record of an ordinary wild-boar hunt nor evidence of human biological transformation.

Read the open encyclopedia overview
Twrch Trwyth (Welsh pronunciation: [tuːɾχ tɾʊɨθ] ; also Welsh: Trwyd) is a fabulous wild boar in Arthurian legend. A richly elaborate account of its hunt is described in the Welsh prose romance Culhwch and Olwen, which was probably written around 1100.
Its hunt involved King Arthur and his hosts and his hound Cafall, and was also deemed to require other recruited men of talent, other hounds, and additional equipment such as a leash, according to the tasks (anoetheu) prescribed by the giant Ysbaddaden, though events did not always unfold as the giant foretold. The boar was brought out of Ireland, driven to Britain, and finally shoved off a cliff into the sea at Cornwall.
The legend, in simpler form, dates much earlier, since Arthur's use of his hound Cavall (Latin: Cavall (base text, MS. MS. H), Latin: caball (MS. K), Latin: caballusMS. D1), Latin: caballus(MSS. D2 G) to hunt the boar (Latin: Troynt (base text, MSS.H K), Troit (MSS.C1 D G Q); or Terit (MSS. C2 L)) is glimpsed in a piece of geographical onomasticon composed in Latin in the ninth century, the Historia Brittonum.
A passing reference in the elegy Gwarchan Cynfelyn (7th century), preserved in the Book of Aneirin, is reckoned to be its earliest mention in literature. Trwyth is also mentioned in several other pieces of poetry from the Middle Welsh period.
The name in Welsh can be construed to mean "the boar Trwyth", and past scholars argued it may be analogous to the boar Triath of Irish mythology (see #Etymology and Irish cognate below).
