A well-known tale concerns Rhitta Gawr, a giant who held court in Snowdonia. He marched against warring kings Nyniaw and Peibaw, overwhelmed their armies and took their beards as trophies of his victory and fashioned them into a cap for himself. The twenty-six kings of Britain assembled their armies to destroy Rhitta but were vanquished by the giant, who cut off the kings' beards and fashioned a great cape out of them to protect him from the cold. Sometime later, as Arthur "washed his hands after slaying the red-eyed giant of Cernyw", he received a message from Rhitta, demanding his beard to patch his cloak. Arthur refused, and Rhitta marched south with his armies to claim it from him. In the resulting confrontation, Rhitta is forced to shear his own beard, and retreats "much humbled in stature but much wiser in knowledge". A variant tale claims that after receiving the demands, Arthur marched furiously up to Snowdonia and fought against the giant in a duel, in which he "lifted up his sword and struck Rhitta on the crown of the head a blow so fiercely-wounding, severely-venomous and sternly-smiting that it cut through all his head armour and his skin and his flesh and clove him in twain.", According to the story, Arthur commands that a cairn be built over his body which forms Gwyddfa Rhudda. Over the intervening centuries the name of Rhudda was forgotten and Gwyddfa Rhudda became known as Yr Wyddfa.
, the giant of Castell Maelor, was captured in Cyfeilog, about twelve miles from his own castle and was sentenced to death. His enemies allowed him his final request to blow on his horn three times before his death. The first time he blew, his hair and beard fell out, and on the second blast of his horn, so great was the strength and force of the sounding that all his finger and toe-nails fell off completely. On the third blast of his horn the intensity of the force of the sound caused the horn to be broken into small pieces. Maelor's son, Cornippin, who was hunting with his horse and his hound, heard the sound of his father's hand and lamented over his suffering. He made to rescue his father and in riding with such haste and swiftness, he tore the head of his hound off its body. He spurred his horse onwards, leaped in one great bound over the Ystwyth river and attacked his father's captors. In the ensuing battle, Cornippin was slain.
Cribwr Gawr
Cribwr the Giant lived in Castell Cefn Cribwr in Morgannwg. His three sisters were all killed by Arthur through "treachery". Arthur succeeded in slaying the giantesses by nicknaming himself as "Hot Pottage" to the first sister, and "Warm Porridge" to the second sister and as "a morsel of bread" to the third, and when the first sister called for help against Hot Pottage Cribwr answered: Wench, let him cool; and in the same manner he answered the second sister, when she sought assistance against Warm Porridge. And the third sister called out that the Morsel of Bread was choking her; and to this he answered, Wench, take a smaller piece. And when Cribwr reproached Arthur for killing his sisters Arthur replied: Cribwr take thy combs And cease with currish anger If I get a real chance—surely What they have had, thou shalt have too.
Other notable giants
The Historia Brittonum claims that Benlli Gawr was an early king of Powys, who was burned to death after acting aggressively towards Germanus of Auxerre. Canthrig Bwt, a giantess and witch notorious in the folklore of Gwynedd, lived under a great stone in Nant Peris and killed and ate a number of the community's children. Gogfran the Giant is recorded in the Welsh Triads as the father ofGwenhwyfar, Arthur's third wife. A tale tells of the imprisonment of a number of his sons by the giants of Bron Wrgan, leading to Arthur's attack on the abode to free his brothers-in-law.
