‘Cynedyr the Wild’
Kynedyr Wyllt
One of Arthur’s warriors and son of Hetwn Silver Brow.
As one of his tasks, Culhwch had to obtain Cynedyr’s help in hunting the boar Twrch Trwyth. Cynedyr was identified by Ysbaddaden to be the only man in the world who could hold the leashes of the pups, Aned and Aethlem.
He is nine times wilder than the wildest beast on the mountain.
In Celtic literature the wild man motif is popular.
