[194a] The sound of the name, in connection with the word “hual,” in a former line, makes it very probable that the hero mentioned was of the tribe of Caswallon Law Hir, celebrated as one of the “hualogion deulu” of the Isle of Britain, called so because the men bound themselves together with the
“hualau,” or fetters of their horses, to sustain the attack of Serigi Wyddel, whom Caswallon slew with his own hand, when he drove the Irish out of Anglesey.
“Tri hualogion teulu Y. P. Teulu Caswallon Llawhir a ddodasant hualeu eu Meirch ar eu traed pob deu o naddynt wrth ymladd a Serigi Wyddel yng Cerrig y Gwyddyl y Mon, a theulu Rhiwallon mab Uryen yn ymladd ar Saeson, a theulu Belyn o Leyn yn ymladd ag Etwyn ym mryn Ceneu yn Rhos.” (Triad 49, first series.)
Caswallon Law Hir was the son of Einion Yrth ab Cunedda Wledig, king of Gododin. He succeeded to the sovereignty of North Wales, A.D. 443, and is said to have died in 517. There was a Cas son of Seidi, who was one of the heroes of Arthur’s Court.
