Rhydderch figures in traditional tales, and there are references to him in the Merlin poems ( Black Book of Carmarthen , 49. 16, 50. 3, 52. 11, 56. 16, 57. 16). He is also referred to as the victor in the battle of Arfderydd , which was fought, according to Harl. MS. 3859 ( Cymm. , ix, 155) in 573 . In the triads he is named as one of the ‘ three liberal ones of the Island of Britain ’ ( Myv. Arch. , 389), his court is said to have been devastated by Aidan , king of the Scots , 574-606 (ibid., 391), and ‘ Drudlwyd ’ is given as the name of his steed ( Black Book of Carmarthen , 28. 5). According to the Black Book of Carmarthen , 64. 8-9, he was buried at Aber-erch ; but this must be a late saga tradition.
