Arderydd, is the name of a place somewhere in Scotland; perhaps, Atterith, about six miles from Solway Frith. This battle is mentioned in the Triads, and was fought by Gwenddolau ap Ceidiaw and Aeddan Fradawg, petty princes of the North, against Rhydderch Hael, king of Cumbria, who got the battle. Myrddin Wyllt, or Merlin, the Caledonian, was severely handled by Rhydderch Hael, for siding with Gwenddolau, his patron, which he complains of in his poem entitled Afallenau, or Apple-trees.
