The Battle of Arthuret
Robert Vaughan
VNČ; Panton 51, 116r.-116v.

It chanced that the shepherds of Rhydderch and Aeddan aforesaied, by the instigation of the Devil, fell out for no other cause than a lark's nest; who, having beaten one another to the efussion of their blood, at last acquainted their lords of the whole strife, and they presently engaged themselves in the quarrel, entering into open hostility with such eagerness and hatred that having mustered their forces and committed some outrages, they appointed a day and place to try the matter by dint of sword; and Aeddan fearign to be too weak to encounter Rhydderch, drew to his side Gwenddoleu the son of Ceidiaw fo the tribe of Coel Godeboc, a very powerful prince, and they, joining their forces, met Rhydderch at a place called Arderydd, where upon the first encounter Gwenddoleu was slain, and with him Llywelyn, Gwgawn, Einiawn, and Rhiwallawn, the sons of Morfryn, Merlin caledonius's bretheren; and in the end after a great slaughter on both sides, Rhydderch obtained the victory, and Aeddan fled the country.
