Note 190e — THE GODODIN.
John Williams translation
There were two territories of this name, Argoed Derwennydd, (Derwent wood apparently) and Argoed Calchvynydd, “between the river Tren and the river Tain, that is the river of London.” (Iolo MSS. p. 476.) One of them, the former probably, was the patrimony of Llywarch Hen.
