Another poem, "Gwaith Argoed Llwyfain", refers to another campaign against the Angles of Bernicia. It also provides remarkable insights. Here, the leader of the Angles is named as Fflamddwyn – perhaps meaning "flamebearer" or "flamboyant one." It may refer to Theodoric of Bernicia (r. ca. 584-591) whose reign coincides with Urien's. The idea that it refers to Ida, the first king of Bernicia (r. 547-559), is probably too early to correspond to Urien and Owain's dates (although there is some crossover with the earliest dates of Urien's reign).
