Owain ab Urien Rheged

   Owain appears to have greatly distinguished himself in the struggle against the rise of Northumbria, both before and subsequently to the death of his father, but with what ultimate success we are not acquainted.
   There exists an ancient Poem, printed among those of Taliesin, called the Elegy of Owain ap Urien. It commences:
"The soul of Owain ap Urien
May its Lord consider its exigencies,-
Reged's chief the green turf covers."
   We have the following Triad relating to him:
"Three Knights of battle were in the Court of Arthur; Cadwr, the Earl of Cornwall; Lancelot du Lac; and Owain the son of Urien Rheged. And this was their characteristic, that they would not retreat from battle, neither for Spear, nor for Arrow, nor for Sword, and Arthur never had shame in battle, the day he saw their faces there, and they were called the Knights of Battle."
   Owain is also mentioned with Rhun mab Maelgwn, and Rhufawn befr mab Deorath Wledig, as one of the Three blessed Kings; and in the 52nd Triad, we are informed that his Mother's name was Modron, the daughter of Afallach, and that he was born a twin with his sister Merwydd, or Morvyth, to whom Cynon ap Clydno's attachment is well known.
   His grave is mentioned in the Graves of the Warriors.
"The grave of Owain ap Urien is of quadrangular form,
Under the turf of Llan Morvael."
   In her notes, Lady Guest informs us that frequent allusions were made to Owain by the Bards of the Middle Ages, especially by Lewis Glyn Cothi, who in an ode to Gruffudd ap Nicholas, a powerful chieftain of Carmarthenshire, and one of the descendants of Urien Rheged, has, among other things, the following passage:
"Gruffudd will give three ravens of one hue,
And a white lion to Owain."
   The Editor of the works of Glyn Cothi supposes that "this expression may allude to Griffith presenting his son with a shield, with his own arms emblazoned upon it, and the royal lion for a crest." Lady Guest stated that "the three ravens undoubtedly apply to the armorial bearings of Urien Rheged, which are still borne by his descendants of the House of Dynevor; the lion also may have been an heraldic bearing of the family, but I am inclined to think that the Bard here intended an allusion to one of the principal incidents of the Lady of the Fountain. That he was acquainted with this Tale is evident, from some lines occurring in one of his Poems, addressed to Thomas ap Philip of Picton Castle, in which Owain and Luned are mentioned together."
