The Doom of the Griffiths

I have always been much interested by the traditions which are scattered up and down North Wales relating to Owen Glendower (Owain Glendwr is the national spelling of the name), and I fully enter into the feeling which makes the Welsh peasant still look upon him as the hero of his country. There was great joy among many of the inhabitants of the principality, when the subject of the Welsh prize poem at Oxford, some fifteen or sixteen years ago, was announced to be “Owain Glendwr.” It was the most proudly national subject that had been given for years.
Perhaps, some may not be aware that this redoubted chieftain is, even in the present days of enlightenment, as famous among his illiterate countrymen for his magical powers as for his patriotism. He says himself—or Shakespeare says it for him, which is much the same thing—
‘At my nativity The front of heaven was full of fiery shapes Of burning cressets . . . . . . . . I can call spirits from the vasty deep.’
And few among the lower orders in the principality would think of asking Hotspur’s irreverent question in reply.
Among other traditions preserved relative to this part of the Welsh hero’s character, is the old family prophecy which gives title to this tale. When Sir David Gam, “as black a traitor as if he had been born in Builth,” sought to murder Owen at Machynlleth, there was one with him whose name Glendwr little dreamed of having associated with his enemies. Rhys ap Gryfydd, his “old familiar friend,” his relation, his more than brother, had consented unto his blood. Sir David Gam might be forgiven, but one whom he had loved, and who had betrayed him, could never be forgiven. Glendwr was too deeply read in the human heart to kill him. No, he let him live on, the loathing and scorn of his compatriots, and the victim of bitter remorse. The mark of Cain was upon him.
But before he went forth—while he yet stood a prisoner, cowering beneath his conscience before Owain Glendwr—that chieftain passed a doom upon him and his race:
