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: “I doom thee to live, because I know thou wilt pray for death. Thou shalt live on beyond the natural term of the life of man, the scorn of all good men. The very children shall point to thee with hissing tongue, and say, ‘There goes one who would have shed a brother’s blood!’ For I loved thee more than a brother, oh Rhys ap Gryfydd! Thou shalt live on to see all of thy house, except the weakling in arms, perish by the sword. Thy race shall be accursed. Each generation shall see their lands melt away like snow; yea their wealth shall vanish, though they may labour night and day to heap up gold. And when nine generations have passed from the face of the earth, thy blood shall no longer flow in the veins of any human being. In those days the last male of thy race shall avenge me. The son shall slay the father.” Such was the traditionary account of Owain Glendwr’s speech to his once-trusted friend. And it was declared that the doom had been fulfilled in all things; that live in as miserly a manner as they would, the Griffiths never were wealthy and prosperous—indeed that their worldly stock diminished without any visible cause.
