Note 140
As I am a stranger to the Welsh bards, Myrdhin, Llomarch, and Taliessin, my faith in the existence and exploits of Arthur principally rests on the simple and circumstantial testimony of Nennius (Hist. Brit. c. 62, 63, p. 114). Mr. Whitaker (Hist. of Manchester, vol. ii. p. 31-71) has framed an interesting, and even probable, narrative of the wars of Arthur: though it is impossible to allow the reality of the round table.
