Tegan Eurvron, one of the three exalted ladies of the court of Arthur, was the wife of Caradoc of the brawny arm; and bore the fame of pre-eminence in chastity and other amiable virtues; thus was she appropriately associated in the Triad, with the highly extolled Enid.  Among the comments on the "Boy and the Mantle" her claim to further notice is incidentally brought forward.  Warton imagines that strange tale to be taken from an old French piece, entitled "Le Court Mantel;" "but," adds Bishop Percy, from whose "Reliques of Ancient English Poetry" we transplant this story, "after all it is most likely that all the old stories concerning king Arthur are originally of British growth, and that what the French and other southern nations have of this kind, were at first exported from this island."  The Rev. Evan Evans, editor of "Specimens of Welsh Poetry," confirms this opinion.  He says the story of the "Boy and the Mantle" is taken for what is related in some of the old Welsh manuscripts of Tegan Eurvron, a lady of king Arthur's court; she is said to have possessed a mantle that would not fit any incontinent woman: this, which the old writers say was reckoned among the curiosities of Britain, is often alluded to by the old Welsh bards.
