If, however, that part of the legend which introduces Servanus must be rejected, the remainder derives some support from the old Welsh documents. In the Triads of Arthur and his Warriors, which are undoubtedly old, the first is termed ‘Three tribe thrones of the island of Prydain;’ and the third of the tribe thrones is ‘Arthur, the chief lord at Penrionyd in the north, and Cyndeyrn Garthwys, the chief bishop, and Garthmwl Guledic, the chief elder.’[361] The chronology of the life of Kentigern is not inconsistent with that which here connects him with the historic Arthur, and the epithet Guledic, which was applied to the chief among the Cymric kings of the north, gives us Garthmwl as the name of the king of the district in which Glasgow was situated. In the _Bonedd y Seint ynys Prydain_, or Pedigrees of the Saints of Britain, we find the following pedigree: ‘Kyndeyrn Garthwys, son of Ywein, son of Urien Reged, son of Cynfarch, son of Meirchiawngul, son of Grwst Ledlwm, son of Cenau, son of Coel; and Dwynwen, daughter of Ladden Lueddog of the city of Edwin (_Ddinas Edwin_, or Edinburgh), in the north, was his mother.’[362] We have seen that prior to this period Monenna had founded a church on the summit of Dunpelder, in which she established nuns;[363] and it is possible that Dwynwen or Taneu may have been one of these nuns, who, by the violation of her religious vow, had incurred the sentence of being exposed in a curach in the adjacent firth. There is nothing impossible in a small boat being driven before an east wind as far as Culross; and certain it is that on the shore where she is said to have landed there was a small chapel dedicated to Kentigern.[364] We learn from the narrative that there had been an earlier church at Glasgow founded by Ninian, which Kentigern may have restored, and he makes his appearance in the martyrologies in the ninth century as ‘Saint Kentigern, Bishop of Glasgow and Confessor.’[365] [Sidenote: Kentigern driven to Wales.]
