Ten years after the landing of St. Columba in Iona the great battle of _Ardderyd_, or Arthuret, was fought between the pagan and the Christian parties in Cumbria; and the same year which saw Aidan, who had taken part in it, inaugurated by St. Columba as independent king of Dalriada, likewise witnessed the establishment of another of the chiefs who fought in that battle, Rydderch Hael, or the Liberal, as Christian king of Strathclyde, and the restoration of a Christian Church to its Cumbrian population. As Columba was the founder of the Christian Church among the northern Picts, so Kentigern was the great agent in the revolution which again christianised Cumbria. We are not, however, so fortunate in the biographers of Kentigern as we are in those of Columba. While those of the latter lived when the memory of his words and acts was still fresh in the minds of his followers, Kentigern found no one to record the events of his life till upwards of five centuries had elapsed after his death. A fragment of the life which had been used by John of Fordun and a complete biography by Jocelyn of Furness are all we possess, but neither of them was compiled before the twelfth century.[355] [Sidenote: Oldest account of birth of Kentigern.] The older life, of which a fragment only remains, states that ‘a certain king Leudonus, a man half pagan, from whom the province over which he ruled in northern Britannia obtained the name of Leudonia, had a daughter under a stepmother, and the daughter’s name was Thaney.’ This girl, having become Christian, ‘meditated upon the virginal honour and maternal blessedness of the most holy Virgin Mary,’ and desired, like her, to bring forth one who would be for the honour and salvation of her nation in these northern parts. She ‘had a suitor, Ewen, the son of Erwegende, sprung from a most noble stock of the Britons,’ but she refused to marry him; upon which the king her father gave her the alternative of either marrying him or being handed over to the care of a swineherd, and she chose the latter. The swineherd was secretly a Christian, having been converted by Servanus, a disciple of Palladius, and respected her wishes. Her suitor Ewen, however, succeeded by a stratagem in violating her in a wood, and she became with child, upon which her father ordered her to be stoned according to the laws of the country; but as none of the officers presumed to cast stones at one of the royal family, she was taken to the top of a hill called Kepduf and precipitated from it; having made the sign of the cross, however, she came down to the foot of the mountain unhurt. The king then ordered her to be given over to the sea, saying, ‘If she be worthy of life, her God will free her from the peril of death, if He so will.’ They brought her, therefore, to the firth, which is about three miles from Kepduf, to the mouth of a river called Aberlessic, where she was put into a curach,
