The remarkable thing is that a fifteenth-century writer should have recorded two facts which were as little known at the time when he wrote as they are to the generality of English readers to-day; the first, that in the days of St. Petrock a bishop might have been found occupying a cell, living as a monk or hermit, though not necessarily living alone; and the second, that there was in pre-Norman times a place bearing the name of Languihenoc, both of which are placed beyond dispute by the evidence given us in the chapter on Monastery-Bishoprics and by the testimony of Domesday Book. It surely requires an imagination of wider scope to believe that the writer was not transcribing or interpreting an authentic document than to accept the most fantastic legends of Celtic saints. The service rendered to research is twofold: it witnesses to the historicity of the Life even if it does not establish the reputation of its writer, and it adds one more to our list of Celtic bishops in the person of Guethnoc, who as Gwethnoc is honoured in Finistère and elsewhere in Brittany. At this point it seems convenient to summarise the results of our survey. It has been maintained that coincidence and resemblance have been invested with an importance disproportionate to their real value, that where coincidence has been claimed for the purpose of discrediting traditional doctrine it has often proved as illusory as the rainbow, that resemblance unsupported by other evidence has proved to be imaginary or superficial, that in the case of the Cornish saints, whose names have been supposed to resemble place-names, there is nothing to warrant the suspicion that they are eponymous, that the Lives of the Saints as they have come down to us must be estimated in the light of the mentality of the writers and readers of them, that, however ornate or barbaric they may be considered to be, when they record ordinary events the statements are worthy of investigation and often of historical value, and that a comparatively modern life of a saint may afford evidence of the substantial accuracy of the facts which it records.
