Oswald had grown to manhood in Dal Riada. His faith had been formed by the monks of Iona and it was deep and profound. In his Ecclesiastical History, Bede portrays Oswald as his ideal of kingship, a warrior saint equivalent to Plato’s philosopher king. Modern historians tend to discount this as hagiography but in part this is the result of the restricted modern idea of what it means to be holy: a plaster idol of piety, partaking of equal measures of Victorian sanctimoniousness and modern self-help psychobabble. This is about as far from real holiness as it is possible to get. Holiness is both far more terrible and far more practical than either: it will reduce a man to the state of a shivering child and enable him to endure pains and trials beyond enduring.

I suspect that Oswald really was as Bede portrayed him: a warrior and a saint. A man who could leave his enemies coughing their lifeblood into the mud but who would also break up the silver plates upon which he was eating to give to the poor clustered around his gate, a man who prayed so habitually that his hands, in rest, assumed the gesture of prayer that he had learned on Iona.
