This they all did; and in the fight which followed, Oswald gained a complete victory, and Cadwallon was slain. The place of Oswald’s victory was called ‘Heavenfield’; and, says Bede, ‘many people to-day take chips and shavings from the wood of that holy cross and put them in water, and sprinkle the water on sick men and beasts, or give them it to drink, and they are at once cured.’ * * * * * With the accession of King Oswald Christianity returned to the people of the north. This time, however, it was brought not by the monks of Rome, but by British monks from a monastery which had been established by Columba, an Irish saint, on the tiny island of Iona, lying off the west coast of Scotland. It was to this monastery that Oswald sent asking for teachers for his people. In reply there was sent him a monk of hard and stern nature, to whom the people would not gladly listen; so that he was able to effect little, but returned to Iona and reported that he could do nothing because the people of Northumbria were unteachable. ‘Was it not, brother,’ said one of his fellow monks, ‘you who were not sufficiently patient and gentle with those untaught men?’ The question made all present turn to the speaker, and they quickly decided that he was worthy to be sent as teacher to their friend, King Oswald. So came to Northumbria the saintly Aidan, whose success in converting the heathen Angles was due chiefly to the fact that as he taught so he himself lived. For, says Bede, he in no way desired or sought after the things that are of this world; but all the worldly goods that were given him by kings or by rich men he gladly gave to the poor and needy who came to him. Through all the land he travelled, visiting towns and wayside villages, and never on horseback, unless there were special need, but always on foot. And wheresoever he came and whomsoever he met, whether rich or poor, he turned to them. If they were unbelievers, then he invited them to believe in Christ; if they were believers he strengthened them in their belief, and with word and deed stirred them up to almsgiving and the performance of good deeds. By the labours of Aidan and his fellow monks the men of the north again became Christians; and such earnest Christians were they that they hallowed with the ‘Sign of the Cross’ the places at which they held their meetings for the purposes of government.
