Columba made Iona his centre of activity, but his labours were not confined to it. He travelled with his companions and preached the Gospel as far north as Inverness, where King Brude was converted. He also preached among the Southern Picts, and a church was built at Abernethy by King Gartnaidh, as an outcome of his mission and as a memorial of his labours. He was also a far-seeing statesman, and succeeded in reconciling the feuds of the Northern and Southern Picts, and in making the two kingdoms one. His life was spent in missionary activity and beneficent service, and he died at Iona. The day before his death he "ascended the hill that overlooketh the monastery, and stood for some little time on its summit, and as he stood there with both hands uplifted, he blessed his monastery, saying, 'Small and mean though this place is, yet it shall be held in great and unusual honour, not only by Scotic kings and people, but also by the rulers of foreign and barbarous nations, and by their subjects; the saints also, even of other churches, shall regard it with no common reverence.'" On the following day, at nocturnal vigils, he went into the church, and knelt down in prayer beside the altar, and "his attendant Diormit, who more slowly followed him, saw from a distance that the whole interior of the church was filled with a heavenly light in the direction of the saint," which, as he drew near, quickly disappeared. "Feeling his way in the darkness, as the brethren had not yet brought in the lights, he found the saint lying before the altar," and all the monks coming in, Columba moved his hand to give them his benediction, and died 9th June 597, while "the whole church resounded with loud lamentations of grief." He left behind him an imperishable memory in the hearts of the people converted by him to the Christian faith, and in the national church which he so splendidly helped to build up. He wrote an Altus, and is said to have copied 300 books with his own hand. He was buried at Iona.
