ON another occasion, when this eminent man was staying in the Hinba island (Eilean-na-Naoimh), he saw, on a certain night, in a mental ecstasy, an angel sent to him from heaven, and holding in his hand a book of glass, regarding the appointment of kings. Having received the book from the hand of the angel, the venerable man, at his command, began to read it; and when he was reluctant to appoint Aidan king, as the book directed, because he had a greater affection for Iogenan his brother, the angel, suddenly stretching forth his hand, struck the saint with a scourge, the livid marks of which remained in his side all the days of his life. And he added these words: ‘Know for certain,’ said he, ‘that I am sent to thee by God with the book of glass, that in accordance with the words thou hast read therein, thou mayest inaugurate Aidan into the kingdom; but if thou refuse to obey this command, I will strike thee again.’ When therefore this angel of the Lord had appeared for three successive nights, having the same book of glass in his hand, and had repeated the same commands of the Lord regarding the appointment of the same king, the saint, in obedience to the command of the Lord, sailed across to the Iouan island (Hy, now Iona), and there ordained, as he had been commanded, Aidan to be king, who had arrived at the same time as the saint. During the words of consecration, the saint declared the future regarding the children, grandchildren and great- grandchildren of Aidan, and laying his hand upon his head, he consecrated and blessed him. Cummene the Fair, in the book which he wrote on the virtues of St. Columba, states that St. Columba commenced his predictions regarding Aidan and his children and kingdom in the following manner: ‘Believe me, unhesitatingly, O Aidan,’ said he, ‘none of thine enemies shall be able to resist thee, unless thou first act unjustly towards me and my successors. Wherefore direct thou thy children to commend to their children, their grandchildren, and their posterity, not to let the sceptre pass out of their hands through evil counsels. For at whatever time they turn against me or my relatives who are in Hibernia, the scourge which I suffered on thy account from the angel shall bring great disgrace upon them by the hand of God, and the hearts of men shall be turned away from them, and their foes shall be greatly strengthened against them.’ Now this prophecy hath been fulfilled in our own times in the battle of Roth (Magh Rath, fought 637), in which Domnall Brecc, the grandson of Aidan, ravaged without the slightest provocation the territory of Domnall, the grandson of Ainmuire. And from that day to this they have been trodden down by strangers-a fate which pierces the heart with sighs and grief.
