If one were to quote from Adamnan's three Books of the Prophecies, Miracles, and Visions of Columba, there would be another book. Amid much that is childlike, and a little that is childish, what store of spiritual beauty and living symbol in these three books--the Book of Prophetic Revelations, the Book of Miracles of Power, the Book of Angelic Visitations. But there, as elsewhere, one must bear in remembrance that, in spiritual sight, there is symbolic vision as well as actual vision. When Colum saw his friend Columbanus (who, unknown to any on Iona, had set out in his frail coracle from the Isle of Rathlin) tossed in the surges of Corryvrechan; or when, nigh Glen Urquhart, he hurried forward to minister to an old dying Pict "who had lived well by the light of nature," and whose house, condition, and end had been suddenly revealed to him: then we have actual vision. When Aithnê, his mother, dreamed that an angel showed her a garment of so surpassing a loveliness that it was as though woven of flowers and rainbows, and then threw it on high, till its folds expanded and covered every mountain-top from the brows of Connaught to the feet of the Danish sea, and so revealed to her what manner of son she bore within her womb; or when, in the hour of Colum's death, the aged son of Tailchan beheld the whole expanse of air flooded with the blaze of angels' wings, which trembled with their songs: then we have symbolic vision. And sometimes we have that which partakes of each, as when (as Adamnan tells us in his third book) Colum saw angels standing upon the rocks on the opposite side of the Sound which divides Iona from the Ross of Mull, calling to his soul to cross to them, yet, as they assembled and beckoned, mysteriously and suddenly restrained, for his hour was not come.
