The apostolic labors of St. Columba were not confined to the territories of the Picts and Western Islanders, he superintended also the ecclesiastical affairs of the British Scots, and formed some religious establishments in their kingdom; one of them, near Loch-Awe in Argyle, was governed by one of his monks named Cailten, of whom it is related, that he died at Hy, the parent-house, if we may so call it. The holy abbot Columba, foreseeing that the death of this monk was nigh, sent for him that he might give him his blessing, as being in some sort necessary to his terminating his course in the true spirit of monastic obedience. In traversing the southern part of this kingdom, our saint visited St. Kentigern, bishop of Glasgow, and spent with him a few days. Nor is it improbable that he visited South Britain, then possessed by the Anglo-Saxons, for there were Christians of that nation in Hy before his death, converted in all probability by himself or his disciples. Meantime, he did not neglect to watch vigilantly over his other monasteries, not only in Scotland and the Isles, but also those which he had founded in his own dear and more cherished land. Thither did he often send messengers on business connected with his monasteries, or with other pious objects. On one occasion he dispatched to Clogher, in all haste, Lugaid Laithir, one of his monks, (whom Adamnan calls his legate by excellence,) with a box containing a benediction, which, when dipped in water, was to cure the saintly virgin Mangina, whose limb was broken at her returning from the holy mysteries; which it did most effectually instantly on its application. [2] St. Columba was frequently visited by persons from Ireland, who were either his former friends, or who wished to become so, or who desired to receive his advice on various matters; and these, with all other strangers, he received with the greatest kindness, and treated most hospitably. Besides the holy men already mentioned, Columbanus, bishop in the province of Leinster, [3] came to see him. The holy abbot conceived a great friendship for this prelate, so that, being apprized of his death by revelation, he gave orders in the morning that the monks who were preparing for their respective occupations should refrain from work on that day; and when all was ready for the holy mysteries, the whole community, clothed in white garments as on a Sunday or other solemnity, proceeded to the church along with the saint. When the choir had come to a part of the service in which the name of St. Martin used to be commemorated, the saintly abbot cried out, "To-day you must sing for the holy bishop Columbanus;" and thus they became informed of his death.
