The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 143
Of Saint Kertennus, the Bishop of Clochor.
And Kertennus, a disciple of Saint Patrick, bore the saint, now worn with age, on his shoulders, for so necessity required; and by his panting showed he his weakness or weariness. And the saint said unto him, "Often hast thou carried me, yet never before have I perceived thee thus to pant." Then answered Kertennus, "Wonder not, holy father, for now hath mine age come on me, and my companions whose years are as mine have from the forecast of thy bounty received the refreshment of a little rest; and mine head is covered with gray hairs, and I labor with daily toil, and earnestly do I long for quiet, which above all things else I need." Therefore Saint Patrick compassionating Kertennus, promised unto him a place fitted for contemplation, yet not unsuited to the exercise of pious duties. And as he much desired the presence of so worthy a disciple, he provided for him a church; yet not too remote from the archiepiscopal seat, which at the angel's command he had builded in Ardmachia; nor yet too near, lest by succeeding archbishops he should be oppressed; thus was it done, that in his frequent visits to Saint Patrick the man of God should not by the distance be wearied, nor his church appear contemptible by too close a neighborhood. And after some days he placed him over the church of Clochor, which the saint himself then ruled; and when he had thereto consecrated him, he gave unto him a chrismatory, which he had received from heaven. And Saint Kertennus there dwelling, and exercising within doors the office of an abbot, and abroad the office of a bishop, cherished his gray hairs, and finished his life in holiness.
