The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 86
Of Saint Olcanus, the Teacher and Bishop, raised out of the Earth.
A certain prince, going on a journey, heard, not without much amazement, a voice as if the voice of an infant weeping in a sepulchre, and, staying, he bade his people to open the sepulchre; and within he found a living boy nigh unto the dead mother. Him, by general advice, did the prince raise out of the chamber of death, and bear unto Saint Patrick, who, baptizing the child, named him Olcanus, for that he had suffered much evil, and in a fit season sent him to be instructed in letters. And he, being arrived at good stature, and being desirous of learning, went into Gaul; and having long abided there, and acquired much learning, he returned to his country; and being so returned, he instituted schools, and taught many scholars who in after-time were holy bishops. But this renowned teacher attained the episcopal dignity, and, at length closing his life in much sanctity, was illustrious even for many miracles.
