The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 61
How another Magician is Sunken up to the Ears, and again is Raised up.
And the deadly end of this evil-doer being discerned by one who was germane unto him in his flesh and in his mind, and who was not able to succor his brother when perishing, therefore sought he to avenge his destruction on Patrick as his destroyer; and being enraged against the saint, he sought to put him to death. But the Lord fought for Patrick, and the earth in like manner opened and swallowed up the magician, even to his ears. Then the man, being almost swallowed up in the earth, implored pardon of the saint, and promised that he would believe in Christ, and that he would obey his doctrine. And the saint, being moved with pity, prayed for him unto the Lord; and immediately the earth cast him forth, and raised him. And the unmerciful man, being mercifully saved, gave thanks unto the power that had saved him, and believed in Christ, and received the grace of baptism. Thus doth the Lord, distinguishing between the light and darkness, severely condemn the reprobate and obstinate in evil, and mercifully saveth those who fly unto his mercy.
