The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 33
Of the Evil-doer Swallowed up by the Earth.
And in that church the holy prelate stood before the altar on a certain day, celebrating the divine mysteries, when an evil-doer, a bondsman of Satan, thrusting with accursed boldness a rod through the window, overturned the chalice, and sacrilegiously poured out on the altar the holy sacrifice. But the Lord instantly and terribly avenged this fearful wickedness, and in a new and unheard-of manner destroyed the impious man. For suddenly the earth, opening her mouth (as formerly on Dathan and Abiron), swallowed up this magician, and he descended alive into hell. And the earth, thus disjoined and rent asunder, closed on him again; but to this day a ditch yet remaining declareth the judgment of the divine wrath. But the holy sacrificer, being struck with sorrow, mourned with heavy mourning over the chalice that had been filled; and the chalice, with the divine sacrifice entire therein, stood erect before him, being raised by the divine Power, nor did any trace of the offering remain to be seen.
