The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 45
Of the Poison mingled in the Wine.
But the King Leogaire, fermenting with the gall of wickedness and deceit, knowing and marvelling how often the saint had escaped his snares, turned himself to other inventions, and whom he could not slay with the sword he plotted to destroy with poison. Therefore, by the hand of a certain evil-doer named Lugaich Mael, he gave his cup unto Patrick, whereof, that servant of Satan mingling poison with the wine, did the saint drink. But the man of God, taking the cup and invoking the name of the Lord, bended it forward, and all that was deadly therein poured he into the hollow of his hand unmixed with the rest of the liquor; then making the sign of the cross, what remained he blessed, and, to the confusion of the poisoner and the admiration of all who sat around, drinking thereout, he received neither hurt nor damage.
