The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 73
Foylge is punished with a double Death, and the deceiving Fiend is driven out of his body.
And in Lagenia was a certain wicked idolater named Foylge, who was an eminent adversary of Christ, so far forth as he was able; this child of Belial frequently sought occasion to lay on Patrick, the anointed of the Lord, his impious hands, for to him it was very grievous not only to see but even to hear the saint. To this inveterate malice was he urged, for that the man of God had destroyed the aforementioned idol Ceancroythi, unto the abominable worship whereof he was especially bound. But when he could not effect his wicked purpose, he one day attacked the charioteer of Saint Patrick, who was named Odranus; for he seized him sitting in the chariot, and strangled him, so that by the one act of blood his fury might be the more fiercely excited toward another. And the saint, wounded in his heart, cast the weapon of his malediction on this child of hell, who, pierced thereby, even at the moment breathed out his soul into the infernal regions. Of some it is said that Odranus, foreknowing the servant of Satan to be intent on the death of the saint, obtained that in his stead he might on that day hold the reins. And this he did, earnestly desiring to lay down his life for the saint, lest, so bright a lamp being extinguished, the people of Ireland should again walk in darkness. And the saint beheld his soul borne into heaven by the angels, and placed in the seat of the martyrs. But the old enemy, entering the dead body, showed to all a false and feigned Foylge, as if revived unto life, and dwelled therein as returned to his possessions and to his people. And after some days, as Patrick was passing nigh unto the dead man's dwelling, he called unto him certain of the family, and asked where Foylge was; and they answered that he was then within in the house, when the saint replied: "The soul of Foylge, for that he unjustly slew my chariot-driver, God justly judging and vindicating my cause, hath gone cut of his body, and descended into hell; but Satan, to the delusion and the seduction of mankind, hath entered into his corpse, and occupieth it as his own proper vessel." Then the saint forbade Satan that in that vessel he should longer abide, or deceive mankind with so wicked a phantom. And forthwith, at the command of the man of God, the deceiving spirit quitted his habitation of clay; the which, covered with worms, and raising horror and offence to all, was carried into instant sepulture. Nor let it be wondered that the devil should show himself in the visible form of his accustomed instrument, the God permitting whose judgments are an abyss; but rather let Him be feared who can destroy both body and soul in hell.
