The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 150

A wicked Tyrant is transformed into a Fox.

In that part of Britain which is now called Vallia, lived a certain tyrant named Cereticus; and he was a deceiver, an oppressor, a blasphemer of the name of the Lord, a persecutor and a cruel destroyer of Christians. And Patrick hearing of his brutal tyranny, labored to recall him into the path of salvation, writing unto him a monitory epistle, for his conversion from so great vices. But he, that more wicked he might become from day to day, laughed to scorn the monition of the saint, and waxed stronger in his sins, in his crimes, in his falsehoods and in his cruelties. The which when Patrick heard, taught by the Divine Spirit, he knew that the vessel of evil was hardened in reprobation, prepared in no wise for correction, but rather for perdition; and thus he prayed unto the Lord: "O Lord God, as thou knowest this vulpine man to be monstrous in vice, do thou in a monstrous mode cast him forth from the face of the earth, and appoint an end unto his offences!" Then the Lord, inclining his ear unto the voice of his servant, while on a certain time the tyrant stood in the middle of his court surrounded by many of his people, suddenly transformed him into a fox; and he, flying from their sight, never more appeared on the earth. And this no one can reasonably disbelieve, who hath read of the wife of Lot who was changed into a pillar of salt, or the history of the King Nabuchodonoser.
