The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 38
Of the Hostages of Dichu which were Freed by an Angel.
Leogaire, a man of leonine fierceness, with a high and swelling heart, rose above himself in the pride of his exploits, for that he seemed to himself to hold the land by the strength of his arm and the firmness of his valor. And he took hostages of all the provincial chiefs bordering on his kingdom, and among others he held in his power the sons of Dichu, lest any of them should raise the head to defend themselves, or the heel to offend him. For he, being rooted in the errors of idolatry, strenuously favored the magicians and the soothsayers; and his neck was stiff and his head was stubborn against the true religion. But when he understood that Dichu, with all his household and kindred and people, had turned unto Christ, and renounced the gods of their country, even the devils, his mind and his eye were inflamed with the fury of his wrath. Therefore, being moved in his mind, he gave order that the hostages of Dichu should be punished in a manner mainly destructive; for he forbade drink to be given to them, to the end that they might perish of thirst. And the Spirit revealed this unto the saint, and he disclosed it unto Dichu, and advised him to seek from Leogaire the respite of at least ten days until Patrick should appear before him. Yet could he not, as directed by the man of God, obtain the respite even of one day, but rather did his entreaties more vehemently blow up the flame, and exasperate the heart of the king with the fire of fiercer rage, which when the prelate heard he betook himself to his accustomed arms of prayer; and behold, on the following night an angel appeared and gave unto them to drink, and satisfied their thirst. And from that hour not any suffering of thirst came on them; and when a few days had passed, at the prayers of the saint, the angel again appeared, and freed them from their prison-house and from the power of their enemies. And from the place wherein they were confined he bore them through the air, as was formerly the prophet; and he left one of them in a place in Down, where is now erected the church of Saint Patrick, and the other on a neighboring hill surrounded by a marsh of the sea; and he broke asunder the chains wherewith they were bound, and each place is even to this day, from the broken chains, called Dun-daleathglas.
