Next day early, Fortunatus received the Blessed Sacrament with his trusty Leopold; the door of the Purgatory was unlocked, each was provided with a taper, and then with the blessing of the abbot they were left in total darkness, and the door bolted behind them. Both wandered on in the cave, hearing faintly the chanting of the monks in the church, till the sound died away. They traversed several passages, lost their way, their candles burned out, and they sat down in despair on the ground, a prey to hunger, thirst, and fear. The monks waited in the church hour after hour; and the visitors of the Purgatory had not returned. Day declined, vespers were sung, and still there was no sign of the two who in the morning had passed from the church into the cave.

In the reign of Henry II. lived Henry of Saltrey, who wrote a history of the visit of a Knight Owen to the Purgatory of St. Patrick, which gained immense popularity, ... was soon translated into other languages, and spread the fable through mediaeval Europe....

Vexed at the obstinacy of his hearers, St. Patrick besought the Almighty to make the truth manifest to the unbelievers; whereupon
