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. Then the servants of Fortunatus began to exhibit anger, and to insist on their master being restored to them. The abbot was frightened, and sent for an old man who had once penetrated far into the cave with a ball of twine, the end attached to the door-handle. This man volunteered to seek Fortunatus, and providentially his search was successful. After this the abbot refused permission to any one to visit 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.... In English there are two versions. In one of these, 'Owayne Miles,' the origin of the purgatory is thus described:--
"Holy byschoppes some tyme ther were,
That tawgte me of Goddes lore.
In Irlonde preched Seyn Patryke;
In that londe was non hym lyke:
He prechede Goddes worde full wyde,
And tolde men what shullde betyde.
Fyrste he preched of Heven blysse,
Who ever go thyder may ryght nowgt mysse:
Sethen he preched of Hell pyne,
Howe we them ys that cometh therinne:
And then he preched of purgatory,
As he fonde in hisstory;
But yet the folke of the contré
Beleved not that hit mygth be;
And seyed, but gyf hit were so,
That eny non myth hymself go,
And se alle that, and come ageyn,
Then wolde they beleve fayn."
Vexed at the obstinacy of his hearers, St. Patrick besought the Almighty to make the truth manifest to the unbelievers; whereupon
"God spakke to Saynt Patryke tho
By nam, and badde hym with Hym go:
He ladde hym ynte a wyldernesse,
Wher was no reste more no lesse,
And shewed that he might se
Inte the erthe a pryvé entré:
Hit was yn a depe dyches ende.
'What mon,' He sayde, 'that wylle hereyn wende,
And dwelle theryn a day and a nyght,
And hold his byleve and ryght,
And come ageyn that he ne dwelle,
Mony a mervayle he may of telle.
And alle tho that doth thys pylgrymage,
I shalle hem graunt for her wage,
Whether he be sqwyer or knave,
Other purgatorye shalle he non have.'"
Thereupon St. Patrick, "he ne stynte ner day ne night," till he had built there a "fayr abbey," and stocked it with pious canons. Then he made a door to the cave, and locked the door, and gave the key to the keeping of the prior. The Knight Owain, who had served under King Stephen, had lived a life of violence and dissolution; but filled with repentance, he sought by way of penance St. Patrick's Purgatory. Fifteen days he spent in preliminary devotions and alms-deeds, and then he heard mass, was washed with holy water, received the Holy Sacrament, and followed the sacred relics in procession, whilst the priests sang for him the Litany, "as lowde as they mygth crye." Then Sir Owain was locked in the cave, and he groped his way onward in darkness, till he reached a glimmering light; this brightened, and he came out into an underground land, where was a great hall and cloister, in which were men with shaven heads and white garments. These men informed the knight how he was to protect himself against the assaults of evil spirits. After having received this instruction, he heard "grete dynn," and
"Then come ther develes on every syde,
Wykked gostes, I wote, fro Helle,
So mony that no tonge mygte telle:
They fylled the hows yn two rowes;
Some grenned on hym and some mad mowes."
He then visits the different places of torment. In one, the souls are nailed to the ground with glowing hot brazen nails; in another they are fastened to the soil by their hair, and are bitten by fiery reptiles. In another, again, they are hung over fires by those members which had sinned, whilst others are roasted on spits. In one place were pits in which were molten metals. In these pits were men and women, some up to their chins, others to their breasts, others to their hams. The knight was pushed by the devils into one of these pits and was dreadfully scalded, but he cried to the Savior and escaped. Then he visited a lake where souls were tormented with great cold; and a river of pitch, which he crossed on a frail and narrow bridge. Beyond this bridge was a wall of glass, in which opened a beautiful gate, which conducted into Paradise. This place so delighted him that he would fain have remained in it had he been suffered, but he was bidden return to earth and finish there his penitence. He was put into a shorter and pleasanter way back to the cave than that by which he had come; and the prior found the knight next morning at the door, waiting to be let out, and full of his adventures. He afterwards went on a pilgrimage to the Holy Land, and ended his life in piety....
Froissart tells us of a conversation he had with one Sir William Lisle, who had been in the Purgatory. "I asked him of what sort was the cave that is in Ireland, called St. Patrick's Purgatory, and if that were true which was related of it. He replied that there certainly was such a cave, for he and another English knight had been there whilst the king was at Dublin, and said that they entered the cave, and were shut in as the sun set, and that they remained there all night and left it next morning at sunrise. And then I asked if he had seen the strange sights and visions spoken of. Then he said that when he and his companion had passed the gate of the Purgatory of St. Patrick, that they had descended as though into a cellar, and that a hot vapor rose towards them and so affected their heads that they were obliged to sit down on the stone steps. And after sitting there awhile they felt heavy with sleep, and so fell asleep, and slept all night. Then I asked if they knew where they were in their sleep, and what sort of dreams they had had; he answered that they had been oppressed with many fancies and wonderful dreams, different from those they were accustomed to in their chambers; and in the morning when they went out, in a short while they had clean forgotten their dreams and visions; wherefore he concluded that the whole matter was fancy."
The next to give us an account of his descent into St. Patrick's Purgatory is William Staunton of Durham, who went down into the cave on the Friday next after the feast of Holyrood, in the year 1409.
