He came to the mouth of Hell, which here, again, assumes the form of a demon’s wide-opened mouth, into which, each time he draws in his breath, swarms of souls are drawn in with it, to be again puffed out as he respires--an image already occurring in the Vision of Esdras before referred to. There, too, was the usual bridge, spanning a foul flood, wherein condemned spirits wallowed. At the far end of it was a crystal wall, and in it a gate of gold and jewels, which led to the Terrestrial Paradise, the halting-place of the spirits that were cleansed of sin, and awaiting their final perfection; while, to render this anticipation of Dante yet more striking, a multitude of these passed before Owen, chanting psalms. Two archbishops met him, and conducted him to the top of a mountain, whence he obtained a Pisgah view of the gate of Paradise, ‘like gold refining in a glowing furnace.’ Then, with a flash of fire from Heaven, the vision ended. Nothing certain is known concerning the origin of this legend, though it evidently existed long before Henry of Saltrey’s day. As we have seen, it was accounted for by a legend connecting it with the Apostle of Ireland; it is referred to by Joscelin, also a twelfth-century writer, in his _Life of St. Patrick_, but there is no mention of it in any of the earlier writings concerning that Saint. Indeed, some chroniclers refer it to one Patrick, a hermit of the neighbourhood, and this origin is given in the popular story of Fortunatus; and it is unlikely that popular tradition would have had recourse to some obscure and even hypothetical Saint, if the connection with the Apostle had been generally recognised. Probably, the island may have been the scene of some local pagan cult, taken over, with the necessary modifications, by the Christian community established there, in something the same manner as St. Brigid’s fire at Kildare. From the resemblance which the practices there observed bore to those connected with the Cave of Trophonius and the Eleusinian Mysteries, it seems not unlikely that if the origin of the rites could be traced, some analogies might be established between the ancient worship of Ireland, and some of the more obscure Greek cults. However this may be, the legend of St. Patrick’s Purgatory soon achieved an almost unexampled popularity, and was speedily adopted into the popular fictions of most European countries. Marie de France, in the early part of the thirteenth century, made it the subject of a long poem, and was closely followed by several Anglo-Norman writers, while it is recorded in the learned collections of Jean de Vitry, Vincent de Beauvais, and Caesar of Heisterbach, and by several of the leading chroniclers, such as Giraldus Cambrensis, Matthew Paris, and Froissart. Meanwhile, the island in Loch Derg became one of the recognised holy places to which pilgrims even from remote parts of Europe, such as Italy, Hungary, etc., resorted for the purpose of procuring the remission of past sins,
