The history of Enio had, however, existed in manuscript for nearly three centuries and a half before the Polychronicon was printed; it had been written by Henry, the Monk of Salterey, in Huntingdonshire, from the account which he had received from Gilbert, a Cistercian monk of the Abbey of the Blessed Virgin Mary of Luden, or Louth, above mentioned. [1] Colgan, after collating this manuscript with two others on the same subject, which he had seen, printed it nearly in full in his "Trias." ... Matthew Paris had, however, before this, in his "History of England," under date 1153, given a full account of the adventures of OEnus in the Purgatory. ... Sir Walter Scott mentions, in his "Border Minstrelsy," that there is a curious Metrical Romance in the Advocates' Library of Edinburgh, called "The Legend of Sir Owain," relating his adventures in St. Patrick's Purgatory; he gives some stanzas from it, descriptive of the knight's passage of "The Brig o' Dread;" which, in the legend, is placed between Purgatory and Paradise. This poem is supposed to have been written early in the fourteenth century. [Footnote 1: Colgan's "Trias Thanmaturgæ," p. 281, Ware's "Annals of Ireland," A.D. 1497.] A second extract on the subject, taken from the Essay by Mr. Wright on the "Purgatory of St. Patrick," published in London in 1844, gives still further information with regard to it. "The mode," he says, "in which this legend was made public is thus told in the Latin narrative. Gervase (the founder and first Abbot of Louth, in Lincolnshire) sent his monk, Gilbert, to the king, then in Ireland, to obtain a grant to build a monastery there. Gilbert, on his arrival, complained to the king, Henry II., that he did not understand the language of the country. The king said to him,' I will give you an excellent interpreter,' and sent him the knight Owain, who remained with him during the time he was occupied in building the monastery, and repeated to him frequently the story of his adventures in Purgatory. Gilbert and his companions subsequently returned to England, and there he repeated the story, and some one said he thought it was all a dream, to which Gilbert answered: 'That there were some who believed that those who entered the Purgatory fell into a trance, and saw the vision in the spirit, but that the knight had denied this, and declared that the whole was seen and felt really in the body.' Both Gilbert, from whom Henry of Salterey received the story, and the bishop of the diocese, assured him that many perished in this Purgatory, and were never heard of afterwards." It is clear from the allusion to it in Cæsarius of Heisterbach, that already, at the beginning of the thirteenth century, St. Patrick's Purgatory had become famous throughout Europe. 'If any one doubt of Purgatory,' says this writer, 'let him go to Scotland (i. e., Ireland, to which this name was anciently given), and enter the Purgatory of St. Patrick, and his
