"D. Dionysii Carthusiani liber utilissimus de quatuor hominis novissimis, etc.," Parisiis, 1551. The account "De Purgatorio Sancti Patritii" extends from fol. 235 to fol. 237. "Enrique Saltarense" is Henry of Saltrey, a Benedictine monk of the Abbey of Saltrey in Huntingdonshire, who about the middle of the twelfth century first reduced to writing the Adventures of Owain, or Enius, in the Purgatory of St. Patrick. Of him Messingham writes thus. Referring to his authorities, he says:-- "What you shall find under the letter B, is taken from Henry Salteriensis, an English monk of the Cistercian order, who had been taught most excellent Precepts of a good Life as well as good Letters by Florentianus, an Irish bishop, and Gilbert de Luda [Louth, in Lincolnshire], Abbot of the Cistercian Monks, who also, being himself well instructed, used to teach others the fear of the Lord as the beginning of wisdom. . . . . And hence it is that he wrote unto Henry Abbot of Sartis one Book of the Purgatory of St. Patrick and one Book of the Pains of Purgatory. He flourished in the year of Grace 1140." -- "A Brief History of St. Patrick's Purgatory". Paris, 1718. Preface. "Cesario," which carelessness or the exigency of metre has separated from the "Esturbaquense," of the next line is Caesarius of Heisterbach, a well-known hagiological writer of whom Adrien Baillet thus speaks:-- "Un religieux Allemand de l'ordre de Citeaux nomme 'Cesaire de Heisterbach', qui mourut du tems de l'empereur Frederic II. travailla aussi a la vie des Saints." He adds in a note:-- "Cesaire se fit moine l'an 1198, au Val de Saint de Pierre, dit autrement Heisterbach, pres de la ville de Bonne, dans le diocese de Cologne, et ne mourut que pres de quarante ans apres. Il avoit ete maitre des novices dans son couvent, et ensuite prieur de la maison de Villiers." -- 'Discours sur l'histoire de la Vie des Saints. Les Vies Des Saints'. Paris, 1739. T. i., p. xlvii. "Mateo Rodulfo," printed as the names of one author in Calderon, separate into two persons in Messingham and Montalvan. The first is the well-known Mathew Paris, whose 'Relation of the vision of Owen the Irish Soldier' is expressly referred to in these words by Messingham, who also alludes to him more fully in his preface. 'What you shall find under the letter C,' says Messingham, 'is borrowed from Mathew Paris, an English Benedictine Monk, who had from his youth consecrated himself to a Monastic life, and polish'd most excellent talents of nature with exquisite Arts and Sciences, and adorn'd the same with all Christian virtues; being an Handicraft, a Writer, a good Painter, a fine Poet, an acute Logician, a solid Divine; and (which is much more valuable) pure in his Manners, bright in the innocence of his life, simple and candid. Pitseus, upon the year 1259, in which the said Mathew died, gives him a great many more encomiums, which for brevity sake I hear omit.'
