Louis IX. took the ground that it was better to transcribe books than to purchase the originals, because in this way the mass of books available for the community was increased. Louis was, however, speaking only of religious literature; he could not believe that the world would be benefited by any distribution of the works of profane writers. Ziegelbauer is in accord with Montalembert and others in giving to the Benedictines of Iceland the credit for the collections made of the Eddas and for the preservation of the principal traditions of the Scandinavian mythology. He also confirms the conclusion arrived at by the Catholic historians generally, that the literary monuments of Greece and Rome which escaped the devastation of the barbarians were saved by the monks and by them alone. He cites, as a few examples from the long list of classics that were thus preserved, five books of the _Annals_ of Tacitus, found at Corbie; the treatise of Lactantius on the _Death of Persecutors_, preserved at Moissac; the _Auluraria_ of Plautus, and the _Commentaries_ of Servius on Virgil, preserved in Fleury; the _Republic_ of Cicero, found in the library of Fleury in the tenth century, etc.[83] In confirmation of the statement that the classics were by no means neglected by the earlier monastery collectors, Montalembert cites Alcuin, who enumerated among the books in his library at York the works of Aristotle, Cicero, Pliny, Virgil, Statius, Lucan, and Trogus Pompeïus. A further reference to this library will be found in the chapter on the Monastery Schools. In Alcuin’s correspondence with Charlemagne, he quotes Ovid, Horace, Terence, and Cicero, and acknowledges that in his youth he had been more moved by the tears of Dido than by the Psalms of David.[84] Loup de Ferrières speaks of having borrowed from his friends the treatise _De Oratore_ of Cicero, a _Commentary on Terence_, the works of Quintilian, Sallust, and Suetonius. He says further that he was occupying himself in correcting the text of the oration of Cicero against Verres, and that of Macrobius.[85] Abbot Didier of Monte Cassino, who later became Pope, succeeding Gregory VII., had transcripts made by his monks of the works of Horace and Seneca, of several treatises of Cicero, and of the _Fasti_ of Ovid.[86] S. Anselm, Abbot of Bec in the time of Gregory VII., recommends to his pupils the careful study of Virgil and of other profane writers, “omitting the licentious passages.” _Exceptis his in quibus aliqua turpitudo sonat._[87] It is not clear what method the abbot proposed to have pursued in regard to the selection of the passages to be eliminated. It is hardly probable that at this time there had been prepared, either for the use of the monks or of any other readers, anything in the form of expurgated editions. S. Peter Damian seems to have expressed the true mind of an important group at least of the churchmen of his time, when he referred to the study of pagan writers.
