The letters of Gerbert, Abbot of Bobbio (who, in 998, became Pope under the name of Sylvester II.), throw some light upon the literary interests of that famous monastery and of the time. He writes (about 984) to a monk named Rainald (letter 130 of the collection): “You know with what zeal I seek for copies of books from all quarters, and you know how many scribes there are everywhere in Italy, both in the cities and in the rural districts, I entreat you then ... that you will have transcripts made for me of M. Manilius’ _De Astrologia_, Victorinus’ _De Rhetorica_, and of the _Ophthalmicus_ of Demosthenes.... Whatever you lay out I will repay you to the full, according to your accounts.” In letter 123, Gerbert writes to Thietmar of Mayence for a portion of one of the works of Boëthius, his copy being defective. In letter 9, written to Abbot Giselbert, he asks for assistance in making good certain deficiencies in his manuscript of the oration of Cicero, _Pro Rege Deiotaro_. In letter 8, to the Archbishop of Rheims, he requests that prelate to borrow for him from Abbot Azo a copy of Cæsar’s _Commentaries_. In return he offers the loan of eight volumes of Boëthius. In letter 7, he requests his friend Airard to attend to the correction of the manuscript of Pliny, and to preparing transcripts of two other manuscripts. In letter 44, to Egbert, Abbot of Tours, he states that he has been much occupied in collecting a library, and that he had for a long time been paying transcribers in Rome, in other parts of Italy, in Germany, and in Belgium, and in buying at great expense texts of important authors. He asks the Abbot to aid in doing similar work in France, and he gives a list (unfortunately lost) of the works for transcripts of which he is looking. He is ready to supply the parchment and to defray all the expenses of the work. In other letters he makes reference to his own writings on rhetoric, arithmetic, and spherical geometry. These letters, for the reference to which I am indebted to Maitland,[206] assuredly give the impression that even in the dark period of the tenth century, there was no little activity in certain ecclesiastical circles and monastic centres in the transcribing, collecting, and exchanging of books, and not merely of missals, breviaries, or monkish legends, but of literature recognised as classic.
