The literary journeys of Mabillon were followed by similar journeys on the part of Father Montfaucon and Edouard Martene, who were both, like Mabillon, members of the learned Benedictines of St. Maur. Mabillon’s journeys covered the period of the long wars following the revocation of the Edict of Nantes (in 1685), including the campaigns between France and England in the Low Countries. It was probably due to these campaigns that his researches did not include any of the monasteries of the lower Rhine, of Flanders, or of Brabant. Martene’s journeys continued during a term of six years, in which time he examined manuscripts in more than one hundred cathedrals and at least eight hundred abbeys. The materials collected were utilised first in the new edition of the _Gallia Christiana_, and later, in five folio volumes, comprising only matter previously unpublished, issued under the title _Thesaurus Novum Anecdotorum_. The account of the journey was printed under the title _Voyage Littéraire de Deux Religieux Benedictins_. In 1718, Martene and Montfaucon were again sent on their literary travels, and the later collections were issued in 1724 in nine folio volumes, under the title _Veterum Scriptorum et Monumentorum Historicorum, Dogmaticorum, Moralium, Amplissima Collectio_. I specify these works of the literary Benedictines because, although by their date they do not properly belong to my narrative, they form a very important authority for what is known of the literary history of the monasteries. In some of the monasteries which had in earlier times been famous as centres of literary activity, the libraries were found by Mabillon and Martene in a grievous condition of destitution and dilapidation. At Clugni, for instance, they describe the catalogue (itself six hundred years old), written on parchment-covered boards three feet and a half long and eighteen inches wide (_grandes tablettes qu’on ferme comme un livre_), containing some thousands of titles, but of the books there remained scarcely one hundred. Martene was told that the Huguenots had carried them off to Geneva. At Novantula, of all its former riches Mabillon found but two manuscripts; and at Beaupré, of the great collection of manuscripts there remained but two or three; while many other famous libraries were in similar condition. The destruction of so large a portion of the collection of manuscripts and of the earlier printed books was due to a variety of causes. During the ninth century, the ravages of the Danes and Normans brought desolation upon a long list of the monasteries throughout Europe which could most easily be reached from the coast. In the index to the third volume of Mabillon’s annals, is given a long list of the Benedictine monasteries pillaged or destroyed by the Normans. The record begins _Normanni, monasteria et eis incensa, eversa, direpta_. In many of these visitations the loss of books must have been considerable. When, for
