In the thirteenth century, Matthew Paris compiled his chronicles, the writing in which appears to have been, for the greater part at least, done by his own hand, but at this time, in a large proportion of the literary work carried on in the English monasteries, the transcribing was done by paid scribes. This, however, was much less the case in the Continental monasteries. In Corbie, towards the latter half of the century, there is a record of zealous writing on the part of a certain Brother Nevelo. Nevelo tells us that he had a penance to work off for a grave sin, and that he was allowed to do this by work in the _scriptorium_.[106] During this century, the monasteries of the Carthusians were particularly active in their literary work, but this work was limited almost entirely to theological and religious undertakings. An exception is presented in the chronicles of the Frisian monk Emo. While Emo was still a school-boy, he gave the hours which his companions employed in play, to mastering penmanship and the art of illuminating. Later, he was, with his brother Addo, a student in the schools in Paris, Orleans, and Oxford, and while in these schools, in addition to their work as students, they gave long hours of labour, extending sometimes through the entire night, to the transcribing of chronicles and to the preparation of copies of the so-called heathen literature. Emo was the first abbot of the monastery in Wittewierum (1204-1237), and it is recorded that the abbot, while his brothers were sleeping, devoted his nights to the writing and illuminating of the choir books. In this monastery, Emo succeeded in bringing together in the _armarium librorum_ an important collection of manuscripts, and he took pains himself to give instructions to the monks in their work as scribes. The quaint monastic record entitled the _Customs of Clugni_ was written by Ulrich, a monk of Clugni, some time between the years 1077 and 1093 at the request or under the instructions of William, Abbot of Hirschau. This was the Abbot William extolled by Trithemius as having restored the Order of S. Benedict, which had almost fallen into ruin in Germany. Trithemius speaks of his having founded eight monasteries and restored more than one hundred, and says that next to the reformation wrought by the foundation and influence of Clugni, the work done by Abbot William was the most important recorded in the annals of his Order.
