"Idleness is the enemy of the soul: hence brethren ought at certain seasons to occupy themselves with manual labour and again at certain hours with holy reading. Between Easter and the calends of October let them apply themselves to reading from the fourth hour until the sixth hour.... From the calends of October to the beginning of Lent let them apply themselves to reading until the second hour. During Lent let them apply themselves to reading from morning until the end of the third hour, and in these days of Lent let them receive a book apiece from the library and read it straight through. These books are to be given out at the beginning of Lent." The great importance of this rule arises from the fact that whilst monks were becoming very numerous, books were very few. Hence in order that the requisite number of copies might be available, writing had to be taught; in order that the monks might be able to read the books, it is conceivable that in some cases reading also would have to be taught. Moreover, the copying of manuscripts was considered to comply with the regulation as to manual labour prescribed by the Benedictine rules. Consequently wherever a Benedictine monastery came into existence, there books were multiplied, and a library gradually developed. As the years went on, the Benedictine labours in the intellectual world increased. Mabillon remarks, "Almost alone, the order of St. Benedict for several years, maintained and preserved letters in Europe. There were frequently no other masters in our monasteries, and frequently the cathedral schools drew theirs from the same source."[14] The purpose of this digression has been to show that by the time that the monks entered upon their mission in this country, the idea of monasticism was firmly established on the continent. The monastic houses consisted of communities of men or of women who, leaving the outer world behind them, dedicated their lives to the worship and the praise of God. They concentrated their attention upon the world to come, and, as far as possible, they endeavoured to anticipate it in the present stage of existence. Labour, either physical or mental, was one of their special obligations. Limiting ourselves to intellectual labour, we note that to some was entrusted the instruction of the children who were brought to them and of those members of the community who still needed education; to others was assigned work in the scriptorium; to others was allotted the task of giving instruction in singing and of making due preparation for the musical part of the monastic services; others, according to their capacity, continued their studies, and, by the chronicles which they wrote, enable posterity to reconstruct the history of their days.
