The importance of these communities was growing from the beginning to the end of the Middle Ages, having its peak during the XII-XIII centuries. The monasteries not only constituted as places destined to the prayer of those men and women who left everything to find everything; They were also places of social power, as they were run by members of the most powerful families in the kingdom, as well as economic due to the large amount of land that from each monastic community were put into operation. Finally, monasteries were also constituted as the major centers of culture of Christian Europe, since from its scriptorium a large number of documents about day to day were generated, in addition to the copy of religious books and classic authors. Without this huge work of copying, possibly these works would have been lost and would not have reached us.
