The Abbot Erpo's Abbey: Kloosterrade's First Moment of Glory

After the death of Abbot Richer in 1122, a period of administrative tension and internal strife began at Kloosterrade. The canons were unable to elect a superior from among their own ranks due to disagreements. This was likely due to the lack of strong candidates for the position of abbot, or perhaps the eagerness with which one or another presented himself as the new superior was perceived as a threat to solidarity. On four occasions, clerics from outside the abbey were elected as superiors. However, all of these elections were always controversial and proved disappointing on several occasions. Conflicts arising from disagreements over the interpretation of the monastic rule or from attempts to adapt monastic customs to stricter rules led to superiors being removed from office by the bishop or the pope, or to their choosing to leave the abbey of their own accord. In 1134, Borno was elected superior for the second time. He had been elected ten years earlier and wanted to introduce choral prayer at that time. This attempt met with fierce resistance, and the pope decided to maintain the old customs. Borno then had no choice but to leave Kloosterrade. Upon his return, the internal dissensions subsided. The decision made by the choir masters in 1137, following Borno’s death, was significant and of great importance for the internal consolidation of the monastic community. From then on, they would select only superiors from within their own community, preferably brothers who had been educated at the abbey school and raised in monastic discipline from childhood.

With Erpo, who was born in Maastricht, Kloosterrade was led in 1141 by an abbot who had been educated at the abbey from childhood. His long abbacy lasted at least until 1178 and served as a stabilizing force. It is not without reason that historiography describes this period as the golden age of medieval Kloosterrade. For decades, economic prosperity, piety, scholarship, and spirituality prevailed. The Consuetudines, the precepts and customs introduced from the Rottenbuch by Abbot Richer and subsequently modeled on the example of the Springiersbach monastery, took their final form, concluding the evolution toward a convent with a moderate ordo novus as its precept. In some respects, Erpo left his mark on a stricter observance of the monastic rule. By eliminating the use of fat in all foods, he implemented the dietary austerity for which Abbot Richer—who had prohibited the consumption of meat—had set the tone. Furthermore, he introduced the silentium, a period of silence, by imposing a strict prohibition on the choir members speaking outside of the times set aside for choral prayer services. On the other hand, Erpo believed that the celebration of the hours “per diem et noctem,” during which choral prayer services lasted almost without interruption from midnight to midnight, was too demanding for the canons. In addition to the stricter rules of monastic life he imposed, he therefore simplified the overloaded liturgical schedule. He limited daily choral prayers to the hours proper and eliminated supplements such as the separate Marian office and the singing of the 15 psalms before Matins and the seven penitential psalms before Prime. With these adjustments to the observance of the precepts and the arrangement of choral prayer, the development of Kloosterrade under Abbot Erpo reached its zenith. Thus, after only half a century, the abbey reached its zenith: Kloosterrade was the first community between the Rhine and the Scheldt to live according to the new directives of the Rule of St. Augustine, and, due to the uniqueness of its Consuetudines, it enjoyed supraregional prestige. For the other Augustinian monasteries that were continuing their reform, Kloosterrade served as a model.

A defining feature of Kloosterrade Abbey in the 12th century and the first half of the 13th century was its status as a double monastery. With the arrival of Minister Embrico, his wife Adeleida, and their children Heriman and Margareta, a community of nuns settled next to the men’s monastery. This development did not align with the views of the founder, Ailbertus. In 1140, the superior, Johan, succeeded in finding housing for the nuns outside the walls of Kloosterrade. Abbot Erpo readmitted the women; he found a compelling reason for his decision in the necessity for the nuns to perform all manner of domestic tasks. Over the following decades, however, the influx of monks was much greater than anticipated, and the problem of an undesirable mixed community arose once again. It was not until 1243, with the transfer of the nuns to the monastery at Sinnich, newly founded by Abbot Marsilius, that the status of a double monastery came to an end.

The exercise of pastoral ministry was just as undesirable and incompatible with the ideal of an ascetic and contemplative monastic life, which had been the abbey’s original aspiration. Abbot Erpo’s predecessor, Superior Johan, broke with this attitude in 1140 when he decided to exercise a parish ministry and accepted the ministry of the church in Kerkrade through the abbey’s choir masters. Toward the end of Erpo’s abbacy, Kloosterrade acquired the rights of patronage over several parish churches. The abbey’s sphere of influence thus expanded significantly between the Meuse and the Rhine.

The monastic chronicle, compiled around 1160 during Erpo’s abbacy, is a tangible testament to the abbey’s heyday. The medieval manuscript, which bears neither a title nor an inscription, was written by three unknown chroniclers and belongs to the genre of *narrationes fundationis*. It recounts the story of the founding of a monastery, the life of its founder, and often its subsequent history. These chronicles were written with great care and attention in the scriptorium of the abbey or monastery, often by anonymous monks of the second generation. The Annales Rodenses recount the life of Ailbertus, his education and training in Tournai, as well as his search for a place where he could live as a hermit. The chronicle then traces the history of the abbey’s first five decades, from Ailbertus’s arrival in 1104 until the final entry of the year 1157. The manuscript, known asthe Annales Rodenses, owes its name to the chapel master Nicolaas Heyendal, who wrote a sequel to the history of Kloosterrade toward the end of the seventeenth century. The importance of the Kloosterrade chronicle for historiography is demonstrated by the fact that data relating to the period after 1157 are very scarce. The other sources that allow us to trace the ins and outs and the fortunes of the abbey in the late Middle Ages are limited to a few preserved charters.

Abbot Erpo also succeeded in enhancing Kloosterrade’s material prestige. No fewer than 16 charters dating from 1141 to 1177 attest to this, recording donations and purchases of land as well as the acquisition of rights to revenues. By the end of Erpo’s tenure, likely in 1178, the abbey’s estate had reached an area of 3,570 hectares. Although nearly half of this area was due to donations or the entry of monks, more than one-fifth of the land was purchased by Abbot Erpo. This increase in area reflects the abbey’s prosperity at that time. After 1178, the growth of land holdings stagnated; the abbey’s income then consisted mainly of rents and fines. During the period of decline that followed the War of the Limburg Succession and later, especially in the 16th century, the abbey was forced to sell a considerable portion of its estate out of financial necessity and to fund the costs of repairing damage to the church and monastery buildings caused by wars and looting.

The date of Abbot Erpo’s death is unknown. His successor, Abbot Rutger, is first mentioned as abbot of Kloosterrade in 1186. He later served as a witness to Duke Henry III of Limburg’s donation to Floreffe Abbey, as evidenced by the charter confirming the donation.
