This remarkable Breviary remained in use for over two centuries, its two extensive revisions witnessing the Cistercian concern for liturgical correctness.  Leaves were removed, and replaced by new ones; passages were erased and rewritten.  The fifteenth-century scribe, the cantor of Herrenalb, Johannes Zürn, signed and dated his revisions.  Preserved in its fifteenth-century binding, the two sets of foliation (original and fourteenth-century), and a fifteenth-century system of references linking the calendar and the liturgical collects, are notable features.

Provenance

1. This thirteenth-century Cistercian Breviary from the monastery of Herrenalb in Southwestern Germany was revised twice to keep it up to date with current liturgical practice.  Actively used for more than two hundred years, its story is complex, but compelling.  The original book was copied c. 1260; early in the fourteenth century, probably c. 1320-1330, some leaves were removed, and replaced by new ones.  Analysis of the feasts included in the calendar and Sanctorale allow us to date these first two sections (discussed in detail below).  This process was repeated in the fifteenth century in 1491 by a third scribe, Johannes Zürn, who replaced numerous leaves, erased and re-copied some of the earlier sections, and signed and dated the final page, f. 279v, “Anno 1491 frater iohannes zürn de nyposheim” (In the year 1491, Brother John Zürn of Neibsheim).  All three scribes were careful to use the same general layout, and the overall result is remarkably harmonious. 

Brother John from Neibsheim bei Bretten was a Cistercian monk from Herrenalb.  His work is known in twelve manuscripts (Heinzer, 2001, p. 87, this manuscript no. 10, as Kat. Trübner, 1886, no. 55), including the famous illuminated Herrenalber Gebetbuch, Staatsbibliothek zu Berlin - Preußischer Kulturbesitz, Ms. theol. lat. qu. 9.  Most of what is known about him is from the colophon in this prayer book.  He was from Neibsheim, north of Karlsruhe in Baden Württemberg, and was probably was born c. 1430; in a list from Herrenalb dated 1497, he is listed as one of the oldest monks.  His oldest dated manuscript is from 1468, the most recent, 1499.  It seems likely that he died soon after 1499.  As cantor of Herrenalb, he was in charge of the liturgy (and the correct copying of liturgical books), and with the exception of the prayer book, all the books he copied, either entirely or in part, were Breviaries or Diurnals.

Herrenalb, a Cistercian House about thirty kilometers south of Karlsruhe in the Black Forest was founded in 1148 by Berthold, Count of Eberstein and his wife, Otha, by monks from the Cistercian Abbey of Neuburg in Alsace (in the line of Morimond).  It was suppressed during the Reformation in 1536. It did not itself have any daughter houses, but it did have a close relationship with the nuns at Licthtenthal in the later Middle Ages from c. 1490-1523.  The monks from Herrenalb actively supervised the liturgy at Licthenthal, as part of the reform of that convent (Heinzer, 2001).  Many of the manuscripts copied by John Zürn in fact survived because they were preserved at Lichtenthal.  Heinzer has identified twenty-two (and possibly two additional manuscripts) surviving manuscripts from Herrenalb, the majority surviving from Lichtenthal’s library, and preserved today at the Abbey of Lichtenthal or at the Badische Landesbibliothek in Karlsruhe.

The Divine Office (today known as the Liturgy of the Hours) was the daily prayer of the Church, recited (or chanted) by priests, and other religious, including monks and nuns, beginning with Matins, said during the night, and continuing through the day, with Lauds at dawn, followed by Prime, Terce, Sext, None, Vespers, and concluding with Compline.  The regular observance of the Office was particularly important to monastic life.  The prayers and readings for the Office are included in a Breviary.  This is a monastic Breviary, which includes twelve lessons at Matins for major feasts. 

The manuscript is undoubtedly Cistercian, as evidenced by its liturgical use; the calendar includes many characteristic Cistercian Saints (Bernard of Claivaux, and his octave, Robert of Molesme, founder and first abbot of Cȋteaux (here “Ruperti”), Malachy, whose cult originated at Clairvaux, Peter, abbot of Tamié and later bishop of Tarentaise, and Edmund of Abingdon, archbishop of Canterbury, buried at Pontigny, as well as the Cistercian feasts for honoring the dead of their order (Commemoratio episcoporum et abbatum (January 11), Commemoration of the departed brothers, families and benefactors of the order, added (September 19) Commemoration of our parents, added (November 20).  The Cistercian system of punctuation that includes the mark known as the punctus flexus is found here in the first text (ff. 1rv); this text and the Canticles, ff. 263-267v, have also been accented to aid in reading out load (the accents and perhaps some of the punctuation may be added).

One of the characteristics of the Cistercian Order was their concern with establishing uniform customs and liturgical practices throughout the Order, and establishing a regular system to ensure this through annual general councils and visitations.  This manuscript as it survives today is a composite volume.  Two later scribes, one in the fourteenth century, and one in 1491, inserted new leaves to update the original thirteenth-century Breviary.  All three scribes were careful to use the same general layout, and the overall result is remarkably harmonious.  Nonetheless, the fifteenth-century leaves are easily identified because they are copied on thicker and rougher parchment (they are also generally cleaner).  The Sanctorale was originally foliated in red Roman numerals; in the fourteenth century, the second scribe numbered his leaves in small Roman numerals in brown ink, erasing and altering the original series as needed.  The fifteenth-century leaves were unnumbered.  The complicated process of keeping this book updated is illustrated by the care that was taken to erase cross-references that were no longer accurate (for example see f. 199 where the readings for Remigius were once followed by a folio reference which was erased and replaced with “unius conf. et pont”).

The carefully regulated liturgy also helps dating the various sections within this volume.  The calendar was extensively reworked with additions and many saints apparently rewritten in red, making it difficult at times to determine the dates of all the changes.  The original entries date after 1255, probably c. 1260, and include for example, Genevieve, commemoration (i3) (1257); Peter martyr, in black, with indication of twelve lessons in red (iv30) (1255); John before the Lateran gate (v6), in black, twelve lessons (observed with 12 lessons and a Mass, 1246); Margaret (vii20) (commemoration 1260); and Dominic (viii5) (1255).

It was then extensively updated in the early fourteenth century, c. 1320-1330, by hand B to bring it up to date, both by adding feasts including Thomas confessor, in black, but with twelve lessons added in red (7iii) (1329), Ambrose, in red, twelve lessons added (iv1) (1300, two masses), Hugo (iv29), in black, (1321 comm.), Peter of Tarentaise, in red (v8), (1196 twelve lessons and Mass, 1294 two masses and proper readings), Louis confessor, added (viii25) (1298, 12 lessons, 2 masses), Octave of Bernard, twelve lessons (viii27) (1295), Jerome in red (ix30) (1300 two Masses), Wenceslas, added (ix28) (1302), and by re-writing feasts included in the original calendar in red (for example, Augustine (viii28) (two Masses 1300) and Eligius (xii1) (1230 commemoration, 1287, 12 lessons).  It was updated again in the fifteenth century, perhaps by Johannes Zürn in 1491 (hand C), when the Visitation, was added in red (vii2) (1476).  A different late medieval  hand added Eustace of Luxeuil (29iii) (not found in the usual Cistercian calendar).

Feasts included the original section of the Sanctorale confirm a date for the original of after 1255, and before 1294, since John before the Lateran gate (May 6), observed in 1246, and Dominic (August 5), observed in 1255, are included.  Peter of Tarentaise (8 May), observed from 1294, is found in a section copied by hand B in the fourteenth century.  In 1491 Johannes Zürn (hand C), copied large sections including those adding the Visitation, observed from 1476, and Anne, mother of Mary (1454 twelve lessons, although celebrated in some convents from 1375).
