ABSTRACT

 

This thesis provides the first comparative = analysis=20 situating the chants of Hildegard von Bingen within the = mid-12th=20 century Cistercian liturgical reform. =20 In applying Cistercian theory, a clear distinction between the = melodies=20 written before and after Hildegard=92s move to the Rupertsberg is = exposed.  In practice, her later chants=20 demonstrate shared compositional strategies and motifs with the chants = composed=20 under the Cistercian reform, as evidenced by antiphonals from the third = quarter=20 of the 12th century. =20 Moreover, cross-referencing subjects represented within the = Dendermonde=20 Codex with those feasts added to the Cistercian calendar between 1150 = and 1175=20 suggests that the liturgy celebrated at the Rupertsberg was Cistercian=20 influenced.  A review of = Hildegard=92s=20 correspondence in her later years suggests that she intended the = Cistercian=20 liturgy to continue after her death.

Symphonia Caritatis: The = Cistercian=20 Chants of Hildegard von Bingen

 

=85at God=92s admonition I paid a = visit to Mount=20 St. Disibod=85where I presented the following petition to all who dwelt = there: I=20 requested that our monastery, as well as the alms accruing therefrom, be = free=20 and clear from their jurisdiction, for the sake of the salvation of our = souls=20 and our concern for the strict observance of the Rule.[1]­=20 - Hildegard von Bingen to her = congregation of nuns=20 (ca. 1170)

 

For = the past 20=20 years, the popular perception of Hildegard von Bingen in the United=20 States has been one of New Age feminist = prophet=20 whose songs and visions shout out the virtues of 21st century = female=20 empowerment from the desert of a medieval patriarchal society.[2]  Even the more serious graduate = studies=20 which focus on her use of feminine imagery tend to exclude many = significant=20 contextual details by referring to the same limited core sources.[3]  Although far from stating this = is a bad=20 thing, the lack of diversity in sources, methodology and the conclusions = drawn=20 from their analyses has served to uphold an unbalanced depiction of = Hildegard=20 among students and performers of her music.[4]=20

It = was an=20 article by Nico biographer, = Richard=20 Witts, appearing in Early = Music which=20 asked scholars and fans to mind the context of Hildegard within the = scope of=20 twelfth-century reform.[5]  In this article, Witts created = an=20 intuitive argument citing, among other things, numerous coincidences and = numerological conspiracy theories, to indicate that Hildegard may have = been created by the = Cistercians.  While his argument was lacking = in much=20 concrete evidence, his intuition regarding a Cistercian connection is = closer to=20 the mark than has been previously acknowledged.

The = argument of=20 a Cistercian connection especially in regard to Hildegard=92s music has = fallen=20 short due to the perpetuation of such assumptions as: one, Hildegard = maintained=20 the Disibodenberg liturgy when she established her own communities at = the=20 Rupertsberg and Eibingen; two, Cistercian liturgical theory was already = fully=20 developed and strictly practiced in the Rhineland during Hildegard=92s = lifetime;=20 and three, Hildegard wrote only for her community for the sake of = educating her=20 nuns.[6]  Mention of the Cistercians is = relegated=20 to the footnote as Hildegard scholars cite trends and tendencies on a = universal=20 level rather than examining the particulars of individual works.  Never has there been a serious = comparative analysis between Hildegard=92s chant with contemporary = Cistercian=20 theory and, more importantly, practice.

What = I attempt=20 here is a re-evaluation of sources with a redirected focus on the last = decade of=20 her life beginning around 1170 and concluding with her death in = 1179.  It is my intent to build upon = Witts=92=20 argument and present a case for a shared Cistercian liturgical practice = between=20 Hildegard and individual Cistercian communities.  At the core of my argument is = the=20 assumption that Hildegard, acting with foresight was concerned for the = spiritual=20 care of her community in the years after her death.  She feared that without her=20 intervention, the corrupting influences of her parent monastery at = Disibodenberg=20 and the lax clergy within her archdiocese of Mainz would lead her daughters away = from=20 salvation.  To counter, she and her provost Volmar established a=20 =93Cistercian plan=94 sometime around 1170. =20 The objective of this plan was to establish political, = theological and=20 liturgical ties with trusted communities who might intercede on behalf = of=20 Hildegard=92s two houses at Rupertsberg and Eibingen. 

The = effect of=20 their Cistercian plan is reflected musically in comparative analyses = between=20 Hildegard=92s chants with those found in contemporary Cistercian = antiphonals=20 composed for liturgical practice. =20 This approach will uncover a general trend of compositional = refinement in=20 Hildegard=92s chants toward the Cistercian aesthetic.[7]=20 My research demonstrates that the chants written prior to her move to = the=20 Rupertsberg in 1150 clearly extend beyond Cistercian liturgical = theory.  Conversely it finds that those = perceived=20 to have been written in her later years do indeed conform to the = principles of=20 the Cistercian liturgy.  = To be=20 clear, this is not to say that all of her chants are Cistercian and = therefore=20 acceptable by all Cistercian communities, but there is enough = compounding=20 evidence to support the argument that within her lifetime, the specific=20 Cistercian community of Villers found the practice of her chants=20 acceptable.  Moreover, the = evidence=20 uncovered supports Witts=92 hypothesis that the liturgy practiced at the = Rupertsberg was Cistercian.

The = sources=20 considered for this study include Hildegard=92s extensive body of = correspondence=20 in order to provide the political context which is lacking in her Vita, her last and most vivid = treatise,=20 the Liber diuinorum operum = which=20 reflects her latest theological writings, and finally provide = comparative=20 analyses by using Hildegard=92s chants as found in the Dendermonde Codex = and those=20 found in contemporary 12th century manuscripts of Cistercian = and=20 Benedictine provenance.

In = support of=20 my argument three fronts shall be addressed.  First, the political = climate  including contextual = background into the=20 Cistercian reform, the view of Hildegard=92s spiritual authority, as = well as her=20 strained relationships with her superiors in the archdiocese of = Mainz.  These together serve as the = catalyst for=20 her Cistercian plan. The second front provides an overview of the Divine = Office=20 within the monastic cursus. =20 Attention will be focused on the hour of Matins with a = description of its=20 two most prevalent chant types, antiphons and responsories. = Understanding the=20 Divine Office is crucial in establishing the context and ideology behind = the=20 Cistercian liturgical reform.  = The=20 third front provides detail of the main principles of the reform.  From here examples will be = drawn from=20 chants composed by the Cistercian reformers in the mid-12th = century=20 in order to demonstrate instances where they broke from their own = theory.  In the following chapter = Cistercian=20 theory is applied to all of the chants which appear in the Dendermonde=20 Codex.  Cross-referencing = these=20 chants with those known to have been composed earlier, confirms the = trend of=20 refinement in Hildegard=92s melodies. =20 The final chapter focuses on three of those chants, Spiritus sanctus uiuificans, = Karitas habundat, and Laus trinitati in relation to = Cistercian=20 theory as well as in Hildegard=92s own compositional sensibilities.

A Word about = Symphonia

Referring to=20 the chants contained within the Dendermonde Codex (ca. 1175) and the = Riesencodex=20 (ca. 1180) as the Symphonia = armoniae=20 celestium revelationum, has served to perpetuate the myth that all = of her=20 chants were conceived as a cycle, not that they were in fact a = collection of=20 chants written over Hildegard=92s compositional lifetime.  The term has been commonly = used due to=20 its appearance in the introduction of Hildegard=92s Liber Vitae Meritorum.[8]=20 I contend that what Hildegard knew as the Symphonia is actually a = smaller number,=20 approximated by those twenty-six chants whose texts appear in what = Barbara=20 Newman describes as the miscellany.[9]  Those, along with chants = determined to=20 have been written at the request of other communities, and those written = prior=20 to her move to the Rupertsberg, had been collected within the = supplemental=20 antiphonal we know today as the Dendermonde Codex and the Riesencodex=20 (Henceforth D and R).   =20

Therefore, when=20 referring to these chants, I will use the term coined by Catherine = Jeffreys cantus cum melodia (chant with = melody),=20 which appears to have been the preferred term used by Hildegard=92s = secretary and=20 biographers rather than to perpetuate the term Symphonia .[10] 

Background on the Cistercian = Reform

The = traditional=20 account regarding the origin of the Cistercian movement begins with its = founding=20 by Robert of Molesme (c. 1027-1110) who led a small band of companions = to=20 establish a new monastery at Citeaux in 1098.   The driving force behind = this move=20 was the desire to return to an authentic practice of = monasticism and=20 devote themselves to the practice of caritas.[11]  In order achieve this they = removed=20 themselves from the secular activities which they believed had so = cluttered and=20 corrupted the established Benedictine traditions epitomized in the late=20 11th century by Cluny.

The = spread of=20 the Cistercian order began under the abbots Alberic (1099-1109) and = Stephen=20 Harding (1109-1133). It was through their guidance that reform to=20 pre-Benedictine ways sought measures which imitated Christ in poverty = and in=20 evangelism.  In 1112 = Bernard of=20 Clairvaux and twenty-nine of his followers joined the abbey at Citeaux, = doubling=20 its size.  Within a year, = the=20 Cistercian movement was well underway, and soon after Bernard became = abbot of=20 his own abbey at Clairvaux in 1115. =20 Bernard=92s charismatic influence led to the establishment of no = fewer than=20 327 Cistercian foundations in France, Britain, Spain, Italy and well into Eastern=20 Europe between the years 1125 and 1151.[12]  There were 160 affiliated = daughter=20 houses to Bernard=92s abbey alone.  To=20 ensure unity of purpose, practice and matters of governance among these = many=20 houses, the Cistercian abbots met annually in General Chapters.[13]  

The = attraction=20 to the Cistercian movement by so many however made it difficult for the = monks of=20 Citeaux and Clairvaux to remain removed from the secular world.  It also made it difficult to = enforce=20 uniform practice among the new houses. =20 Nevertheless, through continual recruitment from lesser nobility, = as is=20 the case of Bernard of Clairvaux and his family, and land donations from = the=20 likes of Theobold of Blois, Henry of Troyes and Emperor Frederick = Barbarossa,=20 the Cistercians became economically prosperous.[14]  Moreover, between 1137 and = 1147=20 Bernard=92s fame kept him fully embroiled in the affairs of Church and = State=20 including his role as intermediary between Louis VII and Thibault, Count = of=20 Champagne.[15]=20 Through Bernard=92s influence, the Cistercian order gained a = considerable=20 political foundation which culminated in the election of the first = Cistercian=20 Pope, Eugenius III (1145-1153). =20 Coupled with their evangelistic attitude, the Cistercians = preached out=20 against the Cathar heresy and became dominating forces for the Second, = Third and=20 Fourth Crusades.[16]

Life in Cistercian=20 Communities

In = their drive=20 toward authenticity, the Cistercians modeled their community on the = ideal monk,=20 St. Benedict of Nursia (480-547) and therefore strove to live in strict=20 observance of the Rule of St. Benedict. =20 Their zeal for authentic practice did not end there for they also = re-examined the works of those authors which were likely known by St.=20 Benedict.  The greatest = impact from=20 this train of thought is noted in the reform of liturgical practice. = Initially=20 they adopted what they believed were the =93original=94 chants of Pope = Gregory I=20 (540-604) supplemented with hymns composed by St. Ambrose of Milan (ca=20 337-397)
