(Pseudo-) Peter Damiani and the Reception of the Schism

In stark contrast to the almost non-reception of the events of 1054 in the literary Byzantine world, discussed here, on the Latin side of the equation, the report of the legation penned by Cardinal Humbert of Silva Candida quickly found its way into various historical chronicles and into theological literature. Two particularly fascinating examples that appear in Patrologia Latina 145 are both published under the name of Peter Damiani, who was, together with Humbert himself, one of the leading members of the papal curia in the mid-eleventh century. Although he would not be elevated to the cardinalate until 1057, under Pope Stephen IX, by the time of Humbert’s legation to Constantinople he was already active in attending various synods and had written the deeply influential Liber Gomorrhianus (addressed to Pope Leo IX). What makes these two works interesting, in light of their purported joint authorship, is that they take views of the azyme conflict (the use of unleavened bread in the celebration of the Eucharist) that are at odds both with each other and with the stance adopted by the Humbertine legation.

The first example is a letter fragment written by Peter Damiani to Henry, the Archbishop of Ravenna, most likely between 1052 and 1058 [1]. The text is eye-opening both for the historian and for the contemporary canonists, so I’ll cite the full text of Fr. Blum’s translation:

…Just as it makes little difference whether at Mass we offer wine or unfermented grape juice, so, it seems to me, it is all the same whether we offer leavened or unleavened bread. For that “living bread that came down from heaven,” just as he wished to manifest himself under the appearance of wheat, he did so also under the form of the vine. “Unless,” he said, “a grain of wheat falls into the ground and dies, it remains a solitary grain.” And again, “I am the real vine.” Therefore, it suffices for me to offer either whatever is made from grain or whatever is produced by the vine. Nor am I too careful to inquire whether the bread was preserved in an immature dough until it could ferment, or also whether the grape juice was kept in a vat until it could turn into what one calls wine. But since it is not my purpose here to discuss these matters, I leave them to be handled by others…. [2]

Peter Damiani here showed himself to be vastly more permissive than most of the mainstream Latin West when it comes to the correct materials for confecting the Eucharist, and even more tolerant than the legates to Constantinople. Humbert, while he tacitly acknowledged that the Greek practice of using leavened bread was permissible, also had a clear preference for the unleavened Latin host. Peter, interestingly, does not here even mention the Greek practice: his letter is entirely within the context of the Latin rite, addressed to an archbishop of an (admittedly Byzantine-influenced) Latin see. This text allows us to see an approach very different from the one that appears in the aforementioned Liber Gomorrhianus. Given the fact that this was a topic of considerable polemics when he wrote the letter, Peter Damiani appears as a moderating, or even progressive, voice in the conflict.

What a surprise, then, when we examine the second text, taken from the Expositio canonis missae. The work as a whole falls into the genre of Mass commentaries, theological treatises that explain the various ritual components of the eucharistic celebration with historical or scriptural parallels and allegory. Fairly early in this treatise, while discussing the phrase “He took bread” (“accepit panem”) the author complains:

Leavened bread should not be offered in the sacrifice, both by reason of deed and by reason of the mystery. As is read in Exodus: “Leaven signifies corruption”, and as the Apostle witnesses: “A little leaven corrupts the whole lump”. But the Greeks, persisting in their error, celebrate [the Eucharist] from leaven. [3]

Now present is a direct mention of the conflict with the Greeks, using scriptural references that were first applied to the debate by the Humbertine legation. And gone is the tolerance of the previous passage, in which the matter of the Eucharist – so long as it comes from grapes and wheat – is a matter of indifference. Instead, for the author, the use of leavened bread violates the spiritual message of the scriptures, signifying corruption, and is therefore wholly unsuitable for the celebration of the Eucharist. 

The wildly divergent views, of course, lead the reader to question the traditional attributions of authorship for one or both of the passages, and indeed, the Expositio canonis missae has caught the attention of several scholars for containing passages that seem out of place in the literary corpus of Peter Damiani. In particular, the text uses the word “transubstantiation” (“transubstantiatio”), which would be the first appearance of this terminology if it could, in fact, be dated to the middle of the eleventh century. It is this terminological incongruity that caused Joseph de Ghellinck to conduct a line-by-line comparison with other commentaries on the Mass and to conclude that the Expositio postdates not only the De sacramentis of Hugh of St. Victor (d. 1141) but also the De sacro altaris mysterio of Lothar of Segni (later Pope Innocent III), which was written in 1198 [4]. The true date of composition, then, would fall somewhere around the turn of the thirteenth century, about a hundred and fifty years after originally supposed.

When applied specifically to the passage about leavened bread, this reattribution to an anonymous author of the thirteenth century clears up a couple of difficulties. In the first place, the notion of the Greeks persisting “in their error” makes much more sense with the later dating. The use of un/leavened bread in the Eucharist didn’t arise as a point of contention until the 1050s, so the Greeks couldn’t have persisted in the error for very long if it had been Peter Damiani admonishing them. By the year 1200, of course, Latin polemicists could much more reasonably suppose that the Greeks had been given sufficient warning, and therefore that their continued use of leavened bread qualified them as “persisting” (“pertinaces”). Similarly, the hard-and-fast rule that “leavened bread should not be offered” is much more typical of the later period, in contrast with the more permissive attitude found in the eleventh century. We see, for example, an identical notion, in nearly identical phrasing expressed in Lothar’s De sacro altaris mysterio: “Not leavened bread, but rather unleavened, should be offered in the sacrifice, both by reason of deed and by reason of the mystery” [5].

But I want to conclude with an emphasis on the relative openness and permissiveness of the mid-eleventh century. Contrary to the reputation that the events of 1054 have developed in the centuries since, the Latin Christians at that time had only begun to develop their stance on the various points under discussion, un/leavened bread being maybe the most important among them. Had the more irenic figures like Peter Damiani (and even Humbert!) exercised a little more influence on this topic, the West might have maintained a more permissive tone by the time of the authorship of our Pseudo-Peter, and indeed, perhaps a different approach taken under the leadership of Innocent III, who had clearly been swayed by a century and a half of increasing aggressive liturgical polemics in his approach to the Greek rite. Whether openness to a variety of liturgical forms could have prevented the entirety of the calamity of the Fourth Crusade is doubtful, but it certainly couldn’t have hurt.

Could Medieval Women Read?

As a specialist in the study of women’s education and literacy in England in the Middle Ages, I’m asked this question a lot. I’ll cut to the chase: YES. 

How do we know this? 

Medieval England (on which I’ll focus this blog) was a multilingual nation.1 English had been its primary vernacular from the time of the Anglo-Saxons (about 450) until the Norman Conquest of 1066, when French became the language of the nobility, government, and diplomacy.2 By the mid-fifteenth century, though, English had reasserted dominance as the primary vernacular language, while the Church, clerics, and higher education continued to use Latin.3 Because medieval English people would have heard and used all three languages in daily life, children were taught to read and speak all of them.4 Whether children’s reading knowledge became advanced depended on the importance of reading in their lives and what socioeconomic station they attained. In fact, most of the evidence for literacy survives from the upper classes; uncovering the history of less privileged groups remains difficult. 

In infantia

Medieval scholars commonly thought of childhood in three divisions: infantia (birth to about 7 years), pueritia (about 7 to 14 years), and adolescentia (about 14 to 21 years).5 The teaching of reading began in infantia with parents and nurses, if the family could afford such help. 

Girls and boys began by learning the letters of the Latin alphabet and the sounds they made. In this way they acquired the basic skills of early reading, called contemporaneously sillibicare (sounding out syllables) and legere (sounding out words), even if they didn’t understand what those sounds or words meant.6 Singing might have been used as well to teach pronunciation, as sung Latin was used in church services. Because reading was important to promote spiritual instruction, and had indeed been cited at least as far back as Jerome in the fourth century as a reason girls should be taught to read, some of the earliest texts learned were the Pater Noster, the Ave, and the Creed. Alphabets and these simple prayers could be written out on a variety of surfaces: boards, painted walls, wooden trays covered in ash or sand, ceramic or metal vessels, or hand-held tablets made of materials such as slate, horn, or board covered in parchment (more on this below).

Beginning around 1300 in England, medieval parents had a model of teaching in St. Anne, the mother of the Virgin Mary. Depictions of her teaching Mary to read appeared in stained-glass windows, manuscript illuminations, wall paintings, and other artistic representations.7 One such survives today in the Church of St. Nicholas in Stanford-on-Avon, Northamptonshire, England.

In this window, Mary is shown sitting in Anne’s lap and holding a bound book with letters written on its pages. She holds the book open so the text is visible to the reader. Her mother Anne points upward, in a gesture both teacherly and pointing heavenward, perhaps emphasizing the importance of reading for spiritual development.8

This beautifully-painted miniature from a Book of Hours shows Anne and a young Mary holding a book together. With her right hand, Anne isolates text for Mary to examine.

Other surviving representations show Anne using a hornbook (mentioned above) to teach Mary to read. This illustration comes from a Book of Hours that originated in England around 1325­–1300.

This detail shows the hornbook more closely. 

Though the hornbook was at least a medieval invention (discussed recently by Erik Kwakkel and Trinity College, Cambridge, librarians), it survives only from early modern centuries, as in this example, created in London around 1625. The text is printed on sheepskin parchment and fixed to an oak paddle with a brass frame and iron nails; the handle is used for holding the hornbook. The parchment is laminated over with a processed animal horn (hence the name) to protect the text.

A text from the 1230s, written by a layman, Walter of Bibbesworth, also reveals much about how boys and girls learned, especially languages, in a gentry household. Bibbesworth was a wealthy English landowner and a knight who wrote this book for his neighbor and fellow member of the gentry, Dionisie de Munchensi. Dionisie had three young children to educate, and as part of the expectations of their class, they would have needed to learn a French more advanced than what they would have picked up through everyday living. The image below shows the opening leaf of Walter of Bibbesworth’s Tretiz

The opening leaf of Walter of Bibbesworth’s Tretiz. The manuscript dates from 1325. London, British Library, Additional MS 46919, fol. 2r. 

Walter addresses Dionisie in column 1, lines 10-20, identifying the purpose of his text: “Chere soer, pur ceo ke vous me / pryastes ke jeo meyse en ecsryst [sic] / pur vos enfaunz acune apryse / de fraunceys en breve paroles” (Dear sister, because you have asked that I put in writing something for your children to learn French in brief phrases). What follows is a narrative poem, beginning in column 1, line 21, that describes childhood, starting with birth and ending in young adulthood with a large household feast. In each scene, Walter presents French vocabulary for Dionisie’s children to learn.

Many clues in the text demonstrate that the physical book was shown to children so they could learn the reading of words on a page, not just the sounds of them. Walter gives many homophones, for example, that would only make sense in writing, rather than in pronunciation. Some of the vocabulary also has English translations written in between the lines of the main text. You can see this in the image above in the poem, which starts at column 1, line 21, and goes into column two. All the smaller words written between the lines give the English translation of the main text, which is written in French.

In pueritia and adolescentia

Once they moved into pueritia (about 7-14 years of age), girls of the upper classes would often transition into the care of a mistress (called at that time magistramagistrix, or maitresse). The mistress provided education in such things as deportment, embroidery, dancing, music, and reading.9 For any skills the mistress did not herself have, she could bring in other household members, such as the minstrel for musical training, the chaplain for more advanced reading and spiritual instruction, and the huntsman for hunting. Specialized academic tutors could teach girls more advanced academic subjects. Sometimes these well-to-do girls were sent to other households to be fostered, serving as ladies-in-waiting to upper-class women. Girls, especially those of the upper classes, could be sent to nunneries as well (sometimes beginning in infantia) for education. Not all girls sent to nunneries were meant for the vocation of nun.10

As their reading abilities progressed, girls and boys moved on to reading comprehension (intelligere) and began to read more sophisticated spiritual texts, such as prayer-books, books of hours, psalters, antiphonals, and saints’ lives. They also would continue on, as personal libraries grew in the thirteenth century, in reading romances, histories, poetry, classical authors, theology, philosophy, and more. It is most likely, given that women were not admitted to the university (unlike boys, who could progress from this stage to Latin grammar school and then on at a university level to the study of business, liberal arts, medicine, canon or civil law, or theology), that the reading of these last few would have been limited to girls whose families could afford private tutors.

Miscellany of religious, medical, and secular verse and prose in French, Latin and English. Oxford, Bodleian Libraries, MS Digby 86, fol. 68r. Produced in Worcestershire, England, c.1271–83, this “common-place book” contains French, Latin and eighteen English texts of various genres including fabliau, romances, devotional and didactic texts, prognostications, charms and prayers, among others written between 1271 and 1283. The manuscript was written by its owner and has amateurish scribal drawings and decoration. This image shows three sections of French text: the end of the hymn Veni Creator Spiritus (Come, Creator Spirit) (top 11 lines); a list of the unlucky days in the year (middle section of the text); and at the bottom a list of Arabic numerals 1 through 46. Three shields decorate the bottom. 

In adulthood

By the time they reached adulthood, women who were privileged enough to have obtained a sophisticated education and their own libraries could be avid readers. 

Gospel lectionary written in Latin, made in England c.1025–50, later owned by St. Margaret of Scotland. Oxford, Bodleian Libraries, MS. Lat. liturg. f. 5, fols. 21v–22r. This opening shows St. Luke with the start of his gospel reading. The Bodleian Libraries digital Treasures exhibition notes: “A compact selection of passages from the Gospels, this finely illustrated book was Margaret’s favourite, and one she read and studied closely, even when she travelled. A poem added at the front describes how this very book was dropped into a river but remained almost unharmed: this miracle contributed to her growing reputation for holiness.”

The historical and literary records provide examples of such sophisticated learning, primarily among the nobility. For example, the Norman monk and chronicler Robert of Torigni (c.1110–1186), praised the education of St. Margaret of Scotland (d. 1093) and her daughter Matilda (1080–1118), wife of Henry I, writing, “Quantae autem sanctitatis et scientiae tam saecularis quam spiritualis utraque regina, Margareta scilicet et Mathildis, fuerint” (Of how great holiness and learning, as well secular as spiritual, were these two queens, Margaret and Matilda).11

In a different Latin life, commissioned by Matilda about her mother Margaret, the biographer describes how Margaret from her childhood would “in Divinarum lectionum studio sese occupare, et in his animum delectabiliter exercere” (occupy herself with the study of the Holy Scriptures, and delightfully exercise her mind) and notes that her husband, King Malcom III, cherished the “libros, in quibus ipsa vel orare consueverat, vel legere” (books, which she herself used either for prayer or reading), even though Malcom himself could not read Latin.12

London, British Library, Harley MS 2952, fol. 19v. Book of Hours, made in France c.1400–1425. 

This image above shows the unidentified female patron of this Book of Hours kneeling on a prie-dieu, her prayer book open to the text “Maria mater gratiae” (Mary, mother of grace). This open book with its discernable text has several functions: it leads the reader into the  prayer; it demonstrates the piety of the patron, kneeling in prayer before both her spiritual book and the Blessed Virgin and Christ (illustrated on the facing leaf); and it shows one of the primary purposes of teaching children to read: being able to use spiritual texts in personal devotion. 

Even women who were not noble and who were not able to read much Latin possessed and used books such as the one pictured above. In the mid-fifteenth century Englishwoman Margery Kempe wrote through her scribe of a memorable time in her church of St. Margaret in King’s Lynn when a chunk of masonry fell from the ceiling down onto her as she was praying with her prayer book in hand.

The image below comes from her Book of Margery Kempe as preserved in London, British Library, Additional MS 61823. Lines 24-28 narrate, “Sche knelyd upon hir / kneys heldyng down hir hed. and hir boke in hir hand. / prayng owyr lord crist ihesu for grace and for mercy. Sodeynly fel / down fro þe heyest party of þe cherche vowte fro undyr / þe fote of þe sparre on hir hed and on hir bakke a ston / whech weyd .iii. pownd” (She knelt on her knees, bowing down her head and holding her book in her hand, praying to our Lord Christ Jesus for grace and mercy. Suddenly fell down from the highest party of the church out from under the foot of the rafter onto her head and her book a stone which weighed three pounds). She survived, for which she credited the mercy of Christ.

Finally, a note on those of the working classes. I have not discussed them in detail as it is unfortunately difficult, in fact nearly impossible, to say much about the reading skills of those who left few or no records behind: the great majority of women (and men) of the medieval population were laborers who left little trace in the written record. Yet as we see from the image here below, even for working women, especially in the last few centuries of the Middle Ages, possession and use of books was within the norm, provided those books could be afforded.

Conclusion

My focus here has been tightly on the teaching of reading to medieval English girls. Girls and boys alike were taught to read, and began their reading education in the same ways. Boys alone could attend the medieval university and reach the highest (and best educated) ranks of clerics, but if girls had access to the right resources, they too could be highly educated. The evidence demonstrates that the teaching of reading was not linked specifically to gender; rather, it was a function of both socioeconomic station and the usefulness of such skills for one’s life.

If you’re interested in this topic, I cover the subject in much greater detail, with many other examples and suggested readings, in my article, “Women’s Education and Literacy in England, 1066–1540,” in the “Medieval and Early Modern Education” special issue of History of Education Quarterly, and the accompanying HEQ&A podcast.

Arguing against the Greeks: The Dominican Tractatus contra Graecos of 1252

Fragment of a floor mosaic (13th century) depicting the sack of Constantinople by the Latin crusaders in 1204; Ravenna, San Giovanni Evangelista

The Council of Ferrara-Florence (1438/39) is considered the last remarkable, though ultimately unsuccessful, attempt in the Middle Ages to restore church unity between the Latin West and the Greek East. Throughout history, certain events and their enduring consequences had nourished a growing scissure that ever deepened the alienation between the churches – just to mention a few of the most striking: the so-called Photian schism at the end of the 9th century, the mutual excommunications in 1054, the sack of Constantinople in 1204 followed by the Latin Empire of Constantinople until 1261, the Byzantine Emperor’s acceptance of an eventually short-lived church union on the Second Council of Lyons in 1274 (succeeded, though, by its refusal in 1282) etc. Following the history of reception of these events in the Middle Ages and beyond is like dealing with not only one, but several “points of no return”: While this might seem contradictory to itself, it nevertheless helps to understand (1) that dating the breakout of the schism depends on what kinds of sources we rely on, and (2) that, again throughout history, there have been many attempts and frequent parallel endeavours to heal this fracture between the churches.

© Viliam Štefan Dóci OP

One milestone of such an effort was the lifetime achievement of an anonymous Dominican from the year 1252, a learned theologian who dedicated himself to an in-depth study of the Greek language, theology, and church life. Based on this knowledge, he was capable and well-equipped to write a theological treatise “Against the Greeks” (Tractatus contra Graecos) in Constantinople, which eventually became a bestseller in controversial literature dealing with how to argue in Greek-Latin debates. Up to the 15th century, it greatly influenced theology and the Latin church and deeply affected how Latin authors perceived the Greek church. The anonymous Dominican was the first theologian who determined what later appeared on the agenda of the union councils in Lyon (1274) and Ferrara-Florence (1438/39): That a number of four issues of conflict – filioque, purgatory, azymes, and Roman primacy – had to be solved in order to proclaim the unity of the church, something which he didn’t see as lost, but as highly at risk. In a manner of fraternal correction, the Dominican author sought to convince the Greeks of their errors by quoting their own reliable sources, i.e. the Greek fathers and church councils, and by demonstrating that they all, in fact, supported the Latin positions. Additionally, he provided his (indented Latin) readers with a dossier of contemporary Greek writings in a Latin translation along with a commentary which was both meant to keep the readers informed about the situation on the spot and to support their argumentation in ongoing debates.

“Tractatus contra Graecos” (Inc.: Licet grecorum ecclesiam); Mantova, Bibliotecta Communale, Ms. Nr. 604 (D. I. 31), fol. 1ra-43rb, here: 1r

From today’s perspective, the actual value and impact of the Tractatus contra Graecos is impaired by the fact that today it is known only based on an early modern edition of 1616[1], which is deficient and at times almost incomprehensible. This is why an updated and reliable critical edition is a particularly urgent task: Based on 30 manuscripts that are known thus far and that are kept in libraries in Central and Southern or Southeast Europe, a critical edition will lead to a reconstruction of the text ranging from the time it was written in mid-13th-century Constantinople up to how it was used as a handout and source of information on the councils of the Late Middle Ages by leading Latin theologians. The surviving manuscripts give evidence that not only in the 15th century, but also already by the author himself, the treatise has been remodelled and shaped according to the needs of time and occasion. Both the critical edition of this Dominican key work and its history of reception contribute to a better understanding of the relationship between Rome and Byzantium in the Middle Ages and, thus, to a more detailed knowledge of the history of today’s Catholic and Orthodox churches.
