Notaries in Medieval and Early Modern Ireland

In June of 2023, I arranged to meet my friend and fellow historian Caoimhe Whelan for a short breakfast during one of my rare trips to Ireland. I had given the rest of the day over to research, a concession of one day in what was supposed to be a family holiday. At breakfast, Caoimhe introduced me to Stuart Kinsella, Christ Church Cathedral’s Research Advisor; he was chasing down the scribes and notaries of the Cathedral’s later medieval manuscripts, and had run across a few pages at the back of my dissertation – an appendix cataloguing all of the notaries I had found in the process of investigating the life and career of Anglo-Irish author and notary James Yonge. In introducing me to Stuart, Caoimhe inadvertently cancelled my vacation. Breakfast was consumed. We talked. We ordered coffee. Stuart got out his carefully compiled list of notaries. We talked some more. Soon we were ordering lunch. We compared images, debated the merits of early 20th-century drawings of documents lost in 1922 in a catastrophic fire a half mile from where we sat, and began making plans. By the end of the morning, we had explored several possibilities for a project far wider than my study of James Yonge or Stuart’s study of Christ Church scribes and notaries. Every spare moment I could get for the rest of my time in Ireland was given over to notaries. (Caoimhe would go on to destroy my summer holidays the following year with a grainy image of a notarial signum taken at Sarah Graham’s lecture at Leeds, but that is a tale for another time.)

Notaries were specialized legal scribes used principally by the ecclesiastical courts to record proceedings and produce official documents. Notaries could be found in every corner of medieval and early modern Europe, and were particularly prevalent on the Italian and Iberian peninsulas where they also played a role in civil courts. In England and English-controlled Ireland, English civil law did not provide for notaries, and as a result they were far fewer in number. Notaries found their way, however, into civil procedures, particularly in cases where an official witness was needed. Notaries not associated with the church were paid by laypeople to produce documents that might be helpful in future cases in the ecclesiastical courts, particularly those regarding marriage or legitimacy. In Anglo-Ireland, these specialized scribes also created new, authenticated copies of documents that had become faded or damaged. Notaries also served as official witnesses in disputes, creating documents functioning similarly to a sworn deposition; their instruments record in a matter-of-fact way dramatic moments in the lives of ordinary people. For instance, a 1406 instrument of James Yonge records that Robert Burnell wanted John Lytill to place his seal on some documents; Lytill refused, and Burnell responded by seizing Lytill in a Dublin street and holding him hostage until he acquiesced. Another instrument by Thomas Baghill records an attempt to interfere in a will. On his deathbed, William Moenes was approached by his brother, Robert, who attempted to claim William’s property, despite the objections of William himself, who even in his extremity protested that he wished his property to go to his uncle’s daughters. Both of these instruments were probably intended for later use in civil cases regarding the disposition of property. Notarial instruments are most notable for their signa. Each notary developed his own unique signum manuale, a pen-and-ink drawing that he used to authenticate the documents he created. These frequently looked like altar crosses. During the Tudor period, notarial signa became panels of knotwork.

Once developed, a notary’s signum remained fixed; he would use the same signum for the rest of his career. On an instrument, the signum manuale is also accompanied by an eschatocol, a formulaic attestation that the notary has heard and witnessed what is recorded in the document and that the contents are true to the best of the notary’s knowledge. Eschatocols frequently begin with an E that can be quite plain or highly ornamented, depending on the notary. Again, notaries’ Es tended to remain somewhat fixed. The signum and eschatocol provide a key to identifying a notary’s handwriting in other contexts. For instance, James Yonge was also the scribe of over one hundred surviving documents, signed and unsigned. Notary William Somerwell, who worked for the archbishops of Armagh, was also one of the principal contributors to the registers of archbishops Nicholas Fleming (1404-1416), John Swayne (1418-1439), John Prene (1449-1453), and John Mey (1443-1456).

Signa have also been instrumental in identifying groups of notaries. For instance, James Yonge’s student Thomas Baghill borrowed portions of his master’s signum when developing his own.

Our survey of Anglo-Irish notaries is still in its infancy, and we are seeking sources of funding. We are currently trying to document as many notaries from medieval and early modern Ireland as possible as an entry into a larger exploration of notaries’ training, scribal networks, and documents. We hope to create a searchable online database of notarial marks and scribal hands for Ireland as a starting point for a more extensive resource cataloging the marks of medieval and early modern notaries of the British Isles. We would also love to see a future collaborative database of European notaries.

            Ian Doyle once wrote of palaeography that “the jigsaw puzzle we are all working on is so big that it may need the help of every eye to try to fit a piece in it.”[5] We believe the same is true of medieval and early modern notaries. This is where you, dear reader, come in. We heartily invite researchers in any area of medieval and early modern Europe to let us know about any notaries or notarial signa you encounter in your own research. The project’s email address is notarius.ie@gmail.com. We welcome your comments and contributions!

Eastern Liturgical Rite(s) under Pope Innocent III

The Roman Pontiffs, over the course of the second half of the Middle Ages, were not noteworthy for their enthusiasm for the liturgical rites of the Eastern Christian Churches. In few cases was this made clearer than in the aftermath of the Fourth Crusade, an especially distasteful moment of intra-Christian violence that left the Latin crusaders, originally destined for the Holy Land, instead governing the capital city of the Eastern Roman Empire. Although he initially decried the violence, Innocent III, then the Pope of Rome, quickly attempted to eradicate some of the liturgical differences that had plagued relations between the Roman and Constantinopolitan Churches for the previous century and a half, ever since the ill-fated trip of Cardinal Humbert and his co-legates to Constantinople in 1054. Among other changes, all new bishops, whether Greek or Latin, were to be consecrated according to the Roman rite, Latin clergy were to be appointed to those churches that had been abandoned by Greek priests fleeing the crusaders, and those Greek clergy who remained were to be encouraged to switch to the Latin rite for the celebration of the Eucharist [1]. Although he was not privy to the election of Thomas Morosini as the (Latin) Patriarch of Constantinople in the wake of the city’s conquest, he quickly confirmed him in his office and clarified that he would have the traditional jurisdictional authority of the Constantinopolitan See [2]. All of this transpired prior to the Fourth Lateran Council in 1215, with its famous canon dealing with “the pride of the Greeks against the Latins.”

This policy, in fact, marked a sharp deviation from Innocent’s prior treatment of the Greek rite. Too easily forgotten is the fact that the Greeks had a substantial presence in much of the Italian peninsula (and to this day there exists in Italy a few thousand people who speak Griko, essentially a dialect of medieval Greek). Alongside this substantial Greek population were Greek-rite monastic establishments and a number of dioceses served by Greek prelates, all of which were under the ultimate jurisdiction of the See of Rome. Innocent III, in his dealings with these communities prior to the Fourth Crusade, was noticeably less aggressive, balancing his apparent preference for the Latinization of ordination rites with a policy of non-interference on the matter of clerical marriage and active support for Basilian monasteries under his jurisdiction [3].

It has been popular with some modern commentators, Joseph Gill being perhaps the foremost example, while admitting that Innocent III had a distinct preference for the Latin rite, to argue that he was primarily concerned with enforcing (Latin) canon law. In this reading, the chief concern of the papacy was the allegiance of the Eastern clerics; once that had been secured, the secondary priority was to extirpate practices that were actively contrary to the law of the Roman church while at the same time tolerating, to a greater or lesser degree, ritual aspects that didn’t interfere with canonical norms [4].

To see whether this was in fact the case, helpfully, there are two other points of comparison. The activity of the crusaders in the Levant occasioned a resumption of active communication and communion between the Papacy and the Maronite Church. As part of this exchange, Innocent III issued a papal bull in January of 1215 in which he formally accepted the Maronite Church and confirmed several of its privileges. At the same time, though, he demanded certain changes: the Maronite Church must maintain the truth of the filioque, that only a single invocation of the Trinity be made during the rite of baptism, that the sacrament of Chrismation/Confirmation be done only by a bishop, and that the bishops wear vestments according to the Roman use [5]. In Bulgaria, facing a tsar and a primate eager to secure legitimacy for their positions and the autocephaly of the Bulgarian church, the subordination to Rome likewise came with a demand. As in Constantinople following the Latin conquest and in some of the Greek communities in the south of the Italian peninsula, the Roman rite was to be used for the ordination of priests and bishops [6].

These distinct differences in approach gives rise to the obvious questions: Did Pope Innocent III have a consistent stance toward the liturgical rites of the Christian East and, if so, what was it? Is it really fair to suggest that the pope was motivated first, by the question of allegiance, and second, to matters of ritual? Perhaps this was the case, but my sense is that the matters were more closely linked than many commentators assume. My suspicion is that, for Innocent, the willing submission of various Greeks, Bulgarians, and Lebanese to aspects of the Roman rite was itself the proof that they also accepted papal authority more broadly. I think that modern scholarship often fails to appreciate the intimate connection between practice and belief — lex orandi, lex credendi, after all — and that this is especially the case when it comes to the ritual differences that divided the churches of Rome and Constantinople. By requiring concrete changes in ritual practice, down to the style of vestments to be worn by the Maronite clergy, Innocent III caused these churches to give physical, tangible proof that they accepted the teaching, jurisdictional, and legal authority of the Apostolic See.

Mathematical “Small Things” and the Quadrivium

What did early mathematical education look like in the Middle Ages? As is commonly known, the ideal Liberal Arts curriculum of the Middle Ages featured both the Trivium (dedicated to the study of words) and Quadrivium (dedicated to the study of nature in the form of mathematical arts). The Trivium included Grammar, Logic, and Rhetoric. The Quadrivium consisted of Music, Astronomy, Geometry, and Arithmetic. These seven ways (viae) of liberal arts learning prepared students who studied them diligently to “comprehend everything that they read, elevat[ing] their understanding to all things and empower[ing] them to cut through the knots of all problems possible of solution” (John of Salisbury, Metalogicon I.12). Even today, the concept of a Liberal Arts education that prepares a student for life and whatever (foreseen and unforeseen) challenges lay aheadremains. And yet, for anyone who has educated a child, the idea of delaying mathematical education until the early teen years (which is when the formal Quadrivium was taught) seems completely impractical and misguided.

Did medieval educators really wait until students had a full understanding of the Trivium before introducing mathematics? The difficulty here comes in part from the lack of extensive knowledge of the curriculum of early childhood medieval education, including mathematical instruction. The institutions for learning changed over time and even geographic region. Early childhood education could take place in a home, in a monastery, or at a local cathedral school. Another difficulty may also be that our cultures mean slightly different things when we talk about the discipline of mathematics.

The “paper trail” for exactly what early childhood mathematical education might have looked like is not vast. But one tiny, but vivid, glimpse of what boyhood mathematical pursuits might have looked like can be seen in the writings of Hugh of St. Victor, an early twelfth century canon regular who wrote a book on the Liberal Arts called the Didascalicon. In this work, Hugh of St. Victor gives a rare view of his own early mathematical education:

I laid out pebbles for numbers, and I marked the pavement with black coals and by a model placed right before my eyes, I plainly showed what difference there is between an obtuse-angled, and an acute triangle. Whether or not an equilateral parallelogram would yield the same area as a square when two of its sides were multiplied together, I learned by walking both figures and measuring them with my feet. Often I kept watch outdoors through the winter nights like one of the fixed stars by which we measure time. Often I used to bring out my strings, stretched to their number on the wooden frame, both that I might note wih my ear the difference among the tones and that I might at the same time delight my soul with the sweetness of the sound. These were boyish pursuits…yet not without their utility for me, nor does my present knowledge of them lie heavy upon my stomach. (VI.3)

Hugh describes these activities as grounding him “in things small” so that he could “safely strive for all” later in life.

Notice how many of the activities mentioned by Hugh of St. Victor do not require a textbook at all, especially with a charismatic teacher, or in the case of Hugh’s own life, a particularly inquisitive child. Counting and the study of angles required only pebbles. The figuring of surface area required only the measurement of feet. An early acquaintance with the stars required actually going out to look at the night sky, even when it was cold, and the study of the relationship between musical notes came from literally fiddling around with a simple stringed instrument. To these activities, we might presumably add the common medieval practices of singing (cantus) and possibly dancing in set patterns. Or the calculating of times and seasons (computus). Or measurements of land and sea masses for commerce or geography. Or ratios for cooking. Many of these activities can be conveyed orally through constant interaction with numbers in the physical world. That is not to say that no formal study or book learning could or was be done in these areas, but the bulk of early mathematical learning did not need to take place in a school environment with a textbook. All that was needed was a student, the physical world, and a teacher with mathematical knowledge.

What Hugh recognized was that these mathematical activities, whether for play or practical application, were essential for what he and his contemporaries would have considered the formal discipline of mathematics as a liberal art (i.e. the Quadrivium), which would have taken place during the teenage years at higher level schools. Hugh distinguishes arts and disciplines in the following manner: “Knowledge can be called an art ‘when it comprises the rules and precepts of an art’ as it does in the study of how to write; knowledge can be called a discipline when it is said to be ‘full’ as it is in the ‘instructional’ science, or mathematics” (II.1).

 In other words, the sorts of activities Hugh describes himself doing as a boy were not mathematical disciplines in his terminology. Instead, his boyish mathematical play was both pleasant at the time and useful as he grew up to study the mathematical disciplines. For this reason, Hugh praised such activity as best because it aids one’s movement “step by step” rather than “fall[ing] head over heels when [attempting] to make a great leap ahead” (VI.2). This learning process mirrors the original discovery of the disciplines themselves by humanity. As Hugh writes:

Such was the origin of all the arts; scanning them all, we find this true. Before there was grammar, men both wrote and spoke; before there was dialectic, they distinguished the true from the false by reasoning; before there was rhetoric, they discoursed upon civil laws; before there was arithmetic, there was knowledge of counting; before there was an art of music, they sang; before there was geometry, they measured fields; before there was astronomy, they marked off periods of time from the courses of the stars. But then came the arts, which, though they took their rise in usage, nonetheless excel it. (I.11)

Early childish mathematical play was not the Quadrivium, but Hugh considered it a necessary preparation for the later study of the Quadrivial arts. Just as Boethius argued in Institutio arithmetica 1,1,7 that the quadrivium provides steps (gradus) by which the mind is progressively illuminated and can raise itself from its immediate sensible circumstances to the certainty of intelligible truth, so Hugh argued that the humble mathematical play of childhood was one step on the way to learning the discipline of mathematics. Computus, stargazing, learning to sing, learning to dance, and making geometric shapes with pebbles—none of this was Quadrivium. These activities could be boyhood pursuits…or in some cases, ends in themselves practiced into adulthood, but activities of this sort were, in Hugh’s opinion, a necessary preparatory step for the Quadrivial disciplines.
