The Author and the Authors of the 'Vita Ædwardi Regis:' Women's Literary Culture and Digital Humanities

Commissioned by Queen Edith in the 1060s, the Vita Ædwardi Regis (hereafter VER) has recently received substantial scholarly attention, including focus on identification of the author of this putatively anonymous text; the quest for authorial identification has until now proceeded with the assumption of sole authorship of the text. Lexomics, an open-access vocabulary analysis tool, adds digital strategies to more traditional literary and historical analyses; the Lexomic evidence indicates that the VER is a composite text built by multiple contributors under the direction of the queen. Not only did Edith's patronage cause the VER to be written, but her knowledge, and her personal and political interests, shaped the Life's content. Hers was the active, guiding intellect behind the entire text, and in two passages the VER appears not only to communicate the queen's intentions but also to preserve her voice. If any one person is to be identified as the 'author' of the VER, therefore, it is Edith, guiding a team of writers and scribes to tell her story.

Naming and Renaming Texts: Rubrics in Middle High German Miscellany Manuscripts

This article analyses rubrics in Middle High German miscellany manuscripts of short texts in rhyming couplets (Reimpaargedichte). A corpus consisting of 1433 rubrics from 68 manuscripts was created to be able to perform this study. As rubrics in medieval manuscripts were not authorial, but composed by scribes, they offer insights into the reception of the texts. This paper analyses their features and functions as a proxy to interrogate the standing and status of Reimpaargedichte between the thirteenth and fifteenth centuries. The main methodology is distant reading, i.e. the application and interpretation of statistical methods on a textual corpus. The features analyzed include the length of the rubrics, their level of variation, the presence of author names, and vocabulary. Although no general patterns regarding length nor level of variation were detected, some important conclusions can be drawn: 1. there were no clear markers of literary genre in rubrics; 2. authorship was mostly absent, except for some specific cases of famous authors; 3. relatively stable keywords were used to identify particular texts, but they were more common in manuscripts with narrative texts (Erzählungen) and less common in later manuscripts dominated by the genre known as Minnereden. Furthermore, the analysis revealed that rubrics used a series of linguistic procedures to show that they participated in a different speech act than the main text – they embodied an interaction between scribes and readers, in which the former framed the reception of the work.

Johannes Kepler's 'Somnium' and the Witches' Night Flight

This article explores the uses of the witches' night-flight in Johannes Kelper’s Somnium (1634). It situates Kepler's engagement with the motif in the broader context of debates on the reality of the night-flight among early modern witch theorists, including Kepler's contemporary and friend, Georg Gödelmann. It proposes that Kepler understood the night-flight as a phenomenon with a disputed reality status and, as such, an appropriate imaginative space through which to pursue the thought experiment of lunar travel. Consequently, it suggests that we ought not to dismiss Kepler's engagements with the figure of the witch as a vestigial medieval superstition (itself a problematic contention), but rather an interest characteristic of his age, and that we might find in the speculations of witch-theory the very beginnings of science fiction.

Medieval Authorship and Canonicity in the Digital Age – an Introduction

Jeroen Deploige and Jeroen De Gussem introduce Cluster 2 of Interfaces 8, on the topic of Medieval Authorship and Canonicity in the Digital Age.

Figures and Mirrors in Demetrios Triklinios's 'Selenography'

This article is about the interplay between diagrammatic representation, the mediation of mirrors, and visual cognition. It centres on Demetrios Triklinios (fl. ca. 1308–25/30) and his treatise on lunar theory. The latter includes, first, a discussion of the lunar phases and of the Moon's position in relation to the Sun, and second, a narrative and a pictorial description of the lunar surface. Demetrios Triklinios's Selenography is little-known (though edited in 1967 by Wasserstein) and not available in translation into a modern scholarly language. Therefore, one of the main goals of the present article is to introduce its context and contents and to lay down the foundations for their detailed study at a later stage. When discussing the Selenography, I refer to a bricolage consisting of the two earliest versions of the work preserved in Bayerische Staatsbibliothek, graecus 482, ff. 92r–95v (third quarter of the fourteenth century) and Paris, Bibliothèque nationale de France, graecus 2381, ff. 78r–79v (last quarter of the fourteenth century). I survey the available evidence concerning the role of Demetrios Triklinios (the author), John Astrapas (?) (the grapheus or scribe-painter), and Neophytos Prodromenos and Anonymus (the scribes-editors) in the production of the two manuscript copies. Next, I discuss the diagrams included in the Selenography and their functioning in relation to Triklinios's theory concerning the Moon as a mirror reflecting the geography of the Earth, on the one hand, and to the mirror experiment described by Triklinios, on the other. Finally, I demonstrate how, even though the Selenography is a work on lunar astronomy, it can also be read as a discussion focusing on the Mediterranean world and aiming at elevating its centrality and importance on a cosmic scale.

Reversals in Wartime: Alcuin and Charlemagne discuss Retrograde Motion

The apparent retrograde motion of the planets was a puzzle for astronomers from the ancient world to the final establishment of heliocentric cosmology in the early modern period, but enjoyed an especially rich discussion in the Carolingian Renaissance. We explore the first stirrings of an eighth-century response to this epistemological challenge in a remarkable series of letters between Alcuin of York and Charlemagne, sent while the latter was on campaign against the Saxons in 798 CE. Their exchange constitutes the longest discussion of the phenomenon of Mars' retrograde motion in the West up to that date. Our consideration of the relevant letters explores Alcuin's ability to marshal diverse and complex explanatory narratives and observational traditions around the problem of the retrograde motion of the planet Mars, even as he was unable to fully reconcile them. Attention to his ultimately unsuccessful (and at times contradictory) attempts at explanation suggest that he relied on knowledge from sources beyond those previously recognized, which we identify. Charlemagne's curiosity about the matter can be located in the much longer context of an ancient tradition of imperial and royal concern with heavenly phenomena; at the same time, the exchange with Alcuin heralds the ninth-century expansion of astronomy away from the computists' preoccupation with the solar and lunar calendrical data required to calculate the date of Easter and towards a more wide-ranging curiosity about observed planetary motion irrelevant to Easter dating and computistical calculations. Alcuin's functional, if not geometrical, assumption of the centrality of the sun in his explanation merits a further examination of the more general sense in which lost ancient heliocentric ideas sustained early medieval echoes.

Larger than Life? A Stylometric Analysis of the Multi-Authored 'Vita' of Hildegard of Bingen

This article explores by aid of stylometric methods the collaborative authorship of the Vita Hildegardis, Hildegard of Bingen's (auto-?)biography. Both Hildegard and her biographers gradually contributed to the text in the course of the last years of Hildegard's life, and it was posthumously completed in the mid-1180s by end redactor Theoderic of Echternach. In between these termini a quo and ante quem the work was allegedly taken up but left unfinished by secretaries Godfrey of Disibodenberg and Guibert of Gembloux. In light of the fact that the Vita is an indispensable source in gaining historical knowledge on Hildegard's life, the question has often been raised whether the Life of Hildegard is – by dint of contributions by multiple stakeholders – a larger-than-life depiction of the visionary's life course. Specifically the 'autobiographical' passages included in the Vita, in which Hildegard is allegedly cited directly and is taken to recount biographical information in the first-person singular, have been approached with suspicion. By applying state-of-the-art computional methods for the automatic detection of writing style (stylometry), the delicate questions of authenticity and collaborative authorship of this (auto?)hagiographical text are addressed.

Advances in Distant Diplomatics: A Stylometric Approach to Medieval Charters

The quantitative analysis of writing style (stylometry) is becoming an increasingly common research instrument in philology. When it comes to medieval texts, such a methodology might be able to help us disentangle the multiple authorial strata that can often be discerned in them (issuer, dictator, scribe, etc.). To deliver a proof of concept in 'distant diplomatics,' we have turned to a corpus of twelfth-century Latin charters from the Cambrai episcopal chancery. We subjected this collection to an (unsupervised) stylometric modelling procedure, based on lexical frequency extraction and dimension reduction. In the absence of a sizable 'ground truth' for this material, we zoomed in on a specific case study, namely the oeuvre of the previously identified dictator-scribe known as 'RogF/JeanE.' Our results offer additional support for the attribution of a diplomatic oeuvre to this individual and even allow us to enlarge it with additional documents. Our analysis moreover yielded the serendipitous discovery of another, previously unnoticed, oeuvre, which we tentatively attribute to a scribe-dictator 'JeanB.' We conclude that the large-scale stylometric analysis is a promising methodology for digital diplomatics. More efforts, however, will have to be invested in establishing gold standards for this method to realize its full potential.
