Digitization of the Enlightenment and Manifold Scholarship

Last month, Oxford University Studies in the Enlightenment released the first volume in the long history of the series that is devoted to the application of digital humanities methods to the study of eighteenth-century intellectual life, Networks of Enlightenment, edited by Chloe Edmondson and Dan Edelstein. To accompany this important and innovative book, we are pleased to be releasing our first-ever digital companion to an OUSE book through the Manifold Scholarship platform.

The digital companion site to Networks of Enlightenment 1 is hosted on the Liverpool University Press Digital Collaboration Hub, constructed on the Manifold Scholarship publishing platform. Funded by the Mellon Foundation, Manifold Scholarship is described as “the intuitive, collaborative, open-source platform for scholarly publishing you’ve been waiting for”. In their own words, the platform allows “for a much more expansive archive of primary sources, such as field notes, moving images, audio, interactive data and maps, photographs, interviews, and archival material” and “asks that an author think creatively about the broad set of materials that are collected in the process of researching and writing a book”.2 Liverpool University Press is participating in Manifold’s pilot program – this companion site is a pilot for the OUSE series as well.

The book at the center of this pilot for OUSENetworks of Enlightenment, focuses on the use of metadata to identify and represent social networks, such as those formed by correspondences, by academy affiliations or by the words in a text. As part of this work several contributors to the volume, using data visualization tools developed at Stanford’s Center for Spatial and Textual Analysis, created 40 data visualizations to demonstrate the structure and density of these network relationships. The visualizations are, in fact, crucial to understanding the arguments presented in this book.

Yet these figures, principally due to their complexity as images, can only be approximately reproduced in the medium of the print book; Manifold allows these figures to be rendered as they ought to be – online, in high-resolution and in full color. This supplemental platform thus opens up the possibilities when it comes to publishing digital humanities scholarship, in this volume and in the future. We hope in the coming years to continue this utilization of Manifold to offer our authors, and readers, scholarship that is innovative in method, in findings and in its format.

We are launching this companion site on July 16th, during the XVth International Congress on the Enlightenment which is being held during the same week in Edinburgh, Scotland, under the auspices of the International Society for Eighteenth-Century Studies. Today’s digital-focused day consists of the Voltaire Foundation-sponsored day-long workshop “Digitizing Enlightenment IV”, and will culminate in McEwan Hall at the formal launch (and drinks reception) for the Oxford University Studies in the Enlightenment ONLINE, the digital collection which will make available the entirety of the OUSE/SVEC backlist by the end of 2020. Both events will be an exploration (and a celebration) of the efforts already made thus far to consider how scholarship can be enhanced by digital methods, now and in the future.

1 The site, it is important to note, is not a full-text digital edition. The text consists of the full text of the book’s Introduction and Table of Contents, and brief summaries of the nine body chapters of the book.

The assembly of the site also had support from the College of Liberal Arts at University of Nevada, Las Vegas, which provided support for our time on this project.

Networks of Enlightenment: new approaches, new perspectives

While many ‘great men and women’ stand out in eighteenth-century Europe, what is notable about the Enlightenment is the prominence of its ‘great groups’, or, as we like to call them, networks. Many individuals owe their participation in the Enlightenment to their membership in intellectual groups and institutions: the philosophes, the salons, the academies… the list goes on. And these networks were, in turn, central to their participants’ identity. What’s more, the leading figures of the Enlightenment were not only members of these groups or networks, but they were often the central nodes of networks that were integral to the Enlightenment: from Voltaire’s or Catherine the Great’s correspondence networks to Julie de Lespinasse’s salon, mediated and unmediated communication were essential to making the Enlightenment possible.

Networks of Enlightenment, edited by Chloe Edmondson and Dan Edelstein, is the June 2019 volume of the Oxford University Studies in the Enlightenment series.

Networks of Enlightenment: Digital Approaches to the Republic of Letters presents a series of case studies of correspondence networks, social networks, and knowledge networks throughout Europe, with a particular focus on France. Authors examine anew some of the pre-eminent networks of the Enlightenment, drawing on digital methods and Social Network Analysis (SNA) to pioneer historically driven methods for thinking about networks in early-modern societies.

Although scholars have long zeroed in on the importance of social groups and networks in the Enlightenment, from networks of publishers and booksellers to provincial academies, the salons, and correspondence networks, technological innovations have only recently made it possible to study these networks from new perspectives. Data-driven approaches provide a more comprehensive and granular understanding of the many different types of networks that formed the intellectual and cultural infrastructure of the Enlightenment throughout Europe. The digitization of correspondence collections has been essential for data-driven scholarly projects, allowing scholars to study these networks at both the micro and macro levels, and to explore the worlds of the philosophes and the ‘nodes’ in their networks in rich detail. Indeed, it was thanks to metadata produced in large part by the Electronic Enlightenment Project at Oxford University that many authors in this volume first developed and applied methods for historical data analysis in a project reconstructing ‘The French Enlightenment Network.’

Working from historical data to study networks is not without its challenges, and one of the core concerns of this volume is how to responsibly study historical networks in the absence of complete data. At the most fundamental level, a social network is a system of actors (nodes) and the ties between them (edges). Social Network Analysis can be applied to virtually any type of network, and an SNA study relies on both information about the nodes and the relational ties between them. Reconstructing complete historical networks, however, is not only difficult and messy, but near impossible in most cases due to the quality of historic sources. Often, we do not know if someone was truly not ‘in’ the network, or if his or her membership was simply not recorded. The mathematical and statistical metrics typically used for SNA studies, which rely on complete or representative samples, would thus produce results that would distort reality when applied to historical data. As such, the adoption of SNA methods by historians requires creativity to tailor SNA methods to the object of inquiry, the data available, and the research questions at hand.

The authors of the essays in this volume do precisely that: they elegantly combine traditional humanistic inquiry with innovative digital methods to offer fresh perspectives on important networks and issues of the Republic of Letters. At this intersection of Enlightenment historiography, data capture, and social network analysis, the essays in this volume take advantage of new data sources, configurations, and modes of analysis to deepen our understanding of how Enlightenment sociability worked, who it included, and what it meant for participants.

Authors not only examine various types of networks, but they also use the term ‘network’ in very different ways. While part I of the volume concerns ‘correspondence networks’ with case studies of Voltaire, Catherine the Great, Francesco Algarotti, and Jacques Pérard, part II focuses on ‘social networks’, or who interacted with whom in milieus of sociability. These studies include Julie de Lespinasse’s salon, Gustav Philip Creutz’s Parisian networks, and Casanova’s theater network. Finally, part III examines ‘knowledge networks’ from two very different approaches: the first, by examining the role of the academies in the Republic of Letters, and second, the knowledge networks present in Johnson’s Dictionary.

This volume emerged out of a conference held at Stanford University in 2016, and it seems fitting that the first volume in the series Oxford University Studies in the Enlightenment dedicated to digital approaches to eighteenth-century studies would originate in the heart of Silicon Valley. This conference, which brought together an international group of scholars, demonstrated the exciting possibilities that can ensue when technological advancements are leveraged in the service of the humanities. Networks of Enlightenment: Digital Approaches to the Republic of Letters is very much the culmination of many years of figuring out how best to accomplish that, through interdisciplinary collaboration and experimentation on projects that preceded and gave rise to the ones contained in this volume.

Entretien avec Nicholas Cronk et Glenn Roe

For those who missed it first time round, here is another chance to read this interview with Glenn Roe and Nicholas Cronk, first published last January.

Glenn Roe et Nicholas Cronk.

Où en est la publication des Œuvres complètes de Voltaire par la Voltaire Foundation ?

Nicholas Cronk

La publication des Œuvres complètes de Voltaire a été initiée dans les années 1960 par Theodore Besterman, qui venait d’achever l’édition d’une gigantesque correspondance de plus de vingt mille lettres. L’édition qui faisait autorité, en quelque sorte, était encore celle de Beaumarchais et de Condorcet, imprimée à Kehl (1784-1785), car les grandes éditions qui lui ont succédé au XIXe siècle, comme celle de Louis Moland (1877-1885) reprennent son organisation. Seulement, l’édition de Kehl est un monument à la mémoire de Voltaire et pas véritablement une édition critique. L’organisation chronologique adoptée par la Voltaire Foundation, sur la proposition de William H. Barber, a permis d’éviter, par exemple, certains écueils de la classification générique, qui a du sens dans le cas des ouvrages d’histoire, des tragédies et de La Henriade, mais qui condamne les petits récits en prose, que Voltaire appelait « fusées volantes », à figurer dans des volumes de mélanges. L’édition de la Voltaire Foundation redonne leur place à ces textes, qui sont tout sauf mineurs. Elle sera achevée à l’automne 2020. Nous travaillons actuellement, par exemple, sur l’édition du Siècle de Louis XV, qui n’a jamais été éditée scientifiquement, sur les Annales de l’Empire et sur les Lettres philosophiques, qui sont plus connues.

Quel est le lien entre les Œuvres complètes et le projet Digital Voltaire ?

Nicholas Cronk

Publier les œuvres complètes de Voltaire est un travail infini et une édition numérique offre tout simplement l’avantage de pouvoir être régulièrement mise à jour, sans qu’il y ait besoin d’engager de moyens considérables. Le numérique permet également d’imaginer une édition critique d’un nouveau genre, moderne, proposant une articulation thématique, générique et chronologique inédite, enrichie d’hyperliens, de textes annexes, d’images, de musique (car les poèmes de Voltaire étaient parfois mis en musique), etc. Une telle édition doit faciliter le travail des chercheurs : Voltaire, par exemple, pratiquait volontiers l’auto-plagiat, c’est un phénomène qui n’a pas été beaucoup étudié et que les éditeurs de Kehl ont occulté, en supprimant des répétitions qu’ils trouvaient inconvenantes. Or, la redite, chez Voltaire, est une véritable esthétique, et à la fin de sa vie, il reprenait des textes de jeunesse, faisait parfois semblant d’ignorer qu’il en était lui-même l’auteur, les corrigeait, etc. Les techniques d’alignement de séquences permettent de redonner vie facilement à cet aspect de l’écriture. Le numérique doit également nous permettre de repenser des notions clefs de la pensée de Voltaire comme l’athéisme ou la tolérance, qui ont pu évoluer dans le temps, de comprendre son positionnement politique à telle ou telle période, ou les raisons de son intérêt pour la jurisprudence à la fin de sa vie. On doit pouvoir sortir de l’opposition traditionnelle un peu figée entre Voltaire et Rousseau et de la lecture monolithique proposée, par exemple, par le Dictionnaire philosophique en huit volumes de l’édition de Kehl, qui se compose de textes écrits sur quarante ou cinquante ans que Voltaire n’avait jamais pensé à regrouper.

Glenn Roe

Le label Digital Voltaire regroupe un ensemble de projets, qui ont vocation à enrichir, à terme, l’édition numérique des œuvres complètes de Voltaire. Le programme de recherche qui sera fixé courant 2019 prendra symboliquement le relais de l’édition papier. Les projets portent sur l’intertextualité, sur les autorités, sur les phénomènes de reprise, sur les principales thématiques de la pensée de Voltaire, que nous étudions en recourant à des techniques de topic modeling et de mapping. La vectorisation des mots doit nous permettre de mieux comprendre l’évolution de la pensée philosophique de Voltaire. Nous devrions parvenir à mettre au point une sorte d’ontologie ou de cartographie intellectuelle de Voltaire, qui pourra être comparée avec celle de Rousseau ou d’autres auteurs du XVIIIe siècle édités par la Voltaire Foundation.

Quelles sont les priorités de la Voltaire Foundation dans le domaine des humanités numériques ?

Nicholas Cronk

Il est certain qu’un projet numérique qui réunirait les œuvres et les correspondances de plusieurs auteurs du XVIIIe siècle, et qui ferait profiter aux chercheurs des possibilités nouvelles offertes par les outils développés au sein des humanités numériques, est loin d’être irréalisable et a de quoi séduire. Une expérience de ce genre a été réalisée sur les correspondances d’auteurs, dans les années 2000, au sein du projet Electronic Enlightenment, qui regroupe environ soixante-dix-mille lettres dans plusieurs langues. Mais je dirais que l’enjeu le plus immédiat, pour nous et pour Digital Voltaire, c’est aujourd’hui de parvenir à développer ce laboratoire de recherche en humanités numériques qui favorisera les recherches sur l’œuvre de Voltaire et sur sa réception, tout en restant l’édition critique de référence. Ce projet est un modèle de ce que nous pourrions faire à la Voltaire Foundation dans les années à venir, en collaboration avec d’autres partenaires comme la Sorbonne.

Exploring multilingual digital editions

The Taylor Institution Library recently launched a new course teaching digital editing, with students able to create digital editions in any language of their choice. I was delighted to be able to contribute by designing the accompanying website on which the texts are published:

I am the editor and developer of several academic resources, including the award-winning Eighteenth Century Poetry Archive (currently English-language poetry only) and the Thomas Gray Archive. My interest in working with multilingual materials was sparked by part of this resource: ‘Gray’s Elegy in Translation’. According to the Digital Miscellanies Index (DMI), Thomas Gray’s ‘Elegy Written in a Country-Churchyard’ (1751) is the most anthologized poem of the eighteenth century, and it is one of the most widely and frequently translated, paraphrased, and imitated poems in the English language. With to date at least 266 translations into at least forty languages, the Elegy has inspired translators ever since the earliest translations into Latin appeared in the early 1760s. Since those early translations, the Elegy has been influential in the history of many national literatures, particularly in the context of the evolution of European Romanticism.

Drawing on the extensive collection of Elegy translations compiled by Tom Turk,(1) the purpose of the project is firstly to enable the study of the evolution of translations of the poem in a single language and culture, and secondly to allow for a comparative study of the translations across languages and literatures, initially within, but ultimately beyond European boundaries. The first phase of the project covers the period up to 1805, comprising fifty-seven verse and prose translations of the Elegy in eleven languages (Danish, French, German, Italian, Latin, Polish, Portuguese, Russian, Spanish, Swedish, and Welsh). The translations variably highlight changes in the understanding and interpretation of Gray’s poem, reflect cultural borrowings and transfers, betray changes in literary taste, and may even allow us to uncover the circumstances, agency, and purpose of their production in the first place. Thanks to James D. Garrison’s outstanding work,(2) we have a sense of the national context of Gray’s significance in both France and Italy, but for many other European and particularly non-European languages, these histories remain to be written.

The two main objectives for the project website were to provide an intuitive interface to the translations that allows for easy comparison of equivalent passages and to allow users to comment on any part of the original or any of the translations. In the full-text view up to three texts (in any combination of languages) can be explored side-by-side in their entirety, ‘equivalent’ passages are highlighted when hovering over any stanza or paragraph:

In the detailed view any one stanza from any text can be compared with its ‘equivalents’ (if available) in either all of the translations or the translations in a particular language:

Users can add a translation or comment on a translation of any section of any of the texts using a simple click and drag action to mark the section to be annotated:

I would love to gain a better understanding from practitioners on which avenues to pursue (linguistic, stylistic, semantic etc.) for both the enhanced mark-up of the translations and the development of tools (and/or integration of external services, such as dictionaries/thesauri) to provide via the interface. Having caught the multilingual bug, I am also very keen to expand another resource of which I am editor, the Eighteenth Century Poetry Archive (already mentioned above), to include poems in other languages, along with tools for their analysis. Anyone reading this who might be interested in contributing to this endeavour, please get in touch!

I hope you will have a chance to explore the translations, and would love to hear about your experience with the current interface and any changes, improvements, or additions you would like to see in the future. If you can see the potential for any of the techniques mentioned to be applied in the Taylor Editions website, then I would be very happy to explore this further. Please do not hesitate to contact me with your feedback.

A born-digital edition of Voltaire’s Dialogue entre un brahmane et un jésuite

Just as the print edition of the Œuvres Complètes de Voltaire is fast approaching its completion, we at the Voltaire Foundation are starting work on two new, highly ambitious digital projects thanks to the generosity of the Andrew W. Mellon Foundation: a digital edition of Voltaire’s works based on the Œuvres complètes (Digital Voltaire), and a born-digital edition of the works of Paul-Henri Thiry d’Holbach (Digital d’Holbach).

With a view to gaining the necessary skills required to begin my work on Digital d’Holbach, in autumn 2018 I attended an intensive course on digital editions run by the Taylorian Institution Library. Taught by Emma Huber in collaboration with Frank Egerton and Johanneke Sytsema, the course takes students through all the phases of the digital edition workflow, from transcription to publication and dissemination. It is a goal-focused, hands-on course during which students are warmly encouraged to create a born-digital edition of a short text from the Taylorian’s collections.

Although short and apparently light in tone, the piece that I chose to edit – Voltaire’s Dialogue entre un brahmane et un jésuite sur la nécessité et l’enchaînement des choses – is a key text in the evolution of Voltaire’s philosophical views. As the title suggests, the Dialogue hinges on the question of determinism (or fatalisme, in eighteenth-century French parlance) and touches on such crucial notions as moral freedom, causation, and the problem of evil. It was first published anonymously in the Abeille du Parnasse of 5 February 1752, and it then went through several reprints during Voltaire’s lifetime, with very few variants.

My edition of the Dialogue is of course not meant to replace the one already available in OCV. Rather, it was conceived to meet the needs of the broader public – and more specifically those of students. A very short introduction, displayed on the right-hand side, provides essential information on the philosophical issues at stake while situating the Dialogue in relation to other key texts by Voltaire. An original translation into English by Kelsey Rubin-Detlev makes the text more widely accessible, allowing students working in fields other than modern languages (e.g. philosophy) to engage with Voltaire’s ideas. High-quality pictures of the 1756 edition, which provides the base text, aim to give non-specialists a taste of what it feels like to leaf through a (dusty) eighteenth-century book. Finally, a modernised version of the text is available next to the facsimile, and a rich corpus of annotations – displaying in both the French transcription and the English translation and featuring links to several other digital resources (the ARTFL Encyclopédie and Tout Voltaire, but also Wikipedia and BibleGateway!) – aims to render the reading experience as informative and rewarding as possible.

But there is more to this edition than first meets the eye! For example, by clicking on ‘Downloads’ in the menu bar, a fifth column will appear from which the user is invited to download pictures as well as TEI/XML files, which can then be used as models to generate further digital editions. Also, a drop-down menu in the transcription column allows users to choose between two different versions of the text in addition to the modernised version displayed by default: a diplomatic transcription of the 1756 edition and a diplomatic transcription of a 1768 edition, which comes with its own set of images that are also available for download under a Creative Commons Licence. By looking at these texts, users will get a sense of how radically French spelling evolved in the mid-eighteenth century.

Readers of this blog are most cordially invited to browse my edition. Any feedback on content or presentation (e.g. the way footnotes or variants are displayed) would be greatly appreciated as I work towards an edition of a considerably longer text by d’Holbach. But more on that in the coming months!

The Salons Project: a digital approach to eighteenth-century French salons

We are currently finalising the programme for Digitizing Enlightenment IV, a day-long workshop that will take place on 15 July as part of the ISECS Congress in Edinburgh this summer. In order to expand our network of Digitizing Enlightenment projects and researchers, we encourage those working in any aspect of digital humanities across the interdisciplinary spectrum of eighteenth-century studies to attend the event, if in Edinburgh, or contact us for more information.

Meantime below is the second post in our series of follow-up discussions based on work presented at the Digitizing Enlightenment III workshop.

– Glenn Roe, Voltaire Lab

Eighteenth-century French salons have developed a mystical aura as sites of elite sociability and (more controversially) as potential workshops of Enlightenment philosophy. They were, however, ordinary face-to-face gatherings in many ways – not unlike unscheduled conferences and meetings with loose agendas today; the one consistent difference is that they were held in private homes instead of conference rooms and organized by individuals (normally women) rather than groups or committees. The nineteenth-century term “salon” grouped together a variety of meetings with certain characteristics: salons were held in private homes with relatively elite participants, conversation was the primary activity, and they occurred on set days and at times that were part of a larger social calendar. Aside from these very general characteristics, salons had a wide variety of purposes, publics, and activities.

a French salon

Niclas Lafrensen [Nicolas Lavreince] (1737-1807), A French salon.

The most celebrated among salons, notably Tencin’s, Graffigny’s, Geoffrin’s, and Lespinasse’s, have become associated with great writers, philosophes, and mathematicians, like Voltaire and D’Alembert. Antoine Lilti has challenged the view that salons were primarily counter-cultural venues for philosophical debate, showing that the aristocratic traditions influenced notions of politesse in the salons and emphasizing the aristocratic habitus of many salon hostesses even when they had philosophes as guests. Disagreements over the character of salons may amount to differences more of degree than of type, since historians generally agree that the salons were mixed environments, but these debates do demonstrate the importance, now more than ever, of working through who was in attendance, in order to identify the social characteristics of eighteenth-century French salons.

I am the co-director with Chloe Edmondson of The Salons Project, a database of primarily eighteenth- and nineteenth-century European salon participants. We completed our pilot project of French salons from 1700 to 1800 last year and have some preliminary results, which will appear in the volume Digitizing Enlightenment, edited by Glenn Roe and Simon Burrows, in 2019. As expected, we found a great deal of evidence for social mixité in eighteenth-century salons, including patterns of mixed gender, age, occupation, interests, and social status. We also found that both women and literary figures were present in all of the major salons, including salons like Deffand’s which were not known for their openness to the philosophes. We found that nobles were present in all salons, as were gens de lettres, and that these people were often one and the same.

Our list of more than 600 salon participants is far from a complete record of eighteenth-century French salon attendees, but it is the largest and most complete database that we are aware of. The purpose of our study was not only to create a database, but also to create a method and a format for sharing data about salons and other informal networks. This method uses the robust data model created by the Electronic Enlightenment project, such that our data are compatible with the many other Enlightenment-era projects that are inspired by that database. We also use the schema “Procope”, which we developed along with Maria Teodora Comsa, Dan Edelstein, and Claude Willan to classify Early Modern European individuals, and which is described in our article “The French Enlightenment network”.

the Salons Project

Salon, correspondence, and knowledge networks in French salons, 1650 to 1815 (data from The Salons Project, Conroy and Edmondson).

Within our larger dataset (1650 to 1815), we found that the letters networks and salon networks remained well integrated, and that philosophes were a minority but well integrated into the core of the network (see diagram). The most central figures are the ones whose networks are most associated with each field of knowledge (for example, Lespinasse’s salon is strongly associated with the “Letters_Philosophical” network, whereas Praslin’s is not; Voltaire’s correspondence network is more strongly associated with the encyclopédistes than is Necker’s; the Letters networks and “Letters_Philosophical” network are themselves tightly connected and central to salon networks). Whereas the best known salons of the era were well integrated into the letters and philosophical networks, it is important to remember that many of the salon attendees were not otherwise part of the French Enlightenment network, especially women, lower-status individuals, family members of other salon participants, and foreigners. By adding these more marginal people to the records on eighteenth-century French sociability, we hope to open up new avenues for finding social relations that are not well known among these more marginal participants on the edges of the Enlightenment. Even where we were not able to learn much about some of these more minor figures, including them in this preliminary dataset increases the chances that we will learn more about them in the future.

The humanist world of Voltaire’s correspondence

We know from reading Voltaire’s letters that he likes quoting – French literature in abundance, but also a fair amount of Latin. There is often a strong sense that he is quoting from memory, which is more than likely the lasting mark of his Jesuit teachers at Louis-le-Grand, who put Latin at the centre of the curriculum. Indeed, Voltaire had the benefit of some renowned Jesuit scholars as his teachers, notably Le Père Porée, who famously taught a ‘Senecan’ prose style, and Le Père Thoulier (later the abbé d’Olivet), a distinguished Cicero scholar who remained on friendly terms with Voltaire throughout his career.

Latin verse in particular, played a preponderant role in Voltaire’s education, as poets were at the heart of college teaching, and Virgil, Ovid, and Horace were by far the big three since the 16th century at least.[1] The Jesuits taught primarily by way of daily recitals (recitatio) of verse required by all students: ‘On attachait à la recitatio une importance dont nous n’avons pas idée aujourd’hui…’ (Dainville, p.175). Thus, students at Louis-le-Grand all committed large chunks of Latin verse to memory as both a means of imitation for learning to write, and also as a method of retaining information, as Voltaire would elsewhere describe the pedagogical approach of the Jesuit Claude Buffier: ‘Il a fait servir les vers (je ne dis pas la poésie) à leur premier usage, qui était d’imprimer dans la mémoire des hommes les événements dont on voulait garder le souvenir’.[2]

Collège de Louis le Grand, circa 1789.

Collège de Louis le Grand, circa 1789.

Given this background, we aimed to examine Voltaire’s use of Latin quotations across his massive collection of correspondence, described by Christiane Mervaud as ‘perhaps his greatest masterpiece’. The Besterman edition of Voltaire’s correspondence, originally published in some 50 print volumes, and digitised in the early 2000s as part of the Electronic Enlightenment project, contains 21,256 letters of which 15,414 are written by Voltaire himself. It is astonishing, then, that this masterpiece remains relatively unstudied. Besterman identifies Latin passages when they are from the major writers (Horace, Virgil, Ovid, Lucretius) – the authors for whom there were concordances easily available in the 1950s and 1960s. In the case of lesser poets like Manilius, however, Besterman was obliged to leave the passages unannotated. These passages can now be easily identified thanks to new methods developed in the digital humanities. In particular, as part of this year’s research programme in the Voltaire Lab, we compared all of Voltaire’s letters to Latin digital sources in an effort to systematically identify all of his Latin quotations, while at the same time, as we’ll see below, exploring the social and intellectual networks over which these quotations were exchanged.

Marcu Manilius, <i>Astronomicon</i>, 1767.

Marcu Manilius, Astronomicon, 1767.

Using sequence alignment algorithms designed to identify literary text re-use at scale –developed in collaboration with the ARTFL Project at the University of Chicago – we identified some 672 Latin citations in Voltaire’s correspondence by comparing the letters to the Packard Humanities Institute’s Classical Latin Texts (PHI) digital corpus. The PHI contains essentially all Latin literary texts written before A.D. 200, as well as some texts selected from later antiquity. The resulting alignments allow us to move beyond Besterman’s ad hoc manner of identifying quotations towards a more systematic understanding of Voltaire’s use of Latin authors.

After some data pruning – the inclusion of several commentators and grammarians from Late Antiquity in the PHI dataset meant that there were some repeated matches that were spurious – we reduced our set of Latin passages to 342 citations used by Voltaire himself to his various correspondents. Here is a list of these quotations by Latin author in descending order:

Table 1. 342 individual Latin passages found in letters by Voltaire.

Table 1. 342 individual Latin passages found in letters by Voltaire.

Overwhelmingly Voltaire prefers to quote Latin poets; and that Horace, Virgil and Ovid should be the top three is hardly surprising, though the presence of Horace is dominant. There is breadth as well as depth here, and the list goes beyond the usual suspects to include minor figures such as Manilius, Statius, and Cato the Elder. Does this mean, for instance, that Voltaire is quoting someone like Manilius from memory? If so, how interesting and altogether unexpected.

The next important question we broached was concerned with the recipients of Latin passages, i.e., who are the adressees of the letters in which these Latin quotations appear? In all we found 101 different recipients of at least some Latin, out of 1,465 total recipients in Voltaire’s correspondence (roughly 14.5 %). This is quite small, as a proportion of addressees overall. So how can we gloss these names as members of a group, or network of Latin quotations?

Table 2. Addressees with more than five Latin quotations.

Table 2. Addressees with more than five Latin quotations.

Using the ‘Procope’ social network ontology of the French Enlightenment, established by Dan Edelstein et al., at Stanford,[3] we were able to automatically assign social categories to our list of addressees, which while not a perfect system, nonetheless helped us understand the fundamentally ‘elite’ status of this sub-set of Voltaire’s correspondents.

Gender is an obvious criterion that is apparently lacking: all addressees are male apart from one. Given that men learned Latin, and women didn’t, the use of Latin quotations is self-evidently gendered in this case. This is further reinforced by the manner in which Voltaire uses two verses by Virgil with La Duchesse de Choiseul, his one female addressee, in a letter from 1771:

‘Pour moi, Madame, qui les aime passionément je vous dirai
Ante leves ergo pascentur in æthere cervi
Quam nostro illius labatur pectore vultus.’

‘Vous entendez le latin, Madame, vous savez ce que celà veut dire:
Les cerfs iront paître dans l’air avant que j’oublie son visage.’

After quoting the two lines from the Bucolics, Voltaire goes on to translate them for Madame de Choiseul, even though she can presumably understand the Latin – a case of early-modern ‘mansplaining’ in action.

Within the group of 101 addressees, there is a clearly-defined social group of old, close friends from school (those with whom he had learned Latin), as well as an overlapping sub-group in Normandy, or in one case from Voltaire’s early law career:

Addressees from Louis-le-Grand, where Voltaire learned Latin:

  • The Marquis d’Argenson (later foreign minister)
  • The Comte d’Argenson (later war minister)
  • The Duc de Richelieu (soldier and leading courtier)
  • The Comte d’Argental, conseiller au parlement de Paris
  • Pierre-Robert Le Cornier de Cideville, conseiller au parlement de Rouen

Other old friends from the overlapping Normandy/law group:

  • Formont, a wealthy, talented light poet who was also friends with Cideville.
  • Theriot, a an early friend of Voltaire’s, from when they were both young apprentice lawyers, who was also friends with Formont and Cideville.

Otherwise, we find many cultivated acquaintances in this list who are themselves authors: Frederick, Algarotti, D’Alembert, etc.; along with one of Voltaire’s teachers from Louis-le-Grand: d’Olivet, translator of Cicero and Desmosthenes into French, elected to the Académie in 1723. Clearly, Voltaire’s use of Latin was a means of determining readership. By constructing an epistolary community with selected groups of correspondents, Voltaire underscored their shared experiences and humanist culture.

But, to what extent was this sort of cultural exchange reciprocal? I.e., if Voltaire writes to you quoting Latin poets, do you feel obliged to respond in kind? What does it mean, for instance, that Voltaire uses Latin in so many letters to Frederick, and yet the prince never once uses Latin in return? Socially, the 41 respondents identified belong by-and-large to the same ‘elite’ categories of government or aristocracy, although there is a markedly greater presence of hommes de lettres (an ‘intellectual network’ that overlaps with the ‘social networks’ drawn from Procope) in this second list. See Table 3.

These are just some of the preliminary results we have begun to process in the context of a larger project on Voltaire’s culture of text re-use (including his penchant for ‘self-plagiarism’). As with most digital humanities projects, initial computational analyses don’t always produce ‘clean’ results, or cut-and-dried interpretations: some of the results have to be examined carefully, and some – as was the case for the grammarians and commentators mentioned above – will prove spurious or misleading. One begins asking one set of questions – can we identify Voltaire’s use of Latin and verify Besterman’s attributions – and end up with new ones: e.g., with whom did Voltaire use Latin, and how? Equally, we could extend these questions by examining other literary quotations, e.g., from French or Italian authors and by including other correspondence collections, comparing Diderot and Rousseau’s use of Latin, for instance, to that of Voltaire.

Ideally, this sort of experimental research approach also generates new research questions, ones that would have been difficult to frame outside of the digital environment. In this case, we were quickly confronted with the notion of what constitutes an instance of ‘re-use’ as opposed to an allusion or more oblique cultural reference. For example, our algorithm identified this passage from Cicero’s epistles:

‘Vale. CICERO BASILO S. Tibi gratulor, mihi gaudeo. te amo, tua tueor. a te amari et quid agas quidque agatur certior fieri volo…’

as a potential re-use employed by Voltaire in a letter to Marmontel from 1749:

‘Si vous recevez ma lettre ce soir, vous pourrez m’envoyer votre poulet pour m. de Richelieu, que je ferai partir sur le champ. Te amo, tua tueor, te diligo, te plurimum, &c.’ [5]

Is this re-use or not? Besterman makes no mention of Cicero in his annotation, but rather places this passage into a more generic class of ‘Roman epistolary formulas’. But perhaps there is more going on here; perhaps the model of Cicero’s epistles – central to the Jesuit syllabus – remains at the forefront of Voltaire’s mind when he himself is in the act of letter-writing. With the sorts of addressees for whom Voltaire uses Latin quotations he may likewise use a Ciceronian subscription. Here the Ciceronian model shapes Voltaire’s epistolary rhetoric.

Finally, pushing this line of enquiry a bit further, we came across another discovery: there are reduced versions of the passage, “Vale. Te amo”, which Voltaire uses extensively in the correspondence, and in particular with the social network of old school friends outlined above. This passage is in fact too small to be identified by our matching algorithms, and we would furthermore be a bit hard-pressed to classify it as a singularly Ciceronian borrowing. And yet…
