The ways in which scholars research the iconographic traditions of the Middle Ages is continuously evolving. In order to address this, the Index of Medieval Art organized and sponsored a roundtable, Encountering Medieval Iconography in the Twenty-First Century: Scholarship, Social Media, and Digital Methods, at the 54th International Congress on Medieval Studies at Western Michigan University in Kalamazoo. The five panelists briefly presented on the ways in which they incorporated iconography into their teaching, research, and curatorial work. They then participated in a discussion of how they use and develop online resources, such as image databases, to reach students and researchers. The result was a lively dialogue about how digital approaches can make medieval iconographic study more accessible to a diverse, global audience.
One of the first topics of discussion was the avenues by which viewers encounter medieval iconography in the twenty-first century. Anne Stanton, Associate Professor of Art History at the University of Missouri, raised the point that popular social media outlets and online databases are often the first portals through which many students gain access to medieval images and learn about subject matter in works of art. Many institutions have responded to this this fact by using social media platforms to broaden interest in iconography and connect users to works of art. The many vibrant examples of social media use in the field, ranging from museums to libraries, include the Getty, Dumbarton Oaks, and the British Library. Sabine Maffre, Curator of the Mandragore Database at the National Library of France, discussed developments at the library’s blog Gallica, which has been inviting professional bloggers to write posts about illuminations in order to diversify their audience and make their medieval image collections more visible.
Beyond questions of access, another change has occurred in the ways in which we think about iconography. Konstantina Karterouli, postdoctoral fellow and graduate of Harvard University, presented an Artificial Intelligence (AI) project that the Dumbarton Oaks Research Library & Collection is developing with the goal of teaching computers to recognize the different architectural elements of a medieval building. Commenting on the wider potential of this approach, Maffre also noted that the Bibliothèque nationale de France (BnF) staff have been working toward implementing automatic recognition of manuscript illuminations through AI. A contrasting approach to iconography, presented by Isabelle Marchesin of the Institut national d’histoire de l’art (INHA) at the Sorbonne in Paris, faces head-on the problem of offering something that AI still cannot provide: interpretations of specialized content. The OMCI (Ontology of Medieval Christianity in Images) project, founded and developed by Marchesin, is based on the concept that, beyond narrative and portraits, Christian medieval images implicitly refer to another level of signification that is ontological and strongly connected in this case to theology as a holistic system of explanation of the world.
One important takeaway from the roundtable was the recognition that the role of the iconographer itself is changing. As Professor Marina Vicelja of the University of Rijeka emphasized, rather than requiring the solitary work so often undertaken in the past, it could and should be seen in light of collaborations, interdisciplinary research, and international networks. A starting point could be the implementation of cross-discoverable databases, shared standardized vocabularies, and the use of platforms like Biblissima, a digital library and widely interoperable data cluster designed to gather and give access to the main iconographic and textual databases. These ideas inspired discussion of the difficult balance between the strategies used by database specialists and the kinds of usability expected by twenty-first century researchers. Karterouli strongly emphasized the importance of standardization in these endeavors to help retrieve information, and Vicelja stressed the necessity of integrating metadata in order to avoid misunderstandings.
In the twenty-first century, we find ourselves at a crossroads between traditional methods of iconographic study and the implementation of pioneering technologies such as AI. The potential for interoperable platforms to enhance the research experience could answer new expectations with new possibilities. While it can be difficult to strike a balance between time-tested approaches and new ideas, the tension is proof that the study of iconography is very much alive and evolving. We hope that the Index roundtable at Kalamazoo was only the first word in a vibrant and expansive dialogue among an international community of creators and consumers of information about medieval iconography.
Please join the Index of Medieval Art for a one-day conference that examines the role of the visual in the negotiation of medieval power relationships, whether political, social, religious, or individual. Eight scholars with a range of specializations will address how works of medieval art were used to impose and maintain power over others, to resist dominant figures or regimes, or as agents in the back-and-forth of an ongoing power struggle. Speakers will include:
Heather Badamo, University of
California, Santa Barbara
Elena Boeck, DePaul University
Thomas E.A. Dale, University
Martha Easton, St. Joseph’s
Eliza Garrison, Middlebury
Anne D. Hedeman, University
Tom Nickson, Courtauld Institute of Art
Avinoam Shalem, Columbia University
A schedule and free registration link will be posted in late summer 2019
Organized by Elina Gertsman and Vincent Debiais and hosted at the Index of Medieval Art
Focusing on the long and rich tradition of nonfigurative art, this international symposium will explore the inception and transformation of abstraction(s) at various historical pivot points between the advent of Christianity and the interrogation of epistemological queries in the later Middle Ages. The symposium aims to introduce the concept of abstraction to the field of premodern art and redefine it as a visual structure that predicates the very nature of image-making. We seek to interrogate non-figurative forms in medieval material culture; to contextualize these forms within the contemporaneous cultural and philosophical discourses; to identify the common features that favor the emergence of abstraction specifically in the long Middle Ages; and to determine how abstraction has been used to make visible what is beyond any kind of representation.

The conference is co-sponsored by the Samuel H. Kress Foundation, the French-American Cultural Exchange Foundation, the Index of Medieval Art, Case Western Reserve University, and the École des hautes études en sciences sociales.
Eclecticism at the Edges: Medieval Art and Architecture at the Crossroads of the Latin, Greek, and Slavic Cultural Spheres c.1300–c.1550
On April 5-6, 2019, the Index will co-host “Eclecticism at the Edges: Medieval Art and Architecture at the Crossroads of the Latin, Greek, and Slavic Cultural Spheres,” along with the Princeton Institute for International and Regional Studies, the Department of Art & Archaeology at Princeton University, The Seeger Center for Hellenic Studies with the support of the Stanley J. Seeger Hellenic Fund, the Mary Jaharis Center for Byzantine Art and Culture, the International Center of Medieval Art, and the Society of Historians of East European, Eurasian, and Russian Art and Architecture. This two-day symposium focuses on the art, history, and culture of Eastern Europe between the 14th and the 16th centuries .
In response to the global turn in art history and medieval studies, “Eclecticism at the Edges” explores the temporal and geographic parameters of the study of medieval art, seeking to challenge the ways in which we think about the artistic production of Eastern Europe from the fourteenth through the sixteenth centuries. This event will serve as a long-awaited platform to examine, discuss, and focus on the eclectic visual cultures of the Balkan Peninsula and the Carpathian Mountains, the specificities, but also the shared cultural heritage of these regions. It will raise issues of cultural contact, transmission, and appropriation of western medieval and Byzantine artistic and cultural traditions in eastern European centers, and consider how this heritage was deployed to shape notions of identity and visual rhetoric in these regions that formed a cultural landscape beyond medieval, Byzantine, and modern borders.
From time to time, we Indexers like to lift the veil, so to speak, on the cataloguing procedures and upgrades that we have undertaken online. One of our current priorities is filling out our Subject Authority records. These records are where researchers can find further information about a given iconographic subject, including the preferred term used by the Index for that subject and a brief description of the iconography, its main attributes, and its relevant cultural details.
We know that visitors to the database may use alternate names, spellings, or related terms for a particular subject during a search query, and we’re determined to help you find them. As we Indexers like to joke, one scholar’s Maiestas Domini is another scholar’s Christ in Majesty! (rim shot) It is for this reason that we supply a field for “See-From” terms, a list of alternate names and phrases that will redirect you to the preferred Index iconographic term.
Below is a sampling of our newest subject authority terms offered as an overview of our work methods, as well as a sense of where our field is heading with regard to iconography.

* Note from the Editors: Given our reputation as a family-friendly blog, we have decided to redact this particular authority record. To that end, we have dusted off the Index’s trusty early twentieth-century subject heading “Scene, Obscaena.” As you readers are well aware, Latin makes everything sound more modest. The cataloguer responsible has been sacked.
Angels often function as messengers of God in the Bible. Perhaps the best-known example of this is Gabriel’s role in the Annunciation, a subject catalogued over two thousand times in the Index. He is identified by name in Luke 1:19, which describes him as saying “I am Gabriel, who stands before God…” as he brings word to the Virgin Mary that she will bear the son of God.
The story of the Annunciation and Gabriel’s part in it appears in the gospel of Luke 1:26–38. It recounts how God sent Gabriel to Nazareth to the home of the Virgin Mary. There, the archangel announced “Hail, full of grace, the Lord is with you: blessed are you among women” (Ave gratia plena; Dominus tecum; benedicta tu in mulieribus) found in verse 28. The reason for this greeting appears a few lines later in verse 31: “…for you have found grace with God. Behold you shall conceive in your womb, and shall bring forth a son….” In verse 35 Mary, as yet unmarried, learns how this will come about: “The Holy Ghost shall come upon you, and the power of the Most High shall overshadow you.”
Throughout the Middle Ages, the Annunciation was depicted with varying degrees of complexity, and the means by which Gabriel brings his news varies as well. On the central portal of the Reims cathedral west façade (1245–1255), two statues of Gabriel and Mary stand next to each other, Gabriel smiling happily, Mary pensive. Here Gabriel offers nothing beyond a cheery expression, and very probably a gesture of blessing with his now-missing right hand. Yet the story was familiar enough that the two principals in close proximity would have triggered the memory of the Annunciation story for the viewer.
In the slightly more elaborate scene from a sixteenth-century Gradual in Princeton University Library (Princeton 11, fol. 2r), Gabriel approaches from the left, with his right hand holding a scepter, a reference to kingship, and with his left hand indicating the dove of the Holy Spirit hovering above Mary’s head. No words are exchanged. Gabriel’s verbal message is implied by his symbolic scepter and gesture.
Gabriel’s message is more overt in a highly detailed Annunciation image in an elegant fifteenth-century Book of Hours in the Morgan Library (M.893, fol.12r). The Trinity is present—God appears in a foliate medallion at the upper left, generating rays on which a mini Christ Child, carrying a wooden tau cross, glides downward. At the end of the rays, the Holy Spirit, again in the form of a dove, approaches Mary’s head. She observes this scene with some trepidation, raising her left hand as if to stop all this activity. At left, Gabriel holds a scroll inscribed Ave gratia plena dominus tecum benedicta tu in meenlieribus (sic). Mary is kneeling at a draped prie-dieu, her right hand resting on an open book lying on a pillow, emphasizing her piety, while at right in a niche is a vase with a stem of lilies evoking her purity. The plethora of symbolic forms suggest that the message is being fulfilled at the same time as Gabriel is delivering it, even as Mary’s raised hand says “I am not worthy.”
Gabriel bears his message in an unusual and possibly unique way in the Morgan Library copy of the Concordantiae caritatis (M.1045, fol. 7v). The text of this manuscript was originally written by Ulrich von Lilienfeld, a Cistercian monk in Lilienfeld, Austria, sometime between 1351 and his death in 1358. It is a typological text relating saints’ lives, Old and New Testament topics, and moralizing texts about nature. The manuscript provides sermon material, and is arranged in the order of the church year. The Morgan copy was written and illuminated in Austria in the third quarter of the fifteenth century.
In the Concordantiae
Annunciation, the Virgin Mary appears to be kneeling, holding an open book with
both hands. A dove descends toward her head as she looks back over her left
shoulder. Her gaze is directed toward Gabriel, who kneels, both hands extending
a partly folded document bearing three columns of pseudo-writing and three
seals hanging from its lower edge. Why is Gabriel shown with this very unusual
The answer may lie in the special format of Gabriel’s document, which resembles that of legal documents in the Middle Ages. The agreement was written on the page itself, while seals appended to the bottom served as the signatures of the parties involved in the contract. The number of seals depended on the number of individuals taking part. Since three seals appear here, it is not a great leap to imagine them representing the Trinity—Father, Son, and Holy Spirit. Is Gabriel delivering a signed contract to Mary, with the particulars outlined in three columns above the seals? Exceeding the traditional verbal greeting with which he communicates that Mary will become the mother of God, Gabriel here delivers a hard copy of a binding compact, leaving her no option but to accept.
When the Index of Medieval Art launched its new online database application in 2017, we were excited that its modernized, user-friendly design would make our data more accessible to both experienced and neophyte researchers. We hoped also that moving to a proprietary, cloud-based design would lower operating costs, making the Index more financially accessible as well. And indeed it did: in our first year, we were able provisionally to lower institutional and individual subscription fees by one third and have seen subscription numbers rise as a result.
We’re now delighted to announce that as of July 1, 2019, we’ll be able not just to let the new rates stand, but to lower both subscription fees further by another $100, setting institutional fees at $850 and individual fees at $250 per annum. We hope that this further reduction, while modest, helps to bring the resources of the Index within reach for more researchers at a time of increased financial pressure on humanities scholars globally.
King David is well represented in the Index of Medieval Art database, with close to 200 subject headings covering the various scenes of his life. He is most often depicted as a richly garmented king, often with his role as the psalmist suggested by his signature harp and crown. One variant of his iconography, which I encountered while cataloguing a historiated initial from an early sixteenth-century French Psalter, presents a familiar subject in the life of David, described by the Index as David, Communicating with God (Fig. 1). However, in this example, the kneeling David adds an extra gesture to his prayer routine. Where one would expect to find reverent folded hands, David emphatically points his finger to his protruding tongue!
While studying this initial, I decided to use the tools in
the updated Index database to explore how David’s pose and the purposeful indication
of his tongue were related to the psalm verse. In this Psalter, the initial D
for Dixi begins Vulgate Psalm 38, verse
2: Dixi custodiam vias meas; locutus sum
in lingua mea posuri ori meo custodiam cum consisteret peccator adversum me…
(Douay-Rheims Bible, accessed 22 February 2019, http://drbo.org/). Translated, this
reads “I will take heed to my ways, that I sin not with my tongue. I have set guard to my mouth, when the sinner
stood against me.” The tongue is mentioned one more time in this psalm
at verse 5 with regard to speech, “I spoke with my tongue: O Lord, make me know
my end. And what is the number of my days: that I may know what is wanting of
me” (drbo.org). The image of David thus prefigures the textual passages of the psalm
in that both image and text suggest the speaking and offending capabilities of
the tongue. But, how often do we see David depicted with his tongue sticking
out? And can we find other contexts for his expressive gesture?
I entered a simple keyword search for “tongue” in the upper
right search bar on the Index database homepage and used
the Subject Filter to refine my results to David,
Communicating with God. Immediately, I located a much earlier scene from a
Parisian Bible in the Morgan Library dated to the first quarter of the
thirteenth century (Fig. 2). This initial D, also beginning Psalm 38, encloses
a beardless, crowned David, looking up toward the face of God and mirroring the
action of raised finger to outstretched tongue.
Since both of these images open Psalm 38, the presence of
magnified tongues seems intended to show that significant body part that David was
obliged to “sin not” with.
This connotation of the image is better understood in the context
of the medieval preoccupation with the peccata
linguae, or “sins of the tongue,” such as those assigned to fallen
characters in the Divine Comedy and
the Roman de la Rose. These
transgressions of speech include flattery, duplicity, evil counsel, discord,
and blasphemy. Medieval moralists also were concerned with sinful tongues: the
Franciscan John of Wales (d. 1285), for example, wrote a preaching treatise called
De Lingua (“The Tongue”), which
outlined the proper duties of a “good” tongue as to share in ethical knowledge
and to oppose its own natural “bad” inclinations.
In medieval art, depictions of sinful tongues like David’s can be found in figural representations of Slander, False Seeming, and other personifications of vice. A figure identified as the Unmerciful Judge sticks out his tongue in the lower margin of a 15th century Manuel des Péchés to illustrate the Exemplum, or lesson, for the Sins of Avarice and Covetousness (Fig. 3). His long, curled tongue and raised hands suggest how insistently he imparts this lesson on the vices. However, his prominent tongue is also inherently tied to his cruel speech, offering a visual metaphor of merciless judgment.
Wishing to investigate further the iconography associated
with Psalm 38, I used the Index database to browse through the numbered psalms
in the Subject Browse
List. Clicking the subject heading for Psalm 039 (Vulg., 038) revealed that a majority of the
illustrations depict David pointing to his mouth, a common way to represent
speech, but without his tongue sticking out. One such initial appears in the Noyon
Psalter, attributed to the Master of the Ingeborg Psalter, in the J.
Paul Getty Museum (MS. 66, fol. 41v). This suggests that the literal
representations of David’s tongue were the more unusual depiction. To take this
theory a step further, I repeated the keyword search for “mouth” and refined
the subject to David, Communicating with
God. This search yielded about 30 examples where David was indicating his
closed mouth, a subject that is particularly common in manuscript initials
associated with Psalm 38.
Medieval commentaries on Psalm 38 help to explain the popularity of this iconography. Theodoret’s Commentary on Psalm 38 notes the text’s emphasis on the sinfulness and “lowliness” of human nature and humanity’s need for deliverance, while Augustine wrote of the same psalm that, although the tongue was “prone to slip,” bridling it will help one stand against wicked enemies. Both commentators connected Psalm 38 to an episode in Samuel, where David was viciously pursued by Absalom and abused by Shimei, who threw sticks and stones at him while he fled from Jerusalem. That biblical narrative itself is sometimes found illustrating Psalm 38 (see the related Index subject heading David, Cursed by Shimei). In a manuscript of the Enarrationes in Psalmos, dating to the mid twelfth century, a historiated initial P encloses a crowned David covering his mouth while Shimei hurls stones at him (Fig. 4). Here, David’s cautious gesture and muted tongue show his restraint from sin, shedding light on the meaning of the gesture when it appears in the psalm initials.
Finally, I decided to broaden my search to locate all depictions of this particular body part with David. I repeated the keyword search for “tongue” and set the Subject Filter to David. This led me to a historiated initial in the twelfth century English manuscript of the Saint Albans Psalter and to another layer of iconographic context. Here, the initial E for Erucatavit, beginning Vulgate Psalm 44, encloses a seated and crowned David, who raises a pen in his right hand and with his left index finger points to his extended tongue (Fig. 5). Written in red ink above the incipit is the rubric Lingua me calamus scribae, taken from verse 2 of that Psalm, which can be translated as, “My tongue is the pen of a scrivener”(drbo.org). This verse of Psalm 44 is preceded by the mention of David’s verbum bonum, or the “good word” uttered from his heart to the king (mea regi), suggesting that goodness issues from him and through him, by way of tongue and pen.
With regard to this Vulgate Psalm 44, Augustine comments,
What likeness, my brethren, what likeness, I ask, has the “tongue” of God with a transcriber’s pen? What resemblance has “the rock” to Christ? (1 Corinthians 10:4) What likeness does the “lamb” bear to our Saviour (John 1:29), or what “the lion” to the strength of the Only-Begotten? (Revelation 5:5)
(Augustine, Expositions, Digital Psalms version, p. 264)
Today, we enjoy ample use of emojis, which add expressive
meaning to our messages to one another. In the Middle Ages, manuscript
illuminators did not miss the opportunity to illustrate textual passages with similarly
expressive visual cues in images, which also linked to the complex layers of
meaning readers anticipated finding in the psalms. Although David’s gesture to
his closed mouth seems to be a relatively common composition, the emphasis on
his stuck-out tongue in certain depictions speaks just as expressively of its
sinful capabilities as it does of its usefulness as an obedient tool.
The investigation of David’s “emoji” highlights how researchers can look for specific iconographic motifs in the Index by combining keyword searches in the description field and filtering with controlled headings in Advanced Search options. For advice on your own research topic and forming search strategies using the Index database, send us a Research Inquiry. We’ll be 🙂 to hear from you!
