The Index of Medieval Art was delighted to offer its second Wintersession, “Exploring and Creating a Byzantine Icon: Then and Now,” on January 23rd, 2024. Its fifteen participants included Princeton staff, faculty, undergraduate and graduate students. In the first part of the workshop, they learned about the history and creation of Byzantine icons. In the second, they had the opportunity to create their own icons using modern artistic materials. 

Index Art History Specialists Maria Alessia Rossi and Jessica Savage led the workshop, opening with a presentation on the Index resources and delving into some questions about iconography using large reproductions of the icons from Mount Sinai, generously loaned by Visual Resources, as a basis. The group discussed the iconographic details in works of art, exploring the subject matter in icons that generate tags in the Index database. Jessica invited the students to observe the figures and scene in a twelfth-century Sinai icon of the Annunciation (Index system no. 57527), looking for major and minor details in the painting, as small as an octopus swimming underwater. Alessia introduced participants to the way Byzantine icons were displayed and their devotional practices by examining a folio from the Hamilton Greek Psalter (Index system no. 103381).

The first guest lecturer, local icon painter Maureen McCormick, showed the participants how to make the binder for egg tempera paint by mixing egg yolk and … No, not water … rather, white wine! Maureen showed the class all the tricks of the icon painter, including where to buy authentic pigments, how to grind them, and how to literally use one’s breath to “blow” gold leaf onto a red clay bole sample, which formed the nimbus of a saint. A short Instagram reel was made by Kirstin Ohrt, Communications Specialist in the Department of Art & Archaeology, to show Maureen’s breathtaking lesson in action, and you can check it out here: https://www.instagram.com/artandarchaeologyprinceton/reel/C2ud3gZLAJW/.

The afternoon session was led by Department of Art & Archaeology graduate student and icon painter, Megan Coates, who spoke about her own work with icons, as well as their importance for memory and communication. As part of an organized hands-on activity, participants created their own Byzantine icons using templates designed by Megan or choosing their own models from books or memory. Acrylic paint, brushes, drawing materials, gessoed panels, as well as gold and silver leaf materials were supplied by the Princeton Office of Campus Engagement. The outcomes were astonishing! 

About fifteen students surround a long table covered in art supplies, and each student holds up a small panel containing their artwork and icon painting.

It was a pleasure to observe the participant’s ideas and skillful process unfold as they engaged in the long-treasured art of icon-making. One participant Sigrid Adriaenssens, Professor of Civil and Environmental Engineering, wrote to us after Wintersession and said, “Thank you so much for organizing this workshop. It opened a whole new world to me that I didn’t know existed at Princeton. I really enjoyed learning about the Index, icons, and how they are made. The speakers Maureen and Megan were also very interesting and exciting to listen to!” Another participant, Zi (Zoe) Wang, visiting doctoral candidate and researcher at Princeton from the Central Academy of Fine Arts in Beijing, said she felt transported by the instrumental music we played during the hands-on activity. Zoe said about the experience, it was like “immersing myself in meditation.” We couldn’t agree more!

Are you interested in learning more and researching icons at the Index? Here are some general tips for starting an Index search about Byzantine icons, especially if you do not know exactly which icon you are looking for! 

However, these results might be too broad, so if you want to refine them you can keyword search the word “Byzantine” on the upper right search window of the database, and then filter by these other controlled terms we just mentioned, such as Work of Art Type “panel” or Medium “wood.” But if you want even narrower results, or if you know the iconography you are interested in, such as the iconography of an angel, or searching for angels by name, as in the case with the Annunciation image, you can filter by the Subject “Gabriel the Archangel.” 

If you have any questions about starting research with the Index resources, fill out our inquiry form and we will be in touch: https://ima.princeton.edu/research-inquiries/.

Finally, this Wintersession workshop could not have been possible without the generous support of the Princeton Office of Campus Engagement, the Department of Art & Archaeology, and the Index of Medieval Art. Thank you to all who helped plan and participated in this event!

Index “Gold Glass” Backfiles Status Update: Complete!

As editorial staff at the Index continue cataloging our physical backfiles, which contain over 200,000 photographs of works of art in sixteen media categories, we are happy to announce that at last, all our print records of gold glass objects have been fully digitized in the Index database! In gold glass, an image in gold leaf is fused between layers of glass. Gold glass was a favored art form in Hellenistic Greece and during the Roman period, often decorating the bases of feasting vessels, such as bowls, cups, and plates, with hidden pictures that would slowly be revealed during the consumption of food and wine. The newly digitized “Gold Glass” backfiles document over 650 objects from about 60 locations. Most examples are identified as vessels, medallions, or plaques (Fig. 1).

The glittering portraits on these glass objects, now mostly fragmentary, are usually bust length and often show whole families. These are classified under the Index subject “Family Group,” while the subject “Married Pair” is used for images depicting a bride and groom, sometimes crowned by Christ. Gold glass objects are frequently associated with marriage celebrations, and several pieces retain the names of the men and women depicted with inscriptions of good wishes. Frequently, this inscription is the Latin drinking toast “PIE ZESES” (“Drink to live,”), either in full or abbreviated, although a fourth-century gold glass fragment from Rome, now in the British Museum, bears the more sentimental words “DVLCIS ANIMA VIVAS” (“Sweet soul, may you live [long]”) around the heads of the newlyweds (Fig. 2).

Several gold glass objects contain other paired figures, especially Peter and Paul the Apostles, as the patron saints of Rome, and Adam and Eve, commonly represented in the Fall of Man­ scene. Old Testament narratives and figures, such as Moses, Abraham, Daniel, and Jonah were popular, and Christian miracles were also frequently depicted on vessels. The Index database contains just over fifty miracle scenes executed in the gold glass medium, including the Raising of Lazarus, the Miracle of Loaves, and the Wedding at Cana, suggesting that healing themes held some favor among patrons. The objects may also have served a commemorative function.

Some surviving gold glass objects contain Jewish iconographic motifs, including the Temple implements, such as the menorah, shofar, etrog, and Torah Ark. These implements can be found in the Index database by browsing the Subject list, or by searching for “gold glass” as a term and filtering by the Style/Culture “Jewish.” Mythological figures and narratives from the classical world were also favored subjects to depict on gold glass vessels. The Herculean labors, sea-nymphs, and cupids can be identified on some fragments. Other well-represented motifs in the medium include the “Good Shepherd,” which has iconographic connections to the ancient Greek ram-bearing cult figure Kriophoros. There remains much to discover and assess about images in gold glass and their meanings, production, and patronage throughout the late antique, Roman, and Byzantine periods, making the Index an essential study tool. Now, with increased access, more researchers can learn how this rather fragile art form documents fashion, commerce, rituals, and historical names and epigraphs from ancient daily life (Fig. 3).

The Index gold glass backfiles received significant attention by Ryan Gerber, our 2019 summer intern from the Rutgers School of Communication, who is now a Marquand Art Library Collections Specialist. Gerber inventoried the collection and wrote about his impressions in a blog post called “A Face in Gold Glass.” After Henry D. Schilb, Index Art History Specialist in Byzantine Art, finished adding the collection with the help of Gerber’s inventory, he noted that many gold glass objects recorded in major nineteenth century catalogs did not survive into the modern era. Thus, the publications that earlier Index catalogers used in their research may have contained the last known record of an object’s existence. Schilb said, “it was surprising to learn that many of the gold glass objects entered into the Index files have been lost to time, and at least one of them was apparently reduced to dust in the collection where it was last recorded. Not surprisingly, we have also simply lost track of several examples that were originally cataloged by Indexers before the Second World War.” With too little information to go on, the Index cataloger can sometimes upload only a drawing from the catalog and record only a “Last Known Location” for objects presumed lost to history. When we just don’t know where something is, we indicate this in the database by giving “Unknown” as the current location with a “Last Known Location” to identify the place where an item was last known to exist. This can apply to items that we know to have been destroyed, but it also applies frequently to items that are either simply lost or are now in unidentified, private collections. Although the Index can sometimes discover an object’s true current location, that bit of data can sometimes elude us, so we always welcome intelligence from anyone who might have a good lead!

It is a great achievement when we can complete an entire category in the backfiles with newly researched information, including updated location names, fuller iconographic descriptions, and new or updated terms from Index vocabularies to expand the findability of work of art records. We ought to be clear, however, that we do not claim to have recorded every known example of any medium or type of object. That must remain an ongoing project. Nevertheless, the whole Index team is thrilled to make the gold glass corpus of the original Index card catalog fully available in the database. If you want to see for yourself, you can browse “gold glass” records by Medium more fully here: https://theindex.princeton.edu/s/list/ListMediums.action. You can also reach out to us with any inquiry here: https://ima.princeton.edu/research-inquiries/. Please let us know how the Index can improve the records we have, or find out how the Index can serve your own research needs.

Cheers!

Remote Desktops

As the fall 2020 semester begins and the Index staff continue to work remotely, each of us connecting from different locations, our home libraries and desks have become essential tools in our research. They call to mind medieval images in which the scribe’s desk and well-stacked bookshelves are familiar iconographic attributes of the Evangelists, as well as theologians, scholars, physicians, and literati, as they labored in their study spaces (see Index subjects: Bookcase, Scholar, Physician, Literatus, and Philosopher Type). Their desks took a variety of forms and shapes, from tall book stands or lecterns, sometimes decorated with animals, birds, and foliage, to round or squat tables of a simpler design. Medieval images of scribes and writers often show the surfaces of their desks covered with open books or sheets, some with scrawled lines (search Index keyword: pseudo-inscriptions), inkhorns and inkpots, knives, pen cases, and a spare stylus or two.

Working in a modern study space, many of these similar tools are within my reach: pens, scissors, a pencil cup, and plenty of Post-it Notes containing my jotted reminders—arguably legible! My computer desktop is a hub for images of medieval works of art, articles, and spreadsheets that help organize my Index work. To the right of me, sits a modest collection of tomes (to name a few, Emile Mâle’s Religious Art in France: The Late Middle Ages; Roger Wieck’s Painted Prayers: The Book of Hours in Medieval and Renaissance Art; Baxter’s Bestiaries and Their Users in the Middle Ages, and the catalogues The Splendor of the Word and The Golden Age of Ivory Gothic Carvings in North American Collections). Some books are my own and some are out on temporary loan from the Index’s research library and from Firestone Library, but all are bolstering this new environment of cataloguing and scholarship from home.

For Index research staff, this means that our working desktops (both physical and virtual) and our carefully curated home libraries (whether lining our walls or nested digitally into desktop folders) will support our ongoing remote activities. This semester, we will continue to pursue new art historical research for additions to the database, including works from the original print backfiles, from monumental mosaics to illuminated manuscripts and ivory objects. We remain focused on expanding the Index collection to present the rich array of iconography from the global Middle Ages. We will also continue to refine the database by building and improving work of art location authorities, further developing Index subject classifications that improve thematic browsing, and implementing the new hierarchical browse tool for researching the placement of medieval iconography within structures. Above all, we will remain available to support researchers at all levels in their use of the online Index database.

Wherever you may be this term—whether you feel like a monk in a cell or a monkey with an inkpot—we hope that you are well and looking forward to your study, surrounded by the tools of your scholarship. We look forward to hearing how we can help serve your research and teaching in the upcoming academic year.

Exploring the Photographic Archive of the Index: Part 1

This summer The Index of Medieval Art welcomed two students from the Master of Information program at Rutgers University to inventory the Index’s photographic archive. Comprising nearly two hundred thousand cards in sixteen different medium categories, this historic image collection provides researchers a rich resource of sometimes rare visual references for the study of art produced throughout the Middle Ages. The inventories undertaken by Ryan Gerber and Michele Mesi have illuminated the extent of the archive and helped to assess the image and cataloguing needs for ongoing research and cataloguing at the Index. In this special two-part blog post, we are pleased to present their observations and accounts of their experiences.


It is a testament to the Index’s stimulating power that, despite my lack of an art-historical background, I found myself entranced by the system of cataloguing medieval iconography that the Index pioneered and is still practicing to this day. Its vision of greater accessibility through complete digitization represents another milestone in its long history, and one which will be a gift to scholars of all persuasions and experience levels.

A system largely developed by Index director Helen Woodruff in the 1930s, the photographic archive is organized in the first place by medium, then by location, object type, and the numeric order within that group. Unique codes on the left-hand corner of every index card in the catalogue represent each of these levels of organization. The fruits of this labor are hard to miss after spending any time with the Index and its elegantly interwoven subject index and photographic archive, where one can move seamlessly from subject description to pictorial representations and vice versa.

This work has also left behind a trove of archival resources such as hundreds of rolls of film and the so-called “Black Books” that were used to track the negative numbers. Each of the medium categories I inventoried not only laid the groundwork for further analysis of the collection as a whole, but highlighted the Index’s remarkable century-old ability to generate new curiosities and paths of inquiry.

Terracotta, Temporary Cards, Lamps, and Lions

Fig. 1. Terracotta lamp stamped with a lion and tree motif, 4th–7th centuries. Athens, Benaki Museum (GE 11992).

Under the medium “Terra Cotta”—a mixture of clay and water that is formed and baked or fired—the Index records more than twenty-five hundred objects across 196 locations. Of these objects, about sixty-five percent of them are oil lamps. The inventory of these files revealed some of the more common iconographic motifs found on terracotta objects, which include foliate ornament, a variety of land animals and birds, symbols such as crosses, as well as inscriptions and monograms. One terracotta lamp from the Benaki Museum in Athens depicts two of these popular motifs—a lion and a tree—combined on one impressed discus (Fig. 1).

Most photograph cards contain representations of the objects, but they also record the object’s location, the photograph’s negative numbers, subject headings for the image or images on the object, and some bibliographic information. However, there are many temporary “Orange Cards” in the archive that contain only a bibliographic reference and a subject term, and these still await corresponding images. Their inclusion in the original system nonetheless provides important data points about the objects they describe, laying the groundwork for future cataloguers to source the images for these object records. For example, the Index’s photo archive of terracotta objects in the National Museum at Carthage is mostly Orange Cards because the original Index records of these objects derive from a 19th-century publication with very few illustrations. While it would be useful to see images of the “lions” held at the National Museum in Carthage, even in the absence of photographs it may be just as useful to know that, of the 970 terracotta lamps held in that location, nearly four hundred depict animals, and about sixty-five of those include a lion.

A Face in Gold Glass

The “Gold Glass” files record over 650 objects across sixty-three locations dating mostly from late antiquity between the 3rd and 7th centuries. Of these objects, nearly half are vessels of some kind. Gold glass developed as a medium in the ancient Roman and Hellenistic periods and consisted of decorative engravings made in gold leaf, which were then sandwiched between fused layers of glass. The result was lavish decoration, and exemplary pieces in this medium offer strikingly detailed portraits of their subjects, often depicting married pairs, family groups, or religious figures associated with one another, such as Saints Peter and Paul. Historians have noted the rarity of gold glass, as well as its costly, specialized method of production.[1]

Fig. 2. Gold Glass Busts of Married Pair inscribed GREGORI BIBE [E]T PROPINA TVIS (Rome, 200–299 CE). Museo Sacro della Biblioteca Apostolica Vaticana, Vatican City State (Inv. no. 743).

Gold glass was a special interest of Index founder Charles Rufus Morey, and his pioneering catalogue of the Vatican Library’s collections features as its first entry an example also catalogued by the Index. It shows the busts of a married couple inscribed above with the name Gregori and a Latin equivalent of “cheers!”: “Gregori bibe [e]t propina tuis,” or “Gregory, drink and drink to thine!” (Fig. 2).[2]

Fig. 3. Illustration of the gold glass portrait of “Sappo Flacillae” from the 1873 catalogue Histoire de l’art de la Verrerie dans l’Antiquité, pl. 43.

Another interesting discovery in the “Gold Glass” category was a round vessel fragment last recorded in the Cabinet des Médailles in Paris. It depicts a striking bust of a figure with shorn hair, dressed in a trimmed tunic, and with a distinctive crescent shape on their forehead. The only other information on the photograph card was the source of the image, the antiquities catalogue that Anne-Claude-Philippe de Caylus published in seven volumes from 1756 to 1767.[3] Caylus’s catalogue was a valuable starting point for identifying this figure, whose iconographic description had not been entered in the Index’s subject files or the database. A little more searching led to a color image in a French catalogue, the Histoire de l’art de la Verrerie dans l’Antiquité (Fig. 3), and to the conclusion that the inscription “SAPPO FLACILLAE”—with the genitive form of the empress’s name—referred to a branded enslaved person who had been freed by the Roman Empress Aelia Flacilla (356–386). We also used the photo-editing web application Pixlr to create a positive image of “Sappo” so that the image from the Index archive can now be seen as it appeared in the catalogue of the comte de Caylus (Fig. 4).

Impressions in Wax

Comprising a little over one thousand objects in 105 locations, the “Wax” medium files are overwhelmingly made up of stamps from Europe dating largely to the 13th and 14th centuries. Although the archive groups these objects into the single object category “Stamp,” the Index database divides them into two Work of Art Types, “Seal Matrix” (that is, the tool used to make the impression) and “Seal Impression” (that is, an impression made by a matrix).[4] Viewing about a thousand examples of Gothic seals intended for both religious and secular officialdom brought into literal relief the development of the production of seal dies from simple figural representations to complex ecclesiastical chapters in miniature, such as the Stamp of Ely Priory, dated to about 1240–1260 (Fig. 5). Other favored subjects in wax seals include heraldry, nobles, and popular saints and bishops, like Thomas Becket. The wealth of iconographic information in the “Wax” files—indeed throughout the archive—emphasizes that the Index is not a closed system, and has at every turn great potential for leading one into new areas of inquiry.

Exploring the Photographic Archive of The Index: Part 2

Precious Gems Containing a Wealth of Iconography

“Glyptic” is among the smaller medium categories in the Index archive, filling only one drawer with a little more than eleven hundred cards that record only about nine hundred objects. The term “glyptics” refers the art of carving gems or seals—whether in intaglio or in relief—typically in gems or precious stones such as jasper, agate, carnelian, and amethyst.[1] This form of art is one of the oldest—known since the Mesopotamian, Egyptian, and Assyrian civilizations—but it was not until the Hellenistic period that relief cameos, seals, and more intricate glyptic objects began to appear.[2]

Glyptics, which were often worn as jewelry or incorporated into ecclesiastical objects, are recorded in the Index primarily as gems, amulets, plaques, rings, and stamps, and the largest category, cameos, which makes up nearly a third of the glyptic objects in the Index files. A significant portion of the subjects on these carved gems include animals and plant life, like doves, dolphins, fish, palm trees, and fantastic creatures. There are other symbols as well, such as the anchor, which appears on over forty examples. A significant number of glyptics incorporate classical and mythological figures, such as Orpheus, Diana, Jupiter, and Hecate. Nearly twenty cards for gem objects record the Gnostic figure Abrasax (Fig. 1). Glyptics such as these were powerful talismans for their owners.

Fig. 2. Glass paste glyptic cameo of Theodore Tyro or Theodore the General, Slaying Dragon, 13th century. Athens, Benaki Museum (GE 13521).

The traditional use of spiritual amulets was also adopted by Christians using Christian symbols and themes.[3] Christian iconography on glyptics include the triumphant Archangel Michael or Saint George, Daniel in the Lion’s Den, and the Good Shepherd. One cameo of opaque black glass made in the 13th century depicts Saint Theodore transfixing the dragon and well represents the preference for saintly imagery on later cameos (Fig. 2).[4] The inventory also revealed that there were nearly thirty examples of incised depictions of monograms on glyptics with a third of them being the Chi-Rho, a symbol for Christ consisting of the first two letters of the word “Christos” (Christ) in Greek.

The major collections represented in this medium include the Staatliche Museen in Berlin (over eighty objects) and the British Museum in London (nearly 125 objects. However, a large number of glyptics (over 140 objects) are recorded as “Location Unknown,” these items having been entered into the Index from major publications that did not provide the precise location at the time of publication.

Radiant Ivories for Both Secular and Religious Narratives

With nearly forty-seven hundred cards covering a little over thirty-one hundred objects, Ivory represented a more extensive category in this inventory project. The types of ivory objects recorded by the Index range from plaques, chess pieces, croziers, and triptychs to the more unusual oliphant (or hunter’s horn) to the handles of various utensils, and even a saddle. Some of the major collections represented in this medium are the Musée du Louvre and the Musée de Cluny in Paris, and the British Museum and the Victoria and Albert Museum in London. Ivory objects were expertly carved in minute detail, usually from the tusks of elephants. In the Index database, ivory acts as a “parent medium,” an umbrella covering such materials as bone, walrus tusks, and antlers.[5]

Various motifs of courtly love were often depicted on ivory caskets, plaques, mirror cases, combs, and other fine domestic objects.[6] A preference for secular subjects on ivories emerged in the twelfth century when an influx of secular imagery was brought to Europe from the Middle East after the Crusades, as well as through a rise in vernacular literature, legends, and romances.[7] Entertaining stories such as the tale of the Virgin and the Unicorn provided plenty of thematic material to adorn precious ivory objects. They often offered a double meaning or moral lesson, as in the story of Tristan and Isolde depicted on an early 14th-century ivory casket now in the Metropolitan Museum of Art, which warns against temptations of lust (Fig. 3).[8]

Fig. 4. Ivory statuette of the Virgin Mary and Christ Child, Suckling Type, or Virgo Lactans, ca. 1325–50. New Haven, Yale University Art Gallery (1949.100).

Despite their popularity, secular ivories are fewer in number than devotional works of art in ivory. Roughly a quarter of the ivory objects recorded in the Index are representations of the Virgin Mary and the Christ Child. This figure rises to more three quarters when we add individual figures of Christ or the Virgin Mary. One type seen rather frequently is that of the Virgin nursing the infant Christ—known in Latin as the Virgo Lactans—which the Index categorizes among the many “types” of the Virgin Mary and Christ Child. In the database, the subject heading Virgin Mary and Christ Child, Suckling Type is attached to over 290 Work of Art records. More than forty of these are ivory. This Virgo Lactans iconographic type is exemplified by a 14th-century ivory statuette in the Yale University Art Gallery, which displays an intimate and lifelike relationship between mother and child (Fig. 4). Thus, the devotional message is made personal.

The Project Continues

Encompassing eight drawers of roughly one thousand cards each, “Painting” proved to be an abundant medium, but “Illuminated Manuscript” is by far the largest medium category in the Index, filling fifty-six of the photograph drawers. Medieval art objects encountered in these two categories range from painted icons and altarpieces to a wide variety of liturgical manuscripts and other illuminated books numbering perhaps in the thousands. The inventory of these and other remaining categories—including those comprising in situ works of monumental art, such as “Mosaic” and “Fresco”—will continue after this summer.

As a “living archive” that covers more than a millennium of artistic creation, the Index of Medieval Art has always been improved and expanded by the interactions of the cataloguers who create it with the with researchers who use it. Creating these inventories has been an illuminating way to participate in that process and to learn more about the contents of the Index card catalogue being prepared for entry into the online database. This project was challenging at times, due to the sheer breadth of the paper files, but it has been an invaluable undertaking for the ongoing process of research and digitization, and will improve accessibility to the records contained in this century-old archive of medieval art.

Encountering Medieval Iconography in the Twenty-First Century: Scholarship, Social Media, and Digital Methods

Organizers: M. Alessia Rossi and Jessica Savage (Index of Medieval Art, Princeton University)

Stemming from the launch of the new database and enhancements of search technology and social media at the Index of Medieval Art, this roundtable addresses the many ways we encounter medieval iconography in the twenty-first century. We invite proposals from emerging scholars and a variety of professionals who are teaching with, blogging about, and cataloguing medieval iconography. This discussion will touch on the different ways we consume and create information with our research, shed light on original approaches, and discover common goals.

Participants in this roundtable will give short introductions (5-7 minutes) on issues relevant to their area of specialization and participate in a discussion on how they use online resources, such as image databases, to incorporate the study of medieval iconography into their teaching, research, and public outreach. Possible questions include: What makes an online collection “teaching-friendly” and accessible for student discovery? How does social media, including Twitter, Facebook, and blogging, make medieval image collections more visible? How do these platforms broaden interest in iconography and connect users to works of art? What are the aims and impact of organizations such as, the Index, the Getty, the INHA, the Warburg, and ICONCLASS, who are working with large stores of medieval art and architecture information? How can we envisage a wider network and discussion of professional practice within this specialized area?

Please send a 250-word abstract outlining your contribution to this roundtable and a completed Participant Information Form (available via the Congress Submissions website: https://wmich.edu/medievalcongress/submissions) by September 15 to M. Alessia Rossi (marossi@princeton.edu) and Jessica Savage (jlsavage@princeton.edu). More information about the Congress can be found here: https://wmich.edu/medievalcongress.
