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.

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]

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.
