In 1986 the Walters Art Museum purchased a silver Byzantine ring from the Günter Puhze gallery in Freiburg, Germany (fig. 1). The ring, dated to the sixth or seventh century CE, consists of a narrow convex band and a raised circular bezel with an incised design in reverse. This design features a monogram composed of Greek letters, a cross, and two palm fronds, enclosed with a beaded frame. The reverse incised form of this design indicates that the ring functioned as a signet. The wearer would have pressed the bezel into a bed of soft wax leaving behind a mirror image, relief impression, or seal, that could be attached to letters, contracts, and personal property for authentication and protection.
The ring is exhibited at the Walters in the gallery of Early Byzantine art and is accessible on the Walters’ website. The only substantial publication on the ring is found in the 2011 book, The Medieval World: The Walters Art Museum, by Martina Bagnoli and Kathryn Gerry. This catalogue of nearly 150 objects serves as a guide to the medieval collections and an introduction to the material culture of the Middle Ages. The short entry on the ring erroneously states that the monogram is composed of Latin letters, which translate as “of Mark.” The Walters’ website corrects the first error, indicating that the monogram is composed of Greek letters, but maintains the reading “of Mark.” This research note demonstrates that the monogram identifies the wearer as “Akakios,” and then shows that the misattribution reflects the ways in which signet rings have been studied and presented in publications and museum exhibitions.
A monogram is part text, part image. The letters of a name, title, word, or phrase are isolated, rearranged, and combined into a single graphic device. Monograms became a notable feature of late Roman aristocratic culture in the fourth and fifth centuries CE, when prestigious families and high-ranking civic officials had their monograms inscribed on ivories, silver plates and spoons, and signet rings. Many of these unique symbols were—and still are—difficult to decipher, which appealed to the members of the elite who used monograms as markers of their social status and presumed intellect. Quintus Aurelius Symmachus (ca. 345–ca. 402 CE), a Roman statesman in the late fourth century, wrote that his monogram was “more to be understood than to be read.” His family’s monogram is found on the so-called Consecratio panel (ca. 402 CE), one half of an ivory diptych that depicts the funeral and apotheosis ceremony of Quintus Aurelius himself (fig. 2). The monogram, inscribed at the center of the upper frame, combines the Latin letters of his family’s name in the genitive case (a function of grammar marking possession or association): SYMMACHORUM (“of the Symmachi”). Personal monograms typically render the name in the genitive, indicating that the symbol, and the object upon which it is inscribed, belong to the named family or individual.
Monograms first appeared in public monumental settings in Constantinople during the sixth century CE. The late Roman imperial princess Anicia Juliana (461/3–527/9 CE) had a variety of personal monograms carved in the marble piers of the church she commissioned in Constantinople, Hagios Polyeuktos; just a decade later, monograms naming the Eastern Roman Emperor and Empress Justinian I and Theodora (reigned 527–565) were likewise carved into the architecture of the monumental cathedral Hagia Sophia, specifically the basket capitals atop its columns (fig. 3). Paul the Silentiary (died 575–580) in his dedicatory ekphrasis of the cathedral describes one such monogram: “the carver’s tool has incised one symbol that means many words, for it combines the names of the Empress and Emperor.”
Monograms of this late antique period are of two types. The first, used primarily between the fifth and seventh centuries, is known as the block monogram. This type is based on a central block-shaped Latin or Greek letter, such as H, M, N, or Π, with other letters written around and attached to it. The monogram of Symmachus is an example of this type, in Latin, for which the M forms the central block. By the middle of the sixth century, designers gave preference to a different type, known as the cruciform monogram. This type is composed predominantly of Greek letters that form part of, and are attached to, the arms of a cross. An example of a cruciform monogram that reads ΙΩΑΝΝΟΥ (“of John”) is incised on the bezel of the gold signet ring of the Zucker Family Collection, on loan to the Walters (fig. 4).
Returning to the silver signet ring, we can recognize that the monogram is of the block type. The 1985 sale catalogue at Günter Puhze identified the central block letter as M. The gallery’s identification most likely influenced the Walters’ initial reading of the monogram as MAPKOY (“of Mark”), an interpretation that is problematic. According to this reading, the A and Y would be upside down vis-à-vis the central M; the K, when impressed, would read backwards; and the P is nowhere to be found (fig. 5). It is not unprecedented for a block monogram to feature backwards or upside-down letters, but in such cases, it was done to accommodate more letters within the design. To correct this reading, we must rotate the bezel 180 degrees. In this orientation, the central block is formed by an A at the base and two vertical lines surmounted by the letters Y and O. The only asymmetrical letter, K, noticeably in reverse, extends from the left vertical line. Having correctly oriented the ring (fig. 1), the palm fronds are properly upright with the stems positioned at the lower end of the design and the leaves curving upward. The cross is also more appropriately positioned at the upper half of the design, rather than below the monogram. The drawing below presents the impression the signet would leave on items it sealed (fig. 6).
A similar block monogram is found on ten glass weights, dated to the sixth century. One of these weights, at the British Museum, is made of blue glass and features a circular impression that consists of the monogram in the lower half of the medallion and an unidentified figural bust between two crosses in the upper half (fig. 7). This monogram is formed by the Greek letters Α, Ι, Κ, Ο, and Υ, which Walter Fink and Chris Entwistle have read as the name ΑΚΑΚΙΟΥ (“of Akakios”). Therefore, the same reading can be offered for the monogram on the Walters silver signet ring; however, there is no evidence that the same Akakios can be linked to the ring and any of the glass weights.
How is it possible that the monogram on the Walters silver signet ring was misidentified? Monograms are difficult to read because there can be many solutions to any single design. The Walters silver signet ring presents two particular challenges. One, reading this, or any, monogram is aided by the study of other monograms, regardless of where they occur or how they function: while the Akakios monogram has not yet been found on another signet ring, it is present on each of the ten glass weights mentioned previously. Two, the monogram is in reverse. If one looks at a monogram while holding a signet ring but is not expecting the monogram to be displayed in reverse, the impulse can be to rotate the object 180 degrees so that letters in reverse appear correctly oriented; a backward K, for example, would then appear properly oriented to the eye, but would lead to a misidentification of the other letters in the monogram.
These two challenges are reflected in publication and exhibition. The incorrect reading and inverted image of the bezel in The Medieval World, mentioned previously, likely determined the ring’s orientation in the Early Byzantine gallery at the Walters, where, at the time of writing this essay, it was displayed next to the gold signet ring of John—both with their bezels rotated 180 degrees. This inaccurate orientation is by no means unique to the Walters. A gold signet ring at the British Museum, dated to the sixth century, features a block monogram, which I suggest may read ΕΛΙΣΣΑΙΟΥ (“of Elissaios”) (fig. 8). When the ring was first published by Ormonde Maddock Dalton in 1901, an accompanying illustration of the monogram was properly oriented. However, the photograph of the ring posted on the museum’s website presents the bezel rotated 180 degrees; the presence of the metric scale within the image makes it clear that the ring was photographed in the incorrect orientation. The 2006 catalogue, The Road to Byzantium: Luxury Arts of Antiquity, published in conjunction with a joint exhibition between the State Hermitage Museum in Saint Petersburg and the Courtauld Institute of Art in London includes descriptions and photographs of three seventh-century gold rings from the Pereshchepina Treasure—a group of over 800 early medieval artifacts discovered in Ukraine in 1912—that may name the khans of Great Bulgaria, Organa and Kuvrat. All three rings are inscribed with monograms, two of which are in reverse, indicating that these two rings functioned as signets. In the accompanying photographs, the two signet rings are shown with their bezels rotated 180 degrees, while the other ring—whose monogram is not in reverse—is properly oriented. The Hermitage repeats this error on their website.
Signet rings inscribed with longer Christian invocations on their bezel—a feature of Byzantine signet rings from the eighth century and later—have also been exhibited with their bezels rotated 180 degrees. An example is the sole signet ring included in the 2016 catalogue Sceaux de la collection George Zacos au Musée d’art et d’histoire de Geneve.The reverse inscription is displayed in five lines and provides the name of the wearer, his imperial title of spatharios (sword-bearer), his office of strategos (general), and his jurisdiction at the southern coast of Asia Minor: “Lord help Theophilos, the imperial spatharios and strategos of Kibyrrhaiotai.” The catalogue entry is illustrated with two photographs, one of which focuses on the bezel inscription rotated 180 degrees (fig. 9). This error is notable considering that the volume catalogues 460 inscribed objects. However, the signet ring of Theophilos is fundamentally different from the lead seals that are the primary subject of the book. Whereas the ring was used to make impressions and is thus inscribed with a reverse inscription, the lead seals are impressions and thus feature inscriptions and monograms displayed in proper reading orientation.
These examples in publications, museum galleries, and websites reveal the challenges inherent to studying monograms and inscriptions on signet rings. These objects have been examined primarily by scholars of sigillography (the study of seals), who are trained to study the impressions of inscriptions, and by art historians of jewelry, for which the inscriptions tend to be of secondary concern to materials and techniques. Signet rings present unique challenges that are related to, but distinct from, lead seals and other forms of jewelry. They require an integrated methodology informed by many disciplines, and demand their own approaches of viewing, analysis, and display.
