Byzantine enamel
The craft of cloisonné enameling is a metal and glass-working tradition practiced in the Byzantine Empire from the 6th to the 12th century AD. The Byzantines perfected an intricate form of vitreous enameling, allowing the illustration of small, detailed, iconographic portraits.
Overview
The development of the Byzantine enamel art occurred between the 6th and 12th centuries.[1] The Byzantines perfected a form of enameling called cloisonné, where gold strips are soldered to a metal base plate making the outline of an image. The recessed spaces between the gold filigreed wire are then filled with a colored glass paste, or flux, that fills up the negative space in the design with whatever color chosen. Byzantine enamels usually depict a person of interest, often a member of the imperial family or a Christian icon. Enamels, because they are created from expensive materials such as gold, are often very small. Occasionally they are made into medallions that act as decorative jewelry or are set in ecclesiastical designs such as book covers, liturgical equipment like the chalice and paten, or in some examples, royal crowns. Collections of small enamels may be set together to make a larger, narrative display, such as in the Pala d'Oro altarpiece.[2]
Many of the examples of Byzantine enamel known today have been repurposed into a new setting, making dating particularly difficult where no inscriptions or identifiable persons are visible. The
Origins
The art of vitreous enameling is an ancient practice with origins that are hard to pinpoint.[4] There are a few places that Byzantine craftsmen could have picked up the technique. Enameling is thought to have existed in an early form in ancient Egypt, where examples of gold ornaments containing glass paste separated by strips of gold have been found in tombs.[5] However, there are questions about whether the Egyptians were using actual enameling techniques; it is possible that instead they were casting glass stones which were then enclosed, set into metal frames, and then sanded to a finish, similarly to how precious stones are set.[6] In first century BCE Nubia, a method appears of soldering gold strips to a metal base, most often gold, and then filling in the sectioned off recesses with glass flux. This method, called cloisonné, later became the preferred style of enameling in the Byzantine Empire.[7]
The enamel workshops within the Byzantine Empire likely perfected their techniques through their connections with Classical Greek examples.[8] The Greeks were already experts in enameling, soldering a filagree onto a flat base and later adding a paste of glass, or a liquid flux, to the base piece.[9] The entire work was then fired, melting the glass paste into the frame to create the finished work. Occasionally, the ancient Greek craftsman would apply the glass flux to the base with the aid of a brush.[10] The Romans, who were experienced in glass production already, would carve a recess into the base plate and then pour glass flux into each enclosure.[11] The metal peeking through between the recessed glass would create the outline of the image. This technique is called champlevé, and is considerably easier than the cloisonné form of enameling practiced by the Greeks and Byzantines.
Byzantine enamel tradition
The Byzantines were the first craftsmen to begin illustrating detailed miniature scenes in enamel. A few examples of early Byzantine enamel frames missing the glass flux have been found, and it has been hypothesized that they were used as educational tools in workshops. Some incomplete enamel base plates show indentations marking the line to which the gold wire would be attached, indicating how designs were outlined before soldering and enameling began. Because they were not carving recesses into a base plate and then filling the hole with glass flux, Byzantine workers could also use gold wire to create patterns that would not separate recesses from one another, resulting in a style that appears more like a drawn line.
Most of the Byzantine enamels known today are from the 9th to 12th centuries. The period of Iconoclasm from 726 to 787 AD meant that most examples predating the 8th century were destroyed because of their iconographic nature, though there are a few examples thought to have been made earlier.[12] One of the earliest examples of Byzantine enamel work is a medallion created in either the late 5th or early 6th century and features a bust portrait of Empress Eudoxia.[13] The period after Iconoclasm saw an upswing in the production of iconic portraits, to which the intricate form of cloisonné developed by the Byzantines lends itself easily. Most enamel works known today have been housed in western Europe since the beginning of the 13th century. Any examples of enamel work still inside Constantinople immediately prior to its destruction were lost or destroyed.[14]

Beresford Hope Cross
The Beresford Hope Cross is a pectoral cross intended for use as a reliquary.[25] On one side Christ is depicted at the Crucifixion, while the other shows Mary praying between busts of John the Baptist, Perter, Andrew, and Paul. The dating is contentious, but most agree it was made in the 9th century.[26] The style is similar to the Fieschi-Morgan Staurotheke; the cloisonné of both is unrefined and stylistically sloppy compared to other examples. The inconsistencies in the Greek lettering on the cross mean that it is possible the piece was not made in the Byzantine Empire, but in southern Italy, where the Lombards had active metal workshops of their own.[27]

Problems with dating and origins
Many examples of Byzantine enamel are hard to date because of a lack of inscription or identifiable individual. In these cases, guesses must be made to the date of the object in question through a comparison with similar objects with known dates. This can be done by examining material sources and by comparing styles. For example, objects with green glass composed of similar material might be grouped within a similar date range. Origins of Byzantine enamel work are often even harder to pinpoint, as nearly everything made has been housed in the West since the early 13th century. One way of guessing the origins of a piece is by examining the quality of the Greek lettering; the more accurate the Greek, the more likely the work came directly from the Byzantine Empire.
