Finger rings have survived in greater numbers than other Byzantine ornaments. The majority are figured with the beautiful symbolism of the Christian belief. Some are set with engraved gems, but on most the design is produced by the more simple process of engraving the metal of which the ring is composed. In early Christian times rings were often offered as presents, and were engraved with expressions of good-will towards the recipient, whose name is sometimes mentioned. The British Museum contains a somewhat extensive collection of these rare objects in gold. Bronze, often gilded, is naturally the commoner material. Silver appears to have been scarcely ever employed. The interest of the majority of Byzantine rings arises rather from the subjects with which they are associated, than from the quality of their workmanship. There is, however, in the British Museum a very beautiful example of pierced gold work in the form of a key ring with projecting tongue, of a kind much used in Roman times, which opened the lock by lifting a latch. Upon the front of a wide hoop are the words _Accipe dulcis_, in letters reserved in metal in a pierced ground. The remainder of the hoop is divided into compartments, each containing one letter of the inscription _Multis annis_. Above the inscription, in front, is a rectangular projection, perhaps for insertion into a lock. It is finely pierced with a design in the form of Greek crosses (Pl. IX, 10). The sack of Constantinople by the French and Venetians dealt the death-blow to Byzantine art. Until well into the thirteenth century the Byzantine goldsmiths continued to exercise an important influence on their contemporaries, and transmitted to the artists of mediæval Europe such of the processes and designs of antique art as they had preserved. Their intercourse was closest with Russia, whose jewellery for centuries, even up to the present day, has followed the designs of the old Byzantine workmen. CHAPTER VI PREHISTORIC (CELTIC) JEWELLERY ROMANO-BRITISH JEWELLERY The early ornaments of the greater part of Europe remained until late times entirely untouched by the culture prevalent in Italy and Greece. Though of great archæological importance, as revealing successive stages of culture, they do not at the present demand very detailed consideration. The decoration of the earliest jewellery of Europe--that of the Bronze Age, which dates roughly from about a thousand years before the Christian era--is by means of spiral and zigzag patterns. Ornaments have free endings, bent in spiral, snail-shell coils. The earliest were cast, though the hammer was used towards the close of the period; solder was unknown, and rivets alone employed. Gold and bronze were the only metals employed, the latter being sometimes gilt by means of thin gold plates, while amber is often found used as a jewel.
