The art of glyptics, or carving on colored precious stones, is probably one of the oldest known to humanity. Intaglios, gems with an incised design, were made as early as the fourth and third millennia B.C. in Mesopotamia and the Aegean Islands. The exhibit a virtuosity of execution that suggests an old and stable tradition rooted in the earliest centuries. The tools required for carving gems were simple: a wheel with a belt-drive and a set of drills. Abrasives were necessary since the minerals used were too hard for a metal edge. A special difficulty of engraving intaglios, aside from their miniature size, was that the master had to work with a mirror-image in mind.

The Classical Revival was a phenomenon that swept through Europe in the 18th and 19th Centuries. A new appreciation for antiquity and ancient art forms was fostered by discoveries in the nascent scientific field of archaeology. Perhaps the Classical Revival also reveals a latent longing towards the Arcadian lifestyles of yesterday abandoned as Europe became rapidly industrialized and increasingly urbanized. On the polished surface of this precious stone, an image of the bust of a Roman Emperor has been carefully engraved. His curly hair, long flowing beard, and radiate crown are all attributes associated with the emperors of the mid-third century A.D. This profile portrait was likely base upon a bust depicted on the obverse of a Roman coin. Perhaps the artist uncovered such a relic while exploring the ruins of Italy during a tour of Europe?
