Neo-classical Cameos. Neoclassicism is a revival of the styles and spirit of classic antiquity inspired directly from the classical period,which coincided and reflected the developments in philosophy and other areas of the Age of Enlightenment, and was initially a reaction against the excesses of the preceding Rococo style. While the movement is often described as the opposed counterpart of Romanticism, this is a great over-simplification that tends not to be sustainable when specific artists or works are considered. The case of the supposed main champion of late Neoclassicism, Ingres, demonstrates this especially well. The revival can be traced to the establishment of formal archaeology. Reference: Wikipedia
Many gems were carved in the neo-classical style popular in the late 1700s and early 1800s, when taste in the arts echoed the subject matter and style of the Greek and Roman masters. Thousands of gems were made in this style in Italy and brought back by British Grand Tourists, who went there to visit the newly-discovered classical antiquities and archaeological sites.
