A 19th c. gold pair of earrings with agate cameos. Masks.

Each earring features a 4-layered agate cameo depicting a theatrical mask of bearded Silenus with a bow or crown of wine leaves on his forehead. In the background two faces joined together: young and old; young man with another young man. Both cameos appear to be sculpted by the same artist for the same set. The iconography recalls that of the Grylloi, and can be referred to both the theatrical and Dionysian spheres. 
Signs of wear.
