Ca. 100-300 AD. An oval-shaped carnelian intaglio engraved with a striking left-facing portrait of Jupiter, the ruler of the heavens and the god of thunder. The portrait is executed with remarkable skill and attention to detail. The god's regal features are masterfully carved, with a full beard, strong jawline, and piercing eyes that gaze out with an air of authority. The god's hair is neatly arranged in waves, with locks framing his face.Size: L:12.7mm / W:10.5mm ; 0.73gProvenance: From the private collection of Mr. R.
