Ca. 300 - 400 AD. A gold ring composed of a thin hoop with pairs of spheres to the bezel, boasting an intaglio that depicts the god Mars seated on the back of a majestic eagle. In Roman mythology, Mars was the god of war and one of the most important deities in the pantheon. He was the son of Jupiter and Juno and was often depicted as a warrior with a spear and shield. His association with the eagle, a powerful and noble bird, was likely inspired by the Roman army's use of eagles as emblems of their legions. Roman intaglios depicting gods and goddesses were popular adornments for rings, often worn as symbols of protection and guidance. These intaglios served not only as decorative pieces but also as powerful amulets that could bring the wearer good fortune and protection from harm. The intricate designs and rare subjects of these intaglios make them highly sought after by collectors and historians alike, offering a glimpse into the rich and complex world of ancient Roman mythology and belief systems.Size: D: 17.53mm / US: 7 / UK: O; 3.64gProvenance: Private London collection, UK art market before 2000.
