The term intaglio refers to a small image that has been engraved into a gemstone and usually set in a piece of jewellery, most commonly a ring. Such artistic form has its origin in Sumer in the 4th millennium BC, with the appearance of cylinder and stamp seals, whereby decorations and patterns were engraved into soft stones. During the Hellenistic period and the early Roman Empire, the art of intaglio reached its apogee, with there being a steady decline in craftsmanship in the late Imperial Rome, until a revival of interest with the Byzantine and during the Renaissance.
During the Roman Empire, horses were extremely important for battle, as well as for aspects of everyday life, such as transportation, hunting, farming, and chariot racing. The Romans associated the horse with the spoils of war, connecting it symbolically with power, victory, honour, domination, and virility. In Graeco-Roman mythology and culture, the horse was said to have been created by Poseidon (Neptune) and devoted to Hades (Pluto) and Ares (Mars). The Romans also believed the horse to be a symbol of the continuity of life, and would sacrifice a horse to the god Mars every October, keeping its tail through the winter as a sign of fertility and rebirth.
