Sardonyx cameo of a double capricorn with a portrait of the emperor Augustus

An item at Metropolitan Museum of Art

The cameo bears a medallion with a portrait of Augustus supported on the horns of a double-headed goat. The imagery represents the constellation Capricorn, which was adopted by the Emperor Augustus as his own lucky star sign and was used as an imperial symbol on such things as coins and legionary standards.

Greek and Roman Art

An exhibit at Metropolitan Museum of Art

The Museum's collection of Greek and Roman art comprises more than thirty thousand works ranging in date from the Neolithic period (ca. 4500 B.C.) to the time of the Roman emperor Constantine's conversion to Christianity in A.D. 312. It includes the art of many cultures and is among the most comprehensive in North America. The geographic regions represented are Greece and Italy, but not as delimited by modern political frontiers: Greek colonies were established around the Mediterranean basin and on the shores of the Black Sea, and Cyprus became increasingly Hellenized. For Roman art, the geographical limits coincide with the expansion of the Roman Empire. The department also exhibits the art of prehistoric Greece (Helladic, Cycladic, and Minoan) and pre-Roman art of Italic peoples, notably the Etruscans.
