Gemma Claudia

Gemma Claudia is an ancient cameo carved in about 49 CE from five-layer sardonyx, a variety of onyx with parallel reddish layers of carnelian. It depicts members of the Roman Julio-Claudian dynasty in a carefully balanced composition with two double cornucopias, an eagle, and four portraits emerging from the stone. Claudius and his fourth wife Agrippina the Younger appear on one side, while Germanicus and Agrippina the Elder are shown opposite. The work was likely made to commemorate the emperor’s wedding. It later belonged in the 17th century to the Habsburg Holy Roman Emperors and is now kept in the Kunsthistorisches Museum in Vienna, where it remains set in an 18th-century gold mounting.
