For #ReliefWednesday the so called Gemma Claudia, made of five-layered onyx. Emperor Claudius and his forth wife Agrippina minor are depicted on the left, opposite her parents Germanicus - brother of Claudius - and Agrippina maior.
The cameo was presumably made on the occasion of Claudius' and Agrippina's wedding in 49 AD.
Agrippina was the mother of Nero. It was rumoured that she poisoned her husband and uncle Claudius with a dish of mushrooms

On display at Kunsthistorisches Museum Wien
