The New Mithraeum
9 Jan 2023
The setting is divided into two parts. In the lower register, Parthian and Germanic captives. In the second register, the emperor Augustus, his head veiled and wearing a radial crown, is surrounded by Germanicus, mounted on a winged horse, and Tiberius' son, Drusus the younger. The floating figure dressed in oriental style, carrying a globe in his hands, could be Aeneas. The centre of the gem is reserved for Tiberius enthroned with his mother Livia; he is presiding over a solemn ceremony presumed to be the designation of Nero (standing in arms before him) as Prince of Youth in AD 23.
