The interpretation of the family group alters with the date given to the gem. In the upper level are its deceased or deified members including
Divus Augustus. The surrounding figures may be
Drusus the Younger (son of Tiberius), and
Drusus the Elder (brother of Tiberius) flying on
Pegasus. In the middle level appear the emperor
Tiberius flanked by his mother
Livia; standing in front of them are
Germanicus, Tiberius's designated heir, together with his wife
Agrippina the Elder, behind them the future emperor
Nero and the figure of
Providentia (Foresight); behind Livia and Tiberius are
Claudius, emperor if the cameo was made in –54 AD, and his wife
Agrippina the Younger. Agrippina the Younger's hairstyle seems to confirm a date for the cameo between her marriage to Claudius in 49 AD and the accession of her son Nero as Rome's fifth emperor in 54 AD. Alternatively, the cameo was commissioned to celebrate Tiberius's adoption of his grandchildren, the sons of Germanicus, as heirs in 23 AD, and the dynastic stability it ensured, comparable to the earlier adoption of Germanicus by Tiberius in 4 AD, also referenced on the cameo and in the
Gemma Augustea. In the lowest level are captive
barbarians. ==History==
