died before the reign of Caligula. Cultural depictions Many scholars think the Ara Pacis (an altar from the Augustan Era), displays Gnaeus Domitius Ahenobarbus and his elder sister. The woman behind Domitia and Domitius is allegedly their mother Antonia Major and the man next to Antonia Major is her husband Lucius Domitius Ahenobarbus. Ronald Syme has argued the two children are actually the elder son Lucius and another unknown sister.
