Sulla himself emphasized his title of “Imperator”, or later on a smaller issue “Dictator”, on the coins made in his life time in his name. Neither role appears on the remarkably numerous posthumous commemorations he receives on the coins. Q. Pompeius Rufus is celebrating his maternal and and paternal grandfathers, the consuls of 88 BC. And it is the shared consulship itself that receives emphasis. The two are treated as equals.
Yet, his paternal grandfather of the same name was murdered as consul, allegedly by Pompieus Strabo, Pompey the Great’s father, when he went to take over Strabo’s army as his duly assigned province of Italy. That sort of murder surely created some tension between their descendants. The two headed type was produced by far fewer dies than the curule chairs (according to Crawford — I’ll want to check the accuracy of this). The later gives even more emphasis to the legal office and authority of each ancestor, along with indications of their priesthoods. It tries to invoke Sulla and Rufus as exempla of law and order.
Sulla’s son, Faustus, takes a very different approach:
He refers to his father only as FE(E)LIX, the remarkable agnomen, adopted upon his Civil War victories in 82 BC, meaning something like ‘Blessed’, not dissimilar from the meaning Faustus’ own name. The imagery of one type harkens back to Sulla’s first success, the surrender of Jugurtha, while just Marius’ quaestor, an image that served as his father’s seal and the famous Bocchus monument. The rest recalls his divine patronage, an issue we’ve talked about before. He may also be trying to emphasize a close relationship between Pompey, his close ally, and his father.
This type shows Venus Victrix to whom Pompey dedicated the very next year his huge theatre complex and an image of Pompey’s seal ring, but of course it was a seal ring very close to Faustus’ father’s and Venus played a prominent role in his father’s life as well.
[I’m going to skip talking about RRC 480/1 as you can read about it in my earlier post to which I put a link above, even though it properly fits into this topic. I’m also skipping over the Sulla-Hercules connection as all I’d be doing at this point is parroting Crawford.]
