The connection between four cardinal virtues and Hellenistic kingship was a new idea to me. (I feel a little ashamed to admit this!)
I’ve been re-reading Katherine Steel’s Cicero, Rhetoric and Empire (p. 133) and this passage struck me:
How does this connect with the shield of virtues presented to Augustus by the Senate? Surely someone must have written something on this. I’m going to resist exploring at this moment and just leave this note for myself that I wish to revisit the topic, at least before the next time I teach the clipeus virtutis!!
