It was minted after Caesar Augustus wrested the power seat from Brutus, and this symbol on the back is meant to demonstrate the direct patrilineal line to his late uncle/adoptive father, Julius Caesar.
I like this quote of Octavian’s: “I like treachery, but I cannot say anything good of traitors.” I take it to mean that political gamesmanship is one thing–even fun–but downright dirty players are another.
You know what I like even more? That the regal sunburst looks like this diatom. I love unintended symmetry in manmade objects and the natural world.
