I thought it was a super
portrait as well. In fact, if you look in my
gallery and compare
his portrait to
his father's, you'll see a resemblance. First look at the
Decius bust, then the
Decius portrait (which, IMO is very similar and, thus, pretty accurate), and finally at Herrennius'
portrait on my coin (not the middle pic), and you'll see the family resemblance (at least I do particularly in the nose/mouth). That is why I bought this coin even though I was not looking for one of
his in particular. I was honing in on a
Caracalla, but that will have to wait...
