Nero's paternal line was Domitius Ahenobarbus...the cognomen means "red beard."
I'm shocked that they don't show Septimius Severus as a black man. After all, he was born in Africa.

Nero looks a bit like the p-whipped royal Harry
Constantine is a personal favorite - given the oddities of Roman leadership style, he was the first step into relative normalcy.
