Quote: He was a total nutbag.
First century BC Rome was a strange place. It's hard to convey into English exactly what a Roman meant by "dignitas" but Lucius Cornelius Sulla was a scion of the Cornelii, an old Patrician powerhouse whereas Marius was a plebian. Who can know what Sulla thought of that or what slight to his dignitas he imagined from this low-born scum?
Curiously, when Caesar fought Pompey, Caesar was the Patrician representing the populaires while Pompey was the plebian representing the optimates. Civil War has a way of fucking things up.
