WHO'S THE BROAD?

I'm in court almost every day of the year and above the judge in every single courtroom of California is this State Seal. I only ever notice it when the judge reads Jury Instructions to the jury. When I looked at it recently it really threw me. Who is that lady dressed up like a Roman soldier? I looked it up and see it's Minerva the Roman goddess of "Wisdom". There has got to be a punch line but it's eluding me.
